--[[User:Z8600021|Mark Hill]] ([[User talk:Z8600021|talk]]) 11:26, 25 September 2015 (AEST) OK this is such an easy project to find resources for, so where are they? Everyone in research, support groups, genetic inheritance are talking about this topic and the techniques. But this is not on your project page.&lt;br /&gt;
 Like my comments for the other project pages, animal models and media, graphics, statistics, graphs to support the project information???? Your project is not ready for peer review.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
--[[User:Z8600021|Mark Hill]] ([[User talk:Z8600021|talk]]) 16:26, 1 September 2015 (AEST) I would like to see some content (sub-headings) on your project page.&lt;br /&gt;
&lt;br /&gt;
==Peer Reviews==&lt;br /&gt;
&lt;br /&gt;
===1===&lt;br /&gt;
&lt;br /&gt;
I’ll start by saying, you have an extremely extensive list of references.  Well done! It shows you have really done your research and made good use of it. Your citations are consistent throughout the page and most paragraphs have multiple sources. I would suggest to perhaps include a hand-drawn image somewhere on the page as well as a video. Aside from the section “biopsy methods”, the page could use a few more illustrations. From what I can see, the image under the subheadings “FISH” and “future/current research”, does not appear to have been added correctly according to the guidelines Mark gave us a few weeks back. There is no caption for the image like there are for the other images.&lt;br /&gt;
&lt;br /&gt;
I really like, how under the “diagnosis” heading, you have made the table of applicable diseases for PGD an expandable table. It helps keep the page clean and easier to control. Perhaps though add a little blurb below the table describing it. You have a great set of heading and subheadings that all relate back to your topic. Given that, you have addressed all important areas pertaining to your topic. May I suggest, that in the introduction section, which I am assuming is yet to be done, you add some epidemiological information and perhaps a video speaking briefly on the topic as it can be quite complex.&lt;br /&gt;
&lt;br /&gt;
Well done on the section titled “future/current research”. It is really useful for students seeking a higher degree of information on this topic as it goes into great detail. However, some direct references in the text to some papers would be good. I also suggest adding a glossary of words to the bottom of the page to cater to those who read the page, with a lower level of embryology knowledge than you or I. In addition to that, it may be good to try and break-down some of your paragraphs as there is a lot of text and it can be hard to take in for some people. Bullet points and tables are great. The page does however, focus well on embryological learning aims. &lt;br /&gt;
&lt;br /&gt;
Lastly, to conclude, I feel a though the table and image under “biopsy method” is a little cluttered and could be spaced out a bit more. Overall, this is a really good and detailed framework and with a little more work will be a great project.&lt;br /&gt;
&lt;br /&gt;
===2===&lt;br /&gt;
A very snazzy wiki page so far! You have used a wide variety of images to convey the concepts of prenatal genetic diagnosis to those reading your wiki page. Copyright information and student templates were present for all the images which you provided which is great to see. A hand drawn image is absent, which is a requirement for every wiki page. It might be worth including the hand drawn image in the 'history section' as the information here could easily be represented by a hand drawn flow chart.&lt;br /&gt;
&lt;br /&gt;
I commend you on your inclusion of a 'future/current research' subheading as this gives the reader a perspective of where the field of prenatal genetic diagnosis is heading in the distant future.&lt;br /&gt;
&lt;br /&gt;
I see that you have included a table underneath the 'biopsy methods' subheading. It would be great to see you compile the advantages and disadvantages of blastomere biopsy and trophectoderm biopsy into a tabular format as this would make for an easier reading experience. Furthermore, tables may also be incorporated for the disadvantages and advantages of genetic techniques.&lt;br /&gt;
I would recommend the inclusion of other forms of media such as a video or gif to assist in the conveyance of information under certain subheadings. A video/gif would fit nicely underneath the 'biopsy method' subheading, though this is just a suggestion.&lt;br /&gt;
&lt;br /&gt;
Overall your assignment is superb so far. You have successfully covered a vast topic and made successful use of a broad range of sources to support your page. Your inclusion of images has been appropriate, however a hand drawn image is still required. &lt;br /&gt;
Keep up the good work guys! &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===3===&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''COMMENDATIONS'''&lt;br /&gt;
&lt;br /&gt;
•	Good reference list and in text citations throughout.&lt;br /&gt;
&lt;br /&gt;
•	Great table of advantages and disadvantages under “Biopsy Methods” (good comparison of the techniques). However, the ‘Blastomere’ row is missing information.&lt;br /&gt;
&lt;br /&gt;
•	All key points have been addressed, and it is evident that you have done a lot of research!&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''RECOMMENDATIONS'''&lt;br /&gt;
&lt;br /&gt;
•	A short definition at the beginning of your page would help the reader understand what your topic is about. I was a bit unsure as to what ART was when I first began reading.&lt;br /&gt;
&lt;br /&gt;
•	Your information could be organised under more subheadings, particularly in your “Polar Body Analysis” section; the information here is quite dense. &lt;br /&gt;
&lt;br /&gt;
•	More pictures or animations would be great; make sure you reference your pictures properly as well (the image under FISH is missing a reference). &lt;br /&gt;
&lt;br /&gt;
•	More tables – a lot of your information involves advantages and disadvantages. You could create more tables to make the information easier to read/follow. It would also allow you to cut down on details that are repeated, or those that you do not need.&lt;br /&gt;
 &lt;br /&gt;
•	A self drawn diagram is also missing – maybe this could take the form of a world map and you could label the various countries featured under your “Laws &amp;amp; Legal Status” heading with their respective laws. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
It is evident that you have put in a lot of effort into your page. Try and condense the information you have, and add more titles and images to create a more succinct end product. Good job so far!&lt;br /&gt;
&lt;br /&gt;
===4===&lt;br /&gt;
&lt;br /&gt;
This page contains a lot of interesting information regarding the chosen topic, and has been accompanied by some really useful images. I was particularly intrigued by the information you have provided for genetic techniques and hope to see some more images and videos to help your explanation. Especially for PCR, this is a widely used technique for genetic analysis and I am sure there are some really good videos on YouTube you can add to this section. For these procedures, you have also listed a great amount of disadvantages and advantages but it would be easier to read if this were in a table format. &lt;br /&gt;
&lt;br /&gt;
I believe the headings are extremely relevant and cover the correct areas of focus for this topic. However, the use of sub-headings is lacking which makes it difficult for the reader to initially understand the areas that will be discussed on this page. You can easily change the bolded headings under “Indications”, “Preimplantation Genetic Screening”, and “Biopsy Methods” into subheadings with a minor edit. On that note, the table presented in the “Biopsy Methods” is quite confusing as the advantages and disadvantages of “Blastomere” are absent. Also, further elaboration on these headings is needed for the reader to gain an adequate understanding of the topic. &lt;br /&gt;
&lt;br /&gt;
You have provided a really good framework to add more content on this page. This is especially required in your heading of “Diagnosis”. I think a more detailed explanation about how the diseases are linked to PGD is needed to avoid confusion. When I first read it, it didn’t make much sense so perhaps use an image of how these diseases relate to PGD could mend this. &lt;br /&gt;
&lt;br /&gt;
The addition of a “Future/Current Research” heading is very well done. This demonstrates you have thought beyond the mechanics of describing PGD and are looking into extra sources. You may want to consider separating future research from current research to make the page more systematic, and to clearly show what scientists are looking to achieve later. The image in this section is also really good as it is clear and shows the process of extraction. More images, videos or GIFS may be needed to effectively convey the research and procedures to your audience. &lt;br /&gt;
&lt;br /&gt;
Lastly, your reference list is extremely impressive. You have shown you have conducted numerous and successful literature searches and are utilizing them accordingly. An important thing to note is that you are lacking in-text references in a few sections, especially “Biopsy Methods”, and in your lists of advantages and disadvantages. Make sure to add these to avoid academic misconduct to allow your reader to do further reading if they wish. &lt;br /&gt;
&lt;br /&gt;
Overall, this is a really good page so far. You have demonstrated great teamwork and strong efforts to make this page standout. I suggest you consistently edit your work, add more visual aids, and condense your information where possible to gain the mark you deserve. Fantastic work! &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===5===&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
There is no introduction, not having an introduction would mean there is no overview of what this page would be about and what it will discuss in detail. If an introduction could be uploaded maybe consider an image or a short video that would be able to sum the introduction up. This must be done instead of just going straight into the “History “.It would make your page more appealing and professional if you followed through with an introduction. Other than that, I appreciate the detail that went through. There is great amount of reference at the end of each section which is great, however there is no in- text referencing in some sections like procedure of “Genetic Techniques”. Having in-text referencing will allow the audience to know exactly where the information was read from and for the interest of the audience can read that specific paper in detail. There is a great amount of information in almost every section with great detail however, consider more subheadings to make the sections easier to read and allows the audience to navigate the page effortlessly. This was the case for ““Polar Body Analysis” section”. The information here is quite dense therefore you could split or organize information into more subheadings. &lt;br /&gt;
&lt;br /&gt;
I also noticed that there is not enough information in historic findings; this is an important key point that needs to be addressed. Present some online research, add some images, some in text referencing and maybe a table or timeline, this should help shape the historic findings section. Finding information on historic findings might be a little challenging. A suggestion I can make is to search for old articles in PubMed (by adjusting the year). Review articles that summarise historic findings related to Prenatal Genetic Diagnosis may also be helpful. You also need to find information on current research as well. Other subheadings that are either incomplete or missing are “Ethics “and “Future/Current Research”. This can to be done in the same manner as the historic findings. The tables displayed in the other sections are great as they simplify information and is an effective way for students to study so well done! Keep in mind this is meant to be informative and easy to comprehend, so try and find that balance. Thus, consider some more images, diagrams, graphs and tables  in each section, to make it more inviting and not overwhelming with just content. Captions should be added on the page for some of the images to state what the images are showing.&lt;br /&gt;
&lt;br /&gt;
Try and look for a youtube video that can help summaries the content on your page. If possible try adding hand drawn images too. A glossary list should be incorporated in a separate subheading to define some of the technical words so that viewers can fully grasp the information.&lt;br /&gt;
&lt;br /&gt;
Having said all those down side points, this page is coming along nicely with many positive aspects:&lt;br /&gt;
&lt;br /&gt;
•	Great amount of references at the end&lt;br /&gt;
&lt;br /&gt;
•	Concise in text citation except in some paragraphs&lt;br /&gt;
&lt;br /&gt;
•	  Good use of images&lt;br /&gt;
&lt;br /&gt;
•	The use of dot points in different sections to format the info is very useful and provides clarity&lt;br /&gt;
&lt;br /&gt;
•	Great table of advantages and disadvantage in section “Biopsy Methods” &lt;br /&gt;
&lt;br /&gt;
•	The key points have been clearly described&lt;br /&gt;
&lt;br /&gt;
•	Having Future/Current Research”  sub heading which is great&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Overall, I can appreciate the difficulty of this topic.  However if you work on the subheading within each section and add some images, videos and diagrams  as well as some in text referencing I think that should make a significant difference by making this page more inviting, easier to navigate and also appear greatly organized. GOOD LUCK&lt;br /&gt;
&lt;br /&gt;
===6===&lt;br /&gt;
This project page is very well done. Clearly, you have done huge amount of research on this topic. And all sections of the page are well balanced.&lt;br /&gt;
&lt;br /&gt;
I appreciate that you include the advantages and disadvantages of each diagnostic methods, which not only indicates your thorough understanding of the topic, but also make it easier for readers to compare each methods.&lt;br /&gt;
&lt;br /&gt;
Images and tables are well chosen in your page. It would be great if you can add more visual aids in some sections because there are large amount of texts in some section.&lt;br /&gt;
&lt;br /&gt;
===7===&lt;br /&gt;
&lt;br /&gt;
Your project page is coming along very well so far. You research into the subject seems very extensive and sufficient. You have many citations which have been cited properly. Your long list of references and the many in text citations are evident of the effort and depth that you have gone into your research. Furthermore, you have added a heading on future and current research which further shows the relevance and recent nature of your research beyond the teaching aspect. You have chosen relevant headings and figures so far, explained the key points well and taught the content at a peer level showing a good understanding of the topic. Its great that you have also chosen to include the laws and legal status to show how the topic is relevant to society and how it is being translated from research to the clinic. &lt;br /&gt;
&lt;br /&gt;
While the images you have included so far are engaging and relevant I feel that much more is needed since your research into the topic is very widespread. More images, diagrams and graphs (maybe a graph on the rate of genetic testing use can be helpful) would help to break up the text, balance the page better and make the page more engaging. Also, try to refer to your files in text as well so they may complement your explanations and enhance understanding of the topic. Including your own innovative drawings and searching for relevant videos would also help to teach key points better. When adding your files try to maintain the same formatting, some of your images are added as thumbnails while others are not. &lt;br /&gt;
&lt;br /&gt;
Additionally, you are still lacking an introduction. You have included a heading for it so I assume you will get to it, but make sure its included as its very helpful in orientating your reader and providing some background information for those without a significant scientific background. You should also consider adding a timeline to the section on history, it is more engaging to your viewer and easier to read. I would also recommend adding some more tables, they are visually appealing and also help to break up the text. I suggest you add a table of the diseases tested for, with a brief description of the disease, the specific genetic test used to detect it and at what stage its used. Animal models can also be included to show research into the topic beyond the teaching activities. Finally, make sure you reread over your work and edit your spelling and grammar in some areas. &lt;br /&gt;
&lt;br /&gt;
Good effort overall, well done!&lt;br /&gt;
&lt;br /&gt;
===8===&lt;br /&gt;
&lt;br /&gt;
You have done a great job for your project! As we can see from the amount of your references, huge amount of research must have been done. The key points relating to the topic are clearly described. The page is organized very well and the use of expandable table keeps the page neat. The images and tables used are highly relative to your topic. I would recommend that:&lt;br /&gt;
&lt;br /&gt;
1.	Instead of using the acronym, the use of full form ‘Artificial Reproductive Technologies’ for the topic name maybe better. &lt;br /&gt;
&lt;br /&gt;
2.	The introductory part is missing. It gives readers an overview of the page and helps readers without background knowledge understanding the topic easier.&lt;br /&gt;
&lt;br /&gt;
3.	The layout for the Biopsy Methods part maybe reconsidered. More spacing between three different methods will make the page easier to read. And also, the background color for the table may be lighter. Since the table is a summary of the three methods, I will suggest moving it to the end of the three methods.&lt;br /&gt;
&lt;br /&gt;
4.	A hand-drawn image somewhere on the page or a video can be added.&lt;br /&gt;
&lt;br /&gt;
5.	For the legal status, it would be nicer if you can classify these countries according to whether they are permit or prohibit.&lt;br /&gt;
&lt;br /&gt;
Overall, you have made a great page. Thanks for your effort.&lt;br /&gt;
&lt;br /&gt;
===9===&lt;br /&gt;
&lt;br /&gt;
This page has an impressive amount of content, this shows that you guys have done amazing research and deducing those which are relevant for this chosen topic.  As your page is very content heavy, visual aids (detailed diagrams, videos, tables and flowcharts) can be a great way to lighten the content and keep the audience interested. Remember to add a hand drawn diagram!  The heading used were very appropriate for the topic, but the overuse of subheadings makes it harder for the audience to understand.  I would suggest to condense some of the subheadings as I think some are not necessary (Laws and Legal Status - it is fine just having the countries in bolding titles) I suggest having them in a table which will look a lot neater.  In the subheading, it is clear that there is a lot of advantages and disadvantage; I suggest to have them in table format, making it easier to read for audiences.  But it is also good to see that you have made use of bullet points.&lt;br /&gt;
&lt;br /&gt;
Adding a glossary at the bottom will be very beneficial for the audience as there are a few terms that are not explained (IMSI, IVF and FISH etc).  There are still a few headings and sub which have not been touched on; “Utilisation of Diseased Cell Lines” and “Ethics” I am certain with more research, no doubt the content of these will be great! &lt;br /&gt;
&lt;br /&gt;
Your reference list is extremely long which is good!  Showing you have done numerous and numerous of literature searches and put them to good use.  Just to remind you that it is important to have in-site referencing in the body of the page.&lt;br /&gt;
&lt;br /&gt;
Overall, the page was a delight to read! All the content seem to be integrated nicely which shows great teamwork.  I am certain after condensing some information and including visual aids, your page will be awesome!&lt;br /&gt;
&lt;br /&gt;
===10===&lt;br /&gt;
&lt;br /&gt;
This is a very well organised and detailed analysis of the topic. An impressive amount of research has gone into delivering such an informative page.  &lt;br /&gt;
&lt;br /&gt;
You have the appropriate sub-headings which make it easy to understand the information, however there may be a few too many. See if you can try and merge a few sub- headings together. I particularly liked the breakdown of each biopsy method into the three minor headings of description, procedure and advantages and disadvantages. This is a good way to approach such a content heavy topic. &lt;br /&gt;
&lt;br /&gt;
It would be a good idea to include more images and videos as there is a lot of text on your page. I could not see an original image on your page, so it would be good to hand draw an exisitng image or another image. You can also include more tables to break the monotonous style of reading paragraphs of text, especially when describing the advantages and disadvantages of the genetic techniques.  &lt;br /&gt;
&lt;br /&gt;
The laws and legal status section is a bit unnecessary as it is not an important part of this topic. A simple table would be good to summarise the current legal status for each country without having to write a paragraph for each. &lt;br /&gt;
&lt;br /&gt;
I liked that you ended of by discussing current and future research, which not many groups have done. The last sub sub-heading for this section, &amp;quot;Utilisaiton of Diseased Cell Lines&amp;quot; does not have any text underneath it. &lt;br /&gt;
&lt;br /&gt;
It would also be helpful for the readers if a glossary is included at the end of the page as there a few terms that are difficult to understand. &lt;br /&gt;
&lt;br /&gt;
Overall, this is a very impressive page with an abundance of information. The topic has been covered comprehensively which is a mark of good teamwork as a lot of research has been done to cover such an expansive topic. Great job!&lt;br /&gt;
&lt;br /&gt;
===7===&lt;br /&gt;
&lt;br /&gt;
The Project is structured really well, with multiple headings and subheadings. This report contains a lot of citations and references which help with the clarity of the report. It was easy to follow because of the different headings included. Different sections either had tables, bullet point lists, diagrams or images that helped create an understanding of the information. It is obvious that a lot of research was done for this topic. Diagrams, tables, microscopic images, graphs, in vitro analysis, lists, collapsed tables are all a great tool to use besides just information.&lt;br /&gt;
&lt;br /&gt;
The first half of the report is just information, until the diagrams are seen, possibly separate into subheadings, or bullet points as it may be unclear as there is just loads of information by themselves. The layout affects the clarity also, as it is a heading with sub information, possibly adjust the lining of the paragraphs so the headings and subheadings stand out. The citations and references are done extensively.&lt;br /&gt;
&lt;br /&gt;
The introduction and ethics headings are left empty which obviously need to be filled with information, a glossary section may prove helpful if added for the reader’s benefits, and even a further reading section could help. Overall this report is good however the clarity and structure should be assessed in order to make this a better report.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===8===&lt;br /&gt;
The topic for this page is clearly broad and there is a lot of information that needs to be addressed, it can be inferred that a lot of concise research and time has been spent on this page. The students also do a good job to reference in text correctly and most of their images have correct copyright information.&lt;br /&gt;
&lt;br /&gt;
There is a LOT of text used on this page – more attention needs to be payed to reducing and compressing the sections of text within the page – try adding different formatting styles to the way the text sits on the page, or putting some of the information into tables or possibly using a video where applicable to simplify the explanation of an issue. &lt;br /&gt;
I would also recommend trying to keep consistent formatting/presentation of all images throughout the page. Some are in thumbnails, others don’t have descriptions etc.. Keeping consistency with the formatting will make the page look much clearer and cohesiveness. &lt;br /&gt;
&lt;br /&gt;
The whole page will largely benefit from a greater increase in the number of media files used, particularly in the top section of the page. Readers want to be enticed into the page so having many images and media files at the start of the page will go a long way in keeping readers interested and encouraging them to keep working through the page. &lt;br /&gt;
&lt;br /&gt;
The order of the text is also somewhat complicated and scattered – try to simplify the text where possible and link all subheadings together, making the page more cohesive as a whole. Irrelevant bits of information should be deleted and reduced as much as possible.&lt;br /&gt;
The page is good and on its way to being an informative and clear page for students.&lt;br /&gt;
&lt;br /&gt;
==9==&lt;br /&gt;
Fantastic job guys, this one hard to pick on.&lt;br /&gt;
Layout is great, flows, logical topics, easy to read, nicely broken up with informative or interesting images. Just smashing. References appear to all be solid.&lt;br /&gt;
So what can I suggest? You could try making up a table for the advantages and diss advantages so it’s easy to compare each tech. The PCR Cycle copies table is just a list of exponential growth and can go.&lt;br /&gt;
Hyperlink some of your key words to the glossary or other pages so people can get background or further reading on topics involved. &lt;br /&gt;
Change the heading to spell out Assisted Repro… etc. so that its stated before you abbreviate.  Collect up the info to make your intro and so far you have the best project of the group. Pretty flawless guys.&lt;br /&gt;
&lt;br /&gt;
==10==&lt;br /&gt;
To start with, just looking at your table of contents alone, it looks extremely thorough. Your choice of headings and choice of subheadings are very extensive, and your subheadings and sub-subheadings are very diverse, making it easy to spot and read when specific information is required when reading your page. &lt;br /&gt;
&amp;lt;b&amp;gt; Pros &amp;lt;/b&amp;gt;&lt;br /&gt;
* Your information and research is extremely thorough, exceeding the basic requirement of the assessment, which is really good and informative&lt;br /&gt;
* Nice summary in “biopsy method”, especially in a section with a lot of writing in it&lt;br /&gt;
&amp;lt;b&amp;gt; Cons &amp;lt;/b&amp;gt;&lt;br /&gt;
* A short explanation in the introduction would help, and if possible, give it a video, to capture your audience at first glance.&lt;br /&gt;
* In your genetic techniques, “PCR” “Advantages and Disadvantages” would look better if it was placed in a table. For long lists and dot points, tabulation would make it look more organized and readable&lt;br /&gt;
* Watch out with your headings, sub headings, sub-sub headings, and sub-sub-sub headings, in “genetic techniques” they look all meshed together, its hard to distinguish, which sub-sub-sub heading and sub-sub headings belong to which section; it can look a bit messy and all over the place.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

[[User:Z5088434|Z5088434]]([[User talk:Z5088434|talk]] Would the part you added in indication rather be part of the introduction since it pretty much sums up what the page is about? Maybe go into when PGD and PGS are applied? as for the multiple instances citations: first in text citation has to be like this: &amp;lt;ref name=&amp;quot;PMID...&amp;quot;&amp;gt;&amp;lt;pubmed&amp;gt;...&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; and the following ones are like this: &amp;lt;ref name=&amp;quot;PMID...&amp;quot;/&amp;gt; (just check for the code in the edit mode, can't figure out how to just show the code without it actually configuring it...)&lt;br /&gt;

==Cell Extraction Methods==&lt;br /&gt;
Polar bodies: Applying PGD to polar bodies is desired as it can be used before conception. Since genetic testing can be conducted within twenty four hours this makes it possible for the transfer to the mother at the blastomere stage. However this method isn’t commonly used due to the fact that all oocytes must be tested including those that may not progress to mature and only genetic material from the female can be retrieved &amp;lt;ref name=&amp;quot;Coward, K. &amp;amp; Wells, D. (2013). Textbook of Clinical Embryology New York: Cambridge University Press.&amp;quot;&amp;gt;Coward, K. &amp;amp; Wells, D. (2013). Textbook of Clinical Embryology New York: Cambridge University Press.&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Cleavage stage: This involves the biopsy of the blastomere (6 to 10 cells) &amp;lt;ref name=&amp;quot;PMID11325751&amp;quot;&amp;gt;&amp;lt;pubmed&amp;gt;11325751&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. It is advantageous to work on blastomeres as they are totipotent, meaning they can give rise to a diverse range of cells. Studies have also shown that there is no increase in congenital abnormality rates caused by the removal of blastomere cells &amp;lt;ref name=&amp;quot;Coward, K. &amp;amp; Wells, D. (2013). Textbook of Clinical Embryology New York: Cambridge University Press.&amp;quot;/&amp;gt;. Contrarily, studies have shown that the standard removal of two blastomeres at one time will decrease its potential to develop into a blastocyst &amp;lt;ref name=&amp;quot;PMID19773223&amp;quot;&amp;gt;&amp;lt;pubmed&amp;gt;19773223&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Along with the fragility of the cells at this stage, highly skilled embryologists are required to minimise poorly performed biopsies which could subsequently lead to impaired growth and a decrease in implantation. Unlike polar bodies both maternal and paternal genes can be tested if PGD is performed at this stage. &amp;lt;ref name=&amp;quot;Coward, K. &amp;amp; Wells, D. (2013). Textbook of Clinical Embryology New York: Cambridge University Press.&amp;quot;/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Blastocyst: Performing PGD at this stage is the least common since many patients do not produce embryos healthy enough to reach this stage. Multiple cells can be extracted at this stage for biopsy producing more accurate results. This is possible due to the fact that biopsies have little effect on the development of the embryo. Genetic tests must also be conducted rapidly since implantation is optimal at this stage &amp;lt;ref name=&amp;quot;Coward, K. &amp;amp; Wells, D. (2013). Textbook of Clinical Embryology New York: Cambridge University Press.&amp;quot;/&amp;gt;&lt;br /&gt;

&lt;br /&gt;
* Estimated to cause one third of all defects &lt;br /&gt;
* Abnormalities in chromosomes are usually due to structural or numerical changes. These can occur in sex chromosomes or autosomes. &lt;br /&gt;
** Numerical abnormalities are a result of nondisjunction. Nondisjunction is when a pair or chromatids fail to disjoin during meiosis or mitosis. E.g. Turners Syndrome, Trisomy 21 (Down syndrome) and Trisomy 18 (Edward’s Syndrome). &lt;br /&gt;
** Structural abnormalities are usually a result of chromosome breakage followed by reconstitution in an abnormal combination. There are different types of structural abnormalities including translocation and deletion of chromosomes &lt;br /&gt;
* Mutations cause 8% of birth defects. It involves the loss or change in the function of a gene which is permanent and heritable.&lt;br /&gt;

&lt;br /&gt;
* two categories of preimplantation genetic testing: PGS (-Screening) &amp;amp; PGD (-Diagnosis); different indications&lt;br /&gt;
** PGS: IVF procedure due to infertility without known genetic abnormalities in patients&lt;br /&gt;
** PGD: IVF procedure &amp;amp; genetic testing chosen because of known genetic abnormalities in patients&lt;br /&gt;
* Methods: &lt;br /&gt;
** Polar body analysis: first and second polar body are extruded following completion of meiosis I and meiosis II&lt;br /&gt;
*** Advantages: does not harm embryo, can be used to detect 146 Mendelian disorders, reported 99% accuracy &lt;br /&gt;
*** Disadvantages: paternal genetic contribution is not investigated --&amp;gt; additional procedures &lt;br /&gt;
** Blastomere biopsy: embryo is 3 day old, 6-8 cells stage, most commonly used, hole is made in zona pellucida to retrieve one cell&lt;br /&gt;
*** Disadvantages: 10% pregnancy reduction,&amp;quot;mosaicism of the blastomeres may not reflect the chromosomal complement of the developing embryo&amp;quot;&lt;br /&gt;
** Trophectoderm biopsy: 5-6 day old blastocyst, 5-7 cells are removed&lt;br /&gt;
*** Advantage: no cells removed from embryo&lt;br /&gt;
*** Disadvantage: additional procedures may be necessary because of later stage of developing embryo (cryopreservation, implantation at later IVF-cycle)&lt;br /&gt;

===Maternal, Fetal &amp;amp; Neonatal physiology: a Clinical perspective :Prenatal Diagnosis and Maternal, Fetal &amp;amp; Neonatal physiology: a Clinical perspective: Prenatal Diagnosis:=== &lt;br /&gt;
&lt;br /&gt;
Prenatal diagnosis is the screening process that tests an early fetus for overall growth, complications of pregnancy, birth defects and chromosomal or genetic abnormalities within the first 2 trimesters. It aims to provide the parents with as information as possible to help them make an informed decision about the infants quality of life. In 90-95% of the cases negative outcomes occur; confirming the healthy state of the fetus, should a genetic abnormality be present, it provides the parents with the opportunity to  investigate further with other tests, and possible fetal therapeutic treatments available as well  plan and prepare for the disabled infant  or to terminate the pregnancy. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
*Indicators for prenatal screening/ high risk factors include:&lt;br /&gt;
**maternal ages &amp;gt; 35 years&lt;br /&gt;
**paternal ages &amp;gt; 50-55&lt;br /&gt;
**history of 2+ miscarriages&lt;br /&gt;
**previous pregnancy or family history of a preexisting genetic or chromosomal disorder&lt;br /&gt;
**suspected carriers of genetic disorders&lt;br /&gt;
** maternal disease/condition present (high BP, diabetes)&lt;br /&gt;
**abnormal ultrasound or serum test results within the first 2 trimesters&lt;br /&gt;
**family history of neural tube or other birth defects &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
*Ultrasonography:&lt;br /&gt;
**high frequency sound waves are used to generate a image of the fetus &lt;br /&gt;
**relatively non-invasion; its conducted transabdominally or transvaginally ( producing a higher resolution image) &lt;br /&gt;
**It reveals the presence/absence of congenital abnormalities, characteristics of fetal growth and development, uterine development status; amount of **amniotic fluid, placental position, umbilical blood flow and the presence of multiple gestation. &lt;br /&gt;
**(if abnormalities are detected further testing is recommended)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
*Amniotic Fluid Analysis/:&lt;br /&gt;
**samples are obtained through amniocentesis &lt;br /&gt;
**the amniotic fluid is analyzed for its biochemical composition &lt;br /&gt;
**earlier in the pregnancy it can be examined for sex determination and to diagnose genetic or chromosomal disorders present. &lt;br /&gt;
**Later into the pregnancy it provides an indication of fetal maturity and well being&lt;br /&gt;
**Feta; cells recovered from the amniotic fluid can be cultured for specific karyotypes, to test for Chromosomal Abnormalities, and analysed for Alpha- fetoprotein (AFP) a biochemical marker of metabolic disorders and neural tube defects as well as other abnormalities.  &lt;br /&gt;
**Amniocentesis- occurs usually between weeks 14-20 as amniotic fluid has reached the optimal volume (150-250mls) allowing 20-30mls to be removed with a relatively low risk or fetal or maternal complication, and in time for a 2nd trimester abortion.&lt;br /&gt;
**early amniocentesis ( before week 13) increase the risk of fetal loss, leakage of essential amniotic  fluid and talipes equinovarus.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
*Chronic Villus Sampling  (CVS):&lt;br /&gt;
**occurs  roughly 10-13 weeks after last menstrual cycle, ensuing a sufficiently developed chorionic villi but before the chorion laeve forms the definitive placenta. &lt;br /&gt;
**ultrasounds is used to locate the gestational sac and implantation then a transcervial or transabdominal approach is used to aspirate living tropoblast tissue.&lt;br /&gt;
**sample is analyzed for chromosomal abnormalities or with enzyme assay. &lt;br /&gt;
**advantages: earlier diagnosis , decreased waiting period&lt;br /&gt;
**disadvantages: risk of spontaneous abortion, bacterial infection, bleeding, leakage of amniotic fluid, inability to diagnose neural tube defects this early, early cleavage (before wk 10) is associated with increased risk of limb defects (due to insufficiently developed chronic villi) &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
*Umbilical Blood Sampling:&lt;br /&gt;
**can occur as early as 16 weeks &lt;br /&gt;
**using the umbilical cord to obtain fetal blood samples - with real time ultrasound &lt;br /&gt;
**used to diagnose inherited blood disorders, to detect congenital infections, to assess fetal anemia and in treatments such as blood transfusions. &lt;br /&gt;
**disadvantages: risks of infection, preterm labor, thrombosis, bleeding &amp;amp; transient fetal arrhythmia &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
*Fluroscent in Situ Hybridisation (FISH)&lt;br /&gt;
**rapidly detects (within 24 hours of testing )  the presence of Trisomies 21, 13 and 8 and alterations in sex chromosomes in uncultured cells. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
*early diagnosis allows the opportunity for intervention with fetal therapies: &lt;br /&gt;
**surgical intervention urinary tract obstruction ; aiming to reduce prenatal renal damage&lt;br /&gt;
**fetal transfusions ( feta anemia &lt;br /&gt;
**fetal medical treatmetn ( fetal cardiac arrhythmias,impaired thyroid function etc.) treatment occurs   usually through the mother &lt;br /&gt;
** infusions for hematologic conditions &lt;br /&gt;
**stem cell transplantation&lt;br /&gt;
**gene therapy  &lt;br /&gt;
**pharmocolic interventions &lt;br /&gt;

&lt;br /&gt;
Heat stress has previously seen a decrease in fertility in dairy cows, whilst similarly, pregnancy rates in women are recorded to be lowest during the summer season, paving way for the postulation that fertilization may be disrupted due to elevated temperatures. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
3 different experiments were performed to determine the underlying mechanism causing the disruption to fertilization due to increase in temperature. Oocytes and Spermatozoa were exposed to physiological temperatures that mirrored those of mammalian organisms. Oocytes were fertilized at 38.5-41ºC with either no-pre-incubated sperm or 38.5 / 41ºC incubated sperm, to investigate the effected on sperm plasma membrane, viability, and penetration, polyspermy, subsequent development of zygote, and embryonic competence. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
The results showed that at elevated temperatures, percentage of motile sperm were reduced, along with altered transcription due to oxidative stress, resulting in an increase in polyspermy. In addition, the zona pellucida of zygotes was sensitive to pronase digestion during heat stress, and exhibited decreased transcription of gene UCHL1, which played the role of preventing polyspermy. Rates of cell cleave and blastocysts formation were also seen to have reduced. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
Because of the results shown, this study reports that the increase in polyspermy is the most likely cause of the reduced blastocyst formation due to the reduced capability of zygotes at elevated temperatures to develop to the next stage. (Sakatani et all, 2014)&lt;br /&gt;

&lt;br /&gt;
Cyclophosphamide is an alkylating agent most commonly used to treat cancers with other chemotherapy agents. It’s used to quickly control cancerous diseases but is highly toxic. Sperm banking in those prior to cancer treatment have seen to have more effective Intracytoplasmic Sperm Injection in In Vitro Fertilization compared to those performing IVF/ICSI after their first dose of chemotherapy. This study tests whether there is correlation between the agent, Cyclophosphamide, and the reduced preimplantation embryo development, birth rate, and genetic integrity of embryos after embryo transfer. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Untreated sperm of adult male B6D2 mice were first collected. They were then administered cyclophosphamide after seven days, and were sacrificed to obtain the treated sperm. Oocytes were collected after controlled ovarian stimulation. Half the oocytes from each female were exposed with Cyclophosphamide exposed sperm and untreated sperm from the same male mice. Embryos were monitored in vitro for 2 days and were then collected for exome sequencing. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Results showed that the average percentage of oocyte survival was 94.8%, whereas for embryos treated with Cyclophosphamide, percentage of survival was significantly lowered to 49%. Birth rates after embryo transfer showed no difference between the two groups but Cyclophosphamide-treated group had lower litter size (0.8 vs 3.8) and pups per embryo transferred (2.7% vs. 14%). (Johnson et all, 2015)&lt;br /&gt;
This study argues that Cyclophosphamide exposed sperm decreased development in embryo, resulting in lowered numbers of offspring and lower number of offspring survival. Further investigation is needed in order to know the reason and mechanism behind Cyclophosphamide’s influence on male sperm and fertilization. (Johnson et all, 2015)&lt;br /&gt;

===Female Infertility : Diagnosis===&lt;br /&gt;
====MR imaging of disorders associated with female infertility: use in diagnosis, treatment, and management.&amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;14615553&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;====&lt;br /&gt;
&lt;br /&gt;
MR imaging has extended its use to evaluating and diagnosing disorders related to female infertility, including ovulatory, fallopian tube, and uterine disorders, and also pelvic enometiosis. It is used in a variety of clinical settings by providing a clear vizualization of the pelvic region and is now useful in conjunction with other diagnostic techniques like laparoscopy, hysteroscopy, and hysterosalpinogography.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;i&amp;gt; PMID 14615553 &amp;lt;/i&amp;gt;&lt;br /&gt;
&lt;br /&gt;
====Comparison of diagnostic accuracy of laparoscopy, hysteroscopy, and hysterosalpingography in evaluation of female infertility. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;6232154 &amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;====&lt;br /&gt;
In a group of 77 women evaluated, Laparoscopy confirmed 84% evidence of tubal disease and hysteroscopy confirmed 69% radiographic evidence of intrauterine abnormalities. IN contrast HS gave a false-positive rate of 16% and 31% respectively. Data suggests that laparoscopy is best detecting previously unsuspected tubal disease, and hysteroscopy with information of managing abnormalities. But for optimum evaluation, a combined approach of all three procedures is best.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;i&amp;gt; PMID 6232154 &amp;lt;/i&amp;gt;&lt;br /&gt;
&lt;br /&gt;
====Diagnosis and Management of Female Infertility. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;14519712&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;====&lt;br /&gt;
Earlier assessment is best in women who have history of oligomenorrhea/amenorrhea, with key objective of assessment and diagnosis to rule out azoospermia, anovulation, or tubal obstruction.&lt;br /&gt;
In order to do so an assesment of ovulatory function, uterine cavity, and tubal patency by HSG/laparoscopyis needed.&lt;br /&gt;
Assessments like post coital tests, endometrial biopsies, and basal bdy temperature records are no longer a routine investigation.&lt;br /&gt;

===Group 1===&lt;br /&gt;
The topic of three person’s embryo was outlined and described well, with good choice of headings, separating the different key points and areas that you’ve discussed on your page. It’s evident you’ve done extensive research on your topic, and especially going through your reference list, all your research data were extremely recent, which is excellent!&lt;br /&gt;
&lt;br /&gt;
&amp;lt;b&amp;gt;Pros&amp;lt;/b&amp;gt;&lt;br /&gt;
*I loved that you put an introductory video in the beginning, which is a personal account rather than a scientific stimulation video, giving it a more personal touch on the page, and highlighting the importance of this breakthrough in 3 person’s embryos. &lt;br /&gt;
*Because your topic isn’t a disease but a medical breakthrough, your own chosen headings were fantastic and on point, giving a well-rounded and detailed wiki page&lt;br /&gt;
*The format of the page is also really good. Its good to use more subheadings than main headings, and you’ve formatted the page really well&lt;br /&gt;
*You’ve used very current research, making your page much more credible and updated with the newest information&lt;br /&gt;
*The “further reading” section was really good, it extended beyond the normal “teaching” topics, giving the reader a better insight of the topic, if they choose to.&lt;br /&gt;
&amp;lt;b&amp;gt;Cons&amp;lt;/b&amp;gt;&lt;br /&gt;
*The introduction looked a bit short. A more detailed explanation will make the reader understand a lot more on how it works and how the page looks, without the reader having to watch the video if they choose to just skim the page.&lt;br /&gt;
*Your heading and subheading of “History” and “Timeline” could’ve been merged into one, as that was  your only subheading of that heading,it would’ve looked more readable that way&lt;br /&gt;
*Timeline information could be extended more, in terms of date (if found) and details on what occurred on that date&lt;br /&gt;
*The heading of “Benefits” also needs to be extended VERY much more, two subheadings an 3 sentences under one, with a link under the other, does not explain any benefits at all&lt;br /&gt;
*Pictures in “Technical Progression” could be skewed to the right, so the words all flow, with the HELP of the diagram, instead of the focus being on the photos&lt;br /&gt;
*Current research also needs to be expanded more. PMID wouldn’t be needed either if you had expanded the current research, and referenced it in your reference list; section looks a bit messy with bullet points starting with hyperlink&lt;br /&gt;
*“Technical Progression” needs to be greatly edited and to have information added&lt;br /&gt;
*“Ethics” also needs to be expanded, and again, don’t lead with PMID&lt;br /&gt;
*“Glossary” is not really needed if you explain those terms in each words occurrence instead of at the end, but this is a minute point&lt;br /&gt;
&lt;br /&gt;
===Group 2===&lt;br /&gt;
The topic of OHSS was outlined very well, with very good choice of headings, separating the different key points and areas that you’ve discussed on your page. It’s evident you’ve done extensive research on your topic, and all your information is very concise and very readable. You’ve also extended your topic beyond the general symptoms, diagnosis, causes etc like “animal models” “effect on the newborn”, it is very extensive!&lt;br /&gt;
&amp;lt;b&amp;gt;Pros&amp;lt;/b&amp;gt;&lt;br /&gt;
*Extensive research evident, a lot of information is provided&lt;br /&gt;
*Introduction is short and concise, but also extremely informative, highlighting the aim of the page as well!&lt;br /&gt;
*Statistics of the disease is also given, numerical data is always good&lt;br /&gt;
*Good use of a table in “Symptoms”, making it very readable and engaging&lt;br /&gt;
*The presence and position of the drawing in “Pathophysiology” is prenominal, you’ve gone out of your way to draw a diagram to illustrate the topic&lt;br /&gt;
*Good use of bullet points in “Treatment”, very concise and readable and there isn’t a jumble of words&lt;br /&gt;
&amp;lt;b&amp;gt;Cons&amp;lt;/b&amp;gt;&lt;br /&gt;
*A photo or video in your introduction could be used to illustrate what the topic is better&lt;br /&gt;
*There’s a lot of technical jargon already in your introduction, words like neoangiogenesis and iatrogenic. Readers who come to your page may not necessarily understand those words. These words can be defined in your glossary, but readers read in logical flow, they won’t scroll all the way to the bottom of your page because they didn’t understand the word to find the meaning then come back to the introduction to continue. These words don’t have to be replaced, but an explanation might ease your cause&lt;br /&gt;
*A graph or table or pie chart representing epidemiology will make the heading more informative&lt;br /&gt;
*Photos showing symptoms will substantially help, especially when they’re separated into mild, moderate, and sever.&lt;br /&gt;
*Diagnosis needs to be expanded more. The bold type words should be made into subheadings so you can expand on each more, defining how and why they are performed&lt;br /&gt;
*Headings of “effect on the newborn” and “animal models” need to be completed&lt;br /&gt;
*You have a lot of information on your page but only a few are referenced, a lot more in text referencing and references are needed for the amount of information you have&lt;br /&gt;
&lt;br /&gt;
===Group 4===&lt;br /&gt;
*The structure of your page is extremely excellent! It flows very well, all headings and subheadings were chosen really well, the use of tables and diagrams are incredible!&lt;br /&gt;
*The heading of “Background information” is VERY extensive, and also concise! The diagram placement is also excellent, and their use is also extremely excellent&lt;br /&gt;
*The use of the video to explain the cause of infertility is absolutely amazing, it makes your page look good, keeps your explanation short, concise, and readable, and it also engages the audience&lt;br /&gt;
*Each subheading under “Causes” is also very well outlined and explained, there is a lot of information there, and it is sure whatever information the reader may need would be found on your page as it has covered and explained a lot&lt;br /&gt;
Overall, all I have for your group are good comments, as I couldn’t think of anything else that you will might need to add or change on it at all! Your information extends beyond what is expected, but also extensive, concise, and, most importantly, extremely readable and engaging! GOOD WORK!&lt;br /&gt;
&lt;br /&gt;
===Group 5===&lt;br /&gt;
Your information extends beyond what is expected, but also extensive and readable and engaging. The page is formatted really well.&lt;br /&gt;
&amp;lt;b&amp;gt;Pros&amp;lt;/b&amp;gt;&lt;br /&gt;
*The structure of your page is really good. It flows well, all headings and subheadings were chosen really well, the use of diagrams keeps it engaging&lt;br /&gt;
*Each subheading is chosen and highlighted well&lt;br /&gt;
*A very extensive reference list, making it evident that you have researched your topic thoroughly!&lt;br /&gt;
&amp;lt;b&amp;gt;Cons&amp;lt;/b&amp;gt;&lt;br /&gt;
*Use of diagrams and photos in the introductory parts of your page will make your page much more engaging&lt;br /&gt;
*You may have extensive information but its not too concise. At a glance of your page, all you see are huge jumbles of words, and if you read the information, it needs to be summarized a lot more&lt;br /&gt;
*Photos in Surgery and Fertility Drugs can make it more interesting and it can help you explain them more on what it looks like and whats involved using a single image&lt;br /&gt;
*The use of the video explanation is also very good, but keep in mind that this page isn’t really aimed for people with minimal knowledge on cancer cells, but those trying to extend their knowledge, so they would already know about cancer cells. (Less is more)&lt;br /&gt;
*Use a table in Chemotherapy Drugs can make long lists look much better&lt;br /&gt;
*Reserve subheadings for your bold keywords underneath “Fertility preservation in women” instead of just bold type, it will look much more organized&lt;br /&gt;
&lt;br /&gt;
===Group 6===&lt;br /&gt;
To start with, just looking at your table of contents alone, it looks extremely thorough. Your choice of headings and choice of subheadings are very extensive, and your subheadings and sub-subheadings are very diverse, making it easy to spot and read when specific information is required when reading your page. &lt;br /&gt;
&amp;lt;b&amp;gt; Pros &amp;lt;/b&amp;gt;&lt;br /&gt;
* Your information and research is extremely thorough, exceeding the basic requirement of the assessment, which is really good and informative&lt;br /&gt;
* Nice summary in “biopsy method”, especially in a section with a lot of writing in it&lt;br /&gt;
&amp;lt;b&amp;gt; Cons &amp;lt;/b&amp;gt;&lt;br /&gt;
* A short explanation in the introduction would help, and if possible, give it a video, to capture your audience at first glance.&lt;br /&gt;
* In your genetic techniques, “PCR” “Advantages and Disadvantages” would look better if it was placed in a table. For long lists and dot points, tabulation would make it look more organized and readable&lt;br /&gt;
* Watch out with your headings, sub headings, sub-sub headings, and sub-sub-sub headings, in “genetic techniques” they look all meshed together, its hard to distinguish, which sub-sub-sub heading and sub-sub headings belong to which section; it can look a bit messy and all over the place.&lt;br /&gt;
&lt;br /&gt;

--[[User:Z8600021|Mark Hill]] ([[User talk:Z8600021|talk]]) 11:23, 25 September 2015 (AEST) OK, there is so much more that should be on your project page by now. That currently consists of all text, no media, histology, graphics, tables etc. Furthermore no discussion of animal models used in research for this topic. This project page is not ready for peer review.&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
Hi everyone,&lt;br /&gt;
the page is coming together well. &lt;br /&gt;
only thing is while we write up our parts can we focus on all using in text referencing so that we are consistent and can just have a single reference list at the bottom.&lt;br /&gt;
I found out how to use the same reference again and only have it associated with one in text number, so if you are using the same reference and would like me to show you how to do this let me know :)&lt;br /&gt;

 &lt;br /&gt;
I have added some of the references + citations but not yet finished as this is only the draft and I might delete some of the parts so there is no point adding the citations/ text referencing now.

===[Oncofertility and breast cancer: Where have we come from, where are we going?].===&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;25991386&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
&lt;br /&gt;
This article focuses on the current context of national and international recommendations, techniques development to evaluate and preserve fertility and patients' claims, this study aims to make a survey about the management of patients' breast cancer regarding oncofertility. This article concludes that , in order to satisfy patients' requests, several improvements have to be made regarding the patients' information, the health professionals' awareness and care coordination.I don't go through it now but very interesting article to read and useful for our group project.&lt;br /&gt;
&lt;br /&gt;
===Emergency fertility preservation for female patients with cancer: clinical perspectives.===&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;26026071&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
&lt;br /&gt;
This article explains about clinical perspectives to explore the new as well as the currently available options and strategies that can be used for emergency fertility preservation of female cancer patients.Such options include emergency ovarian stimulation, embryo freezing, egg freezing, ovarian tissue freezing and autotransplantation, in vitro maturation, and ovarian protection techniques. This article also mentions the advantages and disadvantages of each option as well as a new comprehensive multi-step strategy for these situations.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===Sexual dysfunction and infertility as late effects of cancer treatment===&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;26217165&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
&lt;br /&gt;
As all we know, Sexual dysfunction is the main consequence of cancer treatment. Problems are usually linked to damage to nerves, blood vessels, and hormones that underlie normal sexual function. This article emphasizes on these sexual dysfunction and does in depth. It addresses that innovations in cancer treatment such as robotic surgery or more targeted radiation therapy have not had the anticipated result of reducing sexual dysfunction. Therefore, advances in both technologies and in knowledge about how cancer treatments can damage fertility, offer hope to patients who want children.&lt;br /&gt;
&lt;br /&gt;
===Impact of fertility preservation counseling and treatment on psychological outcomes among women with cancer: A systematic review===&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;26264701&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
&lt;br /&gt;
This article explains about psychological outcomes in female cancer patients who undergo fertility preservation counseling/consultation (FPC), with or without fertility preservation (FP).I read through the whole article as I found it really interesting and relevant to our group project. This is another subheadings we can add to those.&lt;br /&gt;

===Variability in the practice of fertility preservation for patients with cancer.===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;26010087&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This is an interesting article on how reproductive endocrinologists counselled cancer patients on fertility preservation. This is relevant to our group projects because it gives us an idea of what techniques and services are currently being utilised to help women. &lt;br /&gt;
&lt;br /&gt;
===Strategies for fertility preservation in young patients with cancer: a comprehensive approach.===&lt;br /&gt;

This article recognises that as cancer treatment improves the life span of patients, with it comes the treat to fertility. It is a great article as it clearly states what methods are currently available for addressing fertility preservation in males and females. &lt;br /&gt;
&lt;br /&gt;
===Clinical guide to fertility preservation in hematopoietic cell transplant recipients.===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;24419521&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article focuses specifically on patients suffering infertility due to hematopoietic cell transplantation. It lists the options available to the patients whether female or male, which are applicable to patients who underwent other treatments and also lists the barriers to fertility preservation.&lt;br /&gt;
&lt;br /&gt;
===Fertility preservation in patients with haematological disorders: a retrospective cohort study.===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;24140311&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article addresses fertility treatment in patients with haematological disorders specifically. However, is it a really good article as it is a cohort study comparing patients at various stages in their cancer journey, such as those who have had prior chemotherapy, those who pursued ovarian stimulation and those who did not pursue fertility treatment at all.&lt;br /&gt;

Hi&lt;br /&gt;
I have added some points to the page but i will add more info soon. In terms of references and accurate citation, I have written down all the references and I will add those at the end as I might edit/delete some of them. I will explain those fertility drugs too. just added the names and do them over weekend.&lt;br /&gt;

&lt;br /&gt;
Hi everyone, &lt;br /&gt;
&lt;br /&gt;
yes, I agree we have to assign everyone a certain section to write about, I'm happy to do Infertility causing cancers ( I already found those related articles from pubmed) and Oncofertility timeline. so if everyone is happy I can start it :)&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
Hi People, &lt;br /&gt;
&lt;br /&gt;
Does anyone know how to reference a non pubmed source? I'm not sure how to reference the general information that we want to put on our page? &lt;br /&gt;
I definitely think also that we should assign everyone a certain section to cover - so that were not all just editing and adding stuff in chaos - Ive started editing the chemotherapy section of the page - i hope this is alright if i take that on- i found some good info! dont worry the stuff i have up now is no where near finished.. just having a play around with general stuff and trying to get the hang of editing etc... (literally no nothing about IT...) But at the end it obviously will be all sorted and good :) &lt;br /&gt;
&lt;br /&gt;
Thanks&lt;br /&gt;

&lt;br /&gt;
Hey everyone, &lt;br /&gt;
&lt;br /&gt;
As discussed we will be researching oncofertility as our topic for this week, and depending on how successful our research is we will decide on whether we stick to the topic or not. &lt;br /&gt;
I have added some potential subheadings to help guide our research, feel free to change them and add more. &lt;br /&gt;
We need to pick a subheading each and find research articles related to it for this weeks individual lab assessment. &lt;br /&gt;
https://oncofertility.northwestern.edu/patients/fertility-preservation-options-nu --&amp;gt; this is a good website to trigger ideas to research. &lt;br /&gt;

&lt;br /&gt;
==Peer Review===&lt;br /&gt;
&lt;br /&gt;
===1===&lt;br /&gt;
&lt;br /&gt;
Let me start off by commending this group on a fantastic page! It is incredibly thorough, detailed and long. You can immediately see that a lot of work and research has gone into it. You have a great list of references and they appear to be cited correctly throughout the page. However, some sections which appear to be incomplete and lack some citations e.g. “fertility preservation”. &lt;br /&gt;
&lt;br /&gt;
One suggestion I will make, is it would be good to see the addition of some hand-drawn images, perhaps one under either of the first 3 headings. Some more images could be used under the heading “surgery”. The videos used on this page are great. Really informative, relevant and easy to watch. I also think the “what are cancer cells” section should be higher up on the page as it is part of the basis of what the whole page is about. It also cuts between the two sections “chemotherapy” and “how does chemotherapy work?” which should be one after another. On the topic of formatting, you have a heading in there called “oncofertility timeline”, I think it would be better placed at the beginning of the page where it is more relevant. &lt;br /&gt;
&lt;br /&gt;
I also think there is just too much text in some areas e.g.  “Fertility preservation in women” and “surgery”. It makes that part of the page look clustered and difficult to read. Perhaps simplifying it more into bullet points, as you have done in other areas of the page, would be good. Conversely though, I think areas such as “targeted drugs” and “bone marrow or stem cells transplant” could use more work, however, it is possible you still intend to work on those areas anyway. &lt;br /&gt;
&lt;br /&gt;
I would suggest adding a glossary to the bottom of your page to assist in those who view your page with a lower level of scientific knowledge. You have covered an expansive range of topics pertaining to your topic, all of which are relevant and link well with each other. The page has a great focus on the learning aims of embryology. I think with some formatting corrections and some simplification of the text, this will be a really wonderful page.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
Awesome page so far guys! I commend you on your use of various videos to assist in conveying your ideas. Furthermore, the images you have chosen are highly relevant to the topic of discussion and assist the reader in gaining a greater understanding of oncofertility. All copyright information is present for the images you have used which is excellent to see.&lt;br /&gt;
It may be worth including a hand drawn image under the 'radiation' subheading, as we are required to include at least one such image. The current image under the radiation subheading could easily be replicated by hand and could fulfill this portion of the criteria.&lt;br /&gt;
&lt;br /&gt;
I am nitpicking here, but I would also recommend including some kind of media, most likely a picture, underneath the surgery subheading. It might even be worth doing the hand drawn image here if possible. A picture may also be good underneath the 'types of chemotherapy drugs' subheading, just to break up the wall of text and improve the reading experience for the reader.&lt;br /&gt;
It might also be worth restructuring the 'oncofertility limitations' subheading into the form of a table (if possible), as the bullet point format feels quite awkward and out of place compared to the rest of the page.&lt;br /&gt;
The inclusion of a glossary is also recommended, as this page will be accessible by the general public and a glossary will assist those without a background in embryology to understand and appreciate your content.&lt;br /&gt;
&lt;br /&gt;
Keep up the great work guys! Your page is absolutely amazing so far and the effort you have put in is definitely reflected in the high quality of your page.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===3===&lt;br /&gt;
&lt;br /&gt;
'''COMMENDATIONS'''&lt;br /&gt;
&lt;br /&gt;
•	The short video was a good visual aid that helped me understand your topic. &lt;br /&gt;
 &lt;br /&gt;
•	The use of tables and a few images were good additions to your page. &lt;br /&gt;
&lt;br /&gt;
•	Good referencing throughout.&lt;br /&gt;
&lt;br /&gt;
•	Your “Oncofertility Timeline” was great; straight to the point and well organised. Maybe place it at the beginning of your page as a part of your introduction? &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''RECOMMENDATIONS'''&lt;br /&gt;
&lt;br /&gt;
•	Make sure your proofread your work; I saw a few very long sentences that could be broken up into smaller sentences. This will make your page easier to read and understand.&lt;br /&gt;
&lt;br /&gt;
•	Furthermore, some words are capitalised that don’t need to be; e.g. “Oncofertility” in your introduction and “Chemotherapy” in the Infertility section. &lt;br /&gt;
&lt;br /&gt;
•	Your page would benefit from the use of subheadings. There are large chunks of information under your headings, making it a bit difficult to follow at times (particularly in your Radiation section). &lt;br /&gt;
&lt;br /&gt;
•	I recommend reading through your information and removing details that may be excessive. By making your information more concise, your page will flow better and will encourage the audience to keep reading. Some of the information is a bit repetitive across your sections.&lt;br /&gt;
  &lt;br /&gt;
•	I liked the use of a table in “Fertility Preservation in Men,” however, I feel as though you could add more details to it. I found the concepts presented in this table difficult to understand; maybe link it a bit better to the information below? Or just organise all of the information into a table?&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Very well researched topic, with all key points being addressed. Condensing all of your research and being a little more selective about what you include will be the key to a great final page.&lt;br /&gt;
&lt;br /&gt;
===4===&lt;br /&gt;
&lt;br /&gt;
The wikipage looks like it’s progressing very well, especially with the amount of content and references I can safely say you guys have worked hard on it and have done a substantial amount of research so well done guys. I liked the flow chart that you guys inserted, it really simplified the understanding of the IVF procedure as opposed to reading lengthy text. I also particularly liked the collapsible timeline which was presented very nicely and summarised the progress of oncofertility over time very well. &lt;br /&gt;
&lt;br /&gt;
As for improvements, the references definitely need to be fixed up. There were multiple appearances of the same reference and some of the links also did not work such as reference 24 and 25. On top of that the referencing for the websites were not in a consistent format and some were also done incorrectly so be sure to fix that up. I would also look out for the type of sources used such as webmd and medianews today. I’m not entirely sure if they are reliable or acceptable but I suggest you consult Mark about that. &lt;br /&gt;
&lt;br /&gt;
Additionally, the use of tables is a very good way of presenting information however, for the tables under the topic of fertility preservation for both men and women I initially though that each of the columns was a comparison against each other. Only later did I realise that each of the columns contained an individual list of treatments. To minimise the confusion I suggest rearranging the table and labelling row 1 as ‘Before treatment’, then row 2 as ‘During treatment’ and finally row 3 as ‘After treatment’ then collectively placing the treatments in their rightful spaces in the following column. &lt;br /&gt;
&lt;br /&gt;
A glossary is also missing from this page, having the definitions of the more difficult terms would assist with understanding the topic. Also on another note in the ‘Types of Chemotherapy drugs’ section, I think it would look more aesthetically pleasing if bullet points were used rather than the dashes. &lt;br /&gt;
&lt;br /&gt;
Overall, there is a substantial amount of content, and great use of images, videos and tables. Keep up the good work! &lt;br /&gt;
&lt;br /&gt;
===5===&lt;br /&gt;
&lt;br /&gt;
This page is progressing really well. You have lots of content aided by some videos and relevant images. You have discussed extremely relevant aspects of your chosen topic, which is highly commendable, however the page seems very content heavy. I would suggest making the bolded headings as actual subheadings to make it easier for the reader to ‘jump’ sections. This is evident for sections “Surgery”, “Fertility Drugs”, and “Fertility Preservation in Men and Women”. To break up the text further and keep the page exciting for your audience, consider using bullet points to convey your information under the sections previously mentioned. You have used dashes (-) but perhaps the different colour and layout of the bullet points will make your page much neater. &lt;br /&gt;
I should also note that the oncofertility timeline has been condensed well. You may want to move it to the top of the page for readers to understand the history of oncofertility and its progression. &lt;br /&gt;
&lt;br /&gt;
The videos you have incorporated are very insightful and easy to understand. The same can be said for the images on the page as they help to explain the information you have laid out. The only exception I have is for the images under “Radiation” and “Chemotherapy”. Although they are relevant and simple, you may want to replace them for a diagram or flow chart that is more practical to the reader. For example, you could draw a diagram or flow chart of how radiation and chemotherapy eliminate cancer cells. Because you have a lot of text, try adding more images, videos, or condensing the information into a table, especially in “Surgery”, “Types of Chemotherapy Drugs” and “Fertility Preservation”. &lt;br /&gt;
&lt;br /&gt;
Throughout the page, there are areas that have not been focused on as much as others. This includes “Artificial Insemination” and “In-Vitro Fertilisation” where there is very little content. These processes are currently really big in the fertility industry so with more research, I am certain there will be relevant articles to use for your page. You could also refer to these studies specifically to support the content, and discuss their success rates. &lt;br /&gt;
&lt;br /&gt;
The references have been cited inconsistently, which can be fixed with proofreading. In particular, references 19 to 25, 33 and 44 needs to be checked as they have been incorrectly cited or are non-existent. I am also finding that content under a few sections are lacking in-text references, such as “Radiation”, “How Does Chemotherapy Work?”, “Types of Chemotherapy Drugs” and “Side Effects”. Be sure to add citations in these headings to avoid being accused of plagiarism, and to encourage further reading by your readers. &lt;br /&gt;
&lt;br /&gt;
So far this page is very impressive. The amount of information you have included, and the useful videos shown, demonstrates your hard work and efforts into making this page successful. With more editing, visual aids and content, this page will be tremendous. Well done!&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===6===&lt;br /&gt;
&lt;br /&gt;
This is an excellent group project wiki. The content covers the topic in all aspects. However, there might be excessive effort in the investigation of ‘infertility’, ’Fertility Drugs’ and ‘Chemotherapy’, which occupied more than half of your project page. They are relevant to this topic, but might need to be consolidated to balance the page.&lt;br /&gt;
&lt;br /&gt;
Images and videos are good choice in your page. It would be better if more images, diagrams, tables are added into your page to balance the texts.&lt;br /&gt;
&lt;br /&gt;
Referencing and citing are excellent in most section, although some sections seem to be lack of in-text references. You might still want to work on them.&lt;br /&gt;
Overall, this wiki is an excellent work in investigating oncofertility. It is relevant to the aim of learning embryology.&lt;br /&gt;
&lt;br /&gt;
===7=== &lt;br /&gt;
&lt;br /&gt;
Awesome page overall guys- I think everyone has agreed that it is an amazing achievement and you have done a great job. &lt;br /&gt;
&lt;br /&gt;
The amount of research and the number of resources; as well as the correctly referenced sources, is something the be very proud of. It also presents a very thorough and detailed explanation about the topic that creates a well rounded and highly informative page. I also really liked the inclusion of bolded subheadings under the &amp;quot;Surgery&amp;quot; section as it made the page easier to read; however there seems to be a little bit of inconsistency as later in the page seemingly random words are in bold text- I wasn't sure of their importance or whether you were going to include a glossary so I got a little side tracked and I found that section a bit more difficult to read. &lt;br /&gt;
&lt;br /&gt;
A few areas of improvement-- there aren't many; especially to do with the actual writing and information of this page. The first would be to include some more images, videos, tables or diagrams. Although you have quite a few already, the sheer size of the page and the amounts of information beneath each subheading means that you really do need to have more interactive elements and visual aids to help with understanding the content; I found that sometimes I got a little lost within the large chunks or writing and it became more difficult to follow. There seems to be a little bit of inconsistency throughout the page and because there are such vast amounts of information beneath most subheadings,  I think that it would be beneficial to restructure some of the sub headings such as &amp;quot;Bone marrow or stem cell transplants&amp;quot; into sub-sub-headings to aid with continuity and over all visual aesthetics of the page. Finally, another way to reduce to presence of chunks of information would be to utilise some more tables to break up the volume and density of information, especially because it is a very heavy (terminology wise) topic. &lt;br /&gt;
&lt;br /&gt;
Over all you guys have done an absolutely outstanding job and I really look forward to the final product!! Good Luck!!&lt;br /&gt;
&lt;br /&gt;
===8===&lt;br /&gt;
This page is off to a really good start!  Just skimming through the page shows that you have really done thorough research.  The page is very content heavy but it is also good to see that you guys have began to add detailed images, tables and videos.  To make the page seem less content heavy, I suggest changing some bolded heading to Subheading which will neatly and evenly space out the content; it will make it easier for the audience to read as they can just pick which heading they prefer to read. I have noticed the “oncofertility timeline” is located at the very bottom, it would be a good idea to move it to the top to show the audience the progression and history of oncofertility.&lt;br /&gt;
&lt;br /&gt;
It is great to see that you have make the use of bullet points; as a reader I would prefer to see a bullet dot rather than a hyphen (-).  I know this may be a small thing to change but it will look a lot neater. The videos used in this page is very insightful and interesting, this will keep the audience intrigued.  It is clear that some areas have not been focused on such as “Artificial Insemination”, “In-Vitro Fertilisation”, “Oncofertility timeline”, “Unique chemotherapy drugs” and “How does it effect the cancer cells”.  With more research I am sure these areas can be successfully improved.&lt;br /&gt;
&lt;br /&gt;
Extensive research have been conducted which is great to see however some references have not been cited correctly, as they are no present under the references (33, 45) while a few are repetitive (26/27, 24/25), 19 is just inconsistence.  Just a reminder that references are requires in the body of the page; so just proof read everything and include the references.&lt;br /&gt;
&lt;br /&gt;
Overall, the page is outstanding.  The content and videos shows the amount of effort you guys have put into this Wikipage.  With these peer assessments, I am certain that the page will improve a lot!&lt;br /&gt;
&lt;br /&gt;
===9===&lt;br /&gt;
&lt;br /&gt;
The website contains a lot of information and covers all key points relevant to the topic. It shows that the topic of oncofertility and cancer in general has been researched very well. The addition of many pictures, graphs and tables is useful for understanding the written contents. The videos are a great way to bring some variety into the website and illustrate cancer and chemotherapy well. It might be nice to look for videos for the oncofertility section. Making several keywords bold is a good way to stress their importance and helps readers to orientate around your website. The timeline of oncofertility is very extensive and the table is a great way of presenting this information. &lt;br /&gt;
&lt;br /&gt;
Overall, the structure of the headings is a bit confusing. It might be more logical to place the “chemotherapy” section before the “infertility” heading. Moreover the “infertility” section appears to be rather about the causes of infertility instead of describing what infertility is, so renaming might useful. The referencing overall is good, however, here and there some references are missing, for instance in “Bone marrow or stem cell transplant” or “How Does Chemotherapy Work?”.  Additionally, some references were used more than once using the wrong code, which makes them show up several times in the reference list. Check https://embryology.med.unsw.edu.au/embryology/index.php/Help:Reference_Tutorial#Multiple_Instances_on_Page to learn how to avoid this. The image ‘IVF flow chart’ does not include the copyright information.Overall, double check the copyright and referencing of the images under the chemotherapy sections. &lt;br /&gt;
&lt;br /&gt;
As for the tables comparing fertility preservation in men and women, the presentation in two identical tables is very helpful. However, adding some more information for the men one or changing something of the layout of the table would make the table look less incomplete. The way it is now makes it look a little ‘neglected’. It might be interesting to add a “current research” section and a glossary to clarify terms.&lt;br /&gt;
&lt;br /&gt;
===10===&lt;br /&gt;
You have made an awesome page! The page layout is really good which is neat and easy to read. Making the oncofertility timeline table expandable is a good idea. Lots of research and work have been done! The key points relating to the topic are clearly described. The use of images, tables and videos are appropriate and highly relative to the topic. I will make the following suggestions.&lt;br /&gt;
&lt;br /&gt;
1.	The references and citations still need to be checked, eg: the videos lack citations.&lt;br /&gt;
&lt;br /&gt;
2.	It would be better if you can use a hand-drawn image.&lt;br /&gt;
&lt;br /&gt;
3.	A glossary at the end of page will help those without background knowledge understanding the topic easier.&lt;br /&gt;
&lt;br /&gt;
4.	More images can be used since you have a heavy content.&lt;br /&gt;
&lt;br /&gt;
Overall, you have done a great job!&lt;br /&gt;
&lt;br /&gt;
===11===&lt;br /&gt;
&lt;br /&gt;
The page is very informative with a good balance of text, images and videos. Clearly a lot of research has been done to cover such an expansive topic. &lt;br /&gt;
&lt;br /&gt;
The introduction provides a good overview of the topic and the growing concern for the issue, however there was no clear cut definition of the topic. The first sentence resembles the first sentence of the actual wikipedia page so it would be good to change it. It would also be good to include a few statistics so we can get an understanding of the scope of the issue. For example what percentage of infertility is caused by cancer? You can also have this under a separate heading called Epidemiology. &lt;br /&gt;
&lt;br /&gt;
I liked that each section was covered comprehensively, however, there wasn't a coherent flow between the sub-headings. The formatting of the headings also made it difficult to know if it was a separate sub-heading or a sub sub-heading. I suggest that you should only underline the major sub headings and have all other minor headings in bold and in smaller size font. This makes it easier to read the information and makes it look more organised. The headings itself also made it hard to follow. It would be good to divide the page into the familiar sub-headings  such as cause, treatment and prevention. For treatment, it would be good to divide it into treatment for infertility and treatment for cancer.  &lt;br /&gt;
&lt;br /&gt;
The chemotherapy is section is very detailed with an abundance of &lt;br /&gt;
information which shows that a lot of research was conducted, however it does not need to be this detailed. The focus of this page should be on oncofertility and not solely on cancer treatments themselves. While background information on cancer is important, it can be delivered in a more succinct manner. &lt;br /&gt;
&lt;br /&gt;
I liked the choice of images and videos for your page. I could not find an original image on your page. You can hand draw or use Word to make a simplified version of one of the existing images on your page. &lt;br /&gt;
&lt;br /&gt;
It would be good to include a glossary at the end of the page to state the definitions of difficult terminology. &lt;br /&gt;
&lt;br /&gt;
Overall, you have researched this topic well and have provided a very detailed analysis covering the several aspects, however a few changes need to be made to the structure and organisation of the page to make it more coherent.&lt;br /&gt;
&lt;br /&gt;
===12===&lt;br /&gt;
&lt;br /&gt;
Great work so far on your wikipage guys, even just at first glance it is clear how much research and work was put in to make this page what it is. The amount of information that has been provided on the page is quite substantial. Within the contents table at the top of the page, each section has been broken down accordingly allowing ease of navigation for those who wish to know more about Oncofertility. The introduction provides us with a nice description of what Oncofertility is as well as a definition of the term ‘infertility’ which is helpful to those who do not know much information regarding the terms&lt;br /&gt;
&lt;br /&gt;
I think that some information can be split up into more paragraphs, especially information in the subheading ‘Radiation’, currently it is just a wall of text which makes it extremely hard to focus and understand all the words. Seeing as it is a procedure, maybe someone can include a hand-drawn image of the process and how affects the body?&lt;br /&gt;
&lt;br /&gt;
Information in the other sections are well organised and provides useful relevant information as well as providing deeper knowledge into certain techniques, chemicals and cancer cells in general. The information is a good addition (for both cancer cells and chemotherapy  however there is no referencing available to be found for both your videos. I think more images (hand-drawn or from other resources) need to be added to balance out the amount of text you have on your page.&lt;br /&gt;
&lt;br /&gt;
The overall structure other than the main subheadings that you currently have could be improved as some sections are just too long and cover a too broad information to be just kept under one subheading. Make use of more dot points to summarise the information. The table under Fertility preservation in women was concise and provides easy to read data, however the colouring of the background makes it hard to distinguish where each section of the box finishes and ends (maybe I’m colour-blind). I also think that it might be helpful to add a glossary to the bottom of your wikipage as there are quite a lot of terms that people may not understand &lt;br /&gt;
&lt;br /&gt;
Overall great work on your wikipage, I look forward to reading the final version!! Good luck!&lt;br /&gt;
&lt;br /&gt;
===13===&lt;br /&gt;
&lt;br /&gt;
This project contains a lot of information, but right from the beginning through to the end it is obvious that it is unclear and hard to follow, all the information is placed there but needs to be clarified further and made easier to read. Diagrams and videos are used which help giver a richer understanding of the project. A large reference list cited all over the project validates the sources of information.&lt;br /&gt;
&lt;br /&gt;
In contrast to the large amount of information and few diaphragms and videos used, there should be more diagrams used, such as histological slides, timelines, YouTube videos and hand drawn diagrams. This would help the readers have an easier time following the path of this report as at the moment it is just a lot of information with few diagrams and videos. The use of sub headings followed by more subheadings is a very good way to organise the information in which they have done well.&lt;br /&gt;
&lt;br /&gt;
Lack of a glossary won’t help the readers if they haven’t heard of certain things, so a glossary is advised to be added in. Although the amount of information is a clear indication of the amount of research and valuable information found, the clarity of the project needs to be addressed as it will bring the entire project together.&lt;br /&gt;
&lt;br /&gt;
===14===&lt;br /&gt;
Your information extends beyond what is expected, but also extensive and readable and engaging. The page is formatted really well.&lt;br /&gt;
&amp;lt;b&amp;gt;Pros&amp;lt;/b&amp;gt;&lt;br /&gt;
*The structure of your page is really good. It flows well, all headings and subheadings were chosen really well, the use of diagrams keeps it engaging&lt;br /&gt;
*Each subheading is chosen and highlighted well&lt;br /&gt;
*A very extensive reference list, making it evident that you have researched your topic thoroughly!&lt;br /&gt;
&amp;lt;b&amp;gt;Cons&amp;lt;/b&amp;gt;&lt;br /&gt;
*Use of diagrams and photos in the introductory parts of your page will make your page much more engaging&lt;br /&gt;
*You may have extensive information but its not too concise. At a glance of your page, all you see are huge jumbles of words, and if you read the information, it needs to be summarized a lot more&lt;br /&gt;
*Photos in Surgery and Fertility Drugs can make it more interesting and it can help you explain them more on what it looks like and whats involved using a single image&lt;br /&gt;
*The use of the video explanation is also very good, but keep in mind that this page isn’t really aimed for people with minimal knowledge on cancer cells, but those trying to extend their knowledge, so they would already know about cancer cells. (Less is more)&lt;br /&gt;
*Use a table in Chemotherapy Drugs can make long lists look much better&lt;br /&gt;
*Reserve subheadings for your bold keywords underneath “Fertility preservation in women” instead of just bold type, it will look much more organized&lt;/div&gt;</summary>

--[[User:Z8600021|Mark Hill]] ([[User talk:Z8600021|talk]]) 11:20, 25 September 2015 (AEST) OK I discussed this with your group in last week's lab. you have not shown animal models, graphics, histology, media etc to really build your project page. The introduction does not give me a clear idea of the scope of the project. Not ready for peer review.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Hey guys, I have just had a really quick look on PubMed and I found a good starting article. Its a review article (I'm pretty sure) so I'm not sure if we can use it, but it discusses some interesting genetic causes of male infertility and also references a lot of primary articles. &lt;br /&gt;
&lt;br /&gt;
PMID 26178295 &lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
I can't seem to view anything but the first page of the article but the introduction gives a good idea on what male infertility is and how it arises. At the moment I have found 2 research articles that address factors that can increase male fertility. Although they do not address male infertility conditions specifically, in the discussion they imply that these methods can be applied to men who have them such as oligospermia and azoospermia. I feel as though we can use these articles when discussing alternative therapies for successful conception. Please have a read and share your opinions! &lt;br /&gt;
&lt;br /&gt;
PMID 22958644 - note that you can only view the condensed version of this article&lt;br /&gt;
&lt;br /&gt;
PMID 26097523 - you can view the whole article on biomed (subheadings in the discussion particularly addresses male infertility)&lt;br /&gt;

&lt;br /&gt;
Hey guys, it was pretty hard finding research articles from Pubmed regarding the epidemiology of male infertility.  For now, I have found an article about sperm extraction which I thought could be an alternative for treatments.  However I can't view the full article without paying, but the abstract from Pubmed seems to sum it up.&lt;br /&gt;
So, I came across a research article addressing the epidemiology and aetiology of male infertility, through Pubmed it doesn't have a direct link to the full PDF article however I linked it you guys on Facebook so have a read!&lt;br /&gt;
&lt;br /&gt;
PMID 22128297&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
Hello everyone! To get started, I just added a few headings on the page where you can add your research/review articles. Feel free to add more subheadings or change the wording of the titles - I'm sure we will need to as we research more. From looking at other groups' pages, I think it is also important we add a bit of 'Background Information&amp;quot; regarding the process of spermatogenesis and how any abnormalities can cause infertility so we can all look for articles as we go. Remember we are targeting this towards students like us, so a bit of key background info is essential. &lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
I just posted the articles that I found on male infertility. It was kind of hard to find ones because I stuck to studies in humans- but i found some good ones that were studies on rats (not sure if we can use them) and also some good secondary or review articles that we could use as background information maybe? So I'll just post the PMID's here..&lt;br /&gt;
* PMID 26303086&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
Not sure if we are review articles are any good, but I thought that it's also important to talk about &amp;quot;detecting abnormalities&amp;quot;.  I came across this review article which talks about the &amp;quot;male genital tract - colour dopple ultrasound&amp;quot; is a useful tool to detect impaired reproductive health.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
Good thinking! If anyone comes across more articles regarding this, please post them up! I'll add a 'diagnosis' sub-heading to the page &lt;br /&gt;
&lt;br /&gt;
--[[User:Z3462297|Z3462297]] ([[User talk:Z3462297|talk]]) 22:23, 27 August 2015 (AEST)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Hey guys, found a couple of articles describing different methods of ARTs for male infertility:&lt;br /&gt;
&lt;br /&gt;
These 2 talk about Intrauterine Insemination (IUI)&lt;br /&gt;
PMID 26294874&lt;br /&gt;
PMID 26288981&lt;br /&gt;
&lt;br /&gt;
Also, another potential sub-heading to research might be the risks involved different ARTs&lt;br /&gt;
E.g. the following article about the prevalence of birth defects after a number of different male-related ARTs&lt;br /&gt;
PMID 26265143&lt;br /&gt;
&lt;br /&gt;
--[[User:Z3462833|Z3462833]] ([[User talk:Z3462833|talk]]) 23:38, 27 August 2015 (AEST)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
That sounds good. I think mentioning risks are important to show what is successful and what isnt. Feel free to add it under the &amp;quot;ART&amp;quot; heading (as a sub-heading)&lt;br /&gt;
&lt;br /&gt;
--[[User:Z3462297|Z3462297]] ([[User talk:Z3462297|talk]]) 23:06, 31 August 2015 (AEST)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Hey I found this article that discusses some ARTs for infertile men. Its not a bad read and has info on two different methods, Intracytoplasmic morphologically selected sperm injection (IMSI) and conventional intracytoplasmic sperm injection (cICSI). You can read the full text on biomod &lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
LOOK! &lt;br /&gt;
This is a really good review article that talks about causes, diagnosis AND treatments. I recommend everyone to read it!  &lt;br /&gt;

&lt;br /&gt;
==Peer Assessment==&lt;br /&gt;
&lt;br /&gt;
===1===&lt;br /&gt;
&lt;br /&gt;
To start, I think some of your subheadings are a bit unnecessary, for example, you could get away without having the subheading “background information” and just having the sub-subheadings as subheadings below your intro. Whilst some subheadings are good as it helps break down the info in the table of contents, it makes the actual page difficult to read and follow. &lt;br /&gt;
&lt;br /&gt;
Great use of images on the page. There are many, without it cluttering the page and they are simple and relevant. However, the pictures you have used under “background information” appear to be a bit lifeless and complex. Perhaps using more simplified images with some colours would help liven up the section as well as allow people who use this page, with less scientific knowledge than you, to understand what they are seeing. They are important images as they set the basis for the rest of the page. It would also be good to see a hand-drawn image on the page. &lt;br /&gt;
&lt;br /&gt;
Your use of tables is also great, it really helps to break down the information. I would suggest however, you include a little more information and references under the section “male infertility disorders”. It is a big vague and there are no citations.  Your list of references is incredible and you should be commended on that. It shows a great deal of research has gone into this page. Your citations appear to be correctly done throughout the page. Your “Causes of fertility” section is done really well and is very thorough. The video accompanying it is good to as it is easy to understand and explanatory. Your “risk factors and prevention” heading could use more work. I would suggest actually splitting them up into two separate headings and really delving more into prevention and how to handle infertility. &lt;br /&gt;
&lt;br /&gt;
Your “treatment” section is really well done and thorough. I would suggest however, to make it easier to read, that you simplify some of your paragraphs into bullet points. A glossary section may also be useful for people reading this page with a lesser degree of embryology knowledge than you or I. I will say, this page has covered its chosen topic well and has attacked it from an embryologically focused angle. Lastly I would suggest including a section on animal models and the literature for the more advanced student.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
Very impressive work so far guys! Your page covers a comprehensive topic very well, without focussing too much on certain subheadings at the expense of others. Your use of both tables and images is excellent so far. All necessary copyright information seems to be present for the images that you have uploaded. It's good to see that you have also included a video to give some variety to the media on your page. The 'background information' gives context to the issues which you discuss and though it might not be of great use for someone familiar with embryology, it would be a great help to those with no experience in this field and is therefore useful in establishing the topic of male infertility.&lt;br /&gt;
&lt;br /&gt;
The only things that could be changed to improve your wiki page is perhaps altering the location of tables and pictures on your page. For example all pictures are located on the right side of the page, although not a significant issue, becomes slightly monotonous as one progresses through the page. It may be worth alternating pictures between left and right to mix things up a little bit and improve the overall flow of the page. &lt;br /&gt;
It might also be worth including a short video underneath the 'surgical treatments' subheading to give a visual example of some of the techniques discussed.&lt;br /&gt;
&lt;br /&gt;
Furthermore a subheading on future research could possibly be included under the 'treatments' subheading to give the reader information on techniques and therapies which may come to prominence in the near future.&lt;br /&gt;
&lt;br /&gt;
Your wiki page thus far is very impressive! Excellent work so far.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===3===&lt;br /&gt;
&lt;br /&gt;
Probably the most enjoyable page to read, thus far.&lt;br /&gt;
&lt;br /&gt;
'''COMMENDATIONS'''&lt;br /&gt;
&lt;br /&gt;
•	Great introduction; straight to the point and easy to understand. &lt;br /&gt;
&lt;br /&gt;
•	Your information is organised under appropriate subheadings, making your page easy to read and follow. &lt;br /&gt;
&lt;br /&gt;
•	Your “Types of Male Infertility” table is great! You have provided clear definitions of each condition and the use of colour makes the information stand out. &lt;br /&gt;
&lt;br /&gt;
•	Appropriate referencing throughout.&lt;br /&gt;
&lt;br /&gt;
•	Great audio-visual sources, especially the video. &lt;br /&gt;
&lt;br /&gt;
•	Your page looks even better than a Wikipedia page! A lot of time and effort has gone into it.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''RECOMMENDATIONS'''&lt;br /&gt;
&lt;br /&gt;
•	A glossary at the end of the page would be great, even though you have explained a lot of the concepts in your text. This way the reader does not have to skim through your page to find a term and they can go straight to the glossary.&lt;br /&gt;
&lt;br /&gt;
•	Information under IVF and IUI is absent in “Male Infertility Treatments.” I am not sure if these were meant to be deleted or text will be added later.&lt;br /&gt;
&lt;br /&gt;
It is evident that you have worked fantastically as a team and you have done a lot of research. Each topic is covered comprehensively and aided by a table, image or diagram, making the topic more appealing to the reader. Well done!&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
===4===&lt;br /&gt;
&lt;br /&gt;
The wikipage is very well organised and the headings, subheadings and tables made everything easy to follow. I particularly liked the blue theme you kept with all the tables, it is very aesthetically pleasing. In terms of content the background information provided a clear overview of the subject especially the information about the physiology of fertility in males which laid down the foundation some basic knowledge surrounding male fertility under normal circumstances which I found useful in grasping other concepts throughout the page. The page is filled with an extensive amount of content and along with the long list of references I was given the impression of good understanding of the topic and commendable effort placed into the research.&lt;br /&gt;
&lt;br /&gt;
One thing I found that wasn’t quite compatible with your page was the inclusion of the video in the ‘Causes of infertility section’. Although I do agree that it is a very good video, it had little information surrounding male infertility and was more about infertility in general. Perhaps a video exclusively about male infertility would be more suitable for your page.  &lt;br /&gt;
&lt;br /&gt;
As for some additional improvements, it would be beneficial to include a glossary to explain some difficult terms that would help the audience gain a better understanding of the content. Also, the addition of a hand-drawn image would also be nice. A suggestion would be to exchange your existing ‘components and structure of spermatozoa’ image with a more simplified and schematic diagram of the structure of sperm. &lt;br /&gt;
&lt;br /&gt;
Overall, I enjoyed reading about male infertility and the page is coming together very nicely.&lt;br /&gt;
&lt;br /&gt;
===5===&lt;br /&gt;
&lt;br /&gt;
The introduction is a really important part of the project so it’s important that you get that down. The introduction is well written but it is not done yet as it does not give me a clear idea of the scope of the project. You need to explain the topic in more depth to give readers overall understanding of the male infertility. Maybe think about adding an image to make it a bit more appealing.&lt;br /&gt;
&lt;br /&gt;
Overall this is a well-produced project so far, very impressed. First thing noticeable on the page is the amount of information you have which is great. Only minor changes to polish up some sections are needed which I will explain as we go on. The project as a whole is not text heavy with some good images, tables, diagrams and a short video included which again are helpful in guiding the information. The table in “Diagnosis” section is great and really well done. One thing you could maybe do here is add a few diagrams or images related. I know you have added 2 images down below but I think it’s something that might make it even easier to follow. Try to add more related images to the content of the table. For the “Male infertility disorders”, I believe you can find more information and add to the table as this topic is a big vague and broad. Most of the sections have great amount of detail with a number of in text citations and this is great to see except for the table used in “Male infertility disorders”. Try to fix this up as citations should be carried through the entire page. Other than that, all the citations formatted correctly and it is good that all the references appear in one long list at the end of the page. Well done!&lt;br /&gt;
&lt;br /&gt;
Some sections like “Intrauterine Insemination (IUI)” or “IVF” seems to be untouched. I’m assuming you are still in the process of adding content. However, the “Treatments” section is extensive and well researched. Good job. &lt;br /&gt;
&lt;br /&gt;
To sum up, in terms of improvement, my suggestions are: &lt;br /&gt;
&lt;br /&gt;
•	There is no hand drawn image yet .You may only have 1-2 weeks to complete this project so don’t leave it until last minute.&lt;br /&gt;
&lt;br /&gt;
•	Add more related videos to create the balance.&lt;br /&gt;
&lt;br /&gt;
•	The project could benefit from having a ‘Glossary’ list so that viewers can understand some uncommon words.&lt;br /&gt;
&lt;br /&gt;
•	You have not shown animal model so this can be a potential subheading as well as “future research” or “current research”. Just some tips, when researching on pubmed, there's an option to look at recent articles by customising dates to say 2012-onwards&lt;br /&gt;
&lt;br /&gt;
•	In text-citation &lt;br /&gt;
&lt;br /&gt;
•	Simplify some of your paragraphs into bullet points. This can be done for “Causes of Infertility” or “Treatments”.&lt;br /&gt;
&lt;br /&gt;
•	Finish those untouched topics&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Overall, the project page is interesting, easy to comprehend and follow, however certain changes should be addressed and more information added.&lt;br /&gt;
&lt;br /&gt;
===6===&lt;br /&gt;
&lt;br /&gt;
I’ll begin by commending you on a well contructed wikipage with a great balance of texts and figures. You have used a great variety of supporting resources which complement your text well and aid in the teaching and the understanding of your key points which you have chosen well and mostly covered sufficiently. I particularly liked that you included a graph, (since you are the first project I see with one) and your widespread use of tables which breaks up the text whilst teaching your content well. Good job on being consistent in using the same colour and formatting in your tables. Your explanations are clear and extensive with the main points covered well. Your topic appears to be well research with a thorough list of references and your citations are correct. &lt;br /&gt;
&lt;br /&gt;
While you have included a great table on the types of infertility in males with a brief explanation of each, I feel like this should be elaborated on further. Also, your background information is well written however I feel it is too abrupt. You can include an introductory sentence or paragraph to your subheadings. While it is great that you included a video, I don’t feel like it is relevant to where you have placed it under the causes heading. Since it is more of an overview of infertility in general you can move it to the beginning of the page if you would like to keep it or choose a different video. &lt;br /&gt;
&lt;br /&gt;
While I did say your explanations in general are well written, some areas need more focus, such as your explanation of Varicocele, while you have said that varicocele leads to infertility and explained what is was, it wasn’t clear to me why it causes infertility. Also you should add more significant research beyond the teaching aspect by including some studies conducted and animal models. You can contribute further to the teaching and understanding of your topic by adding your own innovative, drawn diagrams to your great selection of files already added. Just a final formatting point, your images need a higher resolution, most of them are unclear and the words are not very readable. You can edit this by increasing the current 300px resolution to the appropriate pixels. &lt;br /&gt;
&lt;br /&gt;
Great progress overall, good luck with the rest!&lt;br /&gt;
&lt;br /&gt;
===7===&lt;br /&gt;
The topic is well investigated in this project wiki. It is excellent that you also include some background information on the structure and development of spermatozoa, which would help readers without knowledge in this field.&lt;br /&gt;
&lt;br /&gt;
Images are properly cited and referenced. They make the page looked refreshing. Tables are used wisely to summarize information on ‘male infertility disorders’, but will need some more in-text referencing with the table contents.&lt;br /&gt;
&lt;br /&gt;
Paragraphs are written very well. There are great efforts in rewriting and summarizing. It will be better if the texts can be simplified by some diagrams or lists, which will be easier for readers to get through. Overall, this project wiki is an excellent work.&lt;br /&gt;
&lt;br /&gt;
===8===&lt;br /&gt;
The website is very well organized and contains a lot of researched information and content. The introduction gives a short and precise definition of male infertility and let’s the reader know what to expect from the website. Overall the order of the headings and subheadings is very logical. To start off with explaining the healthy male physiology is a smart way to allow readers with less knowledge about the topic to understand the website. The blue theme of the tables is very coherent and the recurrent incorporation of the tables is alternative to plain text. The “treatment” heading has a lot of information ranging from traditional to Western medicine, which shows that the topic was very well researched. &lt;br /&gt;
&lt;br /&gt;
In addition, it is good to see that at the end of the treatment section (upon completion) the page will give a direct link to ART. The referencing of the website and the images is correct. Here and there are some paragraphs or tables that are not referenced yet (Classifications of Valsalva manoeuvre, Intro. of “Diagnosis”). The amount of references is extensive showing again that the topic has been researched quite well.  The images are very useful, for understanding the content of the website. Particularly the diagrams explaining the Varicocele and the mechanisms of Lycopene Treatment clarify a lot. The timeline of the development of gonadotropin preparations is also a great way to incorporate bits of the history of your topic without spending too much text on it. &lt;br /&gt;
&lt;br /&gt;
It might be useful to add another heading about current research and a glossary to help readers to understand the website. It is really great that you added a video to your website, particularly in the beginning as it will introduce to topic to readers and ease them into the topic. However, it might be reasonable to look for a video that only focuses on male infertility. If that cannot be found it would not be too bad, as the video is still relevant to the topic overall. Moreover, try to add a self-drawn image, maybe in the treatments part for the surgical interventions?.&lt;br /&gt;
&lt;br /&gt;
===9===&lt;br /&gt;
&lt;br /&gt;
Firstly, you have done an exceptionel job in creating such a well organised page with the right amount of images and videos. It is also evident that a lot of effort was taken to make sure each section is covered comprehensively which is a mark of great teamwork. &lt;br /&gt;
&lt;br /&gt;
You have added images and videos at the right places to make it easier for us to absorb the information, however I could not find an original image. Perhaps you could use a flowchart from one of the existing images to make your own simplified version using Word. &lt;br /&gt;
&lt;br /&gt;
The sub-headings are very appropriate and ensure that there are no big blocks of text. My only suggestion would be to cut down on the background information regarding spermatozoa and spermatogenesis. While this is important in providing us with an insight into male reproduction, a paragraph at most would suffice. Under Male Infertility Treatments with ARTs, there are a few sub-sub headings that don't have any text underneath them. &lt;br /&gt;
&lt;br /&gt;
I really liked the use of a table under Risks and Prevention as it breaks the monotonous style of reading paragraphs of text.  &lt;br /&gt;
&lt;br /&gt;
At the end of the page, it would be helpful to include a glossary as there are a few terms that are hard to understand. &lt;br /&gt;
&lt;br /&gt;
I really commend you on being able to produce such a well crafted page that the readers can enjoy going through. Great team work!&lt;br /&gt;
&lt;br /&gt;
===10===&lt;br /&gt;
&lt;br /&gt;
This page is really with high quality. The key points relating to the topic are clearly described. The page is organized very well which is neat and easy to read. The headings and subheadings are appropriate and easy to follow. The video is relative to the content and the images are well chosen. The choice of background color of the tables is pretty good which makes the page nice but still easy to read. The video is well referenced. Other references and citations are appropriate as well. I will make the following suggestions:&lt;br /&gt;
&lt;br /&gt;
1.	A glossary at the end of page will help those without background knowledge understanding the topic easier.&lt;br /&gt;
&lt;br /&gt;
2.	An animal model and the current research may be included in your page.&lt;br /&gt;
&lt;br /&gt;
3.	A hand-drawn image can be added.&lt;br /&gt;
&lt;br /&gt;
Overall, this is a good teamwork and you have made a great page.&lt;br /&gt;
&lt;br /&gt;
===11===&lt;br /&gt;
&lt;br /&gt;
I would like to say great work of find substantial information and images to go along with your wikipage. From the table of contents there seems to be a lot of topics being addressed and with your use of subheadings, it makes navigating the page much easier. The short introduction described the basic meaning of male infertility well as well as the inclusion of some basic statistics is a nice bit of information however it would be nice to have some information regarding what your wikipage will be covering in general&lt;br /&gt;
&lt;br /&gt;
The background information is very useless as it provides the reader with some basic knowledge of where the male reproductive system and its components come into play in regard to the topic of male infertility. The images used are all referenced appropriately and assists in understanding where each component is located and what they look like. The tabulated data of the different types of male infertility allows the readers to easily understand the different kinds and what their relative symptoms are easily. Good job on that! The use of video is nice to see, it has relevance to your topic.&lt;br /&gt;
&lt;br /&gt;
Regarding information within the section ‘Major Causes of Infertility’, the information provided is awesome, however there just seems to be too much information crammed into small paragraphs which makes it quite draining to read. There are many terms which some readers may not know or understand, so I recommend using a glossary to help sort this problem out  maybe simplify the information (if you can)  or break up into more paragraphs to make it easier to read and digest. There are some sections which have no information, however I know that these will be filled by the submission date. The large amount of references is indicative of how much work went into the wikipage for your group! &lt;br /&gt;
&lt;br /&gt;
Good work guys!!&lt;br /&gt;
&lt;br /&gt;
===12===&lt;br /&gt;
&lt;br /&gt;
This group project is so far the most detailed, it has the most information included. Many topics followed by sub topics followed by even more sub topics is a clear indication of the amount of research they have undergone. Multiple diagrams, YouTube videos, flowcharts, microscopic images, histological slides, ultrasonography, timelines and tables were very useful in supporting the information they have and helps give a clear understanding of male infertility. 68 references included a vast search for research they did which is a general indication of reliability so as the multiple citations used throughout the report.&lt;br /&gt;
&lt;br /&gt;
Lack of a glossary doesn’t help the reader as this report is a general but very large topic, with all the information they have included, the readers are bound to come across a fair amount of words or phrases they will not understand. No symptoms are recorded down, and also in the risk factors and prevention section, only one table is included. Perhaps more information regarding the prevention is required.&lt;br /&gt;
&lt;br /&gt;
Overall the project is done quite well, although if a reader was to judge on its clarity they may find it a bit hard as there is a lot of information which could do with a bit of clarity, possibly but separating, bullet points or tables. A glossary should definitely be added as it plays a very important role for the reader’s benefit.&lt;br /&gt;
&lt;br /&gt;
===13===&lt;br /&gt;
&lt;br /&gt;
This Group Project is impressively detailed and provides a comprehensive view of male infertility detailing the normal process as well as the various disorder types and causes. The wikipedia page flows logically, provides excellent summaries and may well be an excellent educational resource. The video chosen is fantastic and tables have been used well to present information quickly.&lt;br /&gt;
&lt;br /&gt;
I find that the Introduction is clear and concise. However, i feel it may be improved further by an introductory visual. Other than that, the page has many relevant diagrams and images. In terms of the 'development of gonadotropin preparations', it does seem a little out of place as it isn't particularly referred to in the text. I understand timelines add a richness to the text and can give perspective, but i feel that it may be of more relevance if given regarding male infertility treatments as a whole, rather than gonadotropin preparations. Of course, you can always have both.&lt;br /&gt;
&lt;br /&gt;
Other than that, I am quite impressed with this wikipedia page. It is referenced well and information is backed with reference to the findings of various studies. A final tip may be to add a simple glossary for ease of reference as opposed to having to scroll back up to the section (e.g. varicocele) to remind oneself of the meaning. However, it should be commended that jargon was defined well throughout the article.&lt;br /&gt;
&lt;br /&gt;
===14===&lt;br /&gt;
&lt;br /&gt;
Great work guys, a lot of information in there.&lt;br /&gt;
Well referenced and easily readable. Nicely broken up with some informative images.  Tables are great and make it easy to find information on a big page. And the first embedded video I’ve seen which is nice.&lt;br /&gt;
Looks like it all the information is there already just a couple of heading to finish off so well done.&lt;br /&gt;
Stylistically the only things ill pick on are,&lt;br /&gt;
The numbered list in treatments, doesn’t fit with the formatting of the rest of the page. Just turn them into subheading or tables like the others. &lt;br /&gt;
Some of the tables are standalone ie. Male infertility disorder that should really have some intro text to them. Also make sure they have a description underneath each one describing what’s in table. And reference of where the information’s coming from.&lt;br /&gt;
You could add a section on epidemiology/prevalence of types of infertility. But the intro could be enough if you flesh something out in there.&lt;br /&gt;
Don’t forget to hyperlink some of the important words to the sites glossary and other pages so people can find extra reading or background. And I think you’ll have a really informative page. &lt;br /&gt;
Fantastic work guys.&lt;br /&gt;
&lt;br /&gt;
===15===&lt;br /&gt;
*The structure of your page is extremely excellent! It flows very well, all headings and subheadings were chosen really well, the use of tables and diagrams are incredible!&lt;br /&gt;
*The heading of “Background information” is VERY extensive, and also concise! The diagram placement is also excellent, and their use is also extremely excellent&lt;br /&gt;
*The use of the video to explain the cause of infertility is absolutely amazing, it makes your page look good, keeps your explanation short, concise, and readable, and it also engages the audience&lt;br /&gt;
*Each subheading under “Causes” is also very well outlined and explained, there is a lot of information there, and it is sure whatever information the reader may need would be found on your page as it has covered and explained a lot&lt;br /&gt;
Overall, all I have for your group are good comments, as I couldn’t think of anything else that you will might need to add or change on it at all! Your information extends beyond what is expected, but also extensive, concise, and, most importantly, extremely readable and engaging! GOOD WORK!&lt;/div&gt;</summary>

&lt;br /&gt;
--[[User:Z8600021|Mark Hill]] ([[User talk:Z8600021|talk]]) 11:20, 25 September 2015 (AEST) OK I discussed this with your group in last week's lab. you have not shown animal models, graphics, histology, media etc to really build your project page. The introduction does not give me a clear idea of the scope of the project. Not ready for peer review.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Hey guys, I have just had a really quick look on PubMed and I found a good starting article. Its a review article (I'm pretty sure) so I'm not sure if we can use it, but it discusses some interesting genetic causes of male infertility and also references a lot of primary articles. &lt;br /&gt;
&lt;br /&gt;
PMID 26178295 &lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
I can't seem to view anything but the first page of the article but the introduction gives a good idea on what male infertility is and how it arises. At the moment I have found 2 research articles that address factors that can increase male fertility. Although they do not address male infertility conditions specifically, in the discussion they imply that these methods can be applied to men who have them such as oligospermia and azoospermia. I feel as though we can use these articles when discussing alternative therapies for successful conception. Please have a read and share your opinions! &lt;br /&gt;
&lt;br /&gt;
PMID 22958644 - note that you can only view the condensed version of this article&lt;br /&gt;
&lt;br /&gt;
PMID 26097523 - you can view the whole article on biomed (subheadings in the discussion particularly addresses male infertility)&lt;br /&gt;

Hey guys, it was pretty hard finding research articles from Pubmed regarding the epidemiology of male infertility.  For now, I have found an article about sperm extraction which I thought could be an alternative for treatments.  However I can't view the full article without paying, but the abstract from Pubmed seems to sum it up.&lt;br /&gt;
So, I came across a research article addressing the epidemiology and aetiology of male infertility, through Pubmed it doesn't have a direct link to the full PDF article however I linked it you guys on Facebook so have a read!&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
Hello everyone! To get started, I just added a few headings on the page where you can add your research/review articles. Feel free to add more subheadings or change the wording of the titles - I'm sure we will need to as we research more. From looking at other groups' pages, I think it is also important we add a bit of 'Background Information&amp;quot; regarding the process of spermatogenesis and how any abnormalities can cause infertility so we can all look for articles as we go. Remember we are targeting this towards students like us, so a bit of key background info is essential. &lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
I just posted the articles that I found on male infertility. It was kind of hard to find ones because I stuck to studies in humans- but i found some good ones that were studies on rats (not sure if we can use them) and also some good secondary or review articles that we could use as background information maybe? So I'll just post the PMID's here..&lt;br /&gt;
* PMID 26303086&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
Not sure if we are review articles are any good, but I thought that it's also important to talk about &amp;quot;detecting abnormalities&amp;quot;.  I came across this review article which talks about the &amp;quot;male genital tract - colour dopple ultrasound&amp;quot; is a useful tool to detect impaired reproductive health.&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
Good thinking! If anyone comes across more articles regarding this, please post them up! I'll add a 'diagnosis' sub-heading to the page &lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
Hey guys, found a couple of articles describing different methods of ARTs for male infertility:&lt;br /&gt;
&lt;br /&gt;
These 2 talk about Intrauterine Insemination (IUI)&lt;br /&gt;
PMID 26294874&lt;br /&gt;
PMID 26288981&lt;br /&gt;
&lt;br /&gt;
Also, another potential sub-heading to research might be the risks involved different ARTs&lt;br /&gt;
E.g. the following article about the prevalence of birth defects after a number of different male-related ARTs&lt;br /&gt;
PMID 26265143&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
That sounds good. I think mentioning risks are important to show what is successful and what isnt. Feel free to add it under the &amp;quot;ART&amp;quot; heading (as a sub-heading)&lt;br /&gt;
&lt;br /&gt;

Hey I found this article that discusses some ARTs for infertile men. Its not a bad read and has info on two different methods, Intracytoplasmic morphologically selected sperm injection (IMSI) and conventional intracytoplasmic sperm injection (cICSI).

&lt;br /&gt;
==Peer Assessment==&lt;br /&gt;
&lt;br /&gt;
===1===&lt;br /&gt;
&lt;br /&gt;
To start, I think some of your subheadings are a bit unnecessary, for example, you could get away without having the subheading “background information” and just having the sub-subheadings as subheadings below your intro. Whilst some subheadings are good as it helps break down the info in the table of contents, it makes the actual page difficult to read and follow. &lt;br /&gt;
&lt;br /&gt;
Great use of images on the page. There are many, without it cluttering the page and they are simple and relevant. However, the pictures you have used under “background information” appear to be a bit lifeless and complex. Perhaps using more simplified images with some colours would help liven up the section as well as allow people who use this page, with less scientific knowledge than you, to understand what they are seeing. They are important images as they set the basis for the rest of the page. It would also be good to see a hand-drawn image on the page. &lt;br /&gt;
&lt;br /&gt;
Your use of tables is also great, it really helps to break down the information. I would suggest however, you include a little more information and references under the section “male infertility disorders”. It is a big vague and there are no citations.  Your list of references is incredible and you should be commended on that. It shows a great deal of research has gone into this page. Your citations appear to be correctly done throughout the page. Your “Causes of fertility” section is done really well and is very thorough. The video accompanying it is good to as it is easy to understand and explanatory. Your “risk factors and prevention” heading could use more work. I would suggest actually splitting them up into two separate headings and really delving more into prevention and how to handle infertility. &lt;br /&gt;
&lt;br /&gt;
Your “treatment” section is really well done and thorough. I would suggest however, to make it easier to read, that you simplify some of your paragraphs into bullet points. A glossary section may also be useful for people reading this page with a lesser degree of embryology knowledge than you or I. I will say, this page has covered its chosen topic well and has attacked it from an embryologically focused angle. Lastly I would suggest including a section on animal models and the literature for the more advanced student.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
Very impressive work so far guys! Your page covers a comprehensive topic very well, without focussing too much on certain subheadings at the expense of others. Your use of both tables and images is excellent so far. All necessary copyright information seems to be present for the images that you have uploaded. It's good to see that you have also included a video to give some variety to the media on your page. The 'background information' gives context to the issues which you discuss and though it might not be of great use for someone familiar with embryology, it would be a great help to those with no experience in this field and is therefore useful in establishing the topic of male infertility.&lt;br /&gt;
&lt;br /&gt;
The only things that could be changed to improve your wiki page is perhaps altering the location of tables and pictures on your page. For example all pictures are located on the right side of the page, although not a significant issue, becomes slightly monotonous as one progresses through the page. It may be worth alternating pictures between left and right to mix things up a little bit and improve the overall flow of the page. &lt;br /&gt;
It might also be worth including a short video underneath the 'surgical treatments' subheading to give a visual example of some of the techniques discussed.&lt;br /&gt;
&lt;br /&gt;
Furthermore a subheading on future research could possibly be included under the 'treatments' subheading to give the reader information on techniques and therapies which may come to prominence in the near future.&lt;br /&gt;
&lt;br /&gt;
Your wiki page thus far is very impressive! Excellent work so far.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===3===&lt;br /&gt;
&lt;br /&gt;
Probably the most enjoyable page to read, thus far.&lt;br /&gt;
&lt;br /&gt;
'''COMMENDATIONS'''&lt;br /&gt;
&lt;br /&gt;
•	Great introduction; straight to the point and easy to understand. &lt;br /&gt;
&lt;br /&gt;
•	Your information is organised under appropriate subheadings, making your page easy to read and follow. &lt;br /&gt;
&lt;br /&gt;
•	Your “Types of Male Infertility” table is great! You have provided clear definitions of each condition and the use of colour makes the information stand out. &lt;br /&gt;
&lt;br /&gt;
•	Appropriate referencing throughout.&lt;br /&gt;
&lt;br /&gt;
•	Great audio-visual sources, especially the video. &lt;br /&gt;
&lt;br /&gt;
•	Your page looks even better than a Wikipedia page! A lot of time and effort has gone into it.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''RECOMMENDATIONS'''&lt;br /&gt;
&lt;br /&gt;
•	A glossary at the end of the page would be great, even though you have explained a lot of the concepts in your text. This way the reader does not have to skim through your page to find a term and they can go straight to the glossary.&lt;br /&gt;
&lt;br /&gt;
•	Information under IVF and IUI is absent in “Male Infertility Treatments.” I am not sure if these were meant to be deleted or text will be added later.&lt;br /&gt;
&lt;br /&gt;
It is evident that you have worked fantastically as a team and you have done a lot of research. Each topic is covered comprehensively and aided by a table, image or diagram, making the topic more appealing to the reader. Well done!&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
===4===&lt;br /&gt;
&lt;br /&gt;
The wikipage is very well organised and the headings, subheadings and tables made everything easy to follow. I particularly liked the blue theme you kept with all the tables, it is very aesthetically pleasing. In terms of content the background information provided a clear overview of the subject especially the information about the physiology of fertility in males which laid down the foundation some basic knowledge surrounding male fertility under normal circumstances which I found useful in grasping other concepts throughout the page. The page is filled with an extensive amount of content and along with the long list of references I was given the impression of good understanding of the topic and commendable effort placed into the research.&lt;br /&gt;
&lt;br /&gt;
One thing I found that wasn’t quite compatible with your page was the inclusion of the video in the ‘Causes of infertility section’. Although I do agree that it is a very good video, it had little information surrounding male infertility and was more about infertility in general. Perhaps a video exclusively about male infertility would be more suitable for your page.  &lt;br /&gt;
&lt;br /&gt;
As for some additional improvements, it would be beneficial to include a glossary to explain some difficult terms that would help the audience gain a better understanding of the content. Also, the addition of a hand-drawn image would also be nice. A suggestion would be to exchange your existing ‘components and structure of spermatozoa’ image with a more simplified and schematic diagram of the structure of sperm. &lt;br /&gt;
&lt;br /&gt;
Overall, I enjoyed reading about male infertility and the page is coming together very nicely.&lt;br /&gt;
&lt;br /&gt;
===5===&lt;br /&gt;
&lt;br /&gt;
The introduction is a really important part of the project so it’s important that you get that down. The introduction is well written but it is not done yet as it does not give me a clear idea of the scope of the project. You need to explain the topic in more depth to give readers overall understanding of the male infertility. Maybe think about adding an image to make it a bit more appealing.&lt;br /&gt;
&lt;br /&gt;
Overall this is a well-produced project so far, very impressed. First thing noticeable on the page is the amount of information you have which is great. Only minor changes to polish up some sections are needed which I will explain as we go on. The project as a whole is not text heavy with some good images, tables, diagrams and a short video included which again are helpful in guiding the information. The table in “Diagnosis” section is great and really well done. One thing you could maybe do here is add a few diagrams or images related. I know you have added 2 images down below but I think it’s something that might make it even easier to follow. Try to add more related images to the content of the table. For the “Male infertility disorders”, I believe you can find more information and add to the table as this topic is a big vague and broad. Most of the sections have great amount of detail with a number of in text citations and this is great to see except for the table used in “Male infertility disorders”. Try to fix this up as citations should be carried through the entire page. Other than that, all the citations formatted correctly and it is good that all the references appear in one long list at the end of the page. Well done!&lt;br /&gt;
&lt;br /&gt;
Some sections like “Intrauterine Insemination (IUI)” or “IVF” seems to be untouched. I’m assuming you are still in the process of adding content. However, the “Treatments” section is extensive and well researched. Good job. &lt;br /&gt;
&lt;br /&gt;
To sum up, in terms of improvement, my suggestions are: &lt;br /&gt;
&lt;br /&gt;
•	There is no hand drawn image yet .You may only have 1-2 weeks to complete this project so don’t leave it until last minute.&lt;br /&gt;
&lt;br /&gt;
•	Add more related videos to create the balance.&lt;br /&gt;
&lt;br /&gt;
•	The project could benefit from having a ‘Glossary’ list so that viewers can understand some uncommon words.&lt;br /&gt;
&lt;br /&gt;
•	You have not shown animal model so this can be a potential subheading as well as “future research” or “current research”. Just some tips, when researching on pubmed, there's an option to look at recent articles by customising dates to say 2012-onwards&lt;br /&gt;
&lt;br /&gt;
•	In text-citation &lt;br /&gt;
&lt;br /&gt;
•	Simplify some of your paragraphs into bullet points. This can be done for “Causes of Infertility” or “Treatments”.&lt;br /&gt;
&lt;br /&gt;
•	Finish those untouched topics&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Overall, the project page is interesting, easy to comprehend and follow, however certain changes should be addressed and more information added.&lt;br /&gt;
&lt;br /&gt;
===6===&lt;br /&gt;
&lt;br /&gt;
I’ll begin by commending you on a well contructed wikipage with a great balance of texts and figures. You have used a great variety of supporting resources which complement your text well and aid in the teaching and the understanding of your key points which you have chosen well and mostly covered sufficiently. I particularly liked that you included a graph, (since you are the first project I see with one) and your widespread use of tables which breaks up the text whilst teaching your content well. Good job on being consistent in using the same colour and formatting in your tables. Your explanations are clear and extensive with the main points covered well. Your topic appears to be well research with a thorough list of references and your citations are correct. &lt;br /&gt;
&lt;br /&gt;
While you have included a great table on the types of infertility in males with a brief explanation of each, I feel like this should be elaborated on further. Also, your background information is well written however I feel it is too abrupt. You can include an introductory sentence or paragraph to your subheadings. While it is great that you included a video, I don’t feel like it is relevant to where you have placed it under the causes heading. Since it is more of an overview of infertility in general you can move it to the beginning of the page if you would like to keep it or choose a different video. &lt;br /&gt;
&lt;br /&gt;
While I did say your explanations in general are well written, some areas need more focus, such as your explanation of Varicocele, while you have said that varicocele leads to infertility and explained what is was, it wasn’t clear to me why it causes infertility. Also you should add more significant research beyond the teaching aspect by including some studies conducted and animal models. You can contribute further to the teaching and understanding of your topic by adding your own innovative, drawn diagrams to your great selection of files already added. Just a final formatting point, your images need a higher resolution, most of them are unclear and the words are not very readable. You can edit this by increasing the current 300px resolution to the appropriate pixels. &lt;br /&gt;
&lt;br /&gt;
Great progress overall, good luck with the rest!&lt;br /&gt;
&lt;br /&gt;

The topic is well investigated in this project wiki. It is excellent that you also include some background information on the structure and development of spermatozoa, which would help readers without knowledge in this field.&lt;br /&gt;
&lt;br /&gt;
Images are properly cited and referenced. They make the page looked refreshing. Tables are used wisely to summarize information on ‘male infertility disorders’, but will need some more in-text referencing with the table contents.&lt;br /&gt;
&lt;br /&gt;
Paragraphs are written very well. There are great efforts in rewriting and summarizing. It will be better if the texts can be simplified by some diagrams or lists, which will be easier for readers to get through. Overall, this project wiki is an excellent work.&lt;br /&gt;
&lt;br /&gt;
===8===&lt;br /&gt;
The website is very well organized and contains a lot of researched information and content. The introduction gives a short and precise definition of male infertility and let’s the reader know what to expect from the website. Overall the order of the headings and subheadings is very logical. To start off with explaining the healthy male physiology is a smart way to allow readers with less knowledge about the topic to understand the website. The blue theme of the tables is very coherent and the recurrent incorporation of the tables is alternative to plain text. The “treatment” heading has a lot of information ranging from traditional to Western medicine, which shows that the topic was very well researched. &lt;br /&gt;
&lt;br /&gt;
In addition, it is good to see that at the end of the treatment section (upon completion) the page will give a direct link to ART. The referencing of the website and the images is correct. Here and there are some paragraphs or tables that are not referenced yet (Classifications of Valsalva manoeuvre, Intro. of “Diagnosis”). The amount of references is extensive showing again that the topic has been researched quite well.  The images are very useful, for understanding the content of the website. Particularly the diagrams explaining the Varicocele and the mechanisms of Lycopene Treatment clarify a lot. The timeline of the development of gonadotropin preparations is also a great way to incorporate bits of the history of your topic without spending too much text on it. &lt;br /&gt;
&lt;br /&gt;
It might be useful to add another heading about current research and a glossary to help readers to understand the website. It is really great that you added a video to your website, particularly in the beginning as it will introduce to topic to readers and ease them into the topic. However, it might be reasonable to look for a video that only focuses on male infertility. If that cannot be found it would not be too bad, as the video is still relevant to the topic overall. Moreover, try to add a self-drawn image, maybe in the treatments part for the surgical interventions?.&lt;br /&gt;
&lt;br /&gt;
===9===&lt;br /&gt;
&lt;br /&gt;
Firstly, you have done an exceptionel job in creating such a well organised page with the right amount of images and videos. It is also evident that a lot of effort was taken to make sure each section is covered comprehensively which is a mark of great teamwork. &lt;br /&gt;
&lt;br /&gt;
You have added images and videos at the right places to make it easier for us to absorb the information, however I could not find an original image. Perhaps you could use a flowchart from one of the existing images to make your own simplified version using Word. &lt;br /&gt;
&lt;br /&gt;
The sub-headings are very appropriate and ensure that there are no big blocks of text. My only suggestion would be to cut down on the background information regarding spermatozoa and spermatogenesis. While this is important in providing us with an insight into male reproduction, a paragraph at most would suffice. Under Male Infertility Treatments with ARTs, there are a few sub-sub headings that don't have any text underneath them. &lt;br /&gt;
&lt;br /&gt;
I really liked the use of a table under Risks and Prevention as it breaks the monotonous style of reading paragraphs of text.  &lt;br /&gt;
&lt;br /&gt;
At the end of the page, it would be helpful to include a glossary as there are a few terms that are hard to understand. &lt;br /&gt;
&lt;br /&gt;
I really commend you on being able to produce such a well crafted page that the readers can enjoy going through. Great team work!&lt;br /&gt;
&lt;br /&gt;
===10===&lt;br /&gt;
&lt;br /&gt;
This page is really with high quality. The key points relating to the topic are clearly described. The page is organized very well which is neat and easy to read. The headings and subheadings are appropriate and easy to follow. The video is relative to the content and the images are well chosen. The choice of background color of the tables is pretty good which makes the page nice but still easy to read. The video is well referenced. Other references and citations are appropriate as well. I will make the following suggestions:&lt;br /&gt;
&lt;br /&gt;
1.	A glossary at the end of page will help those without background knowledge understanding the topic easier.&lt;br /&gt;
&lt;br /&gt;
2.	An animal model and the current research may be included in your page.&lt;br /&gt;
&lt;br /&gt;
3.	A hand-drawn image can be added.&lt;br /&gt;
&lt;br /&gt;
Overall, this is a good teamwork and you have made a great page.&lt;br /&gt;
&lt;br /&gt;
===11===&lt;br /&gt;
&lt;br /&gt;
I would like to say great work of find substantial information and images to go along with your wikipage. From the table of contents there seems to be a lot of topics being addressed and with your use of subheadings, it makes navigating the page much easier. The short introduction described the basic meaning of male infertility well as well as the inclusion of some basic statistics is a nice bit of information however it would be nice to have some information regarding what your wikipage will be covering in general&lt;br /&gt;
&lt;br /&gt;
The background information is very useless as it provides the reader with some basic knowledge of where the male reproductive system and its components come into play in regard to the topic of male infertility. The images used are all referenced appropriately and assists in understanding where each component is located and what they look like. The tabulated data of the different types of male infertility allows the readers to easily understand the different kinds and what their relative symptoms are easily. Good job on that! The use of video is nice to see, it has relevance to your topic.&lt;br /&gt;
&lt;br /&gt;
Regarding information within the section ‘Major Causes of Infertility’, the information provided is awesome, however there just seems to be too much information crammed into small paragraphs which makes it quite draining to read. There are many terms which some readers may not know or understand, so I recommend using a glossary to help sort this problem out  maybe simplify the information (if you can)  or break up into more paragraphs to make it easier to read and digest. There are some sections which have no information, however I know that these will be filled by the submission date. The large amount of references is indicative of how much work went into the wikipage for your group! &lt;br /&gt;
&lt;br /&gt;
Good work guys!!&lt;br /&gt;
&lt;br /&gt;
===12===&lt;br /&gt;
&lt;br /&gt;
This group project is so far the most detailed, it has the most information included. Many topics followed by sub topics followed by even more sub topics is a clear indication of the amount of research they have undergone. Multiple diagrams, YouTube videos, flowcharts, microscopic images, histological slides, ultrasonography, timelines and tables were very useful in supporting the information they have and helps give a clear understanding of male infertility. 68 references included a vast search for research they did which is a general indication of reliability so as the multiple citations used throughout the report.&lt;br /&gt;
&lt;br /&gt;
Lack of a glossary doesn’t help the reader as this report is a general but very large topic, with all the information they have included, the readers are bound to come across a fair amount of words or phrases they will not understand. No symptoms are recorded down, and also in the risk factors and prevention section, only one table is included. Perhaps more information regarding the prevention is required.&lt;br /&gt;
&lt;br /&gt;
Overall the project is done quite well, although if a reader was to judge on its clarity they may find it a bit hard as there is a lot of information which could do with a bit of clarity, possibly but separating, bullet points or tables. A glossary should definitely be added as it plays a very important role for the reader’s benefit.&lt;br /&gt;
&lt;br /&gt;
===13===&lt;br /&gt;
&lt;br /&gt;
This Group Project is impressively detailed and provides a comprehensive view of male infertility detailing the normal process as well as the various disorder types and causes. The wikipedia page flows logically, provides excellent summaries and may well be an excellent educational resource. The video chosen is fantastic and tables have been used well to present information quickly.&lt;br /&gt;
&lt;br /&gt;
I find that the Introduction is clear and concise. However, i feel it may be improved further by an introductory visual. Other than that, the page has many relevant diagrams and images. In terms of the 'development of gonadotropin preparations', it does seem a little out of place as it isn't particularly referred to in the text. I understand timelines add a richness to the text and can give perspective, but i feel that it may be of more relevance if given regarding male infertility treatments as a whole, rather than gonadotropin preparations. Of course, you can always have both.&lt;br /&gt;
&lt;br /&gt;
Other than that, I am quite impressed with this wikipedia page. It is referenced well and information is backed with reference to the findings of various studies. A final tip may be to add a simple glossary for ease of reference as opposed to having to scroll back up to the section (e.g. varicocele) to remind oneself of the meaning. However, it should be commended that jargon was defined well throughout the article.&lt;br /&gt;
&lt;br /&gt;
==14==&lt;br /&gt;
&lt;br /&gt;
Great work guys, a lot of information in there.&lt;br /&gt;
Well referenced and easily readable. Nicely broken up with some informative images.  Tables are great and make it easy to find information on a big page. And the first embedded video I’ve seen which is nice.&lt;br /&gt;
Looks like it all the information is there already just a couple of heading to finish off so well done.&lt;br /&gt;
Stylistically the only things ill pick on are,&lt;br /&gt;
The numbered list in treatments, doesn’t fit with the formatting of the rest of the page. Just turn them into subheading or tables like the others. &lt;br /&gt;
Some of the tables are standalone ie. Male infertility disorder that should really have some intro text to them. Also make sure they have a description underneath each one describing what’s in table. And reference of where the information’s coming from.&lt;br /&gt;
You could add a section on epidemiology/prevalence of types of infertility. But the intro could be enough if you flesh something out in there.&lt;br /&gt;
Don’t forget to hyperlink some of the important words to the sites glossary and other pages so people can find extra reading or background. And I think you’ll have a really informative page. &lt;br /&gt;
Fantastic work guys.&lt;br /&gt;
&lt;br /&gt;
===15===&lt;br /&gt;
*The structure of your page is extremely excellent! It flows very well, all headings and subheadings were chosen really well, the use of tables and diagrams are incredible!&lt;br /&gt;
*The heading of “Background information” is VERY extensive, and also concise! The diagram placement is also excellent, and their use is also extremely excellent&lt;br /&gt;
*The use of the video to explain the cause of infertility is absolutely amazing, it makes your page look good, keeps your explanation short, concise, and readable, and it also engages the audience&lt;br /&gt;
*Each subheading under “Causes” is also very well outlined and explained, there is a lot of information there, and it is sure whatever information the reader may need would be found on your page as it has covered and explained a lot&lt;br /&gt;
Overall, all I have for your group are good comments, as I couldn’t think of anything else that you will might need to add or change on it at all! Your information extends beyond what is expected, but also extensive, concise, and, most importantly, extremely readable and engaging! GOOD WORK!&lt;/div&gt;</summary>

&lt;br /&gt;
--[[User:Z8600021|Mark Hill]] ([[User talk:Z8600021|talk]]) 11:20, 25 September 2015 (AEST) OK I discussed this with your group in last week's lab. you have not shown animal models, graphics, histology, media etc to really build your project page. The introduction does not give me a clear idea of the scope of the project. Not ready for peer review.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Hey guys, I have just had a really quick look on PubMed and I found a good starting article. Its a review article (I'm pretty sure) so I'm not sure if we can use it, but it discusses some interesting genetic causes of male infertility and also references a lot of primary articles. &lt;br /&gt;
&lt;br /&gt;
PMID 26178295 &lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
I can't seem to view anything but the first page of the article but the introduction gives a good idea on what male infertility is and how it arises. At the moment I have found 2 research articles that address factors that can increase male fertility. Although they do not address male infertility conditions specifically, in the discussion they imply that these methods can be applied to men who have them such as oligospermia and azoospermia. I feel as though we can use these articles when discussing alternative therapies for successful conception. Please have a read and share your opinions! &lt;br /&gt;
&lt;br /&gt;
PMID 22958644 - note that you can only view the condensed version of this article&lt;br /&gt;
&lt;br /&gt;
PMID 26097523 - you can view the whole article on biomed (subheadings in the discussion particularly addresses male infertility)&lt;br /&gt;

Hey guys, it was pretty hard finding research articles from Pubmed regarding the epidemiology of male infertility.  For now, I have found an article about sperm extraction which I thought could be an alternative for treatments.  However I can't view the full article without paying, but the abstract from Pubmed seems to sum it up.&lt;br /&gt;
So, I came across a research article addressing the epidemiology and aetiology of male infertility, through Pubmed it doesn't have a direct link to the full PDF article however I linked it you guys on Facebook so have a read!&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
Hello everyone! To get started, I just added a few headings on the page where you can add your research/review articles. Feel free to add more subheadings or change the wording of the titles - I'm sure we will need to as we research more. From looking at other groups' pages, I think it is also important we add a bit of 'Background Information&amp;quot; regarding the process of spermatogenesis and how any abnormalities can cause infertility so we can all look for articles as we go. Remember we are targeting this towards students like us, so a bit of key background info is essential. &lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
I just posted the articles that I found on male infertility. It was kind of hard to find ones because I stuck to studies in humans- but i found some good ones that were studies on rats (not sure if we can use them) and also some good secondary or review articles that we could use as background information maybe? So I'll just post the PMID's here..&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
Not sure if we are review articles are any good, but I thought that it's also important to talk about &amp;quot;detecting abnormalities&amp;quot;.  I came across this review article which talks about the &amp;quot;male genital tract - colour dopple ultrasound&amp;quot; is a useful tool to detect impaired reproductive health.&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
Good thinking! If anyone comes across more articles regarding this, please post them up! I'll add a 'diagnosis' sub-heading to the page &lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
Hey guys, found a couple of articles describing different methods of ARTs for male infertility:&lt;br /&gt;
&lt;br /&gt;
These 2 talk about Intrauterine Insemination (IUI)&lt;br /&gt;
PMID 26294874&lt;br /&gt;
PMID 26288981&lt;br /&gt;
&lt;br /&gt;
Also, another potential sub-heading to research might be the risks involved different ARTs&lt;br /&gt;
E.g. the following article about the prevalence of birth defects after a number of different male-related ARTs&lt;br /&gt;
PMID 26265143&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
That sounds good. I think mentioning risks are important to show what is successful and what isnt. Feel free to add it under the &amp;quot;ART&amp;quot; heading (as a sub-heading)&lt;br /&gt;

&lt;br /&gt;
==Peer Assessment==&lt;br /&gt;
&lt;br /&gt;
===1===&lt;br /&gt;
&lt;br /&gt;
To start, I think some of your subheadings are a bit unnecessary, for example, you could get away without having the subheading “background information” and just having the sub-subheadings as subheadings below your intro. Whilst some subheadings are good as it helps break down the info in the table of contents, it makes the actual page difficult to read and follow. &lt;br /&gt;
&lt;br /&gt;
Great use of images on the page. There are many, without it cluttering the page and they are simple and relevant. However, the pictures you have used under “background information” appear to be a bit lifeless and complex. Perhaps using more simplified images with some colours would help liven up the section as well as allow people who use this page, with less scientific knowledge than you, to understand what they are seeing. They are important images as they set the basis for the rest of the page. It would also be good to see a hand-drawn image on the page. &lt;br /&gt;
&lt;br /&gt;
Your use of tables is also great, it really helps to break down the information. I would suggest however, you include a little more information and references under the section “male infertility disorders”. It is a big vague and there are no citations.  Your list of references is incredible and you should be commended on that. It shows a great deal of research has gone into this page. Your citations appear to be correctly done throughout the page. Your “Causes of fertility” section is done really well and is very thorough. The video accompanying it is good to as it is easy to understand and explanatory. Your “risk factors and prevention” heading could use more work. I would suggest actually splitting them up into two separate headings and really delving more into prevention and how to handle infertility. &lt;br /&gt;
&lt;br /&gt;
Your “treatment” section is really well done and thorough. I would suggest however, to make it easier to read, that you simplify some of your paragraphs into bullet points. A glossary section may also be useful for people reading this page with a lesser degree of embryology knowledge than you or I. I will say, this page has covered its chosen topic well and has attacked it from an embryologically focused angle. Lastly I would suggest including a section on animal models and the literature for the more advanced student.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
Very impressive work so far guys! Your page covers a comprehensive topic very well, without focussing too much on certain subheadings at the expense of others. Your use of both tables and images is excellent so far. All necessary copyright information seems to be present for the images that you have uploaded. It's good to see that you have also included a video to give some variety to the media on your page. The 'background information' gives context to the issues which you discuss and though it might not be of great use for someone familiar with embryology, it would be a great help to those with no experience in this field and is therefore useful in establishing the topic of male infertility.&lt;br /&gt;
&lt;br /&gt;
The only things that could be changed to improve your wiki page is perhaps altering the location of tables and pictures on your page. For example all pictures are located on the right side of the page, although not a significant issue, becomes slightly monotonous as one progresses through the page. It may be worth alternating pictures between left and right to mix things up a little bit and improve the overall flow of the page. &lt;br /&gt;
It might also be worth including a short video underneath the 'surgical treatments' subheading to give a visual example of some of the techniques discussed.&lt;br /&gt;
&lt;br /&gt;
Furthermore a subheading on future research could possibly be included under the 'treatments' subheading to give the reader information on techniques and therapies which may come to prominence in the near future.&lt;br /&gt;
&lt;br /&gt;
Your wiki page thus far is very impressive! Excellent work so far.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===3===&lt;br /&gt;
&lt;br /&gt;
Probably the most enjoyable page to read, thus far.&lt;br /&gt;
&lt;br /&gt;
'''COMMENDATIONS'''&lt;br /&gt;
&lt;br /&gt;
•	Great introduction; straight to the point and easy to understand. &lt;br /&gt;
&lt;br /&gt;
•	Your information is organised under appropriate subheadings, making your page easy to read and follow. &lt;br /&gt;
&lt;br /&gt;
•	Your “Types of Male Infertility” table is great! You have provided clear definitions of each condition and the use of colour makes the information stand out. &lt;br /&gt;
&lt;br /&gt;
•	Appropriate referencing throughout.&lt;br /&gt;
&lt;br /&gt;
•	Great audio-visual sources, especially the video. &lt;br /&gt;
&lt;br /&gt;
•	Your page looks even better than a Wikipedia page! A lot of time and effort has gone into it.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''RECOMMENDATIONS'''&lt;br /&gt;
&lt;br /&gt;
•	A glossary at the end of the page would be great, even though you have explained a lot of the concepts in your text. This way the reader does not have to skim through your page to find a term and they can go straight to the glossary.&lt;br /&gt;
&lt;br /&gt;
•	Information under IVF and IUI is absent in “Male Infertility Treatments.” I am not sure if these were meant to be deleted or text will be added later.&lt;br /&gt;
&lt;br /&gt;
It is evident that you have worked fantastically as a team and you have done a lot of research. Each topic is covered comprehensively and aided by a table, image or diagram, making the topic more appealing to the reader. Well done!&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
===4===&lt;br /&gt;
&lt;br /&gt;
The wikipage is very well organised and the headings, subheadings and tables made everything easy to follow. I particularly liked the blue theme you kept with all the tables, it is very aesthetically pleasing. In terms of content the background information provided a clear overview of the subject especially the information about the physiology of fertility in males which laid down the foundation some basic knowledge surrounding male fertility under normal circumstances which I found useful in grasping other concepts throughout the page. The page is filled with an extensive amount of content and along with the long list of references I was given the impression of good understanding of the topic and commendable effort placed into the research.&lt;br /&gt;
&lt;br /&gt;
One thing I found that wasn’t quite compatible with your page was the inclusion of the video in the ‘Causes of infertility section’. Although I do agree that it is a very good video, it had little information surrounding male infertility and was more about infertility in general. Perhaps a video exclusively about male infertility would be more suitable for your page.  &lt;br /&gt;
&lt;br /&gt;
As for some additional improvements, it would be beneficial to include a glossary to explain some difficult terms that would help the audience gain a better understanding of the content. Also, the addition of a hand-drawn image would also be nice. A suggestion would be to exchange your existing ‘components and structure of spermatozoa’ image with a more simplified and schematic diagram of the structure of sperm. &lt;br /&gt;
&lt;br /&gt;
Overall, I enjoyed reading about male infertility and the page is coming together very nicely.&lt;br /&gt;
&lt;br /&gt;
===5===&lt;br /&gt;
&lt;br /&gt;
The introduction is a really important part of the project so it’s important that you get that down. The introduction is well written but it is not done yet as it does not give me a clear idea of the scope of the project. You need to explain the topic in more depth to give readers overall understanding of the male infertility. Maybe think about adding an image to make it a bit more appealing.&lt;br /&gt;
&lt;br /&gt;
Overall this is a well-produced project so far, very impressed. First thing noticeable on the page is the amount of information you have which is great. Only minor changes to polish up some sections are needed which I will explain as we go on. The project as a whole is not text heavy with some good images, tables, diagrams and a short video included which again are helpful in guiding the information. The table in “Diagnosis” section is great and really well done. One thing you could maybe do here is add a few diagrams or images related. I know you have added 2 images down below but I think it’s something that might make it even easier to follow. Try to add more related images to the content of the table. For the “Male infertility disorders”, I believe you can find more information and add to the table as this topic is a big vague and broad. Most of the sections have great amount of detail with a number of in text citations and this is great to see except for the table used in “Male infertility disorders”. Try to fix this up as citations should be carried through the entire page. Other than that, all the citations formatted correctly and it is good that all the references appear in one long list at the end of the page. Well done!&lt;br /&gt;
&lt;br /&gt;
Some sections like “Intrauterine Insemination (IUI)” or “IVF” seems to be untouched. I’m assuming you are still in the process of adding content. However, the “Treatments” section is extensive and well researched. Good job. &lt;br /&gt;
&lt;br /&gt;
To sum up, in terms of improvement, my suggestions are: &lt;br /&gt;
&lt;br /&gt;
•	There is no hand drawn image yet .You may only have 1-2 weeks to complete this project so don’t leave it until last minute.&lt;br /&gt;
&lt;br /&gt;
•	Add more related videos to create the balance.&lt;br /&gt;
&lt;br /&gt;
•	The project could benefit from having a ‘Glossary’ list so that viewers can understand some uncommon words.&lt;br /&gt;
&lt;br /&gt;
•	You have not shown animal model so this can be a potential subheading as well as “future research” or “current research”. Just some tips, when researching on pubmed, there's an option to look at recent articles by customising dates to say 2012-onwards&lt;br /&gt;
&lt;br /&gt;
•	In text-citation &lt;br /&gt;
&lt;br /&gt;
•	Simplify some of your paragraphs into bullet points. This can be done for “Causes of Infertility” or “Treatments”.&lt;br /&gt;
&lt;br /&gt;
•	Finish those untouched topics&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Overall, the project page is interesting, easy to comprehend and follow, however certain changes should be addressed and more information added.&lt;br /&gt;
&lt;br /&gt;
===6===&lt;br /&gt;
&lt;br /&gt;
I’ll begin by commending you on a well contructed wikipage with a great balance of texts and figures. You have used a great variety of supporting resources which complement your text well and aid in the teaching and the understanding of your key points which you have chosen well and mostly covered sufficiently. I particularly liked that you included a graph, (since you are the first project I see with one) and your widespread use of tables which breaks up the text whilst teaching your content well. Good job on being consistent in using the same colour and formatting in your tables. Your explanations are clear and extensive with the main points covered well. Your topic appears to be well research with a thorough list of references and your citations are correct. &lt;br /&gt;
&lt;br /&gt;
While you have included a great table on the types of infertility in males with a brief explanation of each, I feel like this should be elaborated on further. Also, your background information is well written however I feel it is too abrupt. You can include an introductory sentence or paragraph to your subheadings. While it is great that you included a video, I don’t feel like it is relevant to where you have placed it under the causes heading. Since it is more of an overview of infertility in general you can move it to the beginning of the page if you would like to keep it or choose a different video. &lt;br /&gt;
&lt;br /&gt;
While I did say your explanations in general are well written, some areas need more focus, such as your explanation of Varicocele, while you have said that varicocele leads to infertility and explained what is was, it wasn’t clear to me why it causes infertility. Also you should add more significant research beyond the teaching aspect by including some studies conducted and animal models. You can contribute further to the teaching and understanding of your topic by adding your own innovative, drawn diagrams to your great selection of files already added. Just a final formatting point, your images need a higher resolution, most of them are unclear and the words are not very readable. You can edit this by increasing the current 300px resolution to the appropriate pixels. &lt;br /&gt;
&lt;br /&gt;
Great progress overall, good luck with the rest!&lt;br /&gt;
&lt;br /&gt;
===7===&lt;br /&gt;
The topic is well investigated in this project wiki. It is excellent that you also include some background information on the structure and development of spermatozoa, which would help readers without knowledge in this field.&lt;br /&gt;
&lt;br /&gt;
Images are properly cited and referenced. They make the page looked refreshing. Tables are used wisely to summarize information on ‘male infertility disorders’, but will need some more in-text referencing with the table contents.&lt;br /&gt;
&lt;br /&gt;
Paragraphs are written very well. There are great efforts in rewriting and summarizing. It will be better if the texts can be simplified by some diagrams or lists, which will be easier for readers to get through. Overall, this project wiki is an excellent work.&lt;br /&gt;
&lt;br /&gt;
===8===&lt;br /&gt;
The website is very well organized and contains a lot of researched information and content. The introduction gives a short and precise definition of male infertility and let’s the reader know what to expect from the website. Overall the order of the headings and subheadings is very logical. To start off with explaining the healthy male physiology is a smart way to allow readers with less knowledge about the topic to understand the website. The blue theme of the tables is very coherent and the recurrent incorporation of the tables is alternative to plain text. The “treatment” heading has a lot of information ranging from traditional to Western medicine, which shows that the topic was very well researched. &lt;br /&gt;
&lt;br /&gt;
In addition, it is good to see that at the end of the treatment section (upon completion) the page will give a direct link to ART. The referencing of the website and the images is correct. Here and there are some paragraphs or tables that are not referenced yet (Classifications of Valsalva manoeuvre, Intro. of “Diagnosis”). The amount of references is extensive showing again that the topic has been researched quite well.  The images are very useful, for understanding the content of the website. Particularly the diagrams explaining the Varicocele and the mechanisms of Lycopene Treatment clarify a lot. The timeline of the development of gonadotropin preparations is also a great way to incorporate bits of the history of your topic without spending too much text on it. &lt;br /&gt;
&lt;br /&gt;
It might be useful to add another heading about current research and a glossary to help readers to understand the website. It is really great that you added a video to your website, particularly in the beginning as it will introduce to topic to readers and ease them into the topic. However, it might be reasonable to look for a video that only focuses on male infertility. If that cannot be found it would not be too bad, as the video is still relevant to the topic overall. Moreover, try to add a self-drawn image, maybe in the treatments part for the surgical interventions?.&lt;br /&gt;
&lt;br /&gt;
===9===&lt;br /&gt;
&lt;br /&gt;
Firstly, you have done an exceptionel job in creating such a well organised page with the right amount of images and videos. It is also evident that a lot of effort was taken to make sure each section is covered comprehensively which is a mark of great teamwork. &lt;br /&gt;
&lt;br /&gt;
You have added images and videos at the right places to make it easier for us to absorb the information, however I could not find an original image. Perhaps you could use a flowchart from one of the existing images to make your own simplified version using Word. &lt;br /&gt;
&lt;br /&gt;
The sub-headings are very appropriate and ensure that there are no big blocks of text. My only suggestion would be to cut down on the background information regarding spermatozoa and spermatogenesis. While this is important in providing us with an insight into male reproduction, a paragraph at most would suffice. Under Male Infertility Treatments with ARTs, there are a few sub-sub headings that don't have any text underneath them. &lt;br /&gt;
&lt;br /&gt;
I really liked the use of a table under Risks and Prevention as it breaks the monotonous style of reading paragraphs of text.  &lt;br /&gt;
&lt;br /&gt;
At the end of the page, it would be helpful to include a glossary as there are a few terms that are hard to understand. &lt;br /&gt;
&lt;br /&gt;
I really commend you on being able to produce such a well crafted page that the readers can enjoy going through. Great team work!&lt;br /&gt;
&lt;br /&gt;
===10===&lt;br /&gt;
&lt;br /&gt;
This page is really with high quality. The key points relating to the topic are clearly described. The page is organized very well which is neat and easy to read. The headings and subheadings are appropriate and easy to follow. The video is relative to the content and the images are well chosen. The choice of background color of the tables is pretty good which makes the page nice but still easy to read. The video is well referenced. Other references and citations are appropriate as well. I will make the following suggestions:&lt;br /&gt;
&lt;br /&gt;
1.	A glossary at the end of page will help those without background knowledge understanding the topic easier.&lt;br /&gt;
&lt;br /&gt;
2.	An animal model and the current research may be included in your page.&lt;br /&gt;
&lt;br /&gt;
3.	A hand-drawn image can be added.&lt;br /&gt;
&lt;br /&gt;
Overall, this is a good teamwork and you have made a great page.&lt;br /&gt;
&lt;br /&gt;
===11===&lt;br /&gt;
&lt;br /&gt;
I would like to say great work of find substantial information and images to go along with your wikipage. From the table of contents there seems to be a lot of topics being addressed and with your use of subheadings, it makes navigating the page much easier. The short introduction described the basic meaning of male infertility well as well as the inclusion of some basic statistics is a nice bit of information however it would be nice to have some information regarding what your wikipage will be covering in general&lt;br /&gt;
&lt;br /&gt;
The background information is very useless as it provides the reader with some basic knowledge of where the male reproductive system and its components come into play in regard to the topic of male infertility. The images used are all referenced appropriately and assists in understanding where each component is located and what they look like. The tabulated data of the different types of male infertility allows the readers to easily understand the different kinds and what their relative symptoms are easily. Good job on that! The use of video is nice to see, it has relevance to your topic.&lt;br /&gt;
&lt;br /&gt;
Regarding information within the section ‘Major Causes of Infertility’, the information provided is awesome, however there just seems to be too much information crammed into small paragraphs which makes it quite draining to read. There are many terms which some readers may not know or understand, so I recommend using a glossary to help sort this problem out  maybe simplify the information (if you can)  or break up into more paragraphs to make it easier to read and digest. There are some sections which have no information, however I know that these will be filled by the submission date. The large amount of references is indicative of how much work went into the wikipage for your group! &lt;br /&gt;
&lt;br /&gt;
Good work guys!!&lt;br /&gt;
&lt;br /&gt;
===12===&lt;br /&gt;
&lt;br /&gt;
This group project is so far the most detailed, it has the most information included. Many topics followed by sub topics followed by even more sub topics is a clear indication of the amount of research they have undergone. Multiple diagrams, YouTube videos, flowcharts, microscopic images, histological slides, ultrasonography, timelines and tables were very useful in supporting the information they have and helps give a clear understanding of male infertility. 68 references included a vast search for research they did which is a general indication of reliability so as the multiple citations used throughout the report.&lt;br /&gt;
&lt;br /&gt;
Lack of a glossary doesn’t help the reader as this report is a general but very large topic, with all the information they have included, the readers are bound to come across a fair amount of words or phrases they will not understand. No symptoms are recorded down, and also in the risk factors and prevention section, only one table is included. Perhaps more information regarding the prevention is required.&lt;br /&gt;
&lt;br /&gt;
Overall the project is done quite well, although if a reader was to judge on its clarity they may find it a bit hard as there is a lot of information which could do with a bit of clarity, possibly but separating, bullet points or tables. A glossary should definitely be added as it plays a very important role for the reader’s benefit.&lt;br /&gt;
&lt;br /&gt;
===13===&lt;br /&gt;
&lt;br /&gt;
This Group Project is impressively detailed and provides a comprehensive view of male infertility detailing the normal process as well as the various disorder types and causes. The wikipedia page flows logically, provides excellent summaries and may well be an excellent educational resource. The video chosen is fantastic and tables have been used well to present information quickly.&lt;br /&gt;
&lt;br /&gt;
I find that the Introduction is clear and concise. However, i feel it may be improved further by an introductory visual. Other than that, the page has many relevant diagrams and images. In terms of the 'development of gonadotropin preparations', it does seem a little out of place as it isn't particularly referred to in the text. I understand timelines add a richness to the text and can give perspective, but i feel that it may be of more relevance if given regarding male infertility treatments as a whole, rather than gonadotropin preparations. Of course, you can always have both.&lt;br /&gt;
&lt;br /&gt;
Other than that, I am quite impressed with this wikipedia page. It is referenced well and information is backed with reference to the findings of various studies. A final tip may be to add a simple glossary for ease of reference as opposed to having to scroll back up to the section (e.g. varicocele) to remind oneself of the meaning. However, it should be commended that jargon was defined well throughout the article.&lt;br /&gt;
&lt;br /&gt;
==14==&lt;br /&gt;
&lt;br /&gt;
Great work guys, a lot of information in there.&lt;br /&gt;
Well referenced and easily readable. Nicely broken up with some informative images.  Tables are great and make it easy to find information on a big page. And the first embedded video I’ve seen which is nice.&lt;br /&gt;
Looks like it all the information is there already just a couple of heading to finish off so well done.&lt;br /&gt;
Stylistically the only things ill pick on are,&lt;br /&gt;
The numbered list in treatments, doesn’t fit with the formatting of the rest of the page. Just turn them into subheading or tables like the others. &lt;br /&gt;
Some of the tables are standalone ie. Male infertility disorder that should really have some intro text to them. Also make sure they have a description underneath each one describing what’s in table. And reference of where the information’s coming from.&lt;br /&gt;
You could add a section on epidemiology/prevalence of types of infertility. But the intro could be enough if you flesh something out in there.&lt;br /&gt;
Don’t forget to hyperlink some of the important words to the sites glossary and other pages so people can find extra reading or background. And I think you’ll have a really informative page. &lt;br /&gt;
Fantastic work guys.&lt;br /&gt;
&lt;br /&gt;
==15==&lt;br /&gt;
*The structure of your page is extremely excellent! It flows very well, all headings and subheadings were chosen really well, the use of tables and diagrams are incredible!&lt;br /&gt;
*The heading of “Background information” is VERY extensive, and also concise! The diagram placement is also excellent, and their use is also extremely excellent&lt;br /&gt;
*The use of the video to explain the cause of infertility is absolutely amazing, it makes your page look good, keeps your explanation short, concise, and readable, and it also engages the audience&lt;br /&gt;
*Each subheading under “Causes” is also very well outlined and explained, there is a lot of information there, and it is sure whatever information the reader may need would be found on your page as it has covered and explained a lot&lt;br /&gt;
Overall, all I have for your group are good comments, as I couldn’t think of anything else that you will might need to add or change on it at all! Your information extends beyond what is expected, but also extensive, concise, and, most importantly, extremely readable and engaging! GOOD WORK!&lt;/div&gt;</summary>

&lt;br /&gt;
--[[User:Z8600021|Mark Hill]] ([[User talk:Z8600021|talk]]) 11:16, 25 September 2015 (AEST) Hmm still a little thin. There should be some animal model info, histology images, physiological data, drug info, and genetic information.&lt;br /&gt;
&lt;br /&gt;
--[[User:Z3374116|Z3374116]] ([[User talk:Z3374116|talk]]) 17:15, 18 August 2015 (AEST) Hello there&lt;br /&gt;

--[[User:Z3415911|Z3415911]] ([[User talk:Z3415911|talk]]) 16:12, 24 August 2015 (AEST) Hey guys! So I've gone and added a few subheadings that may be useful to start researching. For this weeks assessment we need to choose one each and find 3 articles to go with it etc. So if we all choose one and start researching it, that would be good :)&lt;br /&gt;

--[[User:Z3374116|Z3374116]] ([[User talk:Z3374116|talk]]) 12:07, 28 August 2015 (AEST) I was thinking to include the risk factors in the 'causative' subheading&lt;br /&gt;

--[[User:Z3374116|Z3374116]] ([[User talk:Z3374116|talk]]) 13:22, 28 August 2015 (AEST) So basically in the Causative subheading, I was planning&lt;br /&gt;
1) Identify the different causes (including primary and secondary risk factors)&lt;br /&gt;
2) What difference occurs from a normal cycle (e.g. level of hCG normally)&lt;br /&gt;

--[[User:Z3415911|Z3415911]] ([[User talk:Z3415911|talk]]) 13:36, 28 August 2015 (AEST) No problem! I hope your cousin is okay. Whoever added a sub heading called: Tests and Diagnosis, there already is the same kind of subheading, Symptoms and Diagnosis so we need to merge the two. It also needs to be in chronological order&lt;br /&gt;
&lt;br /&gt;
--[[User:Z3372824|Z3372824]] ([[User talk:Z3372824|talk]]) 13:46, 28 August 2015 (AEST)Hope he gets well! Talking about sections, I'll try and work on Prevention, and get the research summaries done for that section by next week.&lt;br /&gt;

--[[User:Z3372824|Z3372824]] ([[User talk:Z3372824|talk]]) 14:00, 28 August 2015 (AEST) J and I had a little discussion about how we're going to go about completing this. We can all work on each others sections and collaborate that way. Let's focus on finding research articles, collating them, referencing them i.e. get to the meat of the matter. Once we've done that we can cut to the point and make it more easy-to-read/user-friendly. We also think that our 1 wiki page reference should be the OHSS Wiki page. Also, when writing about your section, always compare/refer to the Controlled Ovarian Stimulation case. Bring those picture/youtube suggestions in!&lt;br /&gt;
&lt;br /&gt;
--[[User:Z3374116|Z3374116]] ([[User talk:Z3374116|talk]]) 00:12, 29 August 2015 (AEST) Sweet, thanks for the info. Will be on the lookout for youtube clips and pictures. Is the OHSS wikipage you are referring to https://en.wikipedia.org/wiki/Ovarian_hyperstimulation_syndrome&lt;br /&gt;
this one?? And I agree on helping each other with respective sections and then cutting it down to the fine details&lt;br /&gt;

--[[User:Z3415911|Z3415911]] ([[User talk:Z3415911|talk]]) 21:49, 1 September 2015 (AEST) Yes, that's the wiki page :) I have already started taking down information from it in each section so when you see '''[OHSS Wiki]''', that's where the information is from. I just don't know how to reference something that is not pubmed yet haha&lt;br /&gt;

==Peer Review==&lt;br /&gt;
&lt;br /&gt;
This wikipage is very well put together. Your choice of headings, subheadings and tables and images is remarkable, it definitely makes the whole page flow very well. I particularly like the hand-drawn image which does a great job at simplifying the process of the pathogenesis of OHSS. &lt;br /&gt;
&lt;br /&gt;
The introduction very concisely explains the contents of the page and I liked how it was finished off with a statement about the aim of the page. I thought it really brought the introduction together nicely. I can’t say much about the content except that it is very engaging and very well written so well done guys! Keep up the good work!&lt;br /&gt;
&lt;br /&gt;
Some suggestions I have that could improve your page include adding more images. It would be nice to have some graphs to complement the statistical date from the epidemiology. Also, in some of the paragraphs e.g. in the last paragraph of ‘Epidemiology’ there isn’t a citation that accounts for the information at the end of the paragraph so that should be fixed. &lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
This page clearly and efficiently explains the topic of choice. It covers all relevant matters well and the text is descriptive and informative. After reading the page, I felt as though I had a greater understanding of the topic. The subheadings used are good, and are placed appropriately in order - providing an element of cohesiveness between the page and the topic in general. Good use of linking statements – connecting all the elements discussed on the page. &lt;br /&gt;
&lt;br /&gt;
There is however an excessive amount of text used. Although the information is relevant and informative, the page is dense and reading all at once is tiresome. Reducing/sifting through the amount of text on the page – and also adding a great deal more media files will help to break up the denseness of the page. There is only 1 image on the whole page – greater attention needs to be paid to alternative media files and sources to help break up the page. Additional media files will also add to increasing the understanding of readers. &lt;br /&gt;
	The diagram drawn is neat and cited correctly. --[[User:Z5015534|Z5015534]] ([[User talk:Z5015534|talk]]) 15:07, 13 October 2015 (AEDT)&lt;br /&gt;

This Wiki covers the topic well. The content is very well written and easy to understand.  Images and texts are correctly cited and referenced. In some of the sections, eg, ‘Ovulation Induction’, ‘Avoiding hCG during Luteal Phase Support’, more in-text reference will need to be added.&lt;br /&gt;
&lt;br /&gt;
It is a great idea to have some bold texts in lines, which highlight the main points of paragraphs, and help readers to understand when skimming.&lt;br /&gt;
&lt;br /&gt;
The hand-draw diagram of ‘pathogenesis of OHSS’ is excellent. It is well structured, and easy to understand and memorize.  It will be great if more images, diagrams, videos can be added to the other sections.&lt;br /&gt;
&lt;br /&gt;
Overall, the project page is very well developed. Some of the sections need to have more work on though. It would be nice if more graphs and tables can be added to balance the texts.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
So far your wiki page gives a very good coverage of Ovarian Hyper-Stimulation Syndrome. The progression of your subheadings progresses logically from one topic to another. It's good to see that you've included an excellent hand-drawn image which is well suited to the 'pathophysiology' subheading. The amount of textual information you have under each heading is vast and gives a comprehensive description of OHSS. Furthermore, you have an excellent range of sources to support your discussion.&lt;br /&gt;
&lt;br /&gt;
I feel however that asides from your hand-drawn image, your use of images and other source of media is definitely lacking. As is, your page is largely text with little to no breaks, making it quite difficult to read. The use of images would not only help break up the monotony of the text, but also help reinforce some of your ideas. I feel that the inclusion of images in the 'symptoms' and 'complications' subheadings would be suitable. &lt;br /&gt;
&lt;br /&gt;
It may also be worthwhile to include subheadings concerning current research, to inform readers about contemporary developments regarding OHSS. Furthermore,  'future research' could also be another potential subheading and could illuminate potential areas that are beginning to be or could be investigated in coming years.&lt;br /&gt;
&lt;br /&gt;
Overall, a very impressive page so far, that could be enhanced with the addition of relevant images and other media.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
Great work, it looks like your group has a clear mindset and direction to where your group project is going, even if it is not there yet. Also great introduction! Your entire page's contents were introduced well and simple. However, all Text and no images were included except one image. Not a good look to go through. The information here is good but is also very dense and hard to follow without any images. It would be great if you could break it up a bit with more images, tables, diagrams and hand drawn pictures. This style of writing is very professional and would be perfect for a report or essay; however as a wiki page it is too hard to follow. Breaking up the information into tables and short videos would allow you to guide the reader through your topic.  Well done on the use of bullet points make it easy to follow. Only one hand drawn image as well as one table uploaded onto the page contains adequate information explaining them, which is good. &lt;br /&gt;
&lt;br /&gt;
Well done on use of “Glossary” section. It is indeed necessary and important. &lt;br /&gt;
&lt;br /&gt;
There has clearly been a lot of research and work put into this project and that is very commendable and I do appreciate it. However on a whole as I mentioned, there is too much information without having any interactive techniques such as tables, diagrams and etc. One of my suggestions is to make a table for “Prevention” or “Genetics” section or even both. I also suggest adding another subheading for “current research findings” or “Future research” which requires more time and research. Therefore you can include more journal articles in this section .In this section pictures would also be good to help understand and engage readers. Overall,  well done on your written information for each section. They’re very relevant to the topic and to the project as well.&lt;br /&gt;
&lt;br /&gt;
Some sections like “Effect on the Newborn” or “Animal Models” seem to be untouched. I’m assuming you are still in the process of adding content. Please be aware of the deadline. Moreover, in text citation is crucial which are missing in some paragraphs. Citations should be carried through the entire page to know exactly where you have got your information from. Good job on referencing at the end of the page. All research articles seem to be relevant to all sections.&lt;br /&gt;
&lt;br /&gt;
Overall, it is a really good project with the potential to be excellent because of the amount of effort you have put into the research. Keep up the good work, but just edit and add those things I mentioned to the project and finish the sections you need to. Very well done so far and good luck with finishing the project off.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
I found your topic very intriguing! It appears as though you have put a lot of time into researching your area and ensuring that your have addressed the main concepts. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''COMMENDATIONS'''&lt;br /&gt;
&lt;br /&gt;
•	Fantastic introduction! It gave me a clear overview of what your group’s topic is, and it was easy to understand. &lt;br /&gt;
&lt;br /&gt;
•	Great overview of the symptoms. Your table added some colour to the page and the information was succinct. &lt;br /&gt;
&lt;br /&gt;
•	You are to be commended on your hand drawn image - very clear and neat. Good job! &lt;br /&gt;
&lt;br /&gt;
•	Clear reference list and good in text citations.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''RECOMMENDATIONS'''&lt;br /&gt;
&lt;br /&gt;
•	A map in the Epidemiology section would put your text into perspective for the reader. &lt;br /&gt;
&lt;br /&gt;
•	Some words have been typed in bold (particularly in the Diagnosis section). The selected words seem to be a bit random. Maybe you could highlight phrases rather than words, or organise the information under subheadings. &lt;br /&gt;
&lt;br /&gt;
•	More images would break up the information and aid the reader’s understanding of the given concepts. Subheadings would also help organise the information to place ease on reading and comprehension. &lt;br /&gt;
&lt;br /&gt;
•	Your page features large chunks of text for the most part. I would recommend reading through your text and removing excessive bits of information; try and be a bit more succinct. You could use more tables and diagrams to communicate certain concepts as well (e.g. Treatment and Diagnosis). &lt;br /&gt;
&lt;br /&gt;
•	Information is absent under “Animal Models” and “Effect on the Newborn.”&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
With this said, your group has covered all the key concepts and it is evident that you have done a lot of in depth research. You are definitely on the right track. &lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
Collectively, this page is well structured and shows you have a well-rounded understanding of this topic. The introduction encapsulates the whole topic extremely well and provides a good framework for the rest of the page. The headings are relevant and follow the structure to discuss a disease, thus being very easy for the reader to grasp the key concepts of the syndrome. Perhaps consider using bullet points in your “Causative Agents” section and “Prevention” heading. You can also utilize numerical steps to describe the pathogenesis of OHSS to accompany the well-structured diagram, and to break up the text in your page. &lt;br /&gt;
&lt;br /&gt;
I have also noticed that the page is lacking subheadings in a few sections, thus it prevents the reader from knowing the key points that are being discussed and explained. Together with the subheadings that are already present, they can also be used under “Diagnosis” for each diagnostic tool, “Genetics” for VEGF, LHR and BMP-15, and possibly in the “Animal Models” section. The content under each of these headings however, is very interesting and has been written well, showing you have gained a thorough understanding of OHSS. I am certain the content you add for the untouched headings will also be of a high standard. On that note, further explanation about treatments and complications of OHSS could be added. These sections are currently lists therefore they can be further expanded with more research and videos to explain things like surgery procedures. &lt;br /&gt;
&lt;br /&gt;
The glossary provided is extremely beneficial however; more diagrams, tables, and videos should be incorporated to further enhance the reader’s understanding. At the moment it is quite content heavy and needs visual aids to make the page more interesting and easy to read. &lt;br /&gt;
&lt;br /&gt;
This page also demonstrates that you have thoroughly researched each aspect of OHSS, and have used recent studies to support the content added. The resources have all been cited correctly, but perhaps search for more literature to further support your claims and theory regarding OHSS. &lt;br /&gt;
&lt;br /&gt;
I am really impressed with your page so far. Using more references, visual aids, and adjusting the format of this page will guarantee a successful mark. Well done! &lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
I’d like to start by commending you on an exceptional choice of key points which you have chosen to research and elaborate on. They provide a good overview of the subject for your readers. They are clearly explained and taught at a peer level without dragging on with irrelevant points. Your introduction is well written, I especially like that you have included the aim of you wikipage in the introduction and the key points you will be focusing on to orient your reader. Including epidemiology was also a good choice as it shows the relevance and impact of Ovarian-stimulation syndrome in society. I also find that including prevention and treatment is great for visitors without an embryology background who are looking for general information on the topic, especially for women who can learn to better reduce their risk since this page is accessible to the public. &lt;br /&gt;
&lt;br /&gt;
Other great aspects of your page include the inclusion of a glossary for readers to refer to when they are unclear on the terminology and that you have used relevant sources. The table used to organize the symptoms makes its easy to read and understand. I particularly liked your section on the pathophysiology. Not only is it explained well but you have included a great hand drawn diagram that is clearly drawn, complements the adjacent paragraphs well and includes a statement with permission to other visitors to reuse it. &lt;br /&gt;
&lt;br /&gt;
Going forward your main focus’ should be conducting further research to complete your remaining key points on the effects on the Newborn and animal models (very relevant for embryology peers). Also, focus on including more supporting diagrams and figures since so far you only have one. A histological image of the ovaries would be very appropriate to your topic. Make sure you read over your page to edit your grammar and wording for example in the phrase “they are given to assistive medication”. Your citing is well done, but make sure when you are referencing websites that you include the retrieval date such as in reference 11. &lt;br /&gt;
&lt;br /&gt;
Overall your page is well written, with my main concern being is it sounds more like a report than a peer teaching page. You can fix this by adding more images, diagrams, figures and tables to break up the text and help to explain your content. Adding a video would also be engaging. Otherwise, great progress so far! &lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
Everyone seems to have already commented on your introduction, but it will not deter me from giving you another amazing high five! That introduction is so well thought out and structured that it has set up the entire page in an easy to read and easy to understand way- amazing work!! The page as a whole was fantastically structured and I found it very easy to follow which made the experience of reading and learning about the topic. Furthermore the topic was outstandingly researched with a wide variety of sources and really demonstrated the time and effort that you guys have put into it so great job; however, one thing that lets you down here is that there are some citations missing or large chunks of writing that are not cited which is a shame because it is evident that you have put in the time and effort. The language that has been used through out the page, although very formal, was appropriate and made it easy to understand the information. This was further aided by the inclusion of the glossary which is a necessity and was very well planned. I also really enjoyed the inclusion of the section &amp;quot;Epidemiology&amp;quot; as it provided a comprehensive snap shot and scope of the disease. &lt;br /&gt;
&lt;br /&gt;
Some aspects that you could improve on include the inclusion of more images, videos, graphs and tables. Again, everyone seems to have commented on this, there is too much writing and it makes it difficult to follow and stay concentrated on the information. Another point to improve on would be further explanations about the treatment and prevention, this would be highly beneficial as it not only would provide information to students but also relevant and useful information to the public as the site is public facing. Lastly, the information missing below the “Effect on the Newborn” and “Animal Models” section will add another layer of detail and ultimately complete the page. &lt;br /&gt;
&lt;br /&gt;
Overall, you guys have done an amazing job- the main area of improvement is the inclusion of more interactive and visual elements that can break up the chunks of texts and make the page more well-rounded. Awesome work and I look forward to seeing the end result!!&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
This Wikipage is very well structured, the headings and subheadings are all very appropriate; the introduction presents the entire topic very well.  This really grabs the attention of the audience as the structure of the page is very easy to navigate.  “Epidemiology” was very easy to understand as you introduced all the jargon with its shortened name; good idea to add the glossary at the bottom defining all the scientific terms. It is very beneficial for those audience who have not been introduced to these scientific terms.  “Causative Agents” was explained perfectly, which makes it easier for the audience to read. I also suggest using some bullet points and tables.  It’s great to see the use of tables in “Symptoms”, it simplifies the content and makes it easier to categorise the different severity of the symptoms.  As for “Diagnosis”, I suggest adding some subheading to separate the different ways of diagnosis (History, physical examination, ultrasound, further investigations etc).  Make sure you add more subheading throughout the page, it highlights the key points for each heading for the audience.  “Complications”, “Treatment” and “Prevention” has good use to subheadings, it is well structured and interesting to read.  This shows that you have conducted adequate literature searches and have a deep understanding of OHSS.  I suggest to add more information into complication, case studies or examples could be used.&lt;br /&gt;
&lt;br /&gt;
I am impressed to see that you guys have drawn your own detailed diagram.  However, I suggest that you add more diagrams, videos and tables; this can enhance the audience’s understanding towards OHSS.  There is a lot content at this point which is great to see all the research you guys have conducted however, it need visual aids to make the page easier and more interesting to read.  All the resources have been cited correctly but I think more research to support the page and enhance the validity of your information.&lt;br /&gt;
&lt;br /&gt;
Overall, I am very happy with this page.  Remember, more visual aids (diagrams, videos, tables and flowcharts).  Great work!&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
The contents of the website about OHSS appear to be very well researched and the key points of the topic are clearly described. The headings and subheadings are in a logical and complete order. However, it might be useful to add a new heading labelled “Current Research” about e.g. the pathophysiology, treatments, diagnosis, etc. It might be that this will  be included in the “animal models” section, which is still incomplete. Upon completion of the last sections it might be useful to round the website off with a conclusion. &lt;br /&gt;
&lt;br /&gt;
The website so far has only one image. However, the image is self-drawn and very clear. The image is useful, readable, and makes the understanding of the pathophysiological processes easier. It might be good to consider adding more graphs and images to the website. Useful images could display the involved anatomical structures, the symptoms, and the diagnostic procedures (Ultra-sound showing OHSS).&lt;br /&gt;
&lt;br /&gt;
The used references are all very recent, which strengthens the credibility of the website. However, sometimes sentences or paragraphs are not cited at all. Thus, lacking citations should be added. The glossary is a nice addition to the website but still needs to be completed (VEGF, LHR, BMP-15, etc.)&lt;br /&gt;
&lt;br /&gt;
It might be beneficial if the link to ART were explained more clearly. As the general frame of the project is ART, including OHSS’ implications on the procedure, causative role, etc. would elucidate that link.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
The structure of your page is very effective in allowing us to easily understand the topic. The introduction is brilliant as it focuses on the main points of the topic while touching on a bit of its history and then finally stating the purpose of the page. &lt;br /&gt;
&lt;br /&gt;
The hand drawn image is outstanding and presents the information in a very appealing way. As there is only one image so far, it would be great if you could include more images, especially for sections such as epidemiology and causative agents. For diagnosis, you could include an image of an ultrasound or X-ray which would give us a better understanding of the physical changes that are seen as a result of this problem. &lt;br /&gt;
&lt;br /&gt;
I love the use of bold text to highlight the important features of some sections. It would be great if this is used in the other sections too as it really helps to focus on the main points. &lt;br /&gt;
&lt;br /&gt;
The use of a table to present the symptoms is a great idea. It would be great if this was also done for treatments which is also divided into sections of mild, moderate and severe. &lt;br /&gt;
&lt;br /&gt;
It's evident that a lot of research has been done to finding the information on this topic, however I feel that for some sections, there might be a bit too much information, particularly for Prevention and Genetics. If possible, try and make these sections more concise by focusing on the main points. For genetics, it might be helpful to have a sub-sub heading for each new growth factor or receptor discussed. &lt;br /&gt;
&lt;br /&gt;
Overall, I think you guys have done an amazing job with this page. Apart from the minor changes here and there, there is not much more to be done. Great job!&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
First of all, I’d like to say this is a fantastic wiki page. The key points for polycystic ovarian syndrome are well described. The page is well structured and the layout is clear and easy to follow. Making	each section expandable is a good idea. The bold texts in lines highlight help readers catching the main points easier. One of the highlights of this page is the introductory. It is well written and the aim of the page gives reader an overview and a general idea of this page. The table and image used are relative to the topic. The background color of the table is pretty nice and the content in the table is still easy to read. The glossary at the end of page helps those without background knowledge understanding the topic easier. The references and citations are appropriate as well as the text citations. Some recommendations I will give will be:&lt;br /&gt;
&lt;br /&gt;
1.	More images and videos may be used so that the page is easier to read.&lt;br /&gt;
&lt;br /&gt;
2.	Recent research may be included in your page.&lt;br /&gt;
&lt;br /&gt;
Overall, you have done a fantastic job. Thanks for your effort.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
Great project so far, it is well structured and easy to read. the headings make sense and flow easily form one to the next.  You introduction is really nice and the stated purpose at the bottom as well as a brief historical context really and depth and context to the assignment. your have also used of dot points and bold to highlight key points within the text which is very effective.  Your hand drawn image is clear and concise, it is also correctly cited as well good job!&lt;br /&gt;
&lt;br /&gt;
There is not much more that  I would recommend for this web page, as the content is very relevant. I recommend trying to use some more references, they are valid and useful but most of the other groups have nearly double the resources and references that you guys do, perhaps a good target would be more than 1 citation per paragraph. &lt;br /&gt;
&lt;br /&gt;
Also  more images could be used as you page is very content heavy, but you could use more images, a video and perhaps even a Graph to break up the information.  under the Causative agent subheading  perhaps you could make reference to pituitary action as well as the  anterior pituitary  and provide a flow chart of diagram, there are many excellent diagrams displaying this process that could be incorporated here- look into text books. &lt;br /&gt;
The animal models would be as awesome addition to you webpage and there will be a huge range of awesome images that you will be able to use and  maybe incorporate current research in the field subheading and find some information of current studies being conducted ect. Great use of the glossary but more terms need to be added to the list. Also you have a lot of physiology and pathology content - which is fantastic perhaps you may  try to relate it back to ART and IVF more as well as maybe including abnormalities and effects of the development and birth of the child. &lt;br /&gt;
&lt;br /&gt;
On the whole, this is an awesome project, and there isn't much more to do to complete it. Great Job guys&lt;br /&gt;
----&lt;br /&gt;
Great stuff guys, &lt;br /&gt;
Good layout, nice flow of topics and comprehensive. Language is easy to follow. Well research and supported. There are couple of parts that need some references WIKI original recommends that if you make a statement of fact or something that can be disputed you should add a reference ie. last statement of epidemiology . But, work in progress, i understand. &lt;br /&gt;
You could hyperlink some of the more unfamiliar words to the UNSW embryology glossary and other pages to get the wiki &amp;quot;click through&amp;quot; effect. I hate to recommend it because i really like how clean and &amp;quot;wiki&amp;quot; like your page is but we have to add images so perhaps a map of the genes and mutations, show the promoters and such?&lt;br /&gt;
The symptoms section has some repetition to its structure i think you should condense it all into the table then write a lead in paragraph to the table. Lead in could have a bit about when the symptoms usually come on in life? I would recommend moving diagnosis to above treatment and after pathology to help with flow. This would also semi-separate the page into theory and clinical.&lt;br /&gt;
For the pathology image if you make a one by one table and put the image into it, it should sit in alignment on the page. Its just my browser but on a smaller screen it cuts out to the left. Not a big deal. try to have the images on a line to them selves or at the end of paragraphs rather then word wrapping the text. Makes it look neater no matter how big you have the window. &lt;br /&gt;
That's all i can think of. Other wise looks like it going to be one of the best of the class. Very professional.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
The topic of OHSS was outlined very well, with very good choice of headings, separating the different key points and areas that you’ve discussed on your page. It’s evident you’ve done extensive research on your topic, and all your information is very concise and very readable. You’ve also extended your topic beyond the general symptoms, diagnosis, causes etc like “animal models” “effect on the newborn”, it is very extensive!&lt;br /&gt;
&amp;lt;b&amp;gt;Pros&amp;lt;/b&amp;gt;&lt;br /&gt;
*Extensive research evident, a lot of information is provided&lt;br /&gt;
*Introduction is short and concise, but also extremely informative, highlighting the aim of the page as well!&lt;br /&gt;
*Statistics of the disease is also given, numerical data is always good&lt;br /&gt;
*Good use of a table in “Symptoms”, making it very readable and engaging&lt;br /&gt;
*The presence and position of the drawing in “Pathophysiology” is prenominal, you’ve gone out of your way to draw a diagram to illustrate the topic&lt;br /&gt;
*Good use of bullet points in “Treatment”, very concise and readable and there isn’t a jumble of words&lt;br /&gt;
&amp;lt;b&amp;gt;Cons&amp;lt;/b&amp;gt;&lt;br /&gt;
*A photo or video in your introduction could be used to illustrate what the topic is better&lt;br /&gt;
*There’s a lot of technical jargon already in your introduction, words like neoangiogenesis and iatrogenic. Readers who come to your page may not necessarily understand those words. These words can be defined in your glossary, but readers read in logical flow, they won’t scroll all the way to the bottom of your page because they didn’t understand the word to find the meaning then come back to the introduction to continue. These words don’t have to be replaced, but an explanation might ease your cause&lt;br /&gt;
*A graph or table or pie chart representing epidemiology will make the heading more informative&lt;br /&gt;
*Photos showing symptoms will substantially help, especially when they’re separated into mild, moderate, and sever.&lt;br /&gt;
*Diagnosis needs to be expanded more. The bold type words should be made into subheadings so you can expand on each more, defining how and why they are performed&lt;br /&gt;
*Headings of “effect on the newborn” and “animal models” need to be completed&lt;br /&gt;
*You have a lot of information on your page but only a few are referenced, a lot more in text referencing and references are needed for the amount of information you have&lt;/div&gt;</summary>

==Mitochondria==&lt;br /&gt;
*discovered in muscle by Kölliker in 1857&lt;br /&gt;
*mitochondria are the &amp;quot;powerhouses&amp;quot; of the cell and the location where respiration occurs at the cellular level.&lt;br /&gt;
*mitochondria contain their own DNA (mitochondrial DNA or mtDNA) that has been originally inherited only from the oocyte (maternal inheritance).&lt;br /&gt;
*The spermatozoa (paternal) mitochondria- energy for fertilization motility but are generally destroyed during the first mitotic cell divisions. &lt;br /&gt;
*This pattern of inheritance has important implications for a variety of mitochondrial associated diseases, usually occurring in tissues requiring lots of energy (muscle, brain). &lt;br /&gt;

&lt;br /&gt;
--[[User:Z8600021|Mark Hill]] ([[User talk:Z8600021|talk]]) 16:07, 21 August 2015 (AEST) I think you will have 3 students and therefore will exist as a group.&lt;br /&gt;

I will definitely be back next week. I have added few sub-headings to the points you guys setup, feel free to change them. BTW, would you like to pick one of the 5 topics for now? and start working on it? or there was some good arrangement already? please let me know.&lt;br /&gt;
&lt;br /&gt;
--[[User:Z3292373|Z3292373]] ([[User talk:Z3292373|talk]]) 20:51, 24 August 2015 (AEST) Hey, ummm sorry i lead us astray putting up those headings ''female fertility'' had been taken so we have to pick another. I put up the list of ones left. My choice would be three parent ivf. So ill do a bit of research and on that now (add some headings)just 'cuase i got some free time, but by all means if you guys would like to do something else that interests you I'm more then happy to change. &lt;br /&gt;

==Peer Reviews==&lt;br /&gt;
&lt;br /&gt;
===1===&lt;br /&gt;
This wiki page does well in covering a lot of areas relating to the topic, however the website does not outline the information found/used quite clear enough or to the right extent. The page would benefit largely in focusing much more attention to the mechanics of the process itself and how it physically works. There is lots of information regarding other various aspects relating to the topic, however the fundamentals of the topic are not clearly discussed on the page, and it is not clear what goes on in the process. &lt;br /&gt;
&lt;br /&gt;
The page should also fix up some grammatical and syntax errors. Read through the page carefully and ensure all paragraphs make sense ensuring that the quality of the information portrayed is fully appreciated. To also make the page clearer, some thought should be given to rethinking the order of the subheadings. Having a natural cohesion throughout the page as a whole is important – some subheadings do not fit into place correctly and could be moved around a little bit. Also having linking sentences within paragraphs – involving each subheading with others and the topic as a whole – will  make the page much more cohesive. &lt;br /&gt;
&lt;br /&gt;
The page used a good amount of supporting pubmed articles, hwoever more images/media files could be used to break up the concentrated use of text. The video used is relevant and informative – however there is no copyright information.--[[User:Z5015534|Z5015534]] ([[User talk:Z5015534|talk]]) 22:44, 10 October 2015 (AEDT)&lt;br /&gt;
&lt;br /&gt;
===2===&lt;br /&gt;
Hi guys! I'll start of by saying that the images and video you have included are excellent and are relevant to your topic of discussion. Also, you have a large number of reliable references which is good to see. However you have yet to include a hand drawn image, which is required for the wiki page. I feel like  you could probably eliminate the typed out 'timeline of mitochondrial donation' and instead use this as an opportunity to use a hand drawn image of the timeline. Furthermore, the timeline under 'cystoplasmic transfer' feels a bit awkward and unnecessary. You could probably include this timeline alongside the 'timeline of mitochondrial donation'. &lt;br /&gt;
&lt;br /&gt;
Under the 'Technical Progression' section it would be best to incorporate human embryo, mouse and human models under a sub-sub heading, as at the moment it feels a bit jumbled.&lt;br /&gt;
&lt;br /&gt;
I would also recommend moving the 'Benefits' heading towards the end of the page. It feels odd reading about the benefits of three person embryos before I gain a proper understanding of how they work. Also it might be worth talking about the disadvantages (if there are any) to three person embryos to balance out the 'benefits' section. As has been previously stated, make sure you sort out the copyright information for your video as it would be a shame to lose marks if it was missing. Also, don't forget to add the 'student template' to the 'Swapping mitochondrial DNA mammalian oocytes' image as it is currently absent.&lt;br /&gt;
&lt;br /&gt;
===3===&lt;br /&gt;
The entire project is presented simplistically and all the content is relevant and easy to understand. Majority of the flaws I found were based around poor grammar and syntax which could be fixed up with some editing. Below is a more detailed breakdown of some of the things you could fix.  &lt;br /&gt;
&lt;br /&gt;
Firstly, I liked that the introduction was brief and concise and gives the reader a basic understanding of the topic of three person embryo. The video was also informative and provided some background information around the topic. I was informed that mitochondrial DNA was the major factor concerning this topic however there was a lack of information about its importance to the body so a short summary could be included along with some examples of diseases it could cause. &lt;br /&gt;
&lt;br /&gt;
Also, the use of a timeline to present the history is a great idea and I think it could be improved and would look more aesthetically pleasing if it were to be placed into a table. I also think the 1990s, 2000s and 2010s label could be removed to make it look less clustered since they aren’t particularly necessary. &lt;br /&gt;
&lt;br /&gt;
Some information under the heading ‘Technical Progression’ has yet to be filled in but from what is there I’d like to suggest exchanging the bullet points for numbering instead for the information under ‘Pronuclear transfer’ and ‘Polar body transfer’ since they sounded like sequence steps as opposed to separate points. &lt;br /&gt;
&lt;br /&gt;
Finally, I found the layout of the table under the heading ‘Legal status’ to be very well put together. There are however some countries placed under the incorrect continents and I found that the order was easily changed and mixed up. I also noticed that several of the countries were linked to the same sources which made the information very unspecific. Instead of just links I think a few sentences explaining the legislation would be more informative.&lt;br /&gt;
&lt;br /&gt;
===4===&lt;br /&gt;
&lt;br /&gt;
I liked how you guys started the introduction and provides partially a brief overview of what your project is about. But I believe it is not enough to allow the audience an insight to your project page. This is something that needs to be worked on and maybe add some images also. However, the choice of short video used in the introduction is great. This is definitely a benefit for your page as it will reinforce the information you have been trying to get across. Like I mentioned, one thing you could work on is adding images and explaining the content in more depth. There is great amount of reference at the end of the page in the reference list which is fantastic!, however there is no in- text referencing in each section such as introduction or in some of the parts of the “Technical Progression” like “Cytoplasmic transfer” or “Spindle-chromosome transfer”.  Having in-text referencing will allow the audience to know exactly where the information was read from and for the interest of the audience can read that specific paper in detail.&lt;br /&gt;
&lt;br /&gt;
I also noticed that there are no information for “Benefits” and “Legal Status” or there is limited information for such headings like “Ethics”. I’m assuming you didn’t get the chance to upload information there or you haven’t had the time. This is something you need to work on so that the audience has some note of what this page is about. Also you need to change the format of the page for example it is to move the 'Benefits' heading towards the end of the page after the audience gained a good level of understanding of the project. You included some great images but be careful with copyright as I didn’t see it. But also consider some more images, tables, diagrams as well as hand drawn images in some sections, to make it more inviting and not overwhelming with just content. I do appreciate that the section of “Technical Progression” is subdivided into “Human Model”, timeline” and etc. But maybe consider adding in the current research, historic research, limitations and disadvantages to ensure that you can get all the marks possible by addressing all the key concepts. The timeline is a great idea that outlines the significant progresses and in turn helps put major events into perspective, making it more effective for students to study and understand.&lt;br /&gt;
&lt;br /&gt;
Well done on making the “Glossary” at the end. This is exactly what I would have expected to see and I used it while I was reading through your page. Also it is great to see the table in the “Prohibited” section but I would suggest you to write some sentences explaining the legislation rather than just pasting the links.&lt;br /&gt;
&lt;br /&gt;
Overall, this project page has room for improvement by giving certain sections of the page the attention they deserve. Images are imperative in allowing a balance between text and the image itself. Diagrams, tables and animations can sometimes be refreshing, and less overwhelming to see them among paragraphs of content. Try and work on time management, or set a group deadline that everyone has to meet so that all the information can be well up before the due date so your group can have time to edit and add images and play around with the page comfortably. Goodluck!&lt;br /&gt;
&lt;br /&gt;
===5===&lt;br /&gt;
&lt;br /&gt;
It would be nice if the history section could start earlier in time e.g. who came up with the idea of 3 person embryos. It kind of feels as though 3 person embryos popped out of nowhere. This is just a small nuance but the first sentence in “Hereditary mitochondrial Disease” doesn't really make sense.  It sounds incomplete. I think you have too many timelines going on in your page and it makes it a bit confusing. There is one under “History” and another timeline in “technical progression”. I understand they may be timelines for different things, but it’s all too much history. Maybe the “technical progression” timeline could be simplified into a paragraph?&lt;br /&gt;
&lt;br /&gt;
Some sections have too many subsections e.g. “technical progression”, and this makes the section messy and hard to read. It is however good for the table of contents though as it makes it easier to specify what you want to read on the page so my suggestion would be to keep some subheading but cut down a bit. You guys are listing papers to read too often. People want to have the information summarized for them on a wiki page, not have to outsource all the information themselves. It’s too time consuming and if they wanted to read a bunch of articles, they would go on PubMed themselves. However, I do like that some articles have been listed but maybe cut it down to one or two great ones instead of 4-5 etc.&lt;br /&gt;
 &lt;br /&gt;
I really like the table under the subheading “prohibited”, however, it would be nice to have a little summary next to the links about what each countries stance is, because again it’s too time consuming to have to read all those links. I also think some sections need a lot more work e.g. “ethics” and “benefits” and some more words could be added to the glossary. For example, a definition of what the word gamete mean would be good as, whilst we may know what it means, other people who view your page may not.&lt;br /&gt;
&lt;br /&gt;
I really likes the images you used in “technical” progression. They were easy to understand and simplified the text a lot. It would be good however to add a few more images, perhaps to “history”. Some hand-drawn ones would be good. You've got a good amount of references in there, just maybe add a few more. This indicates that you have done significant research and they appear to be correctly cited. The key points of your topic are clearly described and I feel as though your intro., whilst short, really opens up the topic well. Your page relates well to the learning aims of embryology. &lt;br /&gt;
&lt;br /&gt;
To conclude, I think you've got a great framework and some really good information in there. Just makes sure your page doesn't look too busy and is easy to read. A little bit more work needs to be done in some of the sections and a bit more technical touch ups and you should be good!&lt;br /&gt;
&lt;br /&gt;
===6===&lt;br /&gt;
&lt;br /&gt;
Your group’s topic looks very interesting! You have addressed the key points of your topic, and the placement of the video gives the reader a great overview of your project. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''COMMENDATIONS:'''&lt;br /&gt;
&lt;br /&gt;
•	Information has been organised well most of the time. Good use of bullet points and subheadings. &lt;br /&gt;
&lt;br /&gt;
•	The table under “Prohibitions” is a great way of summarising information, and it was easy to read.&lt;br /&gt;
&lt;br /&gt;
•	I like the addition of a glossary, however, more terms could be added here as a lot of jargon has been used in your text. &lt;br /&gt;
&lt;br /&gt;
•	Cytoplasmic transfer images were great as they aided the text well. These images could be re-sized as some of the text is blurry. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''RECOMMENDATIONS:'''&lt;br /&gt;
&lt;br /&gt;
•	Be mindful of spelling and capitalisation, e.g. “Hereditary Mitochondrial Disease” rather than “Hereditory mitochndrial Disease.”&lt;br /&gt;
&lt;br /&gt;
•	In terms of formatting, more spacing between major headings will make reading the page easier and will allow your information to flow.&lt;br /&gt;
&lt;br /&gt;
•	I recommend adopting a set formatting scheme for each section: i.e. make sure that the subheadings are all the same size, that they are in bold/italic (if that is what you intended).&lt;br /&gt;
&lt;br /&gt;
•	Some references and PMIDs are placed throughout the page. These should all be under your References heading at the end of the page.&lt;br /&gt;
&lt;br /&gt;
•	Information is missing under certain headings, e.g. “Mitochondria Linked Infertility.” I’m assuming that information from the two links provided will be summarised for the final submission.&lt;br /&gt;
&lt;br /&gt;
•	Hand drawn image is absent – maybe you could hand draw one of your timelines? (Seeing that both of them currently take the same format/structure). &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Great job so far!&lt;br /&gt;
&lt;br /&gt;
===7===&lt;br /&gt;
&lt;br /&gt;
Thus far, I think this page has a good layout to be a successful page on Three Person Embryos.  The headings and subheadings are relevant and show that you have conducted literature searches to deduce what information needs to be covered. I suggest moving “Benefits” below “Technical Progression” as it is important for the reader to understand the process of three person embryos, before learning its advantages. You could also add information about disadvantages and controversial issues. &lt;br /&gt;
&lt;br /&gt;
On a positive note, I am impressed with the way you have set up headings under “Technical Progression”. The consistency of discussing a model and current research provides a systematic approach to the viewing of your page, making it easy to understand. Delving further in each of these subheadings would provide a greater understanding of the current technologies available, such as including limitations and advantages, and statistics of their success rates. The timeline under “Cytoplasmic Transfer” could probably be incorporated with the timeline under “History” to equalize the amount of content under each heading.  &lt;br /&gt;
&lt;br /&gt;
The content under each heading still needs work in terms of editing and elaboration. There are quite a lot of grammatical and spelling errors such as “Timeline of Mitocondrial Donation” (missing an ‘h’ in mitochondrial), and some sentences aren’t finished. Proofreading would be key to making the information more understandable and effective to the reader. Information seems to be lacking under a few headings especially “Benefits”, “Hereditary Mitochondrial Disease”, “Mitochondria linked Infertility” and “Other approaches”. To make it a bit easier for yourselves, you may want to consider using a table, flow chart for pathogenesis of the disease, and a detailed diagram of the relevant heading. You have provided a table to explain the &amp;quot;Prohibited Section&amp;quot; however a very short description/summary of each source in the table would be very helpful. &lt;br /&gt;
&lt;br /&gt;
I also noticed you have not included many images, videos or tables. These visual aids really help the reader to understand the content in front of them, and also keep their interest in the topic so it imperative to focus on them as much as the content. &lt;br /&gt;
&lt;br /&gt;
The references have all been cited correctly and have shown you have performed adequate research to cover the important information for this topic. As you add more information, more references should be present within the body of your page. &lt;br /&gt;
&lt;br /&gt;
Overall, I think this page has a really good framework for further information to be added. With more editing, content and diagrams, you are sure to produce a wonderful Wiki page.&lt;br /&gt;
&lt;br /&gt;
===8===&lt;br /&gt;
Your project instills a great first impression on a visitor to the page! It is a well designed webpage that doesn’t come across as overwhelming and too wordy encouraging and drawing the reader to explore your page. Your choice of content is relevant and provides a good understanding of the topic so far. The introduction is nice and succinct, explaining easily and clearly what the topic is about with a great video that complements the introduction. Together they give the reader good background information on the topic, and are taught in a way that’s easy for someone with no prior knowledge on the topic or in embryology in general to understand. &lt;br /&gt;
&lt;br /&gt;
Furthermore, the timelines you provided, the ethics section and the table on the legal status of the technique is a good way of showing how far the concept has come and good at placing the technique in the context of how it has been translated into modern society. I really like that you have included animal models in explaining the various techniques, provided the current research available, and included further reading. This is very relevant and interesting for other embryology students and researchers who visit your page! The diagrams you have already chosen are very appropriate and explain the technique clearly to visual learners and are very engaging. &lt;br /&gt;
&lt;br /&gt;
In improving on your page I think the main focus is to elaborate on some key points further and add a few more diagrams and pictures so you can maintain a perfect balance of words and images and the engaging layout you already have begun. For example, maybe for the section “hereditary mitochondrial disease” you can talk about the type of hereditary diseases there are. Also, some of your wording and grammar need further editing so make sure you go through and reread your work. &lt;br /&gt;
&lt;br /&gt;
Other things you should edit include, adding a reference to your introductory paragraph and maybe clarifying that three person embryos are now legal in the UK since your video says “its on the threshold of acceptance”. Also check your copyright on some of the images such as the one that says “Copyright © 2015 BBC. The BBC is not responsible for the content of external sites. Read about our approach to external linking”, I am not sure if this means you are allowed to use it so just clarify this.  &lt;br /&gt;
&lt;br /&gt;
Overall, you have great progress on your page so far, it has a great teaching element to it and shows extensive research and citing into the project!&lt;br /&gt;
&lt;br /&gt;
===9===&lt;br /&gt;
It’s great to begin with a introductory video which defines your topic.  I do suggest finding a reference for the first paragraph for the introduction.  Besides that, references have been cited correctly and shows that you have conducted extensive research, but remember to reference as you add information ( [##] ).  I think you guys did a great job with the heading and subheadings; it shows us that you have done extensive literature research, and have came to a conclusion as to what information was relevant.  Just a grammatical error made in “Timeline of Mitocondrial Donation” which is missing a H in mitochonidral. I suggest proof reading all the text before uploading!  This will make it easier for the audience to understand and also for yourself!  As to the “Benefit” heading, I think it will be a good idea to add information and case studies on disadvantages towards three person embryos.&lt;br /&gt;
&lt;br /&gt;
Nice to see that you guys have included a timeline, this shows the progress made throughout the years.  But I think there is still information that can be added into this area; for example: different possible approaches or more controversial issues that has emerged.  “Technical Progression” is an impressive choice of heading; I found it very interesting to read.  The cytoplasmic transfer images used were great! They were very easy to understand.  The “Timeline” under “Cytoplasmic transfer” could be merged with the history timeline heading above.&lt;br /&gt;
&lt;br /&gt;
Overall, I think more information and content needs to be added under all the headings and subheadings.  To make it easier for the audience to read, I suggest adding detailed images, tables and flowcharts.  It will be more eye-catching for readers and will keep them interested.  I see that you guys have a table under “Prohibited Section” however that just leads to another link, rather than having the link there; I think it would be a great improvement if there is a short summary of all the sources found.&lt;br /&gt;
&lt;br /&gt;
I think your page is organised and formatted very well! With more information/content, detailed diagrams and tables; it will further improve your Wiki Page! Good Luck.&lt;br /&gt;
&lt;br /&gt;
===10===&lt;br /&gt;
Firstly, this is a very impressive wiki and I think you guys are setting the bar very high. The resources you have used and referenced are of really high quality and demonstrate that you have carried out extensive research and identified the information that is most relevant and important. The introductory video and all the images you have included are awesome and really help to solidify the information that you are presenting; they also add more depth to the page and provide further explanation and clarification of the information. The &amp;quot;Technical Progression&amp;quot; section is really great, well structured and provides a lot of explanation about the procedure that I found aided my understanding about major the concepts of the page. &lt;br /&gt;
&lt;br /&gt;
My suggestions to improve your wiki page would be to have a second look at the layout and headings; I found they were difficult to follow and disrupted the flow of the page, for example the heading &amp;quot;Benefits&amp;quot; followed immediately by &amp;quot;Mitochondrial linked information&amp;quot; which was followed again almost immediately by &amp;quot;Hereditary Mitochondrial Disease&amp;quot;. These headings made me stop and think about whether there was some information missing and I was just a little confused about whether the two latter headings came under the first. I really liked the inclusion of the legislation and ethics surrounding the topic (very interesting reading), however I am a bit concerned that they are the biggest portions of the page; I think this would be easily rectified by simple adding further explanations of the current research and journal articles that you have referred to instead of providing only one or two sentences about each. Lastly, it would be really interesting to present information about the controversial opinions/incidents surrounding the topics and also about the disadvantages of the procedures. &lt;br /&gt;
&lt;br /&gt;
Over all, I think you guys have done an awesome job thus far and with a few minor changes the page will be amazing! Good Luck!&lt;br /&gt;
&lt;br /&gt;
===11===&lt;br /&gt;
&lt;br /&gt;
Firstly, I think your page is very well thought out and includes a lot of relevant information. The sub-headings fit in well with the topic and allow for a coherent flow of information, however it would be better if some of the sub-headings were re-arranged. For example, it might be better if the benefits section is placed after technical progression in order to really emphasize the relevance and value of this procedure. Under some sub-headings, it would be good if you could write 3 or 4 sentences summarising that section instead of having the sub-sub heading right underneath, especially for Benefits and Legal Status. This allows for a better flow of information and also makes it look more organised. &lt;br /&gt;
&lt;br /&gt;
In terms of media content, I think the introductory video is great in providing a brief overview of the whole topic. I also think your choice of images for the technical progression section is great in being able to visually summarise the written information. As I could not see an original picture in your page, I think it would be a good idea to include a more visually appealling hand drawn diagram of one of your timelines. You could have the timeline going horizontally with coloured boxes coming off of it to describe the events. This can be easily hand drawn or done in word. &lt;br /&gt;
&lt;br /&gt;
It's clear a lot of research has been done due to the sheer number of articles that have been referenced, especially in reference to the inclusion of several animal and human models. I like your use of timelines however I think the timeline under prohibited section is quite laden with content and can be presented in a more appealing way.      &lt;br /&gt;
&lt;br /&gt;
Overall, I think you guys have done a great job in setting up this page. It has the foundations to becoming a very informative and useful page.&lt;br /&gt;
&lt;br /&gt;
===12===&lt;br /&gt;
The group project page ‘Three Persons Embryos’ covers a lot of aspects of this topic. The page incorporates the example of Alana Saarinen. This ‘personal’ case study makes the topic interesting and makes people want to learn more about it. The video is a good way of introducing the reader to the page, but maybe a summary would be useful for people who cannot/ do not want to access the video. Overall, the headings are in a logical order and the subheadings are useful. However, it might make it easier to follow the page if the subheadings for each of the techniques were unified, e.g. “Procedure” “Animal Models” “Current Research” for each procedure. Also, the heading “Benefits” appears to be rather a description of the indications for the procedure, a renaming of this heading might clarify this. &lt;br /&gt;
&lt;br /&gt;
Many key points relating to the topic have already been mentioned, but expanding further on the majority of headings and subheadings would be useful. Several useful pubmed articles are mentioned where the text is only short, so only their summary is missing. The referencing appears to be correct most of the time, however, there are several instances where one paper was referenced several times individually. Check https://embryology.med.unsw.edu.au/embryology/index.php/Help:Reference_Tutorial#Multiple_Instances_on_Page to learn how to avoid this. &lt;br /&gt;
&lt;br /&gt;
In addition, the three uploaded images need to be double checked for their copyrights, as they do not clearly state an allowance for the reuse of their content. In case, they cannot be reused, the images could be self-drawn. The timelines are interesting and necessary components of the project. They could also be displayed as actual timeline-graphs. This would add to the amount of graphs used and illustrate the content nicely. Overall it might be useful to check for spelling and grammar mistakes before the final deadline.&lt;br /&gt;
 &lt;br /&gt;

&lt;br /&gt;
From first glance of the page, just by looking at the contents table found at the top of the wikipage, I can already see that all the sections have been planned and well thought out with the appropriate subheadings and sub-subheadings which makes the page a lot easier to navigate if I were to be searching for something in particular on the topic ‘Three Person Embryo’&lt;br /&gt;
&lt;br /&gt;
The introduction is short and concise with the appropriate description of what the topic is about, adding the YouTube video in your introduction was a great touch (props to you for asking the maker permission to re-use as it’s under the YouTube Standard License) however I think this section could be improved by maybe addressing the key points that the wiki page will be covering&lt;br /&gt;
&lt;br /&gt;
It’s great to see some history behind the development and progression of ‘Mitochondrial’ Donation throughout the years!! Is there any more history regarding this topic or is 1997 the first date with historical records?? Tabulation of the data may clean up this section, but otherwise great find!&lt;br /&gt;
&lt;br /&gt;
Under the benefits section, no actual benefits seems to have been listed? I think this section has not yet been completed&lt;br /&gt;
&lt;br /&gt;
The pictures and information under the ‘Technical Progression’ subheading is substantial and informative. The images seem to have been referenced and labelled accordingly but not sure if they are reusable as the sites / locations you obtained them from do not mention permission rights for reuse of their material. Some of the referencing done still shows the blue PMID which disrupts the flow of the project page.&lt;br /&gt;
&lt;br /&gt;
It is clear that a lot of research has been done into making this page what it is currently. I would suggest firstly to check that all material used on your page is re-useable as well as fixing up the minor coding of references and also grammar and spelling mistakes throughout the page. Great work!!&lt;br /&gt;
&lt;br /&gt;
===14===&lt;br /&gt;
&lt;br /&gt;
Your project is looking very promising. You have found great resources in you images and video as well as used an ample amount of valid and reliable PUBMED articles to support your findings. You have found a variety of interesting and relevant topics that you have succinctly communicated. I would recommend reviewing  your work for grammatical, punctuation and spelling errors  in your content and your headings.  &lt;br /&gt;
The video and images uploaded are very interesting, please ensue that they are correctly referenced, it would really be a shame if you lost marks on such great parts of your presentation, and more images, to the same quality standard as the Primate model would only improve your project. while the video is a great resource, your should find some journal article evidence to re-affirm its findings, enabling you to not only used the video but also other very reputable sources to validate your statements.  &lt;br /&gt;
&lt;br /&gt;
 The timelines are a great way to succinctly present a lot, of information, easily.  perhaps re-do the Timeline of Mitochondrial Donation as an image, maybe you could incorporate your hand drawn or computer simulated image here. If you wish to reference most of the dates on your timelines - I would suggest either re-referencing the same resource of finding resources to support each date. Endeavour to make all timelines on the wiki page presented in the same manner, ensuring a uniform and cohesive webpage. &lt;br /&gt;
&lt;br /&gt;
Similarly your table under legal status is a great resource, perhaps you could make it a collapsible table, that way it will not take up such a large portion of your page, that could better be used for more content. Perhaps you could review the specific &amp;quot;countries&amp;quot; within the &amp;quot;regions&amp;quot; as some do not match &lt;br /&gt;
&lt;br /&gt;
It would be in your best interest to look into restructuring some of your headings and links especially under Technical progression heading and the Mitochondria linked Infertility heading , and making the effort to present the information in the same manner under each using both animal and human models where applicable. this will make your web page easier to read and understand :) formatting is super important, spacing between subheadings as well as pictures  break up the information and make it easier to read. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Certain areas within your report and good but could use a little more content such as the intoduction as well as  Hereditory mitochondrial Disease in order to provided a well rounded base level of understanding for all users of this site. Many Pubmed links and references are scattered throughout the web page, these should be correctly coded and placed in the reference list, perhaps instead of having the articles there you could summaries the findings for the readers, it would be easier than having them outsource the information. Be careful of over referencing your pubmed articles and more key word that are being repeated should be incorporated into your glossary.  &lt;br /&gt;
&lt;br /&gt;
On the whole good work so far, I look forward to seeing the final result.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===15===&lt;br /&gt;
&lt;br /&gt;
This Group Project has a lot of potential. Information is presented in an engaging way through an introductory video documenting a case, timeline providing retrospective insight as well as diagrams detailing the complex processes in a concise manner. I also found some subsections interesting and relevant, including the discussion on ethics, Current research areas, as well as the glossary which provides a quick reference.&lt;br /&gt;
&lt;br /&gt;
Although I understand you intend to elaborate more on certain areas including current research, the project does seem a little thin in regards to text. There are many papers that are linked with no explanation. For example, with regards to the table under prohibitions, I am confused as to what exactly those countries prohibit (all genetic modification? mitochondrial techniques only?) and also whether there is any more nuance to the discussion (do they ban different things?). Of course, one could click through the links under each country, but i think some text before the table itself would only add to your project and bring more context to the table itself. Diagrams themselves can also be referred to in the text (as you would find in a textbook), to add context and create a more cohesive wikipedia page (e.g. for Pronuclear transfer). In terms of the information provided, a little deeper exploration or discussion about certain issues including the reasoning behind ethics arguments may be relevant. If the articles listed under the headings are anything to go by, it seems you intend to do this. &lt;br /&gt;
&lt;br /&gt;
Finally, some proofreading will be very beneficial in polishing up the wikipedia page. There are some sentences like &amp;quot;And it effectiveness in doing so. And the processes that occur in the oocyte when this method is used&amp;quot; under Human Embryo Model, which may well do with some editing. I would like to add that the referencing has been fantastic and consistent. Good Luck!&lt;br /&gt;
&lt;br /&gt;
===16===&lt;br /&gt;
&lt;br /&gt;
The entire group project is short in comparison to other reports. Adding a video about a teenage girl who has three biological parents is an excellent tool to engage the readers. Regarding the history, the timelines used help structure the changes over time and allow easier reading, although it is reality short for the entire history, possibly add one or two more paragraphs covering all aspects of the history of three-person embryo. Benefits section wasn’t completed equally as some sections such as the mitochondria linked infertility and Hereditary mitochondrial disease are fairly small in comparison to the technical progression.&lt;br /&gt;
&lt;br /&gt;
Diagrams, more timelines and human models were used and discusses which is a valuable asset to the project. As well as large tables discussing where this procedure is prohibited. Overall this group project reaches out to different aspects of three person embryos although it still has a long way to go, certain sections need to be updated with information, and some other sections need to be clarified more with the addition of vital information.&lt;br /&gt;
&lt;br /&gt;
Adding further reading clearly shows that the group are interested in the topic they have chosen and have taken the time to add additional links for people who are interested in reading up on three person embryos. Also the glossary is way too small, it needs to include a lot more definitions, which is due to the lack of information in the overall set out of the project. The citations and references are filled out correctly and help with the clarity of the report.&lt;br /&gt;
&lt;br /&gt;
===17===&lt;br /&gt;
The topic of three person’s embryo was outlined and described well, with good choice of headings, separating the different key points and areas that you’ve discussed on your page. It’s evident you’ve done extensive research on your topic, and especially going through your reference list, all your research data were extremely recent, which is excellent!&lt;br /&gt;
&lt;br /&gt;
&amp;lt;b&amp;gt;Pros&amp;lt;/b&amp;gt;&lt;br /&gt;
*I loved that you put an introductory video in the beginning, which is a personal account rather than a scientific stimulation video, giving it a more personal touch on the page, and highlighting the importance of this breakthrough in 3 person’s embryos. &lt;br /&gt;
*Because your topic isn’t a disease but a medical breakthrough, your own chosen headings were fantastic and on point, giving a well-rounded and detailed wiki page&lt;br /&gt;
*The format of the page is also really good. Its good to use more subheadings than main headings, and you’ve formatted the page really well&lt;br /&gt;
*You’ve used very current research, making your page much more credible and updated with the newest information&lt;br /&gt;
*The “further reading” section was really good, it extended beyond the normal “teaching” topics, giving the reader a better insight of the topic, if they choose to.&lt;br /&gt;
&amp;lt;b&amp;gt;Cons&amp;lt;/b&amp;gt;&lt;br /&gt;
*The introduction looked a bit short. A more detailed explanation will make the reader understand a lot more on how it works and how the page looks, without the reader having to watch the video if they choose to just skim the page.&lt;br /&gt;
*Your heading and subheading of “History” and “Timeline” could’ve been merged into one, as that was  your only subheading of that heading,it would’ve looked more readable that way&lt;br /&gt;
*Timeline information could be extended more, in terms of date (if found) and details on what occurred on that date&lt;br /&gt;
*The heading of “Benefits” also needs to be extended VERY much more, two subheadings an 3 sentences under one, with a link under the other, does not explain any benefits at all&lt;br /&gt;
*Pictures in “Technical Progression” could be skewed to the right, so the words all flow, with the HELP of the diagram, instead of the focus being on the photos&lt;br /&gt;
*Current research also needs to be expanded more. PMID wouldn’t be needed either if you had expanded the current research, and referenced it in your reference list; section looks a bit messy with bullet points starting with hyperlink&lt;br /&gt;
*“Technical Progression” needs to be greatly edited and to have information added&lt;br /&gt;
*“Ethics” also needs to be expanded, and again, don’t lead with PMID&lt;br /&gt;
*“Glossary” is not really needed if you explain those terms in each words occurrence instead of at the end, but this is a minute point&lt;/div&gt;</summary>

&lt;br /&gt;
Heat stress has previously seen a decrease in fertility in dairy cows, whilst similarly, pregnancy rates in women are recorded to be lowest during the summer season, paving way for the postulation that fertilization may be disrupted due to elevated temperatures. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
3 different experiments were performed to determine the underlying mechanism causing the disruption to fertilization due to increase in temperature. Oocytes and Spermatozoa were exposed to physiological temperatures that mirrored those of mammalian organisms. Oocytes were fertilized at 38.5-41ºC with either no-pre-incubated sperm or 38.5 / 41ºC incubated sperm, to investigate the effected on sperm plasma membrane, viability, and penetration, polyspermy, subsequent development of zygote, and embryonic competence. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
The results showed that at elevated temperatures, percentage of motile sperm were reduced, along with altered transcription due to oxidative stress, resulting in an increase in polyspermy. In addition, the zona pellucida of zygotes was sensitive to pronase digestion during heat stress, and exhibited decreased transcription of gene UCHL1, which played the role of preventing polyspermy. Rates of cell cleave and blastocysts formation were also seen to have reduced. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
Because of the results shown, this study reports that the increase in polyspermy is the most likely cause of the reduced blastocyst formation due to the reduced capability of zygotes at elevated temperatures to develop to the next stage. (Sakatani et all, 2014)&lt;br /&gt;

&lt;br /&gt;
Cyclophosphamide is an alkylating agent most commonly used to treat cancers with other chemotherapy agents. It’s used to quickly control cancerous diseases but is highly toxic. Sperm banking in those prior to cancer treatment have seen to have more effective Intracytoplasmic Sperm Injection in In Vitro Fertilization compared to those performing IVF/ICSI after their first dose of chemotherapy. This study tests whether there is correlation between the agent, Cyclophosphamide, and the reduced preimplantation embryo development, birth rate, and genetic integrity of embryos after embryo transfer. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Untreated sperm of adult male B6D2 mice were first collected. They were then administered cyclophosphamide after seven days, and were sacrificed to obtain the treated sperm. Oocytes were collected after controlled ovarian stimulation. Half the oocytes from each female were exposed with Cyclophosphamide exposed sperm and untreated sperm from the same male mice. Embryos were monitored in vitro for 2 days and were then collected for exome sequencing. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Results showed that the average percentage of oocyte survival was 94.8%, whereas for embryos treated with Cyclophosphamide, percentage of survival was significantly lowered to 49%. Birth rates after embryo transfer showed no difference between the two groups but Cyclophosphamide-treated group had lower litter size (0.8 vs 3.8) and pups per embryo transferred (2.7% vs. 14%). (Johnson et all, 2015)&lt;br /&gt;
This study argues that Cyclophosphamide exposed sperm decreased development in embryo, resulting in lowered numbers of offspring and lower number of offspring survival. Further investigation is needed in order to know the reason and mechanism behind Cyclophosphamide’s influence on male sperm and fertilization. (Johnson et all, 2015)&lt;br /&gt;

&lt;br /&gt;
MR imaging has extended its use to evaluating and diagnosing disorders related to female infertility, including ovulatory, fallopian tube, and uterine disorders, and also pelvic enometiosis. It is used in a variety of clinical settings by providing a clear vizualization of the pelvic region and is now useful in conjunction with other diagnostic techniques like laparoscopy, hysteroscopy, and hysterosalpinogography.&lt;br /&gt;
&lt;br /&gt;

In a group of 77 women evaluated, Laparoscopy confirmed 84% evidence of tubal disease and hysteroscopy confirmed 69% radiographic evidence of intrauterine abnormalities. IN contrast HS gave a false-positive rate of 16% and 31% respectively. Data suggests that laparoscopy is best detecting previously unsuspected tubal disease, and hysteroscopy with information of managing abnormalities. But for optimum evaluation, a combined approach of all three procedures is best.&lt;br /&gt;

Earlier assessment is best in women who have history of oligomenorrhea/amenorrhea, with key objective of assessment and diagnosis to rule out azoospermia, anovulation, or tubal obstruction.&lt;br /&gt;
In order to do so an assesment of ovulatory function, uterine cavity, and tubal patency by HSG/laparoscopyis needed.&lt;br /&gt;
Assessments like post coital tests, endometrial biopsies, and basal bdy temperature records are no longer a routine investigation.&lt;br /&gt;

*You’ve used very current research, making your page much more credible and updated with the newest information&lt;br /&gt;
*The “further reading” section was really good, it extended beyond the normal “teaching” topics, giving the reader a better insight of the topic, if they choose to.&lt;br /&gt;
&amp;lt;b&amp;gt;Cons&amp;lt;/b&amp;gt;&lt;br /&gt;
*The introduction looked a bit short. A more detailed explanation will make the reader understand a lot more on how it works and how the page looks, without the reader having to watch the video if they choose to just skim the page.&lt;br /&gt;
*Your heading and subheading of “History” and “Timeline” could’ve been merged into one, as that was  your only subheading of that heading,it would’ve looked more readable that way&lt;br /&gt;
*Timeline information could be extended more, in terms of date (if found) and details on what occurred on that date&lt;br /&gt;
*The heading of “Benefits” also needs to be extended VERY much more, two subheadings an 3 sentences under one, with a link under the other, does not explain any benefits at all&lt;br /&gt;
*Pictures in “Technical Progression” could be skewed to the right, so the words all flow, with the HELP of the diagram, instead of the focus being on the photos&lt;br /&gt;
*Current research also needs to be expanded more. PMID wouldn’t be needed either if you had expanded the current research, and referenced it in your reference list; section looks a bit messy with bullet points starting with hyperlink&lt;br /&gt;
*“Technical Progression” needs to be greatly edited and to have information added&lt;br /&gt;
*“Ethics” also needs to be expanded, and again, don’t lead with PMID&lt;br /&gt;
*“Glossary” is not really needed if you explain those terms in each words occurrence instead of at the end, but this is a minute point&lt;br /&gt;
&lt;br /&gt;
===Group 2===&lt;br /&gt;
The topic of OHSS was outlined very well, with very good choice of headings, separating the different key points and areas that you’ve discussed on your page. It’s evident you’ve done extensive research on your topic, and all your information is very concise and very readable. You’ve also extended your topic beyond the general symptoms, diagnosis, causes etc like “animal models” “effect on the newborn”, it is very extensive!&lt;br /&gt;
&amp;lt;b&amp;gt;Pros&amp;lt;/b&amp;gt;&lt;br /&gt;
*Extensive research evident, a lot of information is provided&lt;br /&gt;
*Introduction is short and concise, but also extremely informative, highlighting the aim of the page as well!&lt;br /&gt;
*Statistics of the disease is also given, numerical data is always good&lt;br /&gt;
*Good use of a table in “Symptoms”, making it very readable and engaging&lt;br /&gt;
*The presence and position of the drawing in “Pathophysiology” is prenominal, you’ve gone out of your way to draw a diagram to illustrate the topic&lt;br /&gt;
*Good use of bullet points in “Treatment”, very concise and readable and there isn’t a jumble of words&lt;br /&gt;
&amp;lt;b&amp;gt;Cons&amp;lt;/b&amp;gt;&lt;br /&gt;
*A photo or video in your introduction could be used to illustrate what the topic is better&lt;br /&gt;
*There’s a lot of technical jargon already in your introduction, words like neoangiogenesis and iatrogenic. Readers who come to your page may not necessarily understand those words. These words can be defined in your glossary, but readers read in logical flow, they won’t scroll all the way to the bottom of your page because they didn’t understand the word to find the meaning then come back to the introduction to continue. These words don’t have to be replaced, but an explanation might ease your cause&lt;br /&gt;
*A graph or table or pie chart representing epidemiology will make the heading more informative&lt;br /&gt;
*Photos showing symptoms will substantially help, especially when they’re separated into mild, moderate, and sever.&lt;br /&gt;
*Diagnosis needs to be expanded more. The bold type words should be made into subheadings so you can expand on each more, defining how and why they are performed&lt;br /&gt;
*Headings of “effect on the newborn” and “animal models” need to be completed&lt;br /&gt;
*You have a lot of information on your page but only a few are referenced, a lot more in text referencing and references are needed for the amount of information you have&lt;br /&gt;
&lt;br /&gt;
===Group 4===&lt;br /&gt;
*The structure of your page is extremely excellent! It flows very well, all headings and subheadings were chosen really well, the use of tables and diagrams are incredible!&lt;br /&gt;
*The heading of “Background information” is VERY extensive, and also concise! The diagram placement is also excellent, and their use is also extremely excellent&lt;br /&gt;
*The use of the video to explain the cause of infertility is absolutely amazing, it makes your page look good, keeps your explanation short, concise, and readable, and it also engages the audience&lt;br /&gt;
*Each subheading under “Causes” is also very well outlined and explained, there is a lot of information there, and it is sure whatever information the reader may need would be found on your page as it has covered and explained a lot&lt;br /&gt;
Overall, all I have for your group are good comments, as I couldn’t think of anything else that you will might need to add or change on it at all! Your information extends beyond what is expected, but also extensive, concise, and, most importantly, extremely readable and engaging! GOOD WORK!&lt;br /&gt;
&lt;br /&gt;
===Group 5===&lt;br /&gt;
Your information extends beyond what is expected, but also extensive and readable and engaging. The page is formatted really well.&lt;br /&gt;
&amp;lt;b&amp;gt;Pros&amp;lt;/b&amp;gt;&lt;br /&gt;
*The structure of your page is really good. It flows well, all headings and subheadings were chosen really well, the use of diagrams keeps it engaging&lt;br /&gt;
*Each subheading is chosen and highlighted well&lt;br /&gt;
*A very extensive reference list, making it evident that you have researched your topic thoroughly!&lt;br /&gt;
&amp;lt;b&amp;gt;Cons&amp;lt;/b&amp;gt;&lt;br /&gt;
*Use of diagrams and photos in the introductory parts of your page will make your page much more engaging&lt;br /&gt;
*You may have extensive information but its not too concise. At a glance of your page, all you see are huge jumbles of words, and if you read the information, it needs to be summarized a lot more&lt;br /&gt;
*Photos in Surgery and Fertility Drugs can make it more interesting and it can help you explain them more on what it looks like and whats involved using a single image&lt;br /&gt;
*The use of the video explanation is also very good, but keep in mind that this page isn’t really aimed for people with minimal knowledge on cancer cells, but those trying to extend their knowledge, so they would already know about cancer cells. (Less is more)&lt;br /&gt;
*Use a table in Chemotherapy Drugs can make long lists look much better&lt;br /&gt;
*Reserve subheadings for your bold keywords underneath “Fertility preservation in women” instead of just bold type, it will look much more organized&lt;br /&gt;

&lt;br /&gt;
Heat stress has previously seen a decrease in fertility in dairy cows, whilst similarly, pregnancy rates in women are recorded to be lowest during the summer season, paving way for the postulation that fertilization may be disrupted due to elevated temperatures. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
3 different experiments were performed to determine the underlying mechanism causing the disruption to fertilization due to increase in temperature. Oocytes and Spermatozoa were exposed to physiological temperatures that mirrored those of mammalian organisms. Oocytes were fertilized at 38.5-41ºC with either no-pre-incubated sperm or 38.5 / 41ºC incubated sperm, to investigate the effected on sperm plasma membrane, viability, and penetration, polyspermy, subsequent development of zygote, and embryonic competence. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
The results showed that at elevated temperatures, percentage of motile sperm were reduced, along with altered transcription due to oxidative stress, resulting in an increase in polyspermy. In addition, the zona pellucida of zygotes was sensitive to pronase digestion during heat stress, and exhibited decreased transcription of gene UCHL1, which played the role of preventing polyspermy. Rates of cell cleave and blastocysts formation were also seen to have reduced. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
Because of the results shown, this study reports that the increase in polyspermy is the most likely cause of the reduced blastocyst formation due to the reduced capability of zygotes at elevated temperatures to develop to the next stage. (Sakatani et all, 2014)&lt;br /&gt;

&lt;br /&gt;
Cyclophosphamide is an alkylating agent most commonly used to treat cancers with other chemotherapy agents. It’s used to quickly control cancerous diseases but is highly toxic. Sperm banking in those prior to cancer treatment have seen to have more effective Intracytoplasmic Sperm Injection in In Vitro Fertilization compared to those performing IVF/ICSI after their first dose of chemotherapy. This study tests whether there is correlation between the agent, Cyclophosphamide, and the reduced preimplantation embryo development, birth rate, and genetic integrity of embryos after embryo transfer. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Untreated sperm of adult male B6D2 mice were first collected. They were then administered cyclophosphamide after seven days, and were sacrificed to obtain the treated sperm. Oocytes were collected after controlled ovarian stimulation. Half the oocytes from each female were exposed with Cyclophosphamide exposed sperm and untreated sperm from the same male mice. Embryos were monitored in vitro for 2 days and were then collected for exome sequencing. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Results showed that the average percentage of oocyte survival was 94.8%, whereas for embryos treated with Cyclophosphamide, percentage of survival was significantly lowered to 49%. Birth rates after embryo transfer showed no difference between the two groups but Cyclophosphamide-treated group had lower litter size (0.8 vs 3.8) and pups per embryo transferred (2.7% vs. 14%). (Johnson et all, 2015)&lt;br /&gt;
This study argues that Cyclophosphamide exposed sperm decreased development in embryo, resulting in lowered numbers of offspring and lower number of offspring survival. Further investigation is needed in order to know the reason and mechanism behind Cyclophosphamide’s influence on male sperm and fertilization. (Johnson et all, 2015)&lt;br /&gt;

===Female Infertility : Diagnosis===&lt;br /&gt;
====MR imaging of disorders associated with female infertility: use in diagnosis, treatment, and management.&amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;14615553&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;====&lt;br /&gt;
&lt;br /&gt;
MR imaging has extended its use to evaluating and diagnosing disorders related to female infertility, including ovulatory, fallopian tube, and uterine disorders, and also pelvic enometiosis. It is used in a variety of clinical settings by providing a clear vizualization of the pelvic region and is now useful in conjunction with other diagnostic techniques like laparoscopy, hysteroscopy, and hysterosalpinogography.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;i&amp;gt; PMID 14615553 &amp;lt;/i&amp;gt;&lt;br /&gt;

====Comparison of diagnostic accuracy of laparoscopy, hysteroscopy, and hysterosalpingography in evaluation of female infertility. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;6232154 &amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;====&lt;br /&gt;
In a group of 77 women evaluated, Laparoscopy confirmed 84% evidence of tubal disease and hysteroscopy confirmed 69% radiographic evidence of intrauterine abnormalities. IN contrast HS gave a false-positive rate of 16% and 31% respectively. Data suggests that laparoscopy is best detecting previously unsuspected tubal disease, and hysteroscopy with information of managing abnormalities. But for optimum evaluation, a combined approach of all three procedures is best.&lt;br /&gt;

Earlier assessment is best in women who have history of oligomenorrhea/amenorrhea, with key objective of assessment and diagnosis to rule out azoospermia, anovulation, or tubal obstruction.&lt;br /&gt;
In order to do so an assesment of ovulatory function, uterine cavity, and tubal patency by HSG/laparoscopyis needed.&lt;br /&gt;
Assessments like post coital tests, endometrial biopsies, and basal bdy temperature records are no longer a routine investigation.&lt;br /&gt;

The topic of three person’s embryo was outlined and described well, with good choice of headings, separating the different key points and areas that you’ve discussed on your page. It’s evident you’ve done extensive research on your topic, and especially going through your reference list, all your research data were extremely recent, which is excellent!&lt;br /&gt;
&lt;br /&gt;
&amp;lt;b&amp;gt;Pros&amp;lt;/b&amp;gt;&lt;br /&gt;
*I loved that you put an introductory video in the beginning, which is a personal account rather than a scientific stimulation video, giving it a more personal touch on the page, and highlighting the importance of this breakthrough in 3 person’s embryos. &lt;br /&gt;
*Because your topic isn’t a disease but a medical breakthrough, your own chosen headings were fantastic and on point, giving a well-rounded and detailed wiki page&lt;br /&gt;

&amp;lt;b&amp;gt;Cons&amp;lt;/b&amp;gt;&lt;br /&gt;
*The introduction looked a bit short. A more detailed explanation will make the reader understand a lot more on how it works and how the page looks, without the reader having to watch the video if they choose to just skim the page.&lt;br /&gt;
*Your heading and subheading of “History” and “Timeline” could’ve been merged into one, as that was  your only subheading of that heading,it would’ve looked more readable that way&lt;br /&gt;
*Timeline information could be extended more, in terms of date (if found) and details on what occurred on that date&lt;br /&gt;
*The heading of “Benefits” also needs to be extended VERY much more, two subheadings an 3 sentences under one, with a link under the other, does not explain any benefits at all&lt;br /&gt;
*Pictures in “Technical Progression” could be skewed to the right, so the words all flow, with the HELP of the diagram, instead of the focus being on the photos&lt;br /&gt;
*Current research also needs to be expanded more. PMID wouldn’t be needed either if you had expanded the current research, and referenced it in your reference list; section looks a bit messy with bullet points starting with hyperlink&lt;br /&gt;
*“Technical Progression” needs to be greatly edited and to have information added&lt;br /&gt;

*A photo or video in your introduction could be used to illustrate what the topic is better&lt;br /&gt;
*There’s a lot of technical jargon already in your introduction, words like neoangiogenesis and iatrogenic. Readers who come to your page may not necessarily understand those words. These words can be defined in your glossary, but readers read in logical flow, they won’t scroll all the way to the bottom of your page because they didn’t understand the word to find the meaning then come back to the introduction to continue. These words don’t have to be replaced, but an explanation might ease your cause&lt;br /&gt;
*A graph or table or pie chart representing epidemiology will make the heading more informative&lt;br /&gt;
*Photos showing symptoms will substantially help, especially when they’re separated into mild, moderate, and sever.&lt;br /&gt;
*Diagnosis needs to be expanded more. The bold type words should be made into subheadings so you can expand on each more, defining how and why they are performed&lt;br /&gt;
*Headings of “effect on the newborn” and “animal models” need to be completed&lt;br /&gt;
*You have a lot of information on your page but only a few are referenced, a lot more in text referencing and references are needed for the amount of information you have&lt;br /&gt;
&lt;br /&gt;
====Group 4====&lt;br /&gt;
*The structure of your page is extremely excellent! It flows very well, all headings and subheadings were chosen really well, the use of tables and diagrams are incredible!&lt;br /&gt;
*The heading of “Background information” is VERY extensive, and also concise! The diagram placement is also excellent, and their use is also extremely excellent&lt;br /&gt;
*The use of the video to explain the cause of infertility is absolutely amazing, it makes your page look good, keeps your explanation short, concise, and readable, and it also engages the audience&lt;br /&gt;
*Each subheading under “Causes” is also very well outlined and explained, there is a lot of information there, and it is sure whatever information the reader may need would be found on your page as it has covered and explained a lot&lt;br /&gt;
Overall, all I have for your group are good comments, as I couldn’t think of anything else that you will might need to add or change on it at all! Your information extends beyond what is expected, but also extensive, concise, and, most importantly, extremely readable and engaging! GOOD WORK!&lt;br /&gt;
&lt;br /&gt;
====Group 5====&lt;br /&gt;
Your information extends beyond what is expected, but also extensive and readable and engaging. The page is formatted really well.&lt;br /&gt;
&amp;lt;b&amp;gt;Pros&amp;lt;/b&amp;gt;&lt;br /&gt;
*The structure of your page is really good. It flows well, all headings and subheadings were chosen really well, the use of diagrams keeps it engaging&lt;br /&gt;
*Each subheading is chosen and highlighted well&lt;br /&gt;
*A very extensive reference list, making it evident that you have researched your topic thoroughly!&lt;br /&gt;
&amp;lt;b&amp;gt;Cons&amp;lt;/b&amp;gt;&lt;br /&gt;
*Use of diagrams and photos in the introductory parts of your page will make your page much more engaging&lt;br /&gt;
*You may have extensive information but its not too concise. At a glance of your page, all you see are huge jumbles of words, and if you read the information, it needs to be summarized a lot more&lt;br /&gt;
*Photos in Surgery and Fertility Drugs can make it more interesting and it can help you explain them more on what it looks like and whats involved using a single image&lt;br /&gt;
*The use of the video explanation is also very good, but keep in mind that this page isn’t really aimed for people with minimal knowledge on cancer cells, but those trying to extend their knowledge, so they would already know about cancer cells. (Less is more)&lt;br /&gt;
*Use a table in Chemotherapy Drugs can make long lists look much better&lt;br /&gt;
*Reserve subheadings for your bold keywords underneath “Fertility preservation in women” instead of just bold type, it will look much more organized&lt;br /&gt;

&lt;br /&gt;
Heat stress has previously seen a decrease in fertility in dairy cows, whilst similarly, pregnancy rates in women are recorded to be lowest during the summer season, paving way for the postulation that fertilization may be disrupted due to elevated temperatures. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
3 different experiments were performed to determine the underlying mechanism causing the disruption to fertilization due to increase in temperature. Oocytes and Spermatozoa were exposed to physiological temperatures that mirrored those of mammalian organisms. Oocytes were fertilized at 38.5-41ºC with either no-pre-incubated sperm or 38.5 / 41ºC incubated sperm, to investigate the effected on sperm plasma membrane, viability, and penetration, polyspermy, subsequent development of zygote, and embryonic competence. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
The results showed that at elevated temperatures, percentage of motile sperm were reduced, along with altered transcription due to oxidative stress, resulting in an increase in polyspermy. In addition, the zona pellucida of zygotes was sensitive to pronase digestion during heat stress, and exhibited decreased transcription of gene UCHL1, which played the role of preventing polyspermy. Rates of cell cleave and blastocysts formation were also seen to have reduced. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
Because of the results shown, this study reports that the increase in polyspermy is the most likely cause of the reduced blastocyst formation due to the reduced capability of zygotes at elevated temperatures to develop to the next stage. (Sakatani et all, 2014)&lt;br /&gt;

&lt;br /&gt;
Cyclophosphamide is an alkylating agent most commonly used to treat cancers with other chemotherapy agents. It’s used to quickly control cancerous diseases but is highly toxic. Sperm banking in those prior to cancer treatment have seen to have more effective Intracytoplasmic Sperm Injection in In Vitro Fertilization compared to those performing IVF/ICSI after their first dose of chemotherapy. This study tests whether there is correlation between the agent, Cyclophosphamide, and the reduced preimplantation embryo development, birth rate, and genetic integrity of embryos after embryo transfer. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Untreated sperm of adult male B6D2 mice were first collected. They were then administered cyclophosphamide after seven days, and were sacrificed to obtain the treated sperm. Oocytes were collected after controlled ovarian stimulation. Half the oocytes from each female were exposed with Cyclophosphamide exposed sperm and untreated sperm from the same male mice. Embryos were monitored in vitro for 2 days and were then collected for exome sequencing. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Results showed that the average percentage of oocyte survival was 94.8%, whereas for embryos treated with Cyclophosphamide, percentage of survival was significantly lowered to 49%. Birth rates after embryo transfer showed no difference between the two groups but Cyclophosphamide-treated group had lower litter size (0.8 vs 3.8) and pups per embryo transferred (2.7% vs. 14%). (Johnson et all, 2015)&lt;br /&gt;
This study argues that Cyclophosphamide exposed sperm decreased development in embryo, resulting in lowered numbers of offspring and lower number of offspring survival. Further investigation is needed in order to know the reason and mechanism behind Cyclophosphamide’s influence on male sperm and fertilization. (Johnson et all, 2015)&lt;br /&gt;

===Female Infertility : Diagnosis===&lt;br /&gt;
====MR imaging of disorders associated with female infertility: use in diagnosis, treatment, and management.&amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;14615553&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;====&lt;br /&gt;
&lt;br /&gt;
MR imaging has extended its use to evaluating and diagnosing disorders related to female infertility, including ovulatory, fallopian tube, and uterine disorders, and also pelvic enometiosis. It is used in a variety of clinical settings by providing a clear vizualization of the pelvic region and is now useful in conjunction with other diagnostic techniques like laparoscopy, hysteroscopy, and hysterosalpinogography.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;i&amp;gt; PMID 14615553 &amp;lt;/i&amp;gt;&lt;br /&gt;
&lt;br /&gt;
====Comparison of diagnostic accuracy of laparoscopy, hysteroscopy, and hysterosalpingography in evaluation of female infertility. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;6232154 &amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;====&lt;br /&gt;
In a group of 77 women evaluated, Laparoscopy confirmed 84% evidence of tubal disease and hysteroscopy confirmed 69% radiographic evidence of intrauterine abnormalities. IN contrast HS gave a false-positive rate of 16% and 31% respectively. Data suggests that laparoscopy is best detecting previously unsuspected tubal disease, and hysteroscopy with information of managing abnormalities. But for optimum evaluation, a combined approach of all three procedures is best.&lt;br /&gt;

Earlier assessment is best in women who have history of oligomenorrhea/amenorrhea, with key objective of assessment and diagnosis to rule out azoospermia, anovulation, or tubal obstruction.&lt;br /&gt;
In order to do so an assesment of ovulatory function, uterine cavity, and tubal patency by HSG/laparoscopyis needed.&lt;br /&gt;
Assessments like post coital tests, endometrial biopsies, and basal bdy temperature records are no longer a routine investigation.&lt;br /&gt;

====Group 1====&lt;br /&gt;
The topic of three person’s embryo was outlined and described well, with good choice of headings, separating the different key points and areas that you’ve discussed on your page. It’s evident you’ve done extensive research on your topic, and especially going through your reference list, all your research data were extremely recent, which is excellent!&lt;br /&gt;
Pros:&lt;br /&gt;
-	I loved that you put an introductory video in the beginning, which is a personal account rather than a scientific stimulation video, giving it a more personal touch on the page, and highlighting the importance of this breakthrough in 3 person’s embryos. &lt;br /&gt;
-	Because your topic isn’t a disease but a medical breakthrough, your own chosen headings were fantastic and on point, giving a well-rounded and detailed wiki page&lt;br /&gt;
-	The format of the page is also really good. Its good to use more subheadings than main headings, and you’ve formatted the page really well&lt;br /&gt;
-	You’ve used very current research, making your page much more credible and updated with the newest information&lt;br /&gt;
-	The “further reading” section was really good, it extended beyond the normal “teaching” topics, giving the reader a better insight of the topic, if they choose to.&lt;br /&gt;
Cons:&lt;br /&gt;
-	The introduction looked a bit short. A more detailed explanation will make the reader understand a lot more on how it works and how the page looks, without the reader having to watch the video if they choose to just skim the page.&lt;br /&gt;
-	Your heading and subheading of “History” and “Timeline” could’ve been merged into one, as that was  your only subheading of that heading,it would’ve looked more readable that way&lt;br /&gt;
-	Timeline information could be extended more, in terms of date (if found) and details on what occurred on that date&lt;br /&gt;
-	The heading of “Benefits” also needs to be extended VERY much more, two subheadings an 3 sentences under one, with a link under the other, does not explain any benefits at all&lt;br /&gt;
-	Pictures in “Technical Progression” could be skewed to the right, so the words all flow, with the HELP of the diagram, instead of the focus being on the photos&lt;br /&gt;
-	Current research also needs to be expanded more. PMID wouldn’t be needed either if you had expanded the current research, and referenced it in your reference list; section looks a bit messy with bullet points starting with hyperlink&lt;br /&gt;
-	“Technical Progression” needs to be greatly edited and to have information added&lt;br /&gt;
-	“Ethics” also needs to be expanded, and again, don’t lead with PMID&lt;br /&gt;
-	“Glossary” is not really needed if you explain those terms in each words occurrence instead of at the end, but this is a minute point&lt;br /&gt;
&lt;br /&gt;
====Group 2====&lt;br /&gt;
The topic of OHSS was outlined very well, with very good choice of headings, separating the different key points and areas that you’ve discussed on your page. It’s evident you’ve done extensive research on your topic, and all your information is very concise and very readable. You’ve also extended your topic beyond the general symptoms, diagnosis, causes etc like “animal models” “effect on the newborn”, it is very extensive!&lt;br /&gt;
Pros:&lt;br /&gt;
-	Extensive research evident, a lot of information is provided&lt;br /&gt;
-	Introduction is short and concise, but also extremely informative, highlighting the aim of the page as well!&lt;br /&gt;
-	Statistics of the disease is also given, numerical data is always good&lt;br /&gt;
-	Good use of a table in “Symptoms”, making it very readable and engaging&lt;br /&gt;
-	The presence and position of the drawing in “Pathophysiology” is prenominal, you’ve gone out of your way to draw a diagram to illustrate the topic&lt;br /&gt;
-	Good use of bullet points in “Treatment”, very concise and readable and there isn’t a jumble of words&lt;br /&gt;
Cons&lt;br /&gt;
-	A photo or video in your introduction could be used to illustrate what the topic is better&lt;br /&gt;
-	There’s a lot of technical jargon already in your introduction, words like neoangiogenesis and iatrogenic. Readers who come to your page may not necessarily understand those words. These words can be defined in your glossary, but readers read in logical flow, they won’t scroll all the way to the bottom of your page because they didn’t understand the word to find the meaning then come back to the introduction to continue. These words don’t have to be replaced, but an explanation might ease your cause&lt;br /&gt;
-	A graph or table or pie chart representing epidemiology will make the heading more informative&lt;br /&gt;
-	Photos showing symptoms will substantially help, especially when they’re separated into mild, moderate, and sever.&lt;br /&gt;
-	Diagnosis needs to be expanded more. The bold type words should be made into subheadings so you can expand on each more, defining how and why they are performed&lt;br /&gt;
-	Headings of “effect on the newborn” and “animal models” need to be completed&lt;br /&gt;
-	You have a lot of information on your page but only a few are referenced, a lot more in text referencing and references are needed for the amount of information you have&lt;br /&gt;
&lt;br /&gt;
====Group 4====&lt;br /&gt;
-	The structure of your page is extremely excellent! It flows very well, all headings and subheadings were chosen really well, the use of tables and diagrams are incredible!&lt;br /&gt;
-	The heading of “Background information” is VERY extensive, and also concise! The diagram placement is also excellent, and their use is also extremely excellent&lt;br /&gt;
-	The use of the video to explain the cause of infertility is absolutely amazing, it makes your page look good, keeps your explanation short, concise, and readable, and it also engages the audience&lt;br /&gt;
-	Each subheading under “Causes” is also very well outlined and explained, there is a lot of information there, and it is sure whatever information the reader may need would be found on your page as it has covered and explained a lot&lt;br /&gt;
Overall, all I have for your group are good comments, as I couldn’t think of anything else that you will might need to add or change on it at all! Your information extends beyond what is expected, but also extensive, concise, and, most importantly, extremely readable and engaging! GOOD WORK!&lt;br /&gt;
&lt;br /&gt;
====Group 5====&lt;br /&gt;
Your information extends beyond what is expected, but also extensive and readable and engaging. The page is formatted really well.&lt;br /&gt;
Pros&lt;br /&gt;
-	The structure of your page is really good. It flows well, all headings and subheadings were chosen really well, the use of diagrams keeps it engaging&lt;br /&gt;
-	Each subheading is chosen and highlighted well&lt;br /&gt;
-	A very extensive reference list, making it evident that you have researched your topic thoroughly!&lt;br /&gt;
Cons&lt;br /&gt;
-	Use of diagrams and photos in the introductory parts of your page will make your page much more engaging&lt;br /&gt;

=Female Infertility=&lt;br /&gt;
&lt;br /&gt;
[[File:Prevalence of Primary Infertility in 2010.jpeg|400px|thumb|right|Prevalence of Primary Infertility in 2010]]&lt;br /&gt;
&lt;br /&gt;
Female Infertility refers to the failure to conceive after one year of regular unprotected intercourse in females &amp;lt;ref name=one&amp;gt;&amp;lt;pubmed&amp;gt;26150870&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. In 2010, infertility affected 48.5 million couples world wide and the areas of highest prevalence included North Africa and Middle East, South Asia, Central/Eastern Europe and Central Asia and Sub-Saharan Africa &amp;lt;ref name=two&amp;gt;&amp;lt;pubmed&amp;gt;23271957&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. As there are several causes of female infertility, we will be focusing on infertility that is caused by '''Polycystic Ovarian Syndrome''' (PCOS), the most common cause of infertility that is medically treatable &amp;lt;ref name=one/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Polycystic Ovarian Syndrome==&lt;br /&gt;
Polycystic Ovarian Syndrome (PCOS) is a common endocrine disorder, affecting up to 20% of reproductive aged women [3] It is the most common cause of anovulatory infertility [1] which refers to infertility caused by the the absence of ovulation.&lt;br /&gt;
&lt;br /&gt;
=Causes=&lt;br /&gt;
&lt;br /&gt;
PCOS is a disorder of heterogeneous origin with unknown aetiology &amp;lt;ref name=four&amp;gt;&amp;lt;pubmed&amp;gt;21896560&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Studies have shown that both genetic and environmental factors contribute to the development of PCOS in women however there is limited research into the actual interactions between these two factors &amp;lt;ref name=un&amp;gt;&amp;lt;pubmed&amp;gt;17185788&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Genetic Factors===&lt;br /&gt;
&lt;br /&gt;
Despite the lack of information regarding its aetiology, there is increasing evidence for a genetic involvement in the endocrine disorder. Studies have shown that genes play an important role in contributing towards the clinical and biochemical features of the disease &amp;lt;ref name=four/&amp;gt;. This evidence includes the family clustering of cases, greater unanimity between monozygotic twins than heterozygotic twins and the ability to inherit endocrine and  metabolic features of PCOS &amp;lt;ref name=four/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
In one study, 115 sisters of women with PCOS were examined and results showed that half of these sisters had high testosterone levels, suggesting that hyperandrogenemia is a common trait with a dominant pattern of inheritance. These results strongly supported the idea of the familial clustering of biochemical features such as hyperandrogenism in first degree relatives &amp;lt;ref name=deux&amp;gt;&amp;lt;pubmed&amp;gt;9843997&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
Several genes have been considered to play an important role in the development of PCOS such as CYP11A, the insulin gene, the follistatin gene and a region near the insulin receptor gene. Yet, the evidence supporting most of these genes has been refuted by larger studies, except for the region near the insulin receptor gene &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
There has been strong evidence linking the gene CYP11a with hyperandrogenism in women with PCOS. &amp;lt;ref name=cinq&amp;gt;&amp;lt;pubmed&amp;gt;9147642&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; While it doesn't isolate this gene as the sole cause of PCOS, variation of the genotype at this locus contributes to production of excess androgen &amp;lt;ref name=h4&amp;gt;&amp;lt;pubmed&amp;gt;7962289&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Studies have also shown that there is strong evidence for linkage between the alleles at the Variable Number Tandem Repeats (VNTR) which is situated 5' to the insulin gene and PCOS. The data from the study suggests that it is a very susceptible region in PCOS and also may play a role in the development of hyperinsulinaemia &amp;lt;ref name=trois&amp;gt;&amp;lt;pubmed&amp;gt;9455828&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
===Environmental Factors===&lt;br /&gt;
The prevalence of PCOS in populations where there has been a constant gene pool indicates that environmental factors play a significant role in the aetiology of PCOS.&lt;br /&gt;
&lt;br /&gt;
===Obesity and Diet===&lt;br /&gt;
Obesity is the major environmental factor driving the development of PCOS in susceptible individuals. The rising rates of PCOS have been paralleled by the widespread emergence of obesity and type 2 diabetes which are prevalent in developed countries. The risk of developing PCOS from obesity is compounded by  poor dietary choices and lack of physical activity which has begun to characterise the lifestyle in developed countries &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Medication===&lt;br /&gt;
Studies have shown that valproic acid in medication used to treat epilepsy and bipolar disorders contributes to the development of PCOS. Women with these disorders  may develop the typical features of PCOS such as polycystic ovaries, anovulation, hyperandrogenism and obesity &amp;lt;ref name=quartre&amp;gt;&amp;lt;pubmed&amp;gt;8413434&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Recent studies also suggest that the weight gain from medication is significant as it can lead to the development of PCOS &amp;lt;ref name=deux/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=Pathogenesis=&lt;br /&gt;
&lt;br /&gt;
The pathogenesis of polycystic ovarian syndrome is poorly understood, however it is believed that insulin resistance and excess androgens such as testosterone play a fundamental role.&lt;br /&gt;
Underlying factors such as obesity and genetic predispositions likely contribute to the onset of polycystic ovarian syndrome through the development of a combination of hyperinsulinemia and hyperandrogenemia.&amp;lt;ref name=eleven&amp;gt;&amp;lt;pubmed&amp;gt;PMC4556908&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Hyperinsulinemia&amp;lt;/u&amp;gt;===&lt;br /&gt;
&lt;br /&gt;
Hyperinsulinemia is a term that defines the presence of excessive amounts of insulin in the blood relative to the amount of glucose. &amp;lt;ref name=fourteen&amp;gt;&amp;lt;pubmed&amp;gt;PMC4114053&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; This phenomenon is typically associated with obesity and excess adipose tissue, both of which are associated with insulin resistance. In order to overcome this resistance, insulin secretion is increased in an attempt to normalise blood glucose levels, thereby leading to hyperinsulineamia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC2782313&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; Excessive levels of insulin typically cause disruption to the hypothalamus-hypophysis-ovary axis whilst insulin resistance in ovarian tissues leads to decreased metabolic signalling. However, steroidogenic activity is largely unaffected by the impaired metabolic signalling, thereby paving the way androgens to become more effect and paving the way towards hyperandrogenemia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
[[File:Patholophysiology of Polycystic Ovarian Syndrome.jpg|500px|thumb|left|The impact of hyperinsulinemia and hyperandrogenemia on the development of polycystic ovarian syndrome]]&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Hyperandrogenemia&amp;lt;/u&amp;gt;===&lt;br /&gt;
&lt;br /&gt;
Hyperandrogenemia is a hallmark of the development of polycystic ovarian syndrome, with 80% of women presenting with excess androgen also having polycystic ovaries.&amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; The disruption of the hypothalamus hypophysis ovary axis as a result of hyperinsulinemia increases the release of GnRH and LH, leading to increased androgen production in the ovarian theca cells. Hyperandrogenemia decreases the feedback sensitivity of both estradiol and progesterone within gonadotropic hypothalmic cells. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; A deficiency of FSH is observed and correlates with the increased secretion of GnRH and LH. As a result of this deficiency, graunlosa  cell aromatisation to oestrogens as well as follicle maturation and ovulation will be drastically impaired.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3453528&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
As a consequence of the impairment of follicle maturation, small antral follicles will accumulate within the periphery of the ovary and develop a cystic morphology. Ovulation will be unable to occur due to the absence of mature follicles, culminating in infertility.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4562327&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Hyperandrogenism&amp;lt;/u&amp;gt;===&lt;br /&gt;
&lt;br /&gt;
====Animal Models====&lt;br /&gt;
&lt;br /&gt;
Studies conducted on female rhesus monkeys have supported evidence for the foetal origins of the clinical features of PCOS &amp;lt;ref name=h1&amp;gt;&amp;lt;pubmed&amp;gt;18406243&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.  It has been shown that in human females, an excess of androgen exposure at any stage from the development of the ovaries to the onset of puberty manifests as characteristic features of PCOS, such as resistance to insulin and Luteinising Hormone (LH) hypersecretion. After exposure to levels of testosterone matching those of fetal males, in utero, female rhesus monkeys were found to display the clinical and biochemical features typical of PCOS such as hypersecretion of LH and abnormal insulin action. These results correlated to those of similar studies conducted on sheep, where the pregnant ewe was exposed to excessive levels of testosterone and LH secretion and abnormality in ovarian cycles were again prominent features &amp;lt;ref name=sheep&amp;gt;Padmanabhan V, Evans NP, Taylor JA, Robinson JE1997 '''Prenatal exposure to  androgens  leads  to  the  development  of  cystic  ovaries  in  the  sheep'''. Biol Reprod 56:194&amp;lt;/ref&amp;gt;. While these studies indicate that similar biochemical and clinical manifestations in humans originate from excess androgen exposure of the female fetus, it must be noted that it is very unlikely for any excess androgen production to be passed across the placenta from the mother to her daughter. This is because mechanisms such as androgen binding proteins and placental metabolism of androgen prevent excess androgen entering the circulation of the fetus &amp;lt;ref name=h2&amp;gt;&amp;lt;pubmed&amp;gt;12098657&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
====Cell Culture Models====&lt;br /&gt;
&lt;br /&gt;
While studies have shown that the adrenal could be a source of excess androgen such as the adrenal &amp;lt;ref name=h3&amp;gt;&amp;lt;pubmed&amp;gt;7962325&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;, they were followed by various studies using cell culture models which demonstrated that the ovary was the major source of excess androgen &amp;lt;ref name=h4/&amp;gt; &amp;lt;ref name=h5&amp;gt;&amp;lt;pubmed&amp;gt;9302378&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. ''In vitro'' studies have shown that the production of steroids is abnormal in theca cells &amp;lt;ref name=h3/&amp;gt;. In women affected by PCOS, stimulation by human chorionic gonadotrophin (hCG) is followed by an increase in thecal steroid production after suppression of LH by a GnRH analogue &amp;lt;ref name=h5/&amp;gt;. Theca cells cultured from polycystic ovaries produce 20 times as much androstenedione as those from normal ovaries &amp;lt;ref name=h4/&amp;gt; with increased expression of mRNA for enzymes responsible for making steroids also reported in following studies. &amp;lt;ref name=h6&amp;gt;&amp;lt;pubmed&amp;gt;10852468&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; These results have prompted many studies on genes encoding these steroidogeneic enzymes.&lt;br /&gt;
&lt;br /&gt;

===&amp;lt;u&amp;gt;The Genetics of Infertility: Current Status of the Field&amp;lt;/u&amp;gt;===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3885174&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article attempted to determine the role that genetics plays in female infertility. It was noted that several prominent causes of female infertility such as Galactosemia and Primary Ovarian Failure (POF) were associated with specific genes, with the GALT gene contributing to the former condition and the FMR1 gene contributing to the latter.&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Causes of Sterility in Bosnia-Herzegovina Population&amp;lt;/u&amp;gt;===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC4499307&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
The study conducted as laid out in this article examined the causes of female sterility in the Bosnia-Herzegovina population. Married participants were arranged into various groups based upon their age. The experiment came to the conclusion that in approximately 42% of infertile married couples, female sterility was the primary cause. The two primary causes of female infertility were tubal deficiencies (31% of cases) and Diminished Ovarian Reserves (38% of cases)&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Epidemiology, diagnosis, and management of polycystic ovary syndrome&amp;lt;/u&amp;gt;===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This research article examines the causes of polycystic ovary syndrome (POS), a common cause of infertility in women. The article concluded that 50-70% of women suffer from insulin resistance secondary to Type 2 Diabetes and in many cases obseity, which may contribute partially to POS. Furthermore, 85-90% of women with oligomenorrhea also had POS, suggesting that it is an underlying cause. However, the exact pathophysiology of POS was not determined.&lt;br /&gt;
&lt;br /&gt;
=Signs and Symptoms=&lt;br /&gt;
&lt;br /&gt;
The symptoms of PCOS are different for each women. The three cardinal signs of PCOS are hyperandrogenism, polycystic ovaries and ovarian dysfunction &amp;lt;ref name=sign1&amp;gt;&amp;lt;pubmed&amp;gt;14688154&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Common clinical symptoms include &amp;lt;ref&amp;gt; Women's Heath, U.S. Department of Health and Human Services ,[ http://www.womenshealth.gov/publications/our-publications/fact-sheet/polycystic-ovary-syndrome.html#d ], 'Polycystic ovary syndrome (PCOS) fact sheet'&amp;lt;/ref&amp;gt; ;&lt;br /&gt;
&lt;br /&gt;
* Infertility- due to anovulation caused by PCOS. &lt;br /&gt;
* Irregular Menstrual Cycles&lt;br /&gt;
* Hirsutism&lt;br /&gt;
* Ovarian Cysts&lt;br /&gt;
* Obesity&lt;br /&gt;
* Male Pattern Baldness&lt;br /&gt;
* Skin Tags&lt;br /&gt;
* Pelvic Pain&lt;br /&gt;
&lt;br /&gt;
Along with obesity, PCOS is also associated with other metabolic issues such as insulin resistance, hyperinsulinemia and type 2 diabetes mellitus. It has also been associated with cardiovascular problems and cancers of the breast and endometrium &amp;lt;ref name=sign3&amp;gt;&amp;lt;pubmed&amp;gt;PMC4341818&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=Diagnosis=&lt;br /&gt;
&lt;br /&gt;
A major diagnostic tool for PCOS is a pelvic ultrasound, but PCOS diagnosis cannot be completely dependent on just pelvic ultrasounds. A patient with PCOS may not necessarily have polycystic ovaries, and those with ovarian cysts may not necessarily have PCOS. A range of diagnostic assessments and associated symptoms have to be thoroughly investigated.&lt;br /&gt;
&lt;br /&gt;
===Medical history and examination===&lt;br /&gt;
Clinical questions are asked or filled out in the form of a questionnaire to assess and assist in the diagnosis of PCOS. Studies show that those with a history:&lt;br /&gt;
*infrequent and irregular menstruation&lt;br /&gt;
*hirsutism (related to high levels of androgens in the blood – hyperandrogenism)&lt;br /&gt;
*obesity&lt;br /&gt;
*acne production &lt;br /&gt;
are at a higher predictive risk of PCOS. But questions regarding failed pregnancy attempts and history of nipple discharge proved no correlation in diagnosing PCOS. &amp;lt;ref&amp;gt; &amp;lt;pubmed&amp;gt; 17872783 &amp;lt;/pubmed&amp;gt; &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Blood Test===&lt;br /&gt;
A patient with elevated levels of androgens, a medical condition called &amp;lt;b&amp;gt;hyperandrogenism &amp;lt;/b&amp;gt;, is very highly likely to have PCOS. &amp;lt;ref&amp;gt; &amp;lt;pubmed&amp;gt; 20591140 &amp;lt;/pubmed&amp;gt; &amp;lt;/ref&amp;gt;&lt;br /&gt;
&amp;lt;b&amp;gt; Androgens &amp;lt;/b&amp;gt; , such as testosterone, and &amp;lt;b&amp;gt;free androgen index (FAI) &amp;lt;/b&amp;gt; are the two tests best used in diagnosing hyperandrogenism.&lt;br /&gt;
Androgen excess in PCOS is a result from increased synthesis and release of ovarian androgens. &amp;lt;b&amp;gt;Dehydroepiandrosterone sulfate &amp;lt;/b&amp;gt; (DHEA-S) levels are used as a biomarker for testing androgen levels, as it is made exclusively by the adrenal glands. DHEA-S levels of above 1890 micromol/L is extremely suggestive of hyperandrogenism. &amp;lt;ref&amp;gt; &amp;lt;pubmed&amp;gt; 18844715 &amp;lt;/pubmed&amp;gt; &amp;lt;/ref&amp;gt;&lt;br /&gt;
&amp;lt;b&amp;gt;Free androgen index (FAI) &amp;lt;/b&amp;gt; is the ratio of total testosterone measurement to levels of &amp;lt;b&amp;gt; sex hormone-binding globulin &amp;lt;/b&amp;gt; (SHBG). Those with PCOS will have high FAI, as this indicates a high ration of free testosterone in the body.&lt;br /&gt;
Other blood tests are also done to help exclude other predisposing factors such as levels of &amp;lt;b&amp;gt; Thyroid Stimulating Hormone &amp;lt;/b&amp;gt; (LSH) and &amp;lt;b&amp;gt; Follicle-stimulating hormone &amp;lt;/b&amp;gt; (FSH). An elevated ratio of LSH to FSH, of above 2:1 &amp;lt;ref&amp;gt; &amp;lt;pubmed&amp;gt; 14737959 &amp;lt;/pubmed&amp;gt; &amp;lt;/ref&amp;gt;, indicates a possibility, but not definitively, of PCOS.&lt;br /&gt;
The effect of &amp;lt;b&amp;gt; insulin &amp;lt;/b&amp;gt; on blood can also be tested for insulin resistance. Insulin resistance enhances androgen production and increases free androgen levels by reducing SHBG. This can used as an indication marker for the possibility of PCOS&lt;br /&gt;
A study in 2014 showed that &amp;lt;b&amp;gt; Anti-Müllerian hormone &amp;lt;/b&amp;gt; (AMH) is found to be elevated in patients with PCOS &amp;lt;ref&amp;gt; &amp;lt;pubmed&amp;gt; 24821925 &amp;lt;/pubmed&amp;gt; &amp;lt;/ref&amp;gt;, giving rise to its potential clinical implication in diagnosing PCOS. AMH is exclusively produced in ovarian follicles, with individual AMH concentration reflecting the quantity of remaining primordial follicles and measure of ovarian reserve. &lt;br /&gt;
&lt;br /&gt;
===Gynecologic ultrasonography===&lt;br /&gt;
Gynecologic ultrasonography is a pelvic ultrasound, specifically to the female pelvic region, with regards to the uterus, ovaries and the fallopian tube. The examination can be performed by transabdominal ultrasonography, with a full bladder, or transvaginal ultrasonography with a vaginal transducer. Typically transvaginal imaging shows a better and clearer image than transabdominal ultrasonography, as it uses higher frequency imaging, but is limited to areas it can reach. In the case of PCOS, both techniques can provide an image of the ovaries. Studies suggest that if more than 25 follicles are seen in an ovary, predominantly in the periphery, in women between 18-35 years, it is described to have a polycystic ovarian morphology. &amp;lt;ref&amp;gt; &amp;lt;pubmed&amp;gt; 24345633 &amp;lt;/pubmed&amp;gt; &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Magnetic Resonance Imaging===&lt;br /&gt;
Ovaries can also be seen on MRIs. On MRIs, PCOS is characterized by numberous peripheral cysts where the ovaries affected to be slightly larger than normal. Although MRI is seen to be effective in ovarian imaging, the finding of peripheral ovarian cysts in MRIsmay not be PCOS specific. &amp;lt;ref&amp;gt; &amp;lt;pubmed&amp;gt; 8888256 &amp;lt;/pubmed&amp;gt; &amp;lt;/ref&amp;gt; But studies have seen that MR imaging in adolescence uncover distinct differences between young patients with and without PCOS &amp;lt;ref&amp;gt; &amp;lt;pubmed&amp;gt; 23292744 &amp;lt;/pubmed&amp;gt; &amp;lt;/ref&amp;gt;, with also great diagnostic sensitivity with patients between the age of 21-30 &amp;lt;ref&amp;gt; &amp;lt;pubmed&amp;gt; 19241321 &amp;lt;/pubmed&amp;gt; &amp;lt;/ref&amp;gt;, providing assistance of imagery in patients whom may be opposed to transvaginal ultrasounds.&lt;br /&gt;
&lt;br /&gt;
=Prevention=&lt;br /&gt;
&lt;br /&gt;
==Impact of physical activity on ovarian reserve markers in normal, overweight and obese reproductive age women==&lt;br /&gt;
&amp;lt;pubmed&amp;gt;25509968&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study focuses on the effect of physical activity on fertility in three groups of women at reproductive age; normal, overweight and obese. The results from the study suggest that there was a marked improvement in fertility as shown by the ovarian reserve markers for all 3 groups, however it was most significant in the overweight and obese groups. This study is relevant to our project as it gives an insight into the preventative measures that can be taken for infertility. &lt;br /&gt;
&lt;br /&gt;
==Risk factors of polycystic ovarian syndrome among Li People==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;26276294&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study examined the risk factors entailed in Polycystic Ovarian Syndrdome (PCOS) amoung Li people. Using the method of a case control study, questionnaires were given to female Li people with and without PCOS. Analysis of the questionnaires showed that family history of diabetes, family history of infertility, bad mood, lack of physical exercise are all high risk factors of PCOS. As a result, management of these risk factors can be taken into consideration when preventing infertility through PCOS.&lt;br /&gt;
&lt;br /&gt;
==Vitamin D and female fertility==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;24717915&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article is a review focusing on research regarding Vitamin D and fertility over the past year. The review found that the levels of Vitamin D is crucial for women undergoing in-vitro fertilisation. It  was also found that Vitamin D was beneficial for women with PCOS and carried a protective effect against endometriosis. These observations suggest that having sufficient Vitamin D in your body can be preventative for problems associated with fertility.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Treatment=&lt;br /&gt;
There currently is no cure for PCOS. Treatment maybe involve lifestyle changes or hormonal augmentation in regulating periods, hirsutism, and acne, in addition to regulating androgen levels.&lt;br /&gt;
===Current Treatments===&lt;br /&gt;
&lt;br /&gt;

| '''CURRENT TREATMENT'''&lt;br /&gt;
| '''DISADVANTAGES'''&lt;br /&gt;
|-&lt;br /&gt;
| General Practitioners tend to prescribe oral anti-oestrogens, most commonly the contraceptive pill, to restore ovulation.&lt;br /&gt;
| This method only has a 50% success rate in PCOS patients. It does not directly increase fertility rates, but restores the menstrual cycle.&lt;br /&gt;
 &lt;br /&gt;
|-bgcolor=&amp;quot;FAF5FF&amp;quot;&lt;br /&gt;
| Lifestyle changes are highly encouraged by medical practitioners. Diet and exercise regimes can be designed with a dietitian or nutritionist. &lt;br /&gt;
| Exercise and diet plans do not directly increase fertility. They are designed to enhance weight loss, which in some patients can encourage normal hormone levels from the pituitary and thyroid. &lt;br /&gt;

| Clomiphene citrate administration (generally in pill form, as prescribed by a GP). Such pills stimulate the pituitary gland to release GnRH to simulate ovulation (with a 72% success rate in the ___ trial). &lt;br /&gt;
| Clomiphene can cause multiple side effects, most notably abnormal uterine bleeding and pelvic pain to due enlargement of the ovaries. &lt;br /&gt;
&lt;br /&gt;
Thus, it cannot be as frequently prescribed as the contraceptive pill, and careful patient monitoring is imperative. &lt;br /&gt;

&lt;br /&gt;
===New Trials===&lt;br /&gt;
&lt;br /&gt;
Some studies have found that regular Selenium supplements can encourage fertility among PCOS patients. The program, which is still in its early trial period, requires women to consume selenium tablets for 8 weeks. This study has found a significant decrease in dehydroepiandrosterone (DHEA) levels in patients, thus reducing excessive hair growth associated with PCOS. A direct link to increased fertility is yet to be established, and thus further testing is required.&lt;br /&gt;

=Female Infertility=&lt;br /&gt;
&lt;br /&gt;
[[File:Prevalence of Primary Infertility in 2010.jpeg|400px|thumb|right|Prevalence of Primary Infertility in 2010]]&lt;br /&gt;
&lt;br /&gt;
Female Infertility refers to the failure to conceive after one year of regular unprotected intercourse in females &amp;lt;ref name=one&amp;gt;&amp;lt;pubmed&amp;gt;26150870&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. In 2010, infertility affected 48.5 million couples world wide and the areas of highest prevalence included North Africa and Middle East, South Asia, Central/Eastern Europe and Central Asia and Sub-Saharan Africa &amp;lt;ref name=two&amp;gt;&amp;lt;pubmed&amp;gt;23271957&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. As there are several causes of female infertility, we will be focusing on infertility that is caused by '''Polycystic Ovarian Syndrome''' (PCOS), the most common cause of infertility that is medically treatable &amp;lt;ref name=one/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Polycystic Ovarian Syndrome==&lt;br /&gt;
Polycystic Ovarian Syndrome (PCOS) is a common endocrine disorder, affecting up to 20% of reproductive aged women [3] It is the most common cause of anovulatory infertility [1] which refers to infertility caused by the the absence of ovulation.&lt;br /&gt;
&lt;br /&gt;
=Causes=&lt;br /&gt;
&lt;br /&gt;
PCOS is a disorder of heterogeneous origin with unknown aetiology &amp;lt;ref name=four&amp;gt;&amp;lt;pubmed&amp;gt;21896560&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Studies have shown that both genetic and environmental factors contribute to the development of PCOS in women however there is limited research into the actual interactions between these two factors &amp;lt;ref name=un&amp;gt;&amp;lt;pubmed&amp;gt;17185788&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Genetic Factors===&lt;br /&gt;
&lt;br /&gt;
Despite the lack of information regarding its aetiology, there is increasing evidence for a genetic involvement in the endocrine disorder. Studies have shown that genes play an important role in contributing towards the clinical and biochemical features of the disease &amp;lt;ref name=four/&amp;gt;. This evidence includes the family clustering of cases, greater unanimity between monozygotic twins than heterozygotic twins and the ability to inherit endocrine and  metabolic features of PCOS &amp;lt;ref name=four/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
In one study, 115 sisters of women with PCOS were examined and results showed that half of these sisters had high testosterone levels, suggesting that hyperandrogenemia is a common trait with a dominant pattern of inheritance. These results strongly supported the idea of the familial clustering of biochemical features such as hyperandrogenism in first degree relatives &amp;lt;ref name=deux&amp;gt;&amp;lt;pubmed&amp;gt;9843997&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
Several genes have been considered to play an important role in the development of PCOS such as CYP11A, the insulin gene, the follistatin gene and a region near the insulin receptor gene. Yet, the evidence supporting most of these genes has been refuted by larger studies, except for the region near the insulin receptor gene &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
There has been strong evidence linking the gene CYP11a with hyperandrogenism in women with PCOS. &amp;lt;ref name=cinq&amp;gt;&amp;lt;pubmed&amp;gt;9147642&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; While it doesn't isolate this gene as the sole cause of PCOS, variation of the genotype at this locus contributes to production of excess androgen &amp;lt;ref name=h4&amp;gt;&amp;lt;pubmed&amp;gt;7962289&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Studies have also shown that there is strong evidence for linkage between the alleles at the Variable Number Tandem Repeats (VNTR) which is situated 5' to the insulin gene and PCOS. The data from the study suggests that it is a very susceptible region in PCOS and also may play a role in the development of hyperinsulinaemia &amp;lt;ref name=trois&amp;gt;&amp;lt;pubmed&amp;gt;9455828&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
===Environmental Factors===&lt;br /&gt;
The prevalence of PCOS in populations where there has been a constant gene pool indicates that environmental factors play a significant role in the aetiology of PCOS.&lt;br /&gt;
&lt;br /&gt;
===Obesity and Diet===&lt;br /&gt;
Obesity is the major environmental factor driving the development of PCOS in susceptible individuals. The rising rates of PCOS have been paralleled by the widespread emergence of obesity and type 2 diabetes which are prevalent in developed countries. The risk of developing PCOS from obesity is compounded by  poor dietary choices and lack of physical activity which has begun to characterise the lifestyle in developed countries &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Medication===&lt;br /&gt;
Studies have shown that valproic acid in medication used to treat epilepsy and bipolar disorders contributes to the development of PCOS. Women with these disorders  may develop the typical features of PCOS such as polycystic ovaries, anovulation, hyperandrogenism and obesity &amp;lt;ref name=quartre&amp;gt;&amp;lt;pubmed&amp;gt;8413434&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Recent studies also suggest that the weight gain from medication is significant as it can lead to the development of PCOS &amp;lt;ref name=deux/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=Pathogenesis=&lt;br /&gt;
&lt;br /&gt;
The pathogenesis of polycystic ovarian syndrome is poorly understood, however it is believed that insulin resistance and excess androgens such as testosterone play a fundamental role.&lt;br /&gt;
Underlying factors such as obesity and genetic predispositions likely contribute to the onset of polycystic ovarian syndrome through the development of a combination of hyperinsulinemia and hyperandrogenemia.&amp;lt;ref name=eleven&amp;gt;&amp;lt;pubmed&amp;gt;PMC4556908&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Hyperinsulinemia&amp;lt;/u&amp;gt;===&lt;br /&gt;
&lt;br /&gt;
Hyperinsulinemia is a term that defines the presence of excessive amounts of insulin in the blood relative to the amount of glucose. &amp;lt;ref name=fourteen&amp;gt;&amp;lt;pubmed&amp;gt;PMC4114053&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; This phenomenon is typically associated with obesity and excess adipose tissue, both of which are associated with insulin resistance. In order to overcome this resistance, insulin secretion is increased in an attempt to normalise blood glucose levels, thereby leading to hyperinsulineamia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC2782313&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; Excessive levels of insulin typically cause disruption to the hypothalamus-hypophysis-ovary axis whilst insulin resistance in ovarian tissues leads to decreased metabolic signalling. However, steroidogenic activity is largely unaffected by the impaired metabolic signalling, thereby paving the way androgens to become more effect and paving the way towards hyperandrogenemia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
[[File:Patholophysiology of Polycystic Ovarian Syndrome.jpg|500px|thumb|left|The impact of hyperinsulinemia and hyperandrogenemia on the development of polycystic ovarian syndrome]]&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Hyperandrogenemia&amp;lt;/u&amp;gt;===&lt;br /&gt;
&lt;br /&gt;
Hyperandrogenemia is a hallmark of the development of polycystic ovarian syndrome, with 80% of women presenting with excess androgen also having polycystic ovaries.&amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; The disruption of the hypothalamus hypophysis ovary axis as a result of hyperinsulinemia increases the release of GnRH and LH, leading to increased androgen production in the ovarian theca cells. Hyperandrogenemia decreases the feedback sensitivity of both estradiol and progesterone within gonadotropic hypothalmic cells. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; A deficiency of FSH is observed and correlates with the increased secretion of GnRH and LH. As a result of this deficiency, graunlosa  cell aromatisation to oestrogens as well as follicle maturation and ovulation will be drastically impaired.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3453528&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
As a consequence of the impairment of follicle maturation, small antral follicles will accumulate within the periphery of the ovary and develop a cystic morphology. Ovulation will be unable to occur due to the absence of mature follicles, culminating in infertility.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4562327&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Hyperandrogenism&amp;lt;/u&amp;gt;===&lt;br /&gt;
&lt;br /&gt;
====Animal Models====&lt;br /&gt;
&lt;br /&gt;
Studies conducted on female rhesus monkeys have supported evidence for the foetal origins of the clinical features of PCOS &amp;lt;ref name=h1&amp;gt;&amp;lt;pubmed&amp;gt;18406243&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.  It has been shown that in human females, an excess of androgen exposure at any stage from the development of the ovaries to the onset of puberty manifests as characteristic features of PCOS, such as resistance to insulin and Luteinising Hormone (LH) hypersecretion. After exposure to levels of testosterone matching those of fetal males, in utero, female rhesus monkeys were found to display the clinical and biochemical features typical of PCOS such as hypersecretion of LH and abnormal insulin action. These results correlated to those of similar studies conducted on sheep, where the pregnant ewe was exposed to excessive levels of testosterone and LH secretion and abnormality in ovarian cycles were again prominent features &amp;lt;ref name=sheep&amp;gt;Padmanabhan V, Evans NP, Taylor JA, Robinson JE1997 '''Prenatal exposure to  androgens  leads  to  the  development  of  cystic  ovaries  in  the  sheep'''. Biol Reprod 56:194&amp;lt;/ref&amp;gt;. While these studies indicate that similar biochemical and clinical manifestations in humans originate from excess androgen exposure of the female fetus, it must be noted that it is very unlikely for any excess androgen production to be passed across the placenta from the mother to her daughter. This is because mechanisms such as androgen binding proteins and placental metabolism of androgen prevent excess androgen entering the circulation of the fetus &amp;lt;ref name=h2&amp;gt;&amp;lt;pubmed&amp;gt;12098657&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
====Cell Culture Models====&lt;br /&gt;
&lt;br /&gt;
While studies have shown that the adrenal could be a source of excess androgen such as the adrenal &amp;lt;ref name=h3&amp;gt;&amp;lt;pubmed&amp;gt;7962325&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;, they were followed by various studies using cell culture models which demonstrated that the ovary was the major source of excess androgen &amp;lt;ref name=h4/&amp;gt; &amp;lt;ref name=h5&amp;gt;&amp;lt;pubmed&amp;gt;9302378&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. ''In vitro'' studies have shown that the production of steroids is abnormal in theca cells &amp;lt;ref name=h3/&amp;gt;. In women affected by PCOS, stimulation by human chorionic gonadotrophin (hCG) is followed by an increase in thecal steroid production after suppression of LH by a GnRH analogue &amp;lt;ref name=h5/&amp;gt;. Theca cells cultured from polycystic ovaries produce 20 times as much androstenedione as those from normal ovaries &amp;lt;ref name=h4/&amp;gt; with increased expression of mRNA for enzymes responsible for making steroids also reported in following studies. &amp;lt;ref name=h6&amp;gt;&amp;lt;pubmed&amp;gt;10852468&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; These results have prompted many studies on genes encoding these steroidogeneic enzymes.&lt;br /&gt;
&lt;br /&gt;

===&amp;lt;u&amp;gt;The Genetics of Infertility: Current Status of the Field&amp;lt;/u&amp;gt;===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3885174&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article attempted to determine the role that genetics plays in female infertility. It was noted that several prominent causes of female infertility such as Galactosemia and Primary Ovarian Failure (POF) were associated with specific genes, with the GALT gene contributing to the former condition and the FMR1 gene contributing to the latter.&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Causes of Sterility in Bosnia-Herzegovina Population&amp;lt;/u&amp;gt;===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC4499307&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
The study conducted as laid out in this article examined the causes of female sterility in the Bosnia-Herzegovina population. Married participants were arranged into various groups based upon their age. The experiment came to the conclusion that in approximately 42% of infertile married couples, female sterility was the primary cause. The two primary causes of female infertility were tubal deficiencies (31% of cases) and Diminished Ovarian Reserves (38% of cases)&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Epidemiology, diagnosis, and management of polycystic ovary syndrome&amp;lt;/u&amp;gt;===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This research article examines the causes of polycystic ovary syndrome (POS), a common cause of infertility in women. The article concluded that 50-70% of women suffer from insulin resistance secondary to Type 2 Diabetes and in many cases obseity, which may contribute partially to POS. Furthermore, 85-90% of women with oligomenorrhea also had POS, suggesting that it is an underlying cause. However, the exact pathophysiology of POS was not determined.&lt;br /&gt;
&lt;br /&gt;
=Signs and Symptoms=&lt;br /&gt;
&lt;br /&gt;
The symptoms of PCOS are different for each women. The three cardinal signs of PCOS are hyperandrogenism, polycystic ovaries and ovarian dysfunction &amp;lt;ref name=sign1&amp;gt;&amp;lt;pubmed&amp;gt;14688154&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Common clinical symptoms include &amp;lt;ref&amp;gt; Women's Heath, U.S. Department of Health and Human Services ,[ http://www.womenshealth.gov/publications/our-publications/fact-sheet/polycystic-ovary-syndrome.html#d ], 'Polycystic ovary syndrome (PCOS) fact sheet'&amp;lt;/ref&amp;gt; ;&lt;br /&gt;
&lt;br /&gt;
* Infertility- due to anovulation caused by PCOS. &lt;br /&gt;
* Irregular Menstrual Cycles&lt;br /&gt;
* Hirsutism&lt;br /&gt;
* Ovarian Cysts&lt;br /&gt;
* Obesity&lt;br /&gt;
* Male Pattern Baldness&lt;br /&gt;
* Skin Tags&lt;br /&gt;
* Pelvic Pain&lt;br /&gt;
&lt;br /&gt;
Along with obesity, PCOS is also associated with other metabolic issues such as insulin resistance, hyperinsulinemia and type 2 diabetes mellitus. It has also been associated with cardiovascular problems and cancers of the breast and endometrium &amp;lt;ref name=sign3&amp;gt;&amp;lt;pubmed&amp;gt;PMC4341818&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=Diagnosis=&lt;br /&gt;
&lt;br /&gt;
A major diagnostic tool for PCOS is a pelvic ultrasound, but PCOS diagnosis cannot be completely dependent on just pelvic ultrasounds. A patient with PCOS may not necessarily have polycystic ovaries, and those with ovarian cysts may not necessarily have PCOS. A range of diagnostic assessments and associated symptoms have to be thoroughly investigated.&lt;br /&gt;
&lt;br /&gt;
===Medical history and examination===&lt;br /&gt;
Clinical questions are asked or filled out in the form of a questionnaire to assess and assist in the diagnosis of PCOS. Studies show that those with a history:&lt;br /&gt;
*infrequent and irregular menstruation&lt;br /&gt;
*hirsutism (related to high levels of androgens in the blood – hyperandrogenism)&lt;br /&gt;
*obesity&lt;br /&gt;
*acne production &lt;br /&gt;
are at a higher predictive risk of PCOS. But questions regarding failed pregnancy attempts and history of nipple discharge proved no correlation in diagnosing PCOS. &amp;lt;ref&amp;gt; &amp;lt;pubmed&amp;gt; 17872783 &amp;lt;/pubmed&amp;gt; &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Blood Test===&lt;br /&gt;
A patient with elevated levels of androgens, a medical condition called &amp;lt;b&amp;gt;hyperandrogenism &amp;lt;/b&amp;gt;, is very highly likely to have PCOS. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/20591140 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&amp;lt;b&amp;gt; Androgens &amp;lt;/b&amp;gt; , such as testosterone, and &amp;lt;b&amp;gt;free androgen index (FAI) &amp;lt;/b&amp;gt; are the two tests best used in diagnosing hyperandrogenism.&lt;br /&gt;
Androgen excess in PCOS is a result from increased synthesis and release of ovarian androgens. &amp;lt;b&amp;gt;Dehydroepiandrosterone sulfate &amp;lt;/b&amp;gt; (DHEA-S) levels are used as a biomarker for testing androgen levels, as it is made exclusively by the adrenal glands. DHEA-S levels of above 1890 micromol/L is extremely suggestive of hyperandrogenism. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/18844715 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&amp;lt;b&amp;gt;Free androgen index (FAI) &amp;lt;/b&amp;gt; is the ratio of total testosterone measurement to levels of &amp;lt;b&amp;gt; sex hormone-binding globulin &amp;lt;/b&amp;gt; (SHBG). Those with PCOS will have high FAI, as this indicates a high ration of free testosterone in the body.&lt;br /&gt;
Other blood tests are also done to help exclude other predisposing factors such as levels of &amp;lt;b&amp;gt; Thyroid Stimulating Hormone &amp;lt;/b&amp;gt; (LSH) and &amp;lt;b&amp;gt; Follicle-stimulating hormone &amp;lt;/b&amp;gt; (FSH). An elevated ratio of LSH to FSH, of above 2:1 &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/14737959 &amp;lt;/ref&amp;gt;, indicates a possibility, but not definitively, of PCOS.&lt;br /&gt;
The effect of &amp;lt;b&amp;gt; insulin &amp;lt;/b&amp;gt; on blood can also be tested for insulin resistance. Insulin resistance enhances androgen production and increases free androgen levels by reducing SHBG. This can used as an indication marker for the possibility of PCOS&lt;br /&gt;
A study in 2014 showed that &amp;lt;b&amp;gt; Anti-Müllerian hormone &amp;lt;/b&amp;gt; (AMH) is found to be elevated in patients with PCOS &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24821925 &amp;lt;/ref&amp;gt;, giving rise to its potential clinical implication in diagnosing PCOS. AMH is exclusively produced in ovarian follicles, with individual AMH concentration reflecting the quantity of remaining primordial follicles and measure of ovarian reserve. &lt;br /&gt;
&lt;br /&gt;
===Gynecologic ultrasonography===&lt;br /&gt;
Gynecologic ultrasonography is a pelvic ultrasound, specifically to the female pelvic region, with regards to the uterus, ovaries and the fallopian tube. The examination can be performed by transabdominal ultrasonography, with a full bladder, or transvaginal ultrasonography with a vaginal transducer. Typically transvaginal imaging shows a better and clearer image than transabdominal ultrasonography, as it uses higher frequency imaging, but is limited to areas it can reach. In the case of PCOS, both techniques can provide an image of the ovaries. Studies suggest that if more than 25 follicles are seen in an ovary, predominantly in the periphery, in women between 18-35 years, it is described to have a polycystic ovarian morphology. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24345633 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Magnetic Resonance Imaging===&lt;br /&gt;
Ovaries can also be seen on MRIs. On MRIs, PCOS is characterized by numberous peripheral cysts where the ovaries affected to be slightly larger than normal. Although MRI is seen to be effective in ovarian imaging, the finding of peripheral ovarian cysts in MRIsmay not be PCOS specific. &amp;lt;ref&amp;gt;  http://www.ncbi.nlm.nih.gov/pubmed/8888256 &amp;lt;/ref&amp;gt; But studies have seen that MR imaging in adolescence uncover distinct differences between young patients with and without PCOS &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/23292744 &amp;lt;/ref&amp;gt;, with also great diagnostic sensitivity with patients between the age of 21-30 &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/19241321 &amp;lt;/ref&amp;gt;, providing assistance of imagery in patients whom may be opposed to transvaginal ultrasounds.&lt;br /&gt;
&lt;br /&gt;
=Prevention=&lt;br /&gt;
&lt;br /&gt;
==Impact of physical activity on ovarian reserve markers in normal, overweight and obese reproductive age women==&lt;br /&gt;
&amp;lt;pubmed&amp;gt;25509968&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study focuses on the effect of physical activity on fertility in three groups of women at reproductive age; normal, overweight and obese. The results from the study suggest that there was a marked improvement in fertility as shown by the ovarian reserve markers for all 3 groups, however it was most significant in the overweight and obese groups. This study is relevant to our project as it gives an insight into the preventative measures that can be taken for infertility. &lt;br /&gt;
&lt;br /&gt;
==Risk factors of polycystic ovarian syndrome among Li People==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;26276294&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study examined the risk factors entailed in Polycystic Ovarian Syndrdome (PCOS) amoung Li people. Using the method of a case control study, questionnaires were given to female Li people with and without PCOS. Analysis of the questionnaires showed that family history of diabetes, family history of infertility, bad mood, lack of physical exercise are all high risk factors of PCOS. As a result, management of these risk factors can be taken into consideration when preventing infertility through PCOS.&lt;br /&gt;
&lt;br /&gt;
==Vitamin D and female fertility==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;24717915&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article is a review focusing on research regarding Vitamin D and fertility over the past year. The review found that the levels of Vitamin D is crucial for women undergoing in-vitro fertilisation. It  was also found that Vitamin D was beneficial for women with PCOS and carried a protective effect against endometriosis. These observations suggest that having sufficient Vitamin D in your body can be preventative for problems associated with fertility.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Treatment=&lt;br /&gt;
There currently is no cure for PCOS. Treatment maybe involve lifestyle changes or hormonal augmentation in regulating periods, hirsutism, and acne, in addition to regulating androgen levels.&lt;br /&gt;
===Current Treatments===&lt;br /&gt;

| General Practitioners tend to prescribe oral anti-oestrogens, most commonly the contraceptive pill, to restore ovulation.&lt;br /&gt;
| This method only has a 50% success rate in PCOS patients. It does not directly increase fertility rates, but restores the menstrual cycle.&lt;br /&gt;

===New Trials===&lt;br /&gt;
&lt;br /&gt;
Some studies have found that regular Selenium supplements can encourage fertility among PCOS patients. The program, which is still in its early trial period, requires women to consume selenium tablets for 8 weeks. This study has found a significant decrease in dehydroepiandrosterone (DHEA) levels in patients, thus reducing excessive hair growth associated with PCOS. A direct link to increased fertility is yet to be established, and thus further testing is required.&lt;br /&gt;

=Female Infertility=&lt;br /&gt;
&lt;br /&gt;
[[File:Prevalence of Primary Infertility in 2010.jpeg|400px|thumb|right|Prevalence of Primary Infertility in 2010]]&lt;br /&gt;
&lt;br /&gt;
Female Infertility refers to the failure to conceive after one year of regular unprotected intercourse in females &amp;lt;ref name=one&amp;gt;&amp;lt;pubmed&amp;gt;26150870&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. In 2010, infertility affected 48.5 million couples world wide and the areas of highest prevalence included North Africa and Middle East, South Asia, Central/Eastern Europe and Central Asia and Sub-Saharan Africa &amp;lt;ref name=two&amp;gt;&amp;lt;pubmed&amp;gt;23271957&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. As there are several causes of female infertility, we will be focusing on infertility that is caused by '''Polycystic Ovarian Syndrome''' (PCOS), the most common cause of infertility that is medically treatable &amp;lt;ref name=one/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Polycystic Ovarian Syndrome==&lt;br /&gt;
Polycystic Ovarian Syndrome (PCOS) is a common endocrine disorder, affecting up to 20% of reproductive aged women [3] It is the most common cause of anovulatory infertility [1] which refers to infertility caused by the the absence of ovulation.&lt;br /&gt;
&lt;br /&gt;
=Causes=&lt;br /&gt;
&lt;br /&gt;
PCOS is a disorder of heterogeneous origin with unknown aetiology &amp;lt;ref name=four&amp;gt;&amp;lt;pubmed&amp;gt;21896560&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Studies have shown that both genetic and environmental factors contribute to the development of PCOS in women however there is limited research into the actual interactions between these two factors &amp;lt;ref name=un&amp;gt;&amp;lt;pubmed&amp;gt;17185788&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Genetic Factors===&lt;br /&gt;
&lt;br /&gt;
Despite the lack of information regarding its aetiology, there is increasing evidence for a genetic involvement in the endocrine disorder. Studies have shown that genes play an important role in contributing towards the clinical and biochemical features of the disease &amp;lt;ref name=four/&amp;gt;. This evidence includes the family clustering of cases, greater unanimity between monozygotic twins than heterozygotic twins and the ability to inherit endocrine and  metabolic features of PCOS &amp;lt;ref name=four/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
In one study, 115 sisters of women with PCOS were examined and results showed that half of these sisters had high testosterone levels, suggesting that hyperandrogenemia is a common trait with a dominant pattern of inheritance. These results strongly supported the idea of the familial clustering of biochemical features such as hyperandrogenism in first degree relatives &amp;lt;ref name=deux&amp;gt;&amp;lt;pubmed&amp;gt;9843997&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
Several genes have been considered to play an important role in the development of PCOS such as CYP11A, the insulin gene, the follistatin gene and a region near the insulin receptor gene. Yet, the evidence supporting most of these genes has been refuted by larger studies, except for the region near the insulin receptor gene &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
There has been strong evidence linking the gene CYP11a with hyperandrogenism in women with PCOS. &amp;lt;ref name=cinq&amp;gt;&amp;lt;pubmed&amp;gt;9147642&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; While it doesn't isolate this gene as the sole cause of PCOS, variation of the genotype at this locus contributes to production of excess androgen &amp;lt;ref name=h4&amp;gt;&amp;lt;pubmed&amp;gt;7962289&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Studies have also shown that there is strong evidence for linkage between the alleles at the Variable Number Tandem Repeats (VNTR) which is situated 5' to the insulin gene and PCOS. The data from the study suggests that it is a very susceptible region in PCOS and also may play a role in the development of hyperinsulinaemia &amp;lt;ref name=trois&amp;gt;&amp;lt;pubmed&amp;gt;9455828&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
===Environmental Factors===&lt;br /&gt;
The prevalence of PCOS in populations where there has been a constant gene pool indicates that environmental factors play a significant role in the aetiology of PCOS.&lt;br /&gt;
&lt;br /&gt;
===Obesity and Diet===&lt;br /&gt;
Obesity is the major environmental factor driving the development of PCOS in susceptible individuals. The rising rates of PCOS have been paralleled by the widespread emergence of obesity and type 2 diabetes which are prevalent in developed countries. The risk of developing PCOS from obesity is compounded by  poor dietary choices and lack of physical activity which has begun to characterise the lifestyle in developed countries &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Medication===&lt;br /&gt;
Studies have shown that valproic acid in medication used to treat epilepsy and bipolar disorders contributes to the development of PCOS. Women with these disorders  may develop the typical features of PCOS such as polycystic ovaries, anovulation, hyperandrogenism and obesity &amp;lt;ref name=quartre&amp;gt;&amp;lt;pubmed&amp;gt;8413434&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Recent studies also suggest that the weight gain from medication is significant as it can lead to the development of PCOS &amp;lt;ref name=deux/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=Pathogenesis=&lt;br /&gt;
&lt;br /&gt;
The pathogenesis of polycystic ovarian syndrome is poorly understood, however it is believed that insulin resistance and excess androgens such as testosterone play a fundamental role.&lt;br /&gt;
Underlying factors such as obesity and genetic predispositions likely contribute to the onset of polycystic ovarian syndrome through the development of a combination of hyperinsulinemia and hyperandrogenemia.&amp;lt;ref name=eleven&amp;gt;&amp;lt;pubmed&amp;gt;PMC4556908&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Hyperinsulinemia&amp;lt;/u&amp;gt;===&lt;br /&gt;
&lt;br /&gt;
Hyperinsulinemia is a term that defines the presence of excessive amounts of insulin in the blood relative to the amount of glucose. &amp;lt;ref name=fourteen&amp;gt;&amp;lt;pubmed&amp;gt;PMC4114053&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; This phenomenon is typically associated with obesity and excess adipose tissue, both of which are associated with insulin resistance. In order to overcome this resistance, insulin secretion is increased in an attempt to normalise blood glucose levels, thereby leading to hyperinsulineamia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC2782313&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; Excessive levels of insulin typically cause disruption to the hypothalamus-hypophysis-ovary axis whilst insulin resistance in ovarian tissues leads to decreased metabolic signalling. However, steroidogenic activity is largely unaffected by the impaired metabolic signalling, thereby paving the way androgens to become more effect and paving the way towards hyperandrogenemia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
[[File:Patholophysiology of Polycystic Ovarian Syndrome.jpg|500px|thumb|left|The impact of hyperinsulinemia and hyperandrogenemia on the development of polycystic ovarian syndrome]]&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Hyperandrogenemia&amp;lt;/u&amp;gt;===&lt;br /&gt;
&lt;br /&gt;
Hyperandrogenemia is a hallmark of the development of polycystic ovarian syndrome, with 80% of women presenting with excess androgen also having polycystic ovaries.&amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; The disruption of the hypothalamus hypophysis ovary axis as a result of hyperinsulinemia increases the release of GnRH and LH, leading to increased androgen production in the ovarian theca cells. Hyperandrogenemia decreases the feedback sensitivity of both estradiol and progesterone within gonadotropic hypothalmic cells. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; A deficiency of FSH is observed and correlates with the increased secretion of GnRH and LH. As a result of this deficiency, graunlosa  cell aromatisation to oestrogens as well as follicle maturation and ovulation will be drastically impaired.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3453528&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
As a consequence of the impairment of follicle maturation, small antral follicles will accumulate within the periphery of the ovary and develop a cystic morphology. Ovulation will be unable to occur due to the absence of mature follicles, culminating in infertility.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4562327&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Hyperandrogenism&amp;lt;/u&amp;gt;===&lt;br /&gt;
&lt;br /&gt;
====Animal Models====&lt;br /&gt;
&lt;br /&gt;
Studies conducted on female rhesus monkeys have supported evidence for the foetal origins of the clinical features of PCOS &amp;lt;ref name=h1&amp;gt;&amp;lt;pubmed&amp;gt;18406243&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.  It has been shown that in human females, an excess of androgen exposure at any stage from the development of the ovaries to the onset of puberty manifests as characteristic features of PCOS, such as resistance to insulin and Luteinising Hormone (LH) hypersecretion. After exposure to levels of testosterone matching those of fetal males, in utero, female rhesus monkeys were found to display the clinical and biochemical features typical of PCOS such as hypersecretion of LH and abnormal insulin action. These results correlated to those of similar studies conducted on sheep, where the pregnant ewe was exposed to excessive levels of testosterone and LH secretion and abnormality in ovarian cycles were again prominent features &amp;lt;ref name=sheep&amp;gt;Padmanabhan V, Evans NP, Taylor JA, Robinson JE1997 '''Prenatal exposure to  androgens  leads  to  the  development  of  cystic  ovaries  in  the  sheep'''. Biol Reprod 56:194&amp;lt;/ref&amp;gt;. While these studies indicate that similar biochemical and clinical manifestations in humans originate from excess androgen exposure of the female fetus, it must be noted that it is very unlikely for any excess androgen production to be passed across the placenta from the mother to her daughter. This is because mechanisms such as androgen binding proteins and placental metabolism of androgen prevent excess androgen entering the circulation of the fetus &amp;lt;ref name=h2&amp;gt;&amp;lt;pubmed&amp;gt;12098657&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
====Cell Culture Models====&lt;br /&gt;
&lt;br /&gt;
While studies have shown that the adrenal could be a source of excess androgen such as the adrenal &amp;lt;ref name=h3&amp;gt;&amp;lt;pubmed&amp;gt;7962325&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;, they were followed by various studies using cell culture models which demonstrated that the ovary was the major source of excess androgen &amp;lt;ref name=h4/&amp;gt; &amp;lt;ref name=h5&amp;gt;&amp;lt;pubmed&amp;gt;9302378&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. ''In vitro'' studies have shown that the production of steroids is abnormal in theca cells &amp;lt;ref name=h3/&amp;gt;. In women affected by PCOS, stimulation by human chorionic gonadotrophin (hCG) is followed by an increase in thecal steroid production after suppression of LH by a GnRH analogue &amp;lt;ref name=h5/&amp;gt;. Theca cells cultured from polycystic ovaries produce 20 times as much androstenedione as those from normal ovaries &amp;lt;ref name=h4/&amp;gt; with increased expression of mRNA for enzymes responsible for making steroids also reported in following studies. &amp;lt;ref name=h6&amp;gt;&amp;lt;pubmed&amp;gt;10852468&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; These results have prompted many studies on genes encoding these steroidogeneic enzymes.&lt;br /&gt;
&lt;br /&gt;

===&amp;lt;u&amp;gt;The Genetics of Infertility: Current Status of the Field&amp;lt;/u&amp;gt;===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3885174&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article attempted to determine the role that genetics plays in female infertility. It was noted that several prominent causes of female infertility such as Galactosemia and Primary Ovarian Failure (POF) were associated with specific genes, with the GALT gene contributing to the former condition and the FMR1 gene contributing to the latter.&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Causes of Sterility in Bosnia-Herzegovina Population&amp;lt;/u&amp;gt;===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC4499307&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
The study conducted as laid out in this article examined the causes of female sterility in the Bosnia-Herzegovina population. Married participants were arranged into various groups based upon their age. The experiment came to the conclusion that in approximately 42% of infertile married couples, female sterility was the primary cause. The two primary causes of female infertility were tubal deficiencies (31% of cases) and Diminished Ovarian Reserves (38% of cases)&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Epidemiology, diagnosis, and management of polycystic ovary syndrome&amp;lt;/u&amp;gt;===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This research article examines the causes of polycystic ovary syndrome (POS), a common cause of infertility in women. The article concluded that 50-70% of women suffer from insulin resistance secondary to Type 2 Diabetes and in many cases obseity, which may contribute partially to POS. Furthermore, 85-90% of women with oligomenorrhea also had POS, suggesting that it is an underlying cause. However, the exact pathophysiology of POS was not determined.&lt;br /&gt;
&lt;br /&gt;
=Signs and Symptoms=&lt;br /&gt;
&lt;br /&gt;
The symptoms of PCOS are different for each women. The three cardinal signs of PCOS are hyperandrogenism, polycystic ovaries and ovarian dysfunction &amp;lt;ref name=sign1&amp;gt;&amp;lt;pubmed&amp;gt;14688154&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Common clinical symptoms include &amp;lt;ref&amp;gt; Women's Heath, U.S. Department of Health and Human Services ,[ http://www.womenshealth.gov/publications/our-publications/fact-sheet/polycystic-ovary-syndrome.html#d ], 'Polycystic ovary syndrome (PCOS) fact sheet'&amp;lt;/ref&amp;gt; ;&lt;br /&gt;
&lt;br /&gt;
* Infertility- due to anovulation caused by PCOS. &lt;br /&gt;
* Irregular Menstrual Cycles&lt;br /&gt;
* Hirsutism&lt;br /&gt;
* Ovarian Cysts&lt;br /&gt;
* Obesity&lt;br /&gt;
* Male Pattern Baldness&lt;br /&gt;
* Skin Tags&lt;br /&gt;
* Pelvic Pain&lt;br /&gt;
&lt;br /&gt;
Along with obesity, PCOS is also associated with other metabolic issues such as insulin resistance, hyperinsulinemia and type 2 diabetes mellitus. It has also been associated with cardiovascular problems and cancers of the breast and endometrium &amp;lt;ref name=sign3&amp;gt;&amp;lt;pubmed&amp;gt;PMC4341818&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=Diagnosis=&lt;br /&gt;
&lt;br /&gt;
A major diagnostic tool for PCOS is a pelvic ultrasound, but PCOS diagnosis cannot be completely dependent on just pelvic ultrasounds. A patient with PCOS may not necessarily have polycystic ovaries, and those with ovarian cysts may not necessarily have PCOS. A range of diagnostic assessments and associated symptoms have to be thoroughly investigated.&lt;br /&gt;
&lt;br /&gt;
===Medical history and examination===&lt;br /&gt;
Clinical questions are asked or filled out in the form of a questionnaire to assess and assist in the diagnosis of PCOS. Studies show that those with a history:&lt;br /&gt;
*infrequent and irregular menstruation&lt;br /&gt;
*hirsutism (related to high levels of androgens in the blood – hyperandrogenism)&lt;br /&gt;
*obesity&lt;br /&gt;
*acne production &lt;br /&gt;
are at a higher predictive risk of PCOS. But questions regarding failed pregnancy attempts and history of nipple discharge proved no correlation in diagnosing PCOS. &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/17872783 &amp;lt;pubmed&amp;gt; 17872783 &amp;lt;/pubmed&amp;gt; &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Blood Test===&lt;br /&gt;
A patient with elevated levels of androgens, a medical condition called &amp;lt;b&amp;gt;hyperandrogenism &amp;lt;/b&amp;gt;, is very highly likely to have PCOS. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/20591140 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&amp;lt;b&amp;gt; Androgens &amp;lt;/b&amp;gt; , such as testosterone, and &amp;lt;b&amp;gt;free androgen index (FAI) &amp;lt;/b&amp;gt; are the two tests best used in diagnosing hyperandrogenism.&lt;br /&gt;
Androgen excess in PCOS is a result from increased synthesis and release of ovarian androgens. &amp;lt;b&amp;gt;Dehydroepiandrosterone sulfate &amp;lt;/b&amp;gt; (DHEA-S) levels are used as a biomarker for testing androgen levels, as it is made exclusively by the adrenal glands. DHEA-S levels of above 1890 micromol/L is extremely suggestive of hyperandrogenism. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/18844715 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&amp;lt;b&amp;gt;Free androgen index (FAI) &amp;lt;/b&amp;gt; is the ratio of total testosterone measurement to levels of &amp;lt;b&amp;gt; sex hormone-binding globulin &amp;lt;/b&amp;gt; (SHBG). Those with PCOS will have high FAI, as this indicates a high ration of free testosterone in the body.&lt;br /&gt;
Other blood tests are also done to help exclude other predisposing factors such as levels of &amp;lt;b&amp;gt; Thyroid Stimulating Hormone &amp;lt;/b&amp;gt; (LSH) and &amp;lt;b&amp;gt; Follicle-stimulating hormone &amp;lt;/b&amp;gt; (FSH). An elevated ratio of LSH to FSH, of above 2:1 &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/14737959 &amp;lt;/ref&amp;gt;, indicates a possibility, but not definitively, of PCOS.&lt;br /&gt;
The effect of &amp;lt;b&amp;gt; insulin &amp;lt;/b&amp;gt; on blood can also be tested for insulin resistance. Insulin resistance enhances androgen production and increases free androgen levels by reducing SHBG. This can used as an indication marker for the possibility of PCOS&lt;br /&gt;
A study in 2014 showed that &amp;lt;b&amp;gt; Anti-Müllerian hormone &amp;lt;/b&amp;gt; (AMH) is found to be elevated in patients with PCOS &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24821925 &amp;lt;/ref&amp;gt;, giving rise to its potential clinical implication in diagnosing PCOS. AMH is exclusively produced in ovarian follicles, with individual AMH concentration reflecting the quantity of remaining primordial follicles and measure of ovarian reserve. &lt;br /&gt;
&lt;br /&gt;
===Gynecologic ultrasonography===&lt;br /&gt;
Gynecologic ultrasonography is a pelvic ultrasound, specifically to the female pelvic region, with regards to the uterus, ovaries and the fallopian tube. The examination can be performed by transabdominal ultrasonography, with a full bladder, or transvaginal ultrasonography with a vaginal transducer. Typically transvaginal imaging shows a better and clearer image than transabdominal ultrasonography, as it uses higher frequency imaging, but is limited to areas it can reach. In the case of PCOS, both techniques can provide an image of the ovaries. Studies suggest that if more than 25 follicles are seen in an ovary, predominantly in the periphery, in women between 18-35 years, it is described to have a polycystic ovarian morphology. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24345633 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Magnetic Resonance Imaging===&lt;br /&gt;
Ovaries can also be seen on MRIs. On MRIs, PCOS is characterized by numberous peripheral cysts where the ovaries affected to be slightly larger than normal. Although MRI is seen to be effective in ovarian imaging, the finding of peripheral ovarian cysts in MRIsmay not be PCOS specific. &amp;lt;ref&amp;gt;  http://www.ncbi.nlm.nih.gov/pubmed/8888256 &amp;lt;/ref&amp;gt; But studies have seen that MR imaging in adolescence uncover distinct differences between young patients with and without PCOS &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/23292744 &amp;lt;/ref&amp;gt;, with also great diagnostic sensitivity with patients between the age of 21-30 &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/19241321 &amp;lt;/ref&amp;gt;, providing assistance of imagery in patients whom may be opposed to transvaginal ultrasounds.&lt;br /&gt;
&lt;br /&gt;
=Prevention=&lt;br /&gt;
&lt;br /&gt;
==Impact of physical activity on ovarian reserve markers in normal, overweight and obese reproductive age women==&lt;br /&gt;
&amp;lt;pubmed&amp;gt;25509968&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study focuses on the effect of physical activity on fertility in three groups of women at reproductive age; normal, overweight and obese. The results from the study suggest that there was a marked improvement in fertility as shown by the ovarian reserve markers for all 3 groups, however it was most significant in the overweight and obese groups. This study is relevant to our project as it gives an insight into the preventative measures that can be taken for infertility. &lt;br /&gt;
&lt;br /&gt;
==Risk factors of polycystic ovarian syndrome among Li People==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;26276294&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study examined the risk factors entailed in Polycystic Ovarian Syndrdome (PCOS) amoung Li people. Using the method of a case control study, questionnaires were given to female Li people with and without PCOS. Analysis of the questionnaires showed that family history of diabetes, family history of infertility, bad mood, lack of physical exercise are all high risk factors of PCOS. As a result, management of these risk factors can be taken into consideration when preventing infertility through PCOS.&lt;br /&gt;
&lt;br /&gt;
==Vitamin D and female fertility==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;24717915&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article is a review focusing on research regarding Vitamin D and fertility over the past year. The review found that the levels of Vitamin D is crucial for women undergoing in-vitro fertilisation. It  was also found that Vitamin D was beneficial for women with PCOS and carried a protective effect against endometriosis. These observations suggest that having sufficient Vitamin D in your body can be preventative for problems associated with fertility.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Treatment=&lt;br /&gt;
There currently is no cure for PCOS. Treatment maybe involve lifestyle changes or hormonal augmentation in regulating periods, hirsutism, and acne, in addition to regulating androgen levels.&lt;br /&gt;

| General Practitioners tend to prescribe oral anti-oestrogens, most commonly the contraceptive pill, to restore ovulation.&lt;br /&gt;
| This method only has a 50% success rate in PCOS patients. It does not directly increase fertility rates, but restores the menstrual cycle.&lt;br /&gt;
 &lt;br /&gt;
|-bgcolor=&amp;quot;FAF5FF&amp;quot;&lt;br /&gt;
| Lifestyle changes are highly encouraged by medical practitioners. Diet and exercise regimes can be designed with a dietitian or nutritionist. &lt;br /&gt;
| Exercise and diet plans do not directly increase fertility. They are designed to enhance weight loss, which in some patients can encourage normal hormone levels from the pituitary and thyroid. &lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| Clomiphene citrate administration (generally in pill form, as prescribed by a GP). Such pills stimulate the pituitary gland to release GnRH to simulate ovulation (with a 72% success rate in the ___ trial). &lt;br /&gt;
| Clomiphene can cause multiple side effects, most notably abnormal uterine bleeding and pelvic pain to due enlargement of the ovaries. &lt;br /&gt;
&lt;br /&gt;
Thus, it cannot be as frequently prescribed as the contraceptive pill, and careful patient monitoring is imperative. &lt;br /&gt;
&lt;br /&gt;
|-bgcolor=&amp;quot;FAF5FF&amp;quot;&lt;br /&gt;
| Higher fertility rates are observed in treatments combining clomiphene citrate and metformin (79% success).&lt;br /&gt;
| Similar disadvantages as clomiphene, above.&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
===New Trials===&lt;br /&gt;
&lt;br /&gt;
Some studies have found that regular Selenium supplements can encourage fertility among PCOS patients. The program, which is still in its early trial period, requires women to consume selenium tablets for 8 weeks. This study has found a significant decrease in dehydroepiandrosterone (DHEA) levels in patients, thus reducing excessive hair growth associated with PCOS. A direct link to increased fertility is yet to be established, and thus further testing is required.&lt;br /&gt;

=Female Infertility=&lt;br /&gt;
&lt;br /&gt;
[[File:Prevalence of Primary Infertility in 2010.jpeg|400px|thumb|right|Prevalence of Primary Infertility in 2010]]&lt;br /&gt;
&lt;br /&gt;
Female Infertility refers to the failure to conceive after one year of regular unprotected intercourse in females &amp;lt;ref name=one&amp;gt;&amp;lt;pubmed&amp;gt;26150870&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. In 2010, infertility affected 48.5 million couples world wide and the areas of highest prevalence included North Africa and Middle East, South Asia, Central/Eastern Europe and Central Asia and Sub-Saharan Africa &amp;lt;ref name=two&amp;gt;&amp;lt;pubmed&amp;gt;23271957&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. As there are several causes of female infertility, we will be focusing on infertility that is caused by '''Polycystic Ovarian Syndrome''' (PCOS), the most common cause of infertility that is medically treatable &amp;lt;ref name=one/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Polycystic Ovarian Syndrome==&lt;br /&gt;
Polycystic Ovarian Syndrome (PCOS) is a common endocrine disorder, affecting up to 20% of reproductive aged women [3] It is the most common cause of anovulatory infertility [1] which refers to infertility caused by the the absence of ovulation.&lt;br /&gt;
&lt;br /&gt;
=Causes=&lt;br /&gt;
&lt;br /&gt;
PCOS is a disorder of heterogeneous origin with unknown aetiology &amp;lt;ref name=four&amp;gt;&amp;lt;pubmed&amp;gt;21896560&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Studies have shown that both genetic and environmental factors contribute to the development of PCOS in women however there is limited research into the actual interactions between these two factors &amp;lt;ref name=un&amp;gt;&amp;lt;pubmed&amp;gt;17185788&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Genetic Factors===&lt;br /&gt;
&lt;br /&gt;
Despite the lack of information regarding its aetiology, there is increasing evidence for a genetic involvement in the endocrine disorder. Studies have shown that genes play an important role in contributing towards the clinical and biochemical features of the disease &amp;lt;ref name=four/&amp;gt;. This evidence includes the family clustering of cases, greater unanimity between monozygotic twins than heterozygotic twins and the ability to inherit endocrine and  metabolic features of PCOS &amp;lt;ref name=four/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
In one study, 115 sisters of women with PCOS were examined and results showed that half of these sisters had high testosterone levels, suggesting that hyperandrogenemia is a common trait with a dominant pattern of inheritance. These results strongly supported the idea of the familial clustering of biochemical features such as hyperandrogenism in first degree relatives &amp;lt;ref name=deux&amp;gt;&amp;lt;pubmed&amp;gt;9843997&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
Several genes have been considered to play an important role in the development of PCOS such as CYP11A, the insulin gene, the follistatin gene and a region near the insulin receptor gene. Yet, the evidence supporting most of these genes has been refuted by larger studies, except for the region near the insulin receptor gene &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
There has been strong evidence linking the gene CYP11a with hyperandrogenism in women with PCOS. &amp;lt;ref name=cinq&amp;gt;&amp;lt;pubmed&amp;gt;9147642&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; While it doesn't isolate this gene as the sole cause of PCOS, variation of the genotype at this locus contributes to production of excess androgen &amp;lt;ref name=h4&amp;gt;&amp;lt;pubmed&amp;gt;7962289&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Studies have also shown that there is strong evidence for linkage between the alleles at the Variable Number Tandem Repeats (VNTR) which is situated 5' to the insulin gene and PCOS. The data from the study suggests that it is a very susceptible region in PCOS and also may play a role in the development of hyperinsulinaemia &amp;lt;ref name=trois&amp;gt;&amp;lt;pubmed&amp;gt;9455828&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
===Environmental Factors===&lt;br /&gt;
The prevalence of PCOS in populations where there has been a constant gene pool indicates that environmental factors play a significant role in the aetiology of PCOS.&lt;br /&gt;
&lt;br /&gt;
===Obesity and Diet===&lt;br /&gt;
Obesity is the major environmental factor driving the development of PCOS in susceptible individuals. The rising rates of PCOS have been paralleled by the widespread emergence of obesity and type 2 diabetes which are prevalent in developed countries. The risk of developing PCOS from obesity is compounded by  poor dietary choices and lack of physical activity which has begun to characterise the lifestyle in developed countries &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Medication===&lt;br /&gt;
Studies have shown that valproic acid in medication used to treat epilepsy and bipolar disorders contributes to the development of PCOS. Women with these disorders  may develop the typical features of PCOS such as polycystic ovaries, anovulation, hyperandrogenism and obesity &amp;lt;ref name=quartre&amp;gt;&amp;lt;pubmed&amp;gt;8413434&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Recent studies also suggest that the weight gain from medication is significant as it can lead to the development of PCOS &amp;lt;ref name=deux/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=Pathogenesis=&lt;br /&gt;
&lt;br /&gt;
The pathogenesis of polycystic ovarian syndrome is poorly understood, however it is believed that insulin resistance and excess androgens such as testosterone play a fundamental role.&lt;br /&gt;
Underlying factors such as obesity and genetic predispositions likely contribute to the onset of polycystic ovarian syndrome through the development of a combination of hyperinsulinemia and hyperandrogenemia.&amp;lt;ref name=eleven&amp;gt;&amp;lt;pubmed&amp;gt;PMC4556908&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Hyperinsulinemia&amp;lt;/u&amp;gt;===&lt;br /&gt;
&lt;br /&gt;
Hyperinsulinemia is a term that defines the presence of excessive amounts of insulin in the blood relative to the amount of glucose. &amp;lt;ref name=fourteen&amp;gt;&amp;lt;pubmed&amp;gt;PMC4114053&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; This phenomenon is typically associated with obesity and excess adipose tissue, both of which are associated with insulin resistance. In order to overcome this resistance, insulin secretion is increased in an attempt to normalise blood glucose levels, thereby leading to hyperinsulineamia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC2782313&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; Excessive levels of insulin typically cause disruption to the hypothalamus-hypophysis-ovary axis whilst insulin resistance in ovarian tissues leads to decreased metabolic signalling. However, steroidogenic activity is largely unaffected by the impaired metabolic signalling, thereby paving the way androgens to become more effect and paving the way towards hyperandrogenemia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
[[File:Patholophysiology of Polycystic Ovarian Syndrome.jpg|500px|thumb|left|The impact of hyperinsulinemia and hyperandrogenemia on the development of polycystic ovarian syndrome]]&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Hyperandrogenemia&amp;lt;/u&amp;gt;===&lt;br /&gt;
&lt;br /&gt;
Hyperandrogenemia is a hallmark of the development of polycystic ovarian syndrome, with 80% of women presenting with excess androgen also having polycystic ovaries.&amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; The disruption of the hypothalamus hypophysis ovary axis as a result of hyperinsulinemia increases the release of GnRH and LH, leading to increased androgen production in the ovarian theca cells. Hyperandrogenemia decreases the feedback sensitivity of both estradiol and progesterone within gonadotropic hypothalmic cells. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; A deficiency of FSH is observed and correlates with the increased secretion of GnRH and LH. As a result of this deficiency, graunlosa  cell aromatisation to oestrogens as well as follicle maturation and ovulation will be drastically impaired.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3453528&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
As a consequence of the impairment of follicle maturation, small antral follicles will accumulate within the periphery of the ovary and develop a cystic morphology. Ovulation will be unable to occur due to the absence of mature follicles, culminating in infertility.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4562327&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Hyperandrogenism&amp;lt;/u&amp;gt;===&lt;br /&gt;
&lt;br /&gt;
====Animal Models====&lt;br /&gt;
&lt;br /&gt;
Studies conducted on female rhesus monkeys have supported evidence for the foetal origins of the clinical features of PCOS &amp;lt;ref name=h1&amp;gt;&amp;lt;pubmed&amp;gt;18406243&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.  It has been shown that in human females, an excess of androgen exposure at any stage from the development of the ovaries to the onset of puberty manifests as characteristic features of PCOS, such as resistance to insulin and Luteinising Hormone (LH) hypersecretion. After exposure to levels of testosterone matching those of fetal males, in utero, female rhesus monkeys were found to display the clinical and biochemical features typical of PCOS such as hypersecretion of LH and abnormal insulin action. These results correlated to those of similar studies conducted on sheep, where the pregnant ewe was exposed to excessive levels of testosterone and LH secretion and abnormality in ovarian cycles were again prominent features &amp;lt;ref name=sheep&amp;gt;Padmanabhan V, Evans NP, Taylor JA, Robinson JE1997 '''Prenatal exposure to  androgens  leads  to  the  development  of  cystic  ovaries  in  the  sheep'''. Biol Reprod 56:194&amp;lt;/ref&amp;gt;. While these studies indicate that similar biochemical and clinical manifestations in humans originate from excess androgen exposure of the female fetus, it must be noted that it is very unlikely for any excess androgen production to be passed across the placenta from the mother to her daughter. This is because mechanisms such as androgen binding proteins and placental metabolism of androgen prevent excess androgen entering the circulation of the fetus &amp;lt;ref name=h2&amp;gt;&amp;lt;pubmed&amp;gt;12098657&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
====Cell Culture Models====&lt;br /&gt;
&lt;br /&gt;
While studies have shown that the adrenal could be a source of excess androgen such as the adrenal &amp;lt;ref name=h3&amp;gt;&amp;lt;pubmed&amp;gt;7962325&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;, they were followed by various studies using cell culture models which demonstrated that the ovary was the major source of excess androgen &amp;lt;ref name=h4/&amp;gt; &amp;lt;ref name=h5&amp;gt;&amp;lt;pubmed&amp;gt;9302378&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. ''In vitro'' studies have shown that the production of steroids is abnormal in theca cells &amp;lt;ref name=h3/&amp;gt;. In women affected by PCOS, stimulation by human chorionic gonadotrophin (hCG) is followed by an increase in thecal steroid production after suppression of LH by a GnRH analogue &amp;lt;ref name=h5/&amp;gt;. Theca cells cultured from polycystic ovaries produce 20 times as much androstenedione as those from normal ovaries &amp;lt;ref name=h4/&amp;gt; with increased expression of mRNA for enzymes responsible for making steroids also reported in following studies. &amp;lt;ref name=h6&amp;gt;&amp;lt;pubmed&amp;gt;10852468&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; These results have prompted many studies on genes encoding these steroidogeneic enzymes.&lt;br /&gt;
&lt;br /&gt;

===&amp;lt;u&amp;gt;The Genetics of Infertility: Current Status of the Field&amp;lt;/u&amp;gt;===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3885174&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article attempted to determine the role that genetics plays in female infertility. It was noted that several prominent causes of female infertility such as Galactosemia and Primary Ovarian Failure (POF) were associated with specific genes, with the GALT gene contributing to the former condition and the FMR1 gene contributing to the latter.&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Causes of Sterility in Bosnia-Herzegovina Population&amp;lt;/u&amp;gt;===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC4499307&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
The study conducted as laid out in this article examined the causes of female sterility in the Bosnia-Herzegovina population. Married participants were arranged into various groups based upon their age. The experiment came to the conclusion that in approximately 42% of infertile married couples, female sterility was the primary cause. The two primary causes of female infertility were tubal deficiencies (31% of cases) and Diminished Ovarian Reserves (38% of cases)&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Epidemiology, diagnosis, and management of polycystic ovary syndrome&amp;lt;/u&amp;gt;===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This research article examines the causes of polycystic ovary syndrome (POS), a common cause of infertility in women. The article concluded that 50-70% of women suffer from insulin resistance secondary to Type 2 Diabetes and in many cases obseity, which may contribute partially to POS. Furthermore, 85-90% of women with oligomenorrhea also had POS, suggesting that it is an underlying cause. However, the exact pathophysiology of POS was not determined.&lt;br /&gt;
&lt;br /&gt;
=Signs and Symptoms=&lt;br /&gt;
&lt;br /&gt;
The symptoms of PCOS are different for each women. The three cardinal signs of PCOS are hyperandrogenism, polycystic ovaries and ovarian dysfunction &amp;lt;ref name=sign1&amp;gt;&amp;lt;pubmed&amp;gt;14688154&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Common clinical symptoms include &amp;lt;ref&amp;gt; Women's Heath, U.S. Department of Health and Human Services ,[ http://www.womenshealth.gov/publications/our-publications/fact-sheet/polycystic-ovary-syndrome.html#d ], 'Polycystic ovary syndrome (PCOS) fact sheet'&amp;lt;/ref&amp;gt; ;&lt;br /&gt;
&lt;br /&gt;
* Infertility- due to anovulation caused by PCOS. &lt;br /&gt;
* Irregular Menstrual Cycles&lt;br /&gt;
* Hirsutism&lt;br /&gt;
* Ovarian Cysts&lt;br /&gt;
* Obesity&lt;br /&gt;
* Male Pattern Baldness&lt;br /&gt;
* Skin Tags&lt;br /&gt;
* Pelvic Pain&lt;br /&gt;
&lt;br /&gt;
Along with obesity, PCOS is also associated with other metabolic issues such as insulin resistance, hyperinsulinemia and type 2 diabetes mellitus. It has also been associated with cardiovascular problems and cancers of the breast and endometrium &amp;lt;ref name=sign3&amp;gt;&amp;lt;pubmed&amp;gt;PMC4341818&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=Diagnosis=&lt;br /&gt;
&lt;br /&gt;
A major diagnostic tool for PCOS is a pelvic ultrasound, but PCOS diagnosis cannot be completely dependent on just pelvic ultrasounds. A patient with PCOS may not necessarily have polycystic ovaries, and those with ovarian cysts may not necessarily have PCOS. A range of diagnostic assessments and associated symptoms have to be thoroughly investigated.&lt;br /&gt;
&lt;br /&gt;
===Medical history and examination===&lt;br /&gt;
Clinical questions are asked or filled out in the form of a questionnaire to assess and assist in the diagnosis of PCOS. Studies show that those with a history:&lt;br /&gt;
*infrequent and irregular menstruation&lt;br /&gt;
*hirsutism (related to high levels of androgens in the blood – hyperandrogenism)&lt;br /&gt;
*obesity&lt;br /&gt;
*acne production &lt;br /&gt;
are at a higher predictive risk of PCOS. But questions regarding failed pregnancy attempts and history of nipple discharge proved no correlation in diagnosing PCOS. &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/17872783 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Blood Test===&lt;br /&gt;
A patient with elevated levels of androgens, a medical condition called &amp;lt;b&amp;gt;hyperandrogenism &amp;lt;/b&amp;gt;, is very highly likely to have PCOS. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/20591140 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&amp;lt;b&amp;gt; Androgens &amp;lt;/b&amp;gt; , such as testosterone, and &amp;lt;b&amp;gt;free androgen index (FAI) &amp;lt;/b&amp;gt; are the two tests best used in diagnosing hyperandrogenism.&lt;br /&gt;
Androgen excess in PCOS is a result from increased synthesis and release of ovarian androgens. &amp;lt;b&amp;gt;Dehydroepiandrosterone sulfate &amp;lt;/b&amp;gt; (DHEA-S) levels are used as a biomarker for testing androgen levels, as it is made exclusively by the adrenal glands. DHEA-S levels of above 1890 micromol/L is extremely suggestive of hyperandrogenism. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/18844715 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&amp;lt;b&amp;gt;Free androgen index (FAI) &amp;lt;/b&amp;gt; is the ratio of total testosterone measurement to levels of &amp;lt;b&amp;gt; sex hormone-binding globulin &amp;lt;/b&amp;gt; (SHBG). Those with PCOS will have high FAI, as this indicates a high ration of free testosterone in the body.&lt;br /&gt;
Other blood tests are also done to help exclude other predisposing factors such as levels of &amp;lt;b&amp;gt; Thyroid Stimulating Hormone &amp;lt;/b&amp;gt; (LSH) and &amp;lt;b&amp;gt; Follicle-stimulating hormone &amp;lt;/b&amp;gt; (FSH). An elevated ratio of LSH to FSH, of above 2:1 &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/14737959 &amp;lt;/ref&amp;gt;, indicates a possibility, but not definitively, of PCOS.&lt;br /&gt;
The effect of &amp;lt;b&amp;gt; insulin &amp;lt;/b&amp;gt; on blood can also be tested for insulin resistance. Insulin resistance enhances androgen production and increases free androgen levels by reducing SHBG. This can used as an indication marker for the possibility of PCOS&lt;br /&gt;
A study in 2014 showed that &amp;lt;b&amp;gt; Anti-Müllerian hormone &amp;lt;/b&amp;gt; (AMH) is found to be elevated in patients with PCOS &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24821925 &amp;lt;/ref&amp;gt;, giving rise to its potential clinical implication in diagnosing PCOS. AMH is exclusively produced in ovarian follicles, with individual AMH concentration reflecting the quantity of remaining primordial follicles and measure of ovarian reserve. &lt;br /&gt;
&lt;br /&gt;
===Gynecologic ultrasonography===&lt;br /&gt;
Gynecologic ultrasonography is a pelvic ultrasound, specifically to the female pelvic region, with regards to the uterus, ovaries and the fallopian tube. The examination can be performed by transabdominal ultrasonography, with a full bladder, or transvaginal ultrasonography with a vaginal transducer. Typically transvaginal imaging shows a better and clearer image than transabdominal ultrasonography, as it uses higher frequency imaging, but is limited to areas it can reach. In the case of PCOS, both techniques can provide an image of the ovaries. Studies suggest that if more than 25 follicles are seen in an ovary, predominantly in the periphery, in women between 18-35 years, it is described to have a polycystic ovarian morphology. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24345633 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Magnetic Resonance Imaging===&lt;br /&gt;
Ovaries can also be seen on MRIs. On MRIs, PCOS is characterized by numberous peripheral cysts where the ovaries affected to be slightly larger than normal. Although MRI is seen to be effective in ovarian imaging, the finding of peripheral ovarian cysts in MRIsmay not be PCOS specific. &amp;lt;ref&amp;gt;  http://www.ncbi.nlm.nih.gov/pubmed/8888256 &amp;lt;/ref&amp;gt; But studies have seen that MR imaging in adolescence uncover distinct differences between young patients with and without PCOS &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/23292744 &amp;lt;/ref&amp;gt;, with also great diagnostic sensitivity with patients between the age of 21-30 &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/19241321 &amp;lt;/ref&amp;gt;, providing assistance of imagery in patients whom may be opposed to transvaginal ultrasounds.&lt;br /&gt;
&lt;br /&gt;
=Prevention=&lt;br /&gt;
&lt;br /&gt;
==Impact of physical activity on ovarian reserve markers in normal, overweight and obese reproductive age women==&lt;br /&gt;
&amp;lt;pubmed&amp;gt;25509968&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study focuses on the effect of physical activity on fertility in three groups of women at reproductive age; normal, overweight and obese. The results from the study suggest that there was a marked improvement in fertility as shown by the ovarian reserve markers for all 3 groups, however it was most significant in the overweight and obese groups. This study is relevant to our project as it gives an insight into the preventative measures that can be taken for infertility. &lt;br /&gt;
&lt;br /&gt;
==Risk factors of polycystic ovarian syndrome among Li People==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;26276294&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study examined the risk factors entailed in Polycystic Ovarian Syndrdome (PCOS) amoung Li people. Using the method of a case control study, questionnaires were given to female Li people with and without PCOS. Analysis of the questionnaires showed that family history of diabetes, family history of infertility, bad mood, lack of physical exercise are all high risk factors of PCOS. As a result, management of these risk factors can be taken into consideration when preventing infertility through PCOS.&lt;br /&gt;
&lt;br /&gt;
==Vitamin D and female fertility==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;24717915&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article is a review focusing on research regarding Vitamin D and fertility over the past year. The review found that the levels of Vitamin D is crucial for women undergoing in-vitro fertilisation. It  was also found that Vitamin D was beneficial for women with PCOS and carried a protective effect against endometriosis. These observations suggest that having sufficient Vitamin D in your body can be preventative for problems associated with fertility.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Treatment=&lt;br /&gt;
There currently is no cure for PCOS. Treatment maybe involve lifestyle changes or hormonal augmentation in regulating periods, hirsutism, and acne, in addition to regulating androgen levels.&lt;br /&gt;

| '''DISADVANTAGES'''&lt;br /&gt;
|-&lt;br /&gt;
| General Practitioners tend to prescribe oral anti-oestrogens, most commonly the contraceptive pill, to restore ovulation.&lt;br /&gt;
| This method only has a 50% success rate in PCOS patients. It does not directly increase fertility rates, but restores the menstrual cycle.&lt;br /&gt;
 &lt;br /&gt;
|-bgcolor=&amp;quot;FAF5FF&amp;quot;&lt;br /&gt;
| Lifestyle changes are highly encouraged by medical practitioners. Diet and exercise regimes can be designed with a dietitian or nutritionist. &lt;br /&gt;
| Exercise and diet plans do not directly increase fertility. They are designed to enhance weight loss, which in some patients can encourage normal hormone levels from the pituitary and thyroid. &lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| Clomiphene citrate administration (generally in pill form, as prescribed by a GP). Such pills stimulate the pituitary gland to release GnRH to simulate ovulation (with a 72% success rate in the ___ trial). &lt;br /&gt;
| Clomiphene can cause multiple side effects, most notably abnormal uterine bleeding and pelvic pain to due enlargement of the ovaries. &lt;br /&gt;
&lt;br /&gt;
Thus, it cannot be as frequently prescribed as the contraceptive pill, and careful patient monitoring is imperative. &lt;br /&gt;
&lt;br /&gt;
|-bgcolor=&amp;quot;FAF5FF&amp;quot;&lt;br /&gt;
| Higher fertility rates are observed in treatments combining clomiphene citrate and metformin (79% success).&lt;br /&gt;
| Similar disadvantages as clomiphene, above.&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
===New Trials===&lt;br /&gt;
&lt;br /&gt;
Some studies have found that regular Selenium supplements can encourage fertility among PCOS patients. The program, which is still in its early trial period, requires women to consume selenium tablets for 8 weeks. This study has found a significant decrease in dehydroepiandrosterone (DHEA) levels in patients, thus reducing excessive hair growth associated with PCOS. A direct link to increased fertility is yet to be established, and thus further testing is required.&lt;br /&gt;

=Female Infertility=&lt;br /&gt;
&lt;br /&gt;
[[File:Prevalence of Primary Infertility in 2010.jpeg|400px|thumb|right|Prevalence of Primary Infertility in 2010]]&lt;br /&gt;
&lt;br /&gt;
Female Infertility refers to the failure to conceive after one year of regular unprotected intercourse in females &amp;lt;ref name=one&amp;gt;&amp;lt;pubmed&amp;gt;26150870&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. In 2010, infertility affected 48.5 million couples world wide and the areas of highest prevalence included North Africa and Middle East, South Asia, Central/Eastern Europe and Central Asia and Sub-Saharan Africa &amp;lt;ref name=two&amp;gt;&amp;lt;pubmed&amp;gt;23271957&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. As there are several causes of female infertility, we will be focusing on infertility that is caused by '''Polycystic Ovarian Syndrome''' (PCOS), the most common cause of infertility that is medically treatable &amp;lt;ref name=one/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Polycystic Ovarian Syndrome==&lt;br /&gt;
Polycystic Ovarian Syndrome (PCOS) is a common endocrine disorder, affecting up to 20% of reproductive aged women [3] It is the most common cause of anovulatory infertility [1] which refers to infertility caused by the the absence of ovulation.&lt;br /&gt;
&lt;br /&gt;
=Causes=&lt;br /&gt;
&lt;br /&gt;
PCOS is a disorder of heterogeneous origin with unknown aetiology &amp;lt;ref name=four&amp;gt;&amp;lt;pubmed&amp;gt;21896560&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Studies have shown that both genetic and environmental factors contribute to the development of PCOS in women however there is limited research into the actual interactions between these two factors &amp;lt;ref name=un&amp;gt;&amp;lt;pubmed&amp;gt;17185788&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Genetic Factors===&lt;br /&gt;
&lt;br /&gt;
Despite the lack of information regarding its aetiology, there is increasing evidence for a genetic involvement in the endocrine disorder. Studies have shown that genes play an important role in contributing towards the clinical and biochemical features of the disease &amp;lt;ref name=four/&amp;gt;. This evidence includes the family clustering of cases, greater unanimity between monozygotic twins than heterozygotic twins and the ability to inherit endocrine and  metabolic features of PCOS &amp;lt;ref name=four/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
In one study, 115 sisters of women with PCOS were examined and results showed that half of these sisters had high testosterone levels, suggesting that hyperandrogenemia is a common trait with a dominant pattern of inheritance. These results strongly supported the idea of the familial clustering of biochemical features such as hyperandrogenism in first degree relatives &amp;lt;ref name=deux&amp;gt;&amp;lt;pubmed&amp;gt;9843997&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
Several genes have been considered to play an important role in the development of PCOS such as CYP11A, the insulin gene, the follistatin gene and a region near the insulin receptor gene. Yet, the evidence supporting most of these genes has been refuted by larger studies, except for the region near the insulin receptor gene &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
There has been strong evidence linking the gene CYP11a with hyperandrogenism in women with PCOS. &amp;lt;ref name=cinq&amp;gt;&amp;lt;pubmed&amp;gt;9147642&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; While it doesn't isolate this gene as the sole cause of PCOS, variation of the genotype at this locus contributes to production of excess androgen &amp;lt;ref name=h4&amp;gt;&amp;lt;pubmed&amp;gt;7962289&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Studies have also shown that there is strong evidence for linkage between the alleles at the Variable Number Tandem Repeats (VNTR) which is situated 5' to the insulin gene and PCOS. The data from the study suggests that it is a very susceptible region in PCOS and also may play a role in the development of hyperinsulinaemia &amp;lt;ref name=trois&amp;gt;&amp;lt;pubmed&amp;gt;9455828&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
===Environmental Factors===&lt;br /&gt;
The prevalence of PCOS in populations where there has been a constant gene pool indicates that environmental factors play a significant role in the aetiology of PCOS.&lt;br /&gt;
&lt;br /&gt;
===Obesity and Diet===&lt;br /&gt;
Obesity is the major environmental factor driving the development of PCOS in susceptible individuals. The rising rates of PCOS have been paralleled by the widespread emergence of obesity and type 2 diabetes which are prevalent in developed countries. The risk of developing PCOS from obesity is compounded by  poor dietary choices and lack of physical activity which has begun to characterise the lifestyle in developed countries &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Medication===&lt;br /&gt;
Studies have shown that valproic acid in medication used to treat epilepsy and bipolar disorders contributes to the development of PCOS. Women with these disorders  may develop the typical features of PCOS such as polycystic ovaries, anovulation, hyperandrogenism and obesity &amp;lt;ref name=quartre&amp;gt;&amp;lt;pubmed&amp;gt;8413434&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Recent studies also suggest that the weight gain from medication is significant as it can lead to the development of PCOS &amp;lt;ref name=deux/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=Pathogenesis=&lt;br /&gt;
&lt;br /&gt;
The pathogenesis of polycystic ovarian syndrome is poorly understood, however it is believed that insulin resistance and excess androgens such as testosterone play a fundamental role.&lt;br /&gt;
Underlying factors such as obesity and genetic predispositions likely contribute to the onset of polycystic ovarian syndrome through the development of a combination of hyperinsulinemia and hyperandrogenemia.&amp;lt;ref name=eleven&amp;gt;&amp;lt;pubmed&amp;gt;PMC4556908&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Hyperinsulinemia&amp;lt;/u&amp;gt;===&lt;br /&gt;
&lt;br /&gt;
Hyperinsulinemia is a term that defines the presence of excessive amounts of insulin in the blood relative to the amount of glucose. &amp;lt;ref name=fourteen&amp;gt;&amp;lt;pubmed&amp;gt;PMC4114053&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; This phenomenon is typically associated with obesity and excess adipose tissue, both of which are associated with insulin resistance. In order to overcome this resistance, insulin secretion is increased in an attempt to normalise blood glucose levels, thereby leading to hyperinsulineamia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC2782313&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; Excessive levels of insulin typically cause disruption to the hypothalamus-hypophysis-ovary axis whilst insulin resistance in ovarian tissues leads to decreased metabolic signalling. However, steroidogenic activity is largely unaffected by the impaired metabolic signalling, thereby paving the way androgens to become more effect and paving the way towards hyperandrogenemia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
[[File:Patholophysiology of Polycystic Ovarian Syndrome.jpg|500px|thumb|left|The impact of hyperinsulinemia and hyperandrogenemia on the development of polycystic ovarian syndrome]]&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Hyperandrogenemia&amp;lt;/u&amp;gt;===&lt;br /&gt;
&lt;br /&gt;
Hyperandrogenemia is a hallmark of the development of polycystic ovarian syndrome, with 80% of women presenting with excess androgen also having polycystic ovaries.&amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; The disruption of the hypothalamus hypophysis ovary axis as a result of hyperinsulinemia increases the release of GnRH and LH, leading to increased androgen production in the ovarian theca cells. Hyperandrogenemia decreases the feedback sensitivity of both estradiol and progesterone within gonadotropic hypothalmic cells. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; A deficiency of FSH is observed and correlates with the increased secretion of GnRH and LH. As a result of this deficiency, graunlosa  cell aromatisation to oestrogens as well as follicle maturation and ovulation will be drastically impaired.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3453528&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
As a consequence of the impairment of follicle maturation, small antral follicles will accumulate within the periphery of the ovary and develop a cystic morphology. Ovulation will be unable to occur due to the absence of mature follicles, culminating in infertility.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4562327&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Hyperandrogenism&amp;lt;/u&amp;gt;===&lt;br /&gt;
&lt;br /&gt;
====Animal Models====&lt;br /&gt;
&lt;br /&gt;
Studies conducted on female rhesus monkeys have supported evidence for the foetal origins of the clinical features of PCOS &amp;lt;ref name=h1&amp;gt;&amp;lt;pubmed&amp;gt;18406243&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.  It has been shown that in human females, an excess of androgen exposure at any stage from the development of the ovaries to the onset of puberty manifests as characteristic features of PCOS, such as resistance to insulin and Luteinising Hormone (LH) hypersecretion. After exposure to levels of testosterone matching those of fetal males, in utero, female rhesus monkeys were found to display the clinical and biochemical features typical of PCOS such as hypersecretion of LH and abnormal insulin action. These results correlated to those of similar studies conducted on sheep, where the pregnant ewe was exposed to excessive levels of testosterone and LH secretion and abnormality in ovarian cycles were again prominent features &amp;lt;ref name=sheep&amp;gt;Padmanabhan V, Evans NP, Taylor JA, Robinson JE1997 '''Prenatal exposure to  androgens  leads  to  the  development  of  cystic  ovaries  in  the  sheep'''. Biol Reprod 56:194&amp;lt;/ref&amp;gt;. While these studies indicate that similar biochemical and clinical manifestations in humans originate from excess androgen exposure of the female fetus, it must be noted that it is very unlikely for any excess androgen production to be passed across the placenta from the mother to her daughter. This is because mechanisms such as androgen binding proteins and placental metabolism of androgen prevent excess androgen entering the circulation of the fetus &amp;lt;ref name=h2&amp;gt;&amp;lt;pubmed&amp;gt;12098657&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
====Cell Culture Models====&lt;br /&gt;
&lt;br /&gt;
While studies have shown that the adrenal could be a source of excess androgen such as the adrenal &amp;lt;ref name=h3&amp;gt;&amp;lt;pubmed&amp;gt;7962325&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;, they were followed by various studies using cell culture models which demonstrated that the ovary was the major source of excess androgen &amp;lt;ref name=h4/&amp;gt; &amp;lt;ref name=h5&amp;gt;&amp;lt;pubmed&amp;gt;9302378&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. ''In vitro'' studies have shown that the production of steroids is abnormal in theca cells &amp;lt;ref name=h3/&amp;gt;. In women affected by PCOS, stimulation by human chorionic gonadotrophin (hCG) is followed by an increase in thecal steroid production after suppression of LH by a GnRH analogue &amp;lt;ref name=h5/&amp;gt;. Theca cells cultured from polycystic ovaries produce 20 times as much androstenedione as those from normal ovaries &amp;lt;ref name=h4/&amp;gt; with increased expression of mRNA for enzymes responsible for making steroids also reported in following studies. &amp;lt;ref name=h6&amp;gt;&amp;lt;pubmed&amp;gt;10852468&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; These results have prompted many studies on genes encoding these steroidogeneic enzymes.&lt;br /&gt;
&lt;br /&gt;

===&amp;lt;u&amp;gt;The Genetics of Infertility: Current Status of the Field&amp;lt;/u&amp;gt;===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3885174&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article attempted to determine the role that genetics plays in female infertility. It was noted that several prominent causes of female infertility such as Galactosemia and Primary Ovarian Failure (POF) were associated with specific genes, with the GALT gene contributing to the former condition and the FMR1 gene contributing to the latter.&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Causes of Sterility in Bosnia-Herzegovina Population&amp;lt;/u&amp;gt;===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC4499307&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
The study conducted as laid out in this article examined the causes of female sterility in the Bosnia-Herzegovina population. Married participants were arranged into various groups based upon their age. The experiment came to the conclusion that in approximately 42% of infertile married couples, female sterility was the primary cause. The two primary causes of female infertility were tubal deficiencies (31% of cases) and Diminished Ovarian Reserves (38% of cases)&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Epidemiology, diagnosis, and management of polycystic ovary syndrome&amp;lt;/u&amp;gt;===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This research article examines the causes of polycystic ovary syndrome (POS), a common cause of infertility in women. The article concluded that 50-70% of women suffer from insulin resistance secondary to Type 2 Diabetes and in many cases obseity, which may contribute partially to POS. Furthermore, 85-90% of women with oligomenorrhea also had POS, suggesting that it is an underlying cause. However, the exact pathophysiology of POS was not determined.&lt;br /&gt;
&lt;br /&gt;
=Signs and Symptoms=&lt;br /&gt;
&lt;br /&gt;
The symptoms of PCOS are different for each women. The three cardinal signs of PCOS are hyperandrogenism, polycystic ovaries and ovarian dysfunction &amp;lt;ref name=sign1&amp;gt;&amp;lt;pubmed&amp;gt;14688154&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Common clinical symptoms include &amp;lt;ref&amp;gt; Women's Heath, U.S. Department of Health and Human Services ,[ http://www.womenshealth.gov/publications/our-publications/fact-sheet/polycystic-ovary-syndrome.html#d ], 'Polycystic ovary syndrome (PCOS) fact sheet'&amp;lt;/ref&amp;gt; ;&lt;br /&gt;
&lt;br /&gt;
* Infertility- due to anovulation caused by PCOS. &lt;br /&gt;
* Irregular Menstrual Cycles&lt;br /&gt;
* Hirsutism&lt;br /&gt;
* Ovarian Cysts&lt;br /&gt;
* Obesity&lt;br /&gt;
* Male Pattern Baldness&lt;br /&gt;
* Skin Tags&lt;br /&gt;
* Pelvic Pain&lt;br /&gt;
&lt;br /&gt;
Along with obesity, PCOS is also associated with other metabolic issues such as insulin resistance, hyperinsulinemia and type 2 diabetes mellitus. It has also been associated with cardiovascular problems and cancers of the breast and endometrium &amp;lt;ref name=sign3&amp;gt;&amp;lt;pubmed&amp;gt;PMC4341818&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=Diagnosis=&lt;br /&gt;
&lt;br /&gt;
A major diagnostic tool for PCOS is a pelvic ultrasound, but PCOS diagnosis cannot be completely dependent on just pelvic ultrasounds. A patient with PCOS may not necessarily have polycystic ovaries, and those with ovarian cysts may not necessarily have PCOS. A range of diagnostic assessments and associated symptoms have to be thoroughly investigated.&lt;br /&gt;
&lt;br /&gt;
===Medical history and examination===&lt;br /&gt;
Clinical questions are asked or filled out in the form of a questionnaire to assess and assist in the diagnosis of PCOS. Studies show that those with a history:&lt;br /&gt;
*infrequent and irregular menstruation&lt;br /&gt;
*hirsutism (related to high levels of androgens in the blood – hyperandrogenism)&lt;br /&gt;
*obesity&lt;br /&gt;
*acne production &lt;br /&gt;
are at a higher predictive risk of PCOS. But questions regarding failed pregnancy attempts and history of nipple discharge proved no correlation in diagnosing PCOS. &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/17872783 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Blood Test===&lt;br /&gt;
A patient with elevated levels of androgens, a medical condition called &amp;lt;b&amp;gt;hyperandrogenism &amp;lt;/b&amp;gt;, is very highly likely to have PCOS. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/20591140 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&amp;lt;b&amp;gt; Androgens &amp;lt;/b&amp;gt; , such as testosterone, and &amp;lt;b&amp;gt;free androgen index (FAI) &amp;lt;/b&amp;gt; are the two tests best used in diagnosing hyperandrogenism.&lt;br /&gt;
Androgen excess in PCOS is a result from increased synthesis and release of ovarian androgens. &amp;lt;b&amp;gt;Dehydroepiandrosterone sulfate &amp;lt;/b&amp;gt; (DHEA-S) levels are used as a biomarker for testing androgen levels, as it is made exclusively by the adrenal glands. DHEA-S levels of above 1890 micromol/L is extremely suggestive of hyperandrogenism. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/18844715 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&amp;lt;b&amp;gt;Free androgen index (FAI) &amp;lt;/b&amp;gt; is the ratio of total testosterone measurement to levels of &amp;lt;b&amp;gt; sex hormone-binding globulin &amp;lt;/b&amp;gt; (SHBG). Those with PCOS will have high FAI, as this indicates a high ration of free testosterone in the body.&lt;br /&gt;
Other blood tests are also done to help exclude other predisposing factors such as levels of &amp;lt;b&amp;gt; Thyroid Stimulating Hormone &amp;lt;/b&amp;gt; (LSH) and &amp;lt;b&amp;gt; Follicle-stimulating hormone &amp;lt;/b&amp;gt; (FSH). An elevated ratio of LSH to FSH, of above 2:1 &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/14737959 &amp;lt;/ref&amp;gt;, indicates a possibility, but not definitively, of PCOS.&lt;br /&gt;
The effect of &amp;lt;b&amp;gt; insulin &amp;lt;/b&amp;gt; on blood can also be tested for insulin resistance. Insulin resistance enhances androgen production and increases free androgen levels by reducing SHBG. This can used as an indication marker for the possibility of PCOS&lt;br /&gt;
A study in 2014 showed that &amp;lt;b&amp;gt; Anti-Müllerian hormone &amp;lt;/b&amp;gt; (AMH) is found to be elevated in patients with PCOS &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24821925 &amp;lt;/ref&amp;gt;, giving rise to its potential clinical implication in diagnosing PCOS. AMH is exclusively produced in ovarian follicles, with individual AMH concentration reflecting the quantity of remaining primordial follicles and measure of ovarian reserve. &lt;br /&gt;
&lt;br /&gt;
===Gynecologic ultrasonography===&lt;br /&gt;
Gynecologic ultrasonography is a pelvic ultrasound, specifically to the female pelvic region, with regards to the uterus, ovaries and the fallopian tube. The examination can be performed by transabdominal ultrasonography, with a full bladder, or transvaginal ultrasonography with a vaginal transducer. Typically transvaginal imaging shows a better and clearer image than transabdominal ultrasonography, as it uses higher frequency imaging, but is limited to areas it can reach. In the case of PCOS, both techniques can provide an image of the ovaries. Studies suggest that if more than 25 follicles are seen in an ovary, predominantly in the periphery, in women between 18-35 years, it is described to have a polycystic ovarian morphology. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24345633 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Magnetic Resonance Imaging===&lt;br /&gt;
Ovaries can also be seen on MRIs. On MRIs, PCOS is characterized by numberous peripheral cysts where the ovaries affected to be slightly larger than normal. Although MRI is seen to be effective in ovarian imaging, the finding of peripheral ovarian cysts in MRIsmay not be PCOS specific. &amp;lt;ref&amp;gt;  http://www.ncbi.nlm.nih.gov/pubmed/8888256 &amp;lt;/ref&amp;gt; But studies have seen that MR imaging in adolescence uncover distinct differences between young patients with and without PCOS &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/23292744 &amp;lt;/ref&amp;gt;, with also great diagnostic sensitivity with patients between the age of 21-30 &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/19241321 &amp;lt;/ref&amp;gt;, providing assistance of imagery in patients whom may be opposed to transvaginal ultrasounds.&lt;br /&gt;
&lt;br /&gt;
=Prevention=&lt;br /&gt;
&lt;br /&gt;
==Impact of physical activity on ovarian reserve markers in normal, overweight and obese reproductive age women==&lt;br /&gt;
&amp;lt;pubmed&amp;gt;25509968&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study focuses on the effect of physical activity on fertility in three groups of women at reproductive age; normal, overweight and obese. The results from the study suggest that there was a marked improvement in fertility as shown by the ovarian reserve markers for all 3 groups, however it was most significant in the overweight and obese groups. This study is relevant to our project as it gives an insight into the preventative measures that can be taken for infertility. &lt;br /&gt;
&lt;br /&gt;
==Risk factors of polycystic ovarian syndrome among Li People==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;26276294&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study examined the risk factors entailed in Polycystic Ovarian Syndrdome (PCOS) amoung Li people. Using the method of a case control study, questionnaires were given to female Li people with and without PCOS. Analysis of the questionnaires showed that family history of diabetes, family history of infertility, bad mood, lack of physical exercise are all high risk factors of PCOS. As a result, management of these risk factors can be taken into consideration when preventing infertility through PCOS.&lt;br /&gt;
&lt;br /&gt;
==Vitamin D and female fertility==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;24717915&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article is a review focusing on research regarding Vitamin D and fertility over the past year. The review found that the levels of Vitamin D is crucial for women undergoing in-vitro fertilisation. It  was also found that Vitamin D was beneficial for women with PCOS and carried a protective effect against endometriosis. These observations suggest that having sufficient Vitamin D in your body can be preventative for problems associated with fertility.&lt;br /&gt;

| '''CURRENT TREATMENT'''&lt;br /&gt;
| '''DISADVANTAGES'''&lt;br /&gt;
|-&lt;br /&gt;
| General Practitioners tend to prescribe oral anti-oestrogens, most commonly the contraceptive pill, to restore ovulation.&lt;br /&gt;
| This method only has a 50% success rate in PCOS patients. It does not directly increase fertility rates, but restores the menstrual cycle.&lt;br /&gt;
 &lt;br /&gt;
|-bgcolor=&amp;quot;FAF5FF&amp;quot;&lt;br /&gt;
| Lifestyle changes are highly encouraged by medical practitioners. Diet and exercise regimes can be designed with a dietitian or nutritionist. &lt;br /&gt;
| Exercise and diet plans do not directly increase fertility. They are designed to enhance weight loss, which in some patients can encourage normal hormone levels from the pituitary and thyroid. &lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| Clomiphene citrate administration (generally in pill form, as prescribed by a GP). Such pills stimulate the pituitary gland to release GnRH to simulate ovulation (with a 72% success rate in the ___ trial). &lt;br /&gt;
| Clomiphene can cause multiple side effects, most notably abnormal uterine bleeding and pelvic pain to due enlargement of the ovaries. &lt;br /&gt;
&lt;br /&gt;
Thus, it cannot be as frequently prescribed as the contraceptive pill, and careful patient monitoring is imperative. &lt;br /&gt;
&lt;br /&gt;
|-bgcolor=&amp;quot;FAF5FF&amp;quot;&lt;br /&gt;
| Higher fertility rates are observed in treatments combining clomiphene citrate and metformin (79% success).&lt;br /&gt;
| Similar disadvantages as clomiphene, above.&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
===New Trials===&lt;br /&gt;
&lt;br /&gt;
Some studies have found that regular Selenium supplements can encourage fertility among PCOS patients. The program, which is still in its early trial period, requires women to consume selenium tablets for 8 weeks. This study has found a significant decrease in dehydroepiandrosterone (DHEA) levels in patients, thus reducing excessive hair growth associated with PCOS. A direct link to increased fertility is yet to be established, and thus further testing is required.&lt;br /&gt;

=Female Infertility=&lt;br /&gt;
&lt;br /&gt;
[[File:Prevalence of Primary Infertility in 2010.jpeg|400px|thumb|right|Prevalence of Primary Infertility in 2010]]&lt;br /&gt;
&lt;br /&gt;
Female Infertility refers to the failure to conceive after one year of regular unprotected intercourse in females &amp;lt;ref name=one&amp;gt;&amp;lt;pubmed&amp;gt;26150870&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. In 2010, infertility affected 48.5 million couples world wide and the areas of highest prevalence included North Africa and Middle East, South Asia, Central/Eastern Europe and Central Asia and Sub-Saharan Africa &amp;lt;ref name=two&amp;gt;&amp;lt;pubmed&amp;gt;23271957&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. As there are several causes of female infertility, we will be focusing on infertility that is caused by '''Polycystic Ovarian Syndrome''' (PCOS), the most common cause of infertility that is medically treatable &amp;lt;ref name=one/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Polycystic Ovarian Syndrome==&lt;br /&gt;
Polycystic Ovarian Syndrome (PCOS) is a common endocrine disorder, affecting up to 20% of reproductive aged women [3] It is the most common cause of anovulatory infertility [1] which refers to infertility caused by the the absence of ovulation.&lt;br /&gt;
&lt;br /&gt;
=Causes=&lt;br /&gt;
&lt;br /&gt;
PCOS is a disorder of heterogeneous origin with unknown aetiology &amp;lt;ref name=four&amp;gt;&amp;lt;pubmed&amp;gt;21896560&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Studies have shown that both genetic and environmental factors contribute to the development of PCOS in women however there is limited research into the actual interactions between these two factors &amp;lt;ref name=un&amp;gt;&amp;lt;pubmed&amp;gt;17185788&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Genetic Factors===&lt;br /&gt;
&lt;br /&gt;
Despite the lack of information regarding its aetiology, there is increasing evidence for a genetic involvement in the endocrine disorder. Studies have shown that genes play an important role in contributing towards the clinical and biochemical features of the disease &amp;lt;ref name=four/&amp;gt;. This evidence includes the family clustering of cases, greater unanimity between monozygotic twins than heterozygotic twins and the ability to inherit endocrine and  metabolic features of PCOS &amp;lt;ref name=four/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
In one study, 115 sisters of women with PCOS were examined and results showed that half of these sisters had high testosterone levels, suggesting that hyperandrogenemia is a common trait with a dominant pattern of inheritance. These results strongly supported the idea of the familial clustering of biochemical features such as hyperandrogenism in first degree relatives &amp;lt;ref name=deux&amp;gt;&amp;lt;pubmed&amp;gt;9843997&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
Several genes have been considered to play an important role in the development of PCOS such as CYP11A, the insulin gene, the follistatin gene and a region near the insulin receptor gene. Yet, the evidence supporting most of these genes has been refuted by larger studies, except for the region near the insulin receptor gene &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
There has been strong evidence linking the gene CYP11a with hyperandrogenism in women with PCOS. &amp;lt;ref name=cinq&amp;gt;&amp;lt;pubmed&amp;gt;9147642&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; While it doesn't isolate this gene as the sole cause of PCOS, variation of the genotype at this locus contributes to production of excess androgen &amp;lt;ref name=h4&amp;gt;&amp;lt;pubmed&amp;gt;7962289&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Studies have also shown that there is strong evidence for linkage between the alleles at the Variable Number Tandem Repeats (VNTR) which is situated 5' to the insulin gene and PCOS. The data from the study suggests that it is a very susceptible region in PCOS and also may play a role in the development of hyperinsulinaemia &amp;lt;ref name=trois&amp;gt;&amp;lt;pubmed&amp;gt;9455828&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
===Environmental Factors===&lt;br /&gt;
The prevalence of PCOS in populations where there has been a constant gene pool indicates that environmental factors play a significant role in the aetiology of PCOS.&lt;br /&gt;
&lt;br /&gt;
===Obesity and Diet===&lt;br /&gt;
Obesity is the major environmental factor driving the development of PCOS in susceptible individuals. The rising rates of PCOS have been paralleled by the widespread emergence of obesity and type 2 diabetes which are prevalent in developed countries. The risk of developing PCOS from obesity is compounded by  poor dietary choices and lack of physical activity which has begun to characterise the lifestyle in developed countries &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Medication===&lt;br /&gt;
Studies have shown that valproic acid in medication used to treat epilepsy and bipolar disorders contributes to the development of PCOS. Women with these disorders  may develop the typical features of PCOS such as polycystic ovaries, anovulation, hyperandrogenism and obesity &amp;lt;ref name=quartre&amp;gt;&amp;lt;pubmed&amp;gt;8413434&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Recent studies also suggest that the weight gain from medication is significant as it can lead to the development of PCOS &amp;lt;ref name=deux/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=Pathogenesis=&lt;br /&gt;
&lt;br /&gt;
The pathogenesis of polycystic ovarian syndrome is poorly understood, however it is believed that insulin resistance and excess androgens such as testosterone play a fundamental role.&lt;br /&gt;
Underlying factors such as obesity and genetic predispositions likely contribute to the onset of polycystic ovarian syndrome through the development of a combination of hyperinsulinemia and hyperandrogenemia.&amp;lt;ref name=eleven&amp;gt;&amp;lt;pubmed&amp;gt;PMC4556908&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Hyperinsulinemia&amp;lt;/u&amp;gt;===&lt;br /&gt;
&lt;br /&gt;
Hyperinsulinemia is a term that defines the presence of excessive amounts of insulin in the blood relative to the amount of glucose. &amp;lt;ref name=fourteen&amp;gt;&amp;lt;pubmed&amp;gt;PMC4114053&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; This phenomenon is typically associated with obesity and excess adipose tissue, both of which are associated with insulin resistance. In order to overcome this resistance, insulin secretion is increased in an attempt to normalise blood glucose levels, thereby leading to hyperinsulineamia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC2782313&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; Excessive levels of insulin typically cause disruption to the hypothalamus-hypophysis-ovary axis whilst insulin resistance in ovarian tissues leads to decreased metabolic signalling. However, steroidogenic activity is largely unaffected by the impaired metabolic signalling, thereby paving the way androgens to become more effect and paving the way towards hyperandrogenemia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
[[File:Patholophysiology of Polycystic Ovarian Syndrome.jpg|500px|thumb|left|The impact of hyperinsulinemia and hyperandrogenemia on the development of polycystic ovarian syndrome]]&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Hyperandrogenemia&amp;lt;/u&amp;gt;===&lt;br /&gt;
&lt;br /&gt;
Hyperandrogenemia is a hallmark of the development of polycystic ovarian syndrome, with 80% of women presenting with excess androgen also having polycystic ovaries.&amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; The disruption of the hypothalamus hypophysis ovary axis as a result of hyperinsulinemia increases the release of GnRH and LH, leading to increased androgen production in the ovarian theca cells. Hyperandrogenemia decreases the feedback sensitivity of both estradiol and progesterone within gonadotropic hypothalmic cells. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; A deficiency of FSH is observed and correlates with the increased secretion of GnRH and LH. As a result of this deficiency, graunlosa  cell aromatisation to oestrogens as well as follicle maturation and ovulation will be drastically impaired.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3453528&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
As a consequence of the impairment of follicle maturation, small antral follicles will accumulate within the periphery of the ovary and develop a cystic morphology. Ovulation will be unable to occur due to the absence of mature follicles, culminating in infertility.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4562327&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Hyperandrogenism&amp;lt;/u&amp;gt;===&lt;br /&gt;
&lt;br /&gt;
====Animal Models====&lt;br /&gt;
&lt;br /&gt;
Studies conducted on female rhesus monkeys have supported evidence for the foetal origins of the clinical features of PCOS &amp;lt;ref name=h1&amp;gt;&amp;lt;pubmed&amp;gt;18406243&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.  It has been shown that in human females, an excess of androgen exposure at any stage from the development of the ovaries to the onset of puberty manifests as characteristic features of PCOS, such as resistance to insulin and Luteinising Hormone (LH) hypersecretion. After exposure to levels of testosterone matching those of fetal males, in utero, female rhesus monkeys were found to display the clinical and biochemical features typical of PCOS such as hypersecretion of LH and abnormal insulin action. These results correlated to those of similar studies conducted on sheep, where the pregnant ewe was exposed to excessive levels of testosterone and LH secretion and abnormality in ovarian cycles were again prominent features &amp;lt;ref name=sheep&amp;gt;Padmanabhan V, Evans NP, Taylor JA, Robinson JE1997 '''Prenatal exposure to  androgens  leads  to  the  development  of  cystic  ovaries  in  the  sheep'''. Biol Reprod 56:194&amp;lt;/ref&amp;gt;. While these studies indicate that similar biochemical and clinical manifestations in humans originate from excess androgen exposure of the female fetus, it must be noted that it is very unlikely for any excess androgen production to be passed across the placenta from the mother to her daughter. This is because mechanisms such as androgen binding proteins and placental metabolism of androgen prevent excess androgen entering the circulation of the fetus &amp;lt;ref name=h2&amp;gt;&amp;lt;pubmed&amp;gt;12098657&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
====Cell Culture Models====&lt;br /&gt;
&lt;br /&gt;
While studies have shown that the adrenal could be a source of excess androgen such as the adrenal &amp;lt;ref name=h3&amp;gt;&amp;lt;pubmed&amp;gt;7962325&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;, they were followed by various studies using cell culture models which demonstrated that the ovary was the major source of excess androgen &amp;lt;ref name=h4/&amp;gt; &amp;lt;ref name=h5&amp;gt;&amp;lt;pubmed&amp;gt;9302378&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. ''In vitro'' studies have shown that the production of steroids is abnormal in theca cells &amp;lt;ref name=h3/&amp;gt;. In women affected by PCOS, stimulation by human chorionic gonadotrophin (hCG) is followed by an increase in thecal steroid production after suppression of LH by a GnRH analogue &amp;lt;ref name=h5/&amp;gt;. Theca cells cultured from polycystic ovaries produce 20 times as much androstenedione as those from normal ovaries &amp;lt;ref name=h4/&amp;gt; with increased expression of mRNA for enzymes responsible for making steroids also reported in following studies. &amp;lt;ref name=h6&amp;gt;&amp;lt;pubmed&amp;gt;10852468&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; These results have prompted many studies on genes encoding these steroidogeneic enzymes.&lt;br /&gt;
&lt;br /&gt;

===&amp;lt;u&amp;gt;The Genetics of Infertility: Current Status of the Field&amp;lt;/u&amp;gt;===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3885174&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article attempted to determine the role that genetics plays in female infertility. It was noted that several prominent causes of female infertility such as Galactosemia and Primary Ovarian Failure (POF) were associated with specific genes, with the GALT gene contributing to the former condition and the FMR1 gene contributing to the latter.&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Causes of Sterility in Bosnia-Herzegovina Population&amp;lt;/u&amp;gt;===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC4499307&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
The study conducted as laid out in this article examined the causes of female sterility in the Bosnia-Herzegovina population. Married participants were arranged into various groups based upon their age. The experiment came to the conclusion that in approximately 42% of infertile married couples, female sterility was the primary cause. The two primary causes of female infertility were tubal deficiencies (31% of cases) and Diminished Ovarian Reserves (38% of cases)&lt;br /&gt;
&lt;br /&gt;
===&amp;lt;u&amp;gt;Epidemiology, diagnosis, and management of polycystic ovary syndrome&amp;lt;/u&amp;gt;===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This research article examines the causes of polycystic ovary syndrome (POS), a common cause of infertility in women. The article concluded that 50-70% of women suffer from insulin resistance secondary to Type 2 Diabetes and in many cases obseity, which may contribute partially to POS. Furthermore, 85-90% of women with oligomenorrhea also had POS, suggesting that it is an underlying cause. However, the exact pathophysiology of POS was not determined.&lt;br /&gt;
&lt;br /&gt;
=Signs and Symptoms=&lt;br /&gt;
&lt;br /&gt;
The symptoms of PCOS are different for each women. The three cardinal signs of PCOS are hyperandrogenism, polycystic ovaries and ovarian dysfunction &amp;lt;ref name=sign1&amp;gt;&amp;lt;pubmed&amp;gt;14688154&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Common clinical symptoms include &amp;lt;ref&amp;gt; Women's Heath, U.S. Department of Health and Human Services ,[ http://www.womenshealth.gov/publications/our-publications/fact-sheet/polycystic-ovary-syndrome.html#d ], 'Polycystic ovary syndrome (PCOS) fact sheet'&amp;lt;/ref&amp;gt; ;&lt;br /&gt;

&lt;br /&gt;
Along with obesity, PCOS is also associated with other metabolic issues such as insulin resistance, hyperinsulinemia and type 2 diabetes mellitus. It has also been associated with cardiovascular problems and cancers of the breast and endometrium &amp;lt;ref name=sign3&amp;gt;&amp;lt;pubmed&amp;gt;PMC4341818&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=Diagnosis=&lt;br /&gt;
&lt;br /&gt;
A major diagnostic tool for PCOS is a pelvic ultrasound, but PCOS diagnosis cannot be completely dependent on just pelvic ultrasounds. A patient with PCOS may not necessarily have polycystic ovaries, and those with ovarian cysts may not necessarily have PCOS. A range of diagnostic assessments and associated symptoms have to be thoroughly investigated.&lt;br /&gt;
&lt;br /&gt;
===Medical history and examination===&lt;br /&gt;
Clinical questions are asked or filled out in the form of a questionnaire to assess and assist in the diagnosis of PCOS. Studies show that those with a history:&lt;br /&gt;
*infrequent and irregular menstruation&lt;br /&gt;
*hirsutism (related to high levels of androgens in the blood – hyperandrogenism)&lt;br /&gt;
*obesity&lt;br /&gt;
*acne production &lt;br /&gt;
are at a higher predictive risk of PCOS. But questions regarding failed pregnancy attempts and history of nipple discharge proved no correlation in diagnosing PCOS. &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/17872783 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Blood Test===&lt;br /&gt;
A patient with elevated levels of androgens, a medical condition called &amp;lt;b&amp;gt;hyperandrogenism &amp;lt;/b&amp;gt;, is very highly likely to have PCOS. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/20591140 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&amp;lt;b&amp;gt; Androgens &amp;lt;/b&amp;gt; , such as testosterone, and &amp;lt;b&amp;gt;free androgen index (FAI) &amp;lt;/b&amp;gt; are the two tests best used in diagnosing hyperandrogenism.&lt;br /&gt;
Androgen excess in PCOS is a result from increased synthesis and release of ovarian androgens. &amp;lt;b&amp;gt;Dehydroepiandrosterone sulfate &amp;lt;/b&amp;gt; (DHEA-S) levels are used as a biomarker for testing androgen levels, as it is made exclusively by the adrenal glands. DHEA-S levels of above 1890 micromol/L is extremely suggestive of hyperandrogenism. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/18844715 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&amp;lt;b&amp;gt;Free androgen index (FAI) &amp;lt;/b&amp;gt; is the ratio of total testosterone measurement to levels of &amp;lt;b&amp;gt; sex hormone-binding globulin &amp;lt;/b&amp;gt; (SHBG). Those with PCOS will have high FAI, as this indicates a high ration of free testosterone in the body.&lt;br /&gt;
Other blood tests are also done to help exclude other predisposing factors such as levels of &amp;lt;b&amp;gt; Thyroid Stimulating Hormone &amp;lt;/b&amp;gt; (LSH) and &amp;lt;b&amp;gt; Follicle-stimulating hormone &amp;lt;/b&amp;gt; (FSH). An elevated ratio of LSH to FSH, of above 2:1 &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/14737959 &amp;lt;/ref&amp;gt;, indicates a possibility, but not definitively, of PCOS.&lt;br /&gt;
The effect of &amp;lt;b&amp;gt; insulin &amp;lt;/b&amp;gt; on blood can also be tested for insulin resistance. Insulin resistance enhances androgen production and increases free androgen levels by reducing SHBG. This can used as an indication marker for the possibility of PCOS&lt;br /&gt;
A study in 2014 showed that &amp;lt;b&amp;gt; Anti-Müllerian hormone &amp;lt;/b&amp;gt; (AMH) is found to be elevated in patients with PCOS &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24821925 &amp;lt;/ref&amp;gt;, giving rise to its potential clinical implication in diagnosing PCOS. AMH is exclusively produced in ovarian follicles, with individual AMH concentration reflecting the quantity of remaining primordial follicles and measure of ovarian reserve. &lt;br /&gt;
&lt;br /&gt;
===Gynecologic ultrasonography===&lt;br /&gt;
Gynecologic ultrasonography is a pelvic ultrasound, specifically to the female pelvic region, with regards to the uterus, ovaries and the fallopian tube. The examination can be performed by transabdominal ultrasonography, with a full bladder, or transvaginal ultrasonography with a vaginal transducer. Typically transvaginal imaging shows a better and clearer image than transabdominal ultrasonography, as it uses higher frequency imaging, but is limited to areas it can reach. In the case of PCOS, both techniques can provide an image of the ovaries. Studies suggest that if more than 25 follicles are seen in an ovary, predominantly in the periphery, in women between 18-35 years, it is described to have a polycystic ovarian morphology. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24345633 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Magnetic Resonance Imaging===&lt;br /&gt;
Ovaries can also be seen on MRIs. On MRIs, PCOS is characterized by numberous peripheral cysts where the ovaries affected to be slightly larger than normal. Although MRI is seen to be effective in ovarian imaging, the finding of peripheral ovarian cysts in MRIsmay not be PCOS specific. &amp;lt;ref&amp;gt;  http://www.ncbi.nlm.nih.gov/pubmed/8888256 &amp;lt;/ref&amp;gt; But studies have seen that MR imaging in adolescence uncover distinct differences between young patients with and without PCOS &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/23292744 &amp;lt;/ref&amp;gt;, with also great diagnostic sensitivity with patients between the age of 21-30 &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/19241321 &amp;lt;/ref&amp;gt;, providing assistance of imagery in patients whom may be opposed to transvaginal ultrasounds.&lt;br /&gt;
&lt;br /&gt;
=Prevention=&lt;br /&gt;
&lt;br /&gt;
==Impact of physical activity on ovarian reserve markers in normal, overweight and obese reproductive age women==&lt;br /&gt;
&amp;lt;pubmed&amp;gt;25509968&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study focuses on the effect of physical activity on fertility in three groups of women at reproductive age; normal, overweight and obese. The results from the study suggest that there was a marked improvement in fertility as shown by the ovarian reserve markers for all 3 groups, however it was most significant in the overweight and obese groups. This study is relevant to our project as it gives an insight into the preventative measures that can be taken for infertility. &lt;br /&gt;
&lt;br /&gt;
==Risk factors of polycystic ovarian syndrome among Li People==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;26276294&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study examined the risk factors entailed in Polycystic Ovarian Syndrdome (PCOS) amoung Li people. Using the method of a case control study, questionnaires were given to female Li people with and without PCOS. Analysis of the questionnaires showed that family history of diabetes, family history of infertility, bad mood, lack of physical exercise are all high risk factors of PCOS. As a result, management of these risk factors can be taken into consideration when preventing infertility through PCOS.&lt;br /&gt;
&lt;br /&gt;
==Vitamin D and female fertility==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;24717915&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article is a review focusing on research regarding Vitamin D and fertility over the past year. The review found that the levels of Vitamin D is crucial for women undergoing in-vitro fertilisation. It  was also found that Vitamin D was beneficial for women with PCOS and carried a protective effect against endometriosis. These observations suggest that having sufficient Vitamin D in your body can be preventative for problems associated with fertility.&lt;br /&gt;

| '''CURRENT TREATMENT'''&lt;br /&gt;
| '''DISADVANTAGES'''&lt;br /&gt;
|-&lt;br /&gt;
| General Practitioners tend to prescribe oral anti-oestrogens, most commonly the contraceptive pill, to restore ovulation.&lt;br /&gt;
| This method only has a 50% success rate in PCOS patients. It does not directly increase fertility rates, but restores the menstrual cycle.&lt;br /&gt;
 &lt;br /&gt;
|-bgcolor=&amp;quot;FAF5FF&amp;quot;&lt;br /&gt;
| Lifestyle changes are highly encouraged by medical practitioners. Diet and exercise regimes can be designed with a dietitian or nutritionist. &lt;br /&gt;
| Exercise and diet plans do not directly increase fertility. They are designed to enhance weight loss, which in some patients can encourage normal hormone levels from the pituitary and thyroid. &lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| Clomiphene citrate administration (generally in pill form, as prescribed by a GP). Such pills stimulate the pituitary gland to release GnRH to simulate ovulation (with a 72% success rate in the ___ trial). &lt;br /&gt;
| Clomiphene can cause multiple side effects, most notably abnormal uterine bleeding and pelvic pain to due enlargement of the ovaries. &lt;br /&gt;
&lt;br /&gt;
Thus, it cannot be as frequently prescribed as the contraceptive pill, and careful patient monitoring is imperative. &lt;br /&gt;
&lt;br /&gt;
|-bgcolor=&amp;quot;FAF5FF&amp;quot;&lt;br /&gt;
| Higher fertility rates are observed in treatments combining clomiphene citrate and metformin (79% success).&lt;br /&gt;
| Similar disadvantages as clomiphene, above.&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
===New Trials===&lt;br /&gt;
&lt;br /&gt;
Some studies have found that regular Selenium supplements can encourage fertility among PCOS patients. The program, which is still in its early trial period, requires women to consume selenium tablets for 8 weeks. This study has found a significant decrease in dehydroepiandrosterone (DHEA) levels in patients, thus reducing excessive hair growth associated with PCOS. A direct link to increased fertility is yet to be established, and thus further testing is required.&lt;br /&gt;

=Female Infertility=&lt;br /&gt;
&lt;br /&gt;
[[File:Prevalence of Primary Infertility in 2010.jpeg|400px|thumb|right|Prevalence of Primary Infertility in 2010]]&lt;br /&gt;
&lt;br /&gt;
Female Infertility refers to the failure to conceive after one year of regular unprotected intercourse in females &amp;lt;ref name=one&amp;gt;&amp;lt;pubmed&amp;gt;26150870&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. In 2010, infertility affected 48.5 million couples world wide and the areas of highest prevalence included North Africa and Middle East, South Asia, Central/Eastern Europe and Central Asia and Sub-Saharan Africa &amp;lt;ref name=two&amp;gt;&amp;lt;pubmed&amp;gt;23271957&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. As there are several causes of female infertility, we will be focusing on infertility that is caused by '''Polycystic Ovarian Syndrome''' (PCOS), the most common cause of infertility that is medically treatable &amp;lt;ref name=one/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Polycystic Ovarian Syndrome==&lt;br /&gt;
Polycystic Ovarian Syndrome (PCOS) is a common endocrine disorder, affecting up to 20% of reproductive aged women [3] It is the most common cause of anovulatory infertility [1] which refers to infertility caused by the the absence of ovulation.&lt;br /&gt;
&lt;br /&gt;
=Causes=&lt;br /&gt;
&lt;br /&gt;
PCOS is a disorder of heterogeneous origin with unknown aetiology &amp;lt;ref name=four&amp;gt;&amp;lt;pubmed&amp;gt;21896560&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Studies have shown that both genetic and environmental factors contribute to the development of PCOS in women however there is limited research into the actual interactions between these two factors &amp;lt;ref name=un&amp;gt;&amp;lt;pubmed&amp;gt;17185788&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Genetic Factors===&lt;br /&gt;
&lt;br /&gt;
Despite the lack of information regarding its aetiology, there is increasing evidence for a genetic involvement in the endocrine disorder. Studies have shown that genes play an important role in contributing towards the clinical and biochemical features of the disease &amp;lt;ref name=four/&amp;gt;. This evidence includes the family clustering of cases, greater unanimity between monozygotic twins than heterozygotic twins and the ability to inherit endocrine and  metabolic features of PCOS &amp;lt;ref name=four/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
In one study, 115 sisters of women with PCOS were examined and results showed that half of these sisters had high testosterone levels, suggesting that hyperandrogenemia is a common trait with a dominant pattern of inheritance. These results strongly supported the idea of the familial clustering of biochemical features such as hyperandrogenism in first degree relatives &amp;lt;ref name=deux&amp;gt;&amp;lt;pubmed&amp;gt;9843997&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
Several genes have been considered to play an important role in the development of PCOS such as CYP11A, the insulin gene, the follistatin gene and a region near the insulin receptor gene. Yet, the evidence supporting most of these genes has been refuted by larger studies, except for the region near the insulin receptor gene &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
There has been strong evidence linking the gene CYP11a with hyperandrogenism in women with PCOS. &amp;lt;ref name=cinq&amp;gt;&amp;lt;pubmed&amp;gt;9147642&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; While it doesn't isolate this gene as the sole cause of PCOS, variation of the genotype at this locus contributes to production of excess androgen &amp;lt;ref name=h4&amp;gt;&amp;lt;pubmed&amp;gt;7962289&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Studies have also shown that there is strong evidence for linkage between the alleles at the Variable Number Tandem Repeats (VNTR) which is situated 5' to the insulin gene and PCOS. The data from the study suggests that it is a very susceptible region in PCOS and also may play a role in the development of hyperinsulinaemia &amp;lt;ref name=trois&amp;gt;&amp;lt;pubmed&amp;gt;9455828&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
===Environmental Factors===&lt;br /&gt;
The prevalence of PCOS in populations where there has been a constant gene pool indicates that environmental factors play a significant role in the aetiology of PCOS.&lt;br /&gt;
&lt;br /&gt;
===Obesity and Diet===&lt;br /&gt;
Obesity is the major environmental factor driving the development of PCOS in susceptible individuals. The rising rates of PCOS have been paralleled by the widespread emergence of obesity and type 2 diabetes which are prevalent in developed countries. The risk of developing PCOS from obesity is compounded by  poor dietary choices and lack of physical activity which has begun to characterise the lifestyle in developed countries &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Medication===&lt;br /&gt;
Studies have shown that valproic acid in medication used to treat epilepsy and bipolar disorders contributes to the development of PCOS. Women with these disorders  may develop the typical features of PCOS such as polycystic ovaries, anovulation, hyperandrogenism and obesity &amp;lt;ref name=quartre&amp;gt;&amp;lt;pubmed&amp;gt;8413434&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Recent studies also suggest that the weight gain from medication is significant as it can lead to the development of PCOS &amp;lt;ref name=deux/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=Pathogenesis=&lt;br /&gt;
&lt;br /&gt;
The pathogenesis of polycystic ovarian syndrome is poorly understood, however it is believed that insulin resistance and excess androgens such as testosterone play a fundamental role.&lt;br /&gt;
Underlying factors such as obesity and genetic predispositions likely contribute to the onset of polycystic ovarian syndrome through the development of a combination of hyperinsulinemia and hyperandrogenemia.&amp;lt;ref name=eleven&amp;gt;&amp;lt;pubmed&amp;gt;PMC4556908&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
===Hyperinsulinemia===&lt;br /&gt;
&lt;br /&gt;
Hyperinsulinemia is a term that defines the presence of excessive amounts of insulin in the blood relative to the amount of glucose. &amp;lt;ref name=fourteen&amp;gt;&amp;lt;pubmed&amp;gt;PMC4114053&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; This phenomenon is typically associated with obesity and excess adipose tissue, both of which are associated with insulin resistance. In order to overcome this resistance, insulin secretion is increased in an attempt to normalise blood glucose levels, thereby leading to hyperinsulineamia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC2782313&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; Excessive levels of insulin typically cause disruption to the hypothalamus-hypophysis-ovary axis whilst insulin resistance in ovarian tissues leads to decreased metabolic signalling. However, steroidogenic activity is largely unaffected by the impaired metabolic signalling, thereby paving the way androgens to become more effect and paving the way towards hyperandrogenemia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
[[File:Patholophysiology of Polycystic Ovarian Syndrome.jpg|500px|thumb|left|The impact of hyperinsulinemia and hyperandrogenemia on the development of polycystic ovarian syndrome]]&lt;br /&gt;
&lt;br /&gt;
==Hyperandrogenemia==&lt;br /&gt;
&lt;br /&gt;
Hyperandrogenemia is a hallmark of the development of polycystic ovarian syndrome, with 80% of women presenting with excess androgen also having polycystic ovaries.&amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; The disruption of the hypothalamus hypophysis ovary axis as a result of hyperinsulinemia increases the release of GnRH and LH, leading to increased androgen production in the ovarian theca cells. Hyperandrogenemia decreases the feedback sensitivity of both estradiol and progesterone within gonadotropic hypothalmic cells. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; A deficiency of FSH is observed and correlates with the increased secretion of GnRH and LH. As a result of this deficiency, graunlosa  cell aromatisation to oestrogens as well as follicle maturation and ovulation will be drastically impaired.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3453528&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
As a consequence of the impairment of follicle maturation, small antral follicles will accumulate within the periphery of the ovary and develop a cystic morphology. Ovulation will be unable to occur due to the absence of mature follicles, culminating in infertility.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4562327&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Hyperandrogenism==&lt;br /&gt;
&lt;br /&gt;
====Animal Models====&lt;br /&gt;
&lt;br /&gt;
Studies conducted on female rhesus monkeys have supported evidence for the foetal origins of the clinical features of PCOS &amp;lt;ref name=h1&amp;gt;&amp;lt;pubmed&amp;gt;18406243&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.  It has been shown that in human females, an excess of androgen exposure at any stage from the development of the ovaries to the onset of puberty manifests as characteristic features of PCOS, such as resistance to insulin and Luteinising Hormone (LH) hypersecretion. After exposure to levels of testosterone matching those of fetal males, in utero, female rhesus monkeys were found to display the clinical and biochemical features typical of PCOS such as hypersecretion of LH and abnormal insulin action. These results correlated to those of similar studies conducted on sheep, where the pregnant ewe was exposed to excessive levels of testosterone and LH secretion and abnormality in ovarian cycles were again prominent features &amp;lt;ref name=sheep&amp;gt;Padmanabhan V, Evans NP, Taylor JA, Robinson JE1997 '''Prenatal exposure to  androgens  leads  to  the  development  of  cystic  ovaries  in  the  sheep'''. Biol Reprod 56:194&amp;lt;/ref&amp;gt;. While these studies indicate that similar biochemical and clinical manifestations in humans originate from excess androgen exposure of the female fetus, it must be noted that it is very unlikely for any excess androgen production to be passed across the placenta from the mother to her daughter. This is because mechanisms such as androgen binding proteins and placental metabolism of androgen prevent excess androgen entering the circulation of the fetus &amp;lt;ref name=h2&amp;gt;&amp;lt;pubmed&amp;gt;12098657&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
===Cell Culture Models===&lt;br /&gt;
&lt;br /&gt;
While studies have shown that the adrenal could be a source of excess androgen such as the adrenal &amp;lt;ref name=h3&amp;gt;&amp;lt;pubmed&amp;gt;7962325&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;, they were followed by various studies using cell culture models which demonstrated that the ovary was the major source of excess androgen &amp;lt;ref name=h4/&amp;gt; &amp;lt;ref name=h5&amp;gt;&amp;lt;pubmed&amp;gt;9302378&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. ''In vitro'' studies have shown that the production of steroids is abnormal in theca cells &amp;lt;ref name=h3/&amp;gt;. In women affected by PCOS, stimulation by human chorionic gonadotrophin (hCG) is followed by an increase in thecal steroid production after suppression of LH by a GnRH analogue &amp;lt;ref name=h5/&amp;gt;. Theca cells cultured from polycystic ovaries produce 20 times as much androstenedione as those from normal ovaries &amp;lt;ref name=h4/&amp;gt; with increased expression of mRNA for enzymes responsible for making steroids also reported in following studies. &amp;lt;ref name=h6&amp;gt;&amp;lt;pubmed&amp;gt;10852468&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; These results have prompted many studies on genes encoding these steroidogeneic enzymes.&lt;br /&gt;
&lt;br /&gt;

===The Genetics of Infertility: Current Status of the Field===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3885174&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article attempted to determine the role that genetics plays in female infertility. It was noted that several prominent causes of female infertility such as Galactosemia and Primary Ovarian Failure (POF) were associated with specific genes, with the GALT gene contributing to the former condition and the FMR1 gene contributing to the latter.&lt;br /&gt;
&lt;br /&gt;
===Causes of Sterility in Bosnia-Herzegovina Population===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC4499307&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
The study conducted as laid out in this article examined the causes of female sterility in the Bosnia-Herzegovina population. Married participants were arranged into various groups based upon their age. The experiment came to the conclusion that in approximately 42% of infertile married couples, female sterility was the primary cause. The two primary causes of female infertility were tubal deficiencies (31% of cases) and Diminished Ovarian Reserves (38% of cases)&lt;br /&gt;
&lt;br /&gt;
===Epidemiology, diagnosis, and management of polycystic ovary syndrome===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This research article examines the causes of polycystic ovary syndrome (POS), a common cause of infertility in women. The article concluded that 50-70% of women suffer from insulin resistance secondary to Type 2 Diabetes and in many cases obseity, which may contribute partially to POS. Furthermore, 85-90% of women with oligomenorrhea also had POS, suggesting that it is an underlying cause. However, the exact pathophysiology of POS was not determined.&lt;br /&gt;
&lt;br /&gt;
=Signs and Symptoms=&lt;br /&gt;
&lt;br /&gt;
The symptoms of PCOS are different for each women. The three cardinal signs of PCOS are hyperandrogenism, polycystic ovaries and ovarian dysfunction &amp;lt;ref name=sign1&amp;gt;&amp;lt;pubmed&amp;gt;14688154&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Common clinical symptoms include &amp;lt;ref&amp;gt; Women's Heath, U.S. Department of Health and Human Services ,[ http://www.womenshealth.gov/publications/our-publications/fact-sheet/polycystic-ovary-syndrome.html#d ], 'Polycystic ovary syndrome (PCOS) fact sheet'&amp;lt;/ref&amp;gt; ;&lt;br /&gt;
&lt;br /&gt;
* '''Infertility'''- Due to anovulation caused by PCOS. &lt;br /&gt;
* '''Irregular Menstrual Cycles'''&lt;br /&gt;
* '''Hirsutism'''&lt;br /&gt;

* '''Obesity'''&lt;br /&gt;
* '''Male Pattern Baldness '''&lt;br /&gt;
* '''Skin Tags'''&lt;br /&gt;
* '''Pelvic Pain'''&lt;br /&gt;
&lt;br /&gt;
Along with obesity, PCOS is also associated with other metabolic issues such as insulin resistance, hyperinsulinemia and type 2 diabetes mellitus. It has also been associated with cardiovascular problems and cancers of the breast and endometrium &amp;lt;ref name=sign3&amp;gt;&amp;lt;pubmed&amp;gt;PMC4341818&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=Diagnosis=&lt;br /&gt;
&lt;br /&gt;
A major diagnostic tool for PCOS is a pelvic ultrasound, but PCOS diagnosis cannot be completely dependent on just pelvic ultrasounds. A patient with PCOS may not necessarily have polycystic ovaries, and those with ovarian cysts may not necessarily have PCOS. A range of diagnostic assessments and associated symptoms have to be thoroughly investigated.&lt;br /&gt;
&lt;br /&gt;
===Medical history and examination===&lt;br /&gt;
Clinical questions are asked or filled out in the form of a questionnaire to assess and assist in the diagnosis of PCOS. Studies show that those with a history:&lt;br /&gt;
*infrequent and irregular menstruation&lt;br /&gt;
*hirsutism (related to high levels of androgens in the blood – hyperandrogenism)&lt;br /&gt;
*obesity&lt;br /&gt;
*acne production &lt;br /&gt;
are at a higher predictive risk of PCOS. But questions regarding failed pregnancy attempts and history of nipple discharge proved no correlation in diagnosing PCOS. &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/17872783 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Blood Test===&lt;br /&gt;
A patient with elevated levels of androgens, a medical condition called &amp;lt;b&amp;gt;hyperandrogenism &amp;lt;/b&amp;gt;, is very highly likely to have PCOS. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/20591140 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&amp;lt;b&amp;gt; Androgens &amp;lt;/b&amp;gt; , such as testosterone, and &amp;lt;b&amp;gt;free androgen index (FAI) &amp;lt;/b&amp;gt; are the two tests best used in diagnosing hyperandrogenism.&lt;br /&gt;
Androgen excess in PCOS is a result from increased synthesis and release of ovarian androgens. &amp;lt;b&amp;gt;Dehydroepiandrosterone sulfate &amp;lt;/b&amp;gt; (DHEA-S) levels are used as a biomarker for testing androgen levels, as it is made exclusively by the adrenal glands. DHEA-S levels of above 1890 micromol/L is extremely suggestive of hyperandrogenism. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/18844715 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&amp;lt;b&amp;gt;Free androgen index (FAI) &amp;lt;/b&amp;gt; is the ratio of total testosterone measurement to levels of &amp;lt;b&amp;gt; sex hormone-binding globulin &amp;lt;/b&amp;gt; (SHBG). Those with PCOS will have high FAI, as this indicates a high ration of free testosterone in the body.&lt;br /&gt;
Other blood tests are also done to help exclude other predisposing factors such as levels of &amp;lt;b&amp;gt; Thyroid Stimulating Hormone &amp;lt;/b&amp;gt; (LSH) and &amp;lt;b&amp;gt; Follicle-stimulating hormone &amp;lt;/b&amp;gt; (FSH). An elevated ratio of LSH to FSH, of above 2:1 &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/14737959 &amp;lt;/ref&amp;gt;, indicates a possibility, but not definitively, of PCOS.&lt;br /&gt;
The effect of &amp;lt;b&amp;gt; insulin &amp;lt;/b&amp;gt; on blood can also be tested for insulin resistance. Insulin resistance enhances androgen production and increases free androgen levels by reducing SHBG. This can used as an indication marker for the possibility of PCOS&lt;br /&gt;
A study in 2014 showed that &amp;lt;b&amp;gt; Anti-Müllerian hormone &amp;lt;/b&amp;gt; (AMH) is found to be elevated in patients with PCOS &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24821925 &amp;lt;/ref&amp;gt;, giving rise to its potential clinical implication in diagnosing PCOS. AMH is exclusively produced in ovarian follicles, with individual AMH concentration reflecting the quantity of remaining primordial follicles and measure of ovarian reserve. &lt;br /&gt;
&lt;br /&gt;
===Gynecologic ultrasonography===&lt;br /&gt;
Gynecologic ultrasonography is a pelvic ultrasound, specifically to the female pelvic region, with regards to the uterus, ovaries and the fallopian tube. The examination can be performed by transabdominal ultrasonography, with a full bladder, or transvaginal ultrasonography with a vaginal transducer. Typically transvaginal imaging shows a better and clearer image than transabdominal ultrasonography, as it uses higher frequency imaging, but is limited to areas it can reach. In the case of PCOS, both techniques can provide an image of the ovaries. Studies suggest that if more than 25 follicles are seen in an ovary, predominantly in the periphery, in women between 18-35 years, it is described to have a polycystic ovarian morphology. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24345633 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Magnetic Resonance Imaging===&lt;br /&gt;
Ovaries can also be seen on MRIs. On MRIs, PCOS is characterized by numberous peripheral cysts where the ovaries affected to be slightly larger than normal. Although MRI is seen to be effective in ovarian imaging, the finding of peripheral ovarian cysts in MRIsmay not be PCOS specific. &amp;lt;ref&amp;gt;  http://www.ncbi.nlm.nih.gov/pubmed/8888256 &amp;lt;/ref&amp;gt; But studies have seen that MR imaging in adolescence uncover distinct differences between young patients with and without PCOS &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/23292744 &amp;lt;/ref&amp;gt;, with also great diagnostic sensitivity with patients between the age of 21-30 &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/19241321 &amp;lt;/ref&amp;gt;, providing assistance of imagery in patients whom may be opposed to transvaginal ultrasounds.&lt;br /&gt;
&lt;br /&gt;
=Prevention=&lt;br /&gt;
&lt;br /&gt;
==Impact of physical activity on ovarian reserve markers in normal, overweight and obese reproductive age women==&lt;br /&gt;
&amp;lt;pubmed&amp;gt;25509968&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study focuses on the effect of physical activity on fertility in three groups of women at reproductive age; normal, overweight and obese. The results from the study suggest that there was a marked improvement in fertility as shown by the ovarian reserve markers for all 3 groups, however it was most significant in the overweight and obese groups. This study is relevant to our project as it gives an insight into the preventative measures that can be taken for infertility. &lt;br /&gt;
&lt;br /&gt;
==Risk factors of polycystic ovarian syndrome among Li People==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;26276294&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study examined the risk factors entailed in Polycystic Ovarian Syndrdome (PCOS) amoung Li people. Using the method of a case control study, questionnaires were given to female Li people with and without PCOS. Analysis of the questionnaires showed that family history of diabetes, family history of infertility, bad mood, lack of physical exercise are all high risk factors of PCOS. As a result, management of these risk factors can be taken into consideration when preventing infertility through PCOS.&lt;br /&gt;
&lt;br /&gt;
==Vitamin D and female fertility==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;24717915&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article is a review focusing on research regarding Vitamin D and fertility over the past year. The review found that the levels of Vitamin D is crucial for women undergoing in-vitro fertilisation. It  was also found that Vitamin D was beneficial for women with PCOS and carried a protective effect against endometriosis. These observations suggest that having sufficient Vitamin D in your body can be preventative for problems associated with fertility.&lt;br /&gt;

| '''CURRENT TREATMENT'''&lt;br /&gt;
| '''DISADVANTAGES'''&lt;br /&gt;
|-&lt;br /&gt;
| General Practitioners tend to prescribe oral anti-oestrogens, most commonly the contraceptive pill, to restore ovulation.&lt;br /&gt;
| This method only has a 50% success rate in PCOS patients. It does not directly increase fertility rates, but restores the menstrual cycle.&lt;br /&gt;
 &lt;br /&gt;
|-bgcolor=&amp;quot;FAF5FF&amp;quot;&lt;br /&gt;
| Lifestyle changes are highly encouraged by medical practitioners. Diet and exercise regimes can be designed with a dietitian or nutritionist. &lt;br /&gt;
| Exercise and diet plans do not directly increase fertility. They are designed to enhance weight loss, which in some patients can encourage normal hormone levels from the pituitary and thyroid. &lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| Clomiphene citrate administration (generally in pill form, as prescribed by a GP). Such pills stimulate the pituitary gland to release GnRH to simulate ovulation (with a 72% success rate in the ___ trial). &lt;br /&gt;
| Clomiphene can cause multiple side effects, most notably abnormal uterine bleeding and pelvic pain to due enlargement of the ovaries. &lt;br /&gt;
&lt;br /&gt;
Thus, it cannot be as frequently prescribed as the contraceptive pill, and careful patient monitoring is imperative. &lt;br /&gt;
&lt;br /&gt;
|-bgcolor=&amp;quot;FAF5FF&amp;quot;&lt;br /&gt;
| Higher fertility rates are observed in treatments combining clomiphene citrate and metformin (79% success).&lt;br /&gt;
| Similar disadvantages as clomiphene, above.&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
===New Trials===&lt;br /&gt;
&lt;br /&gt;
Some studies have found that regular Selenium supplements can encourage fertility among PCOS patients. The program, which is still in its early trial period, requires women to consume selenium tablets for 8 weeks. This study has found a significant decrease in dehydroepiandrosterone (DHEA) levels in patients, thus reducing excessive hair growth associated with PCOS. A direct link to increased fertility is yet to be established, and thus further testing is required.&lt;br /&gt;

=Female Infertility=&lt;br /&gt;
&lt;br /&gt;
[[File:Prevalence of Primary Infertility in 2010.jpeg|400px|thumb|right|Prevalence of Primary Infertility in 2010]]&lt;br /&gt;
&lt;br /&gt;
Female Infertility refers to the failure to conceive after one year of regular unprotected intercourse in females &amp;lt;ref name=one&amp;gt;&amp;lt;pubmed&amp;gt;26150870&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. In 2010, infertility affected 48.5 million couples world wide and the areas of highest prevalence included North Africa and Middle East, South Asia, Central/Eastern Europe and Central Asia and Sub-Saharan Africa &amp;lt;ref name=two&amp;gt;&amp;lt;pubmed&amp;gt;23271957&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. As there are several causes of female infertility, we will be focusing on infertility that is caused by '''Polycystic Ovarian Syndrome''' (PCOS), the most common cause of infertility that is medically treatable &amp;lt;ref name=one/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Polycystic Ovarian Syndrome==&lt;br /&gt;
Polycystic Ovarian Syndrome (PCOS) is a common endocrine disorder, affecting up to 20% of reproductive aged women [3] It is the most common cause of anovulatory infertility [1] which refers to infertility caused by the the absence of ovulation.&lt;br /&gt;
&lt;br /&gt;
=Causes=&lt;br /&gt;
&lt;br /&gt;
PCOS is a disorder of heterogeneous origin with unknown aetiology &amp;lt;ref name=four&amp;gt;&amp;lt;pubmed&amp;gt;21896560&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Studies have shown that both genetic and environmental factors contribute to the development of PCOS in women however there is limited research into the actual interactions between these two factors &amp;lt;ref name=un&amp;gt;&amp;lt;pubmed&amp;gt;17185788&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Genetic Factors===&lt;br /&gt;
&lt;br /&gt;
Despite the lack of information regarding its aetiology, there is increasing evidence for a genetic involvement in the endocrine disorder. Studies have shown that genes play an important role in contributing towards the clinical and biochemical features of the disease &amp;lt;ref name=four/&amp;gt;. This evidence includes the family clustering of cases, greater unanimity between monozygotic twins than heterozygotic twins and the ability to inherit endocrine and  metabolic features of PCOS &amp;lt;ref name=four/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
In one study, 115 sisters of women with PCOS were examined and results showed that half of these sisters had high testosterone levels, suggesting that hyperandrogenemia is a common trait with a dominant pattern of inheritance. These results strongly supported the idea of the familial clustering of biochemical features such as hyperandrogenism in first degree relatives &amp;lt;ref name=deux&amp;gt;&amp;lt;pubmed&amp;gt;9843997&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
Several genes have been considered to play an important role in the development of PCOS such as CYP11A, the insulin gene, the follistatin gene and a region near the insulin receptor gene. Yet, the evidence supporting most of these genes has been refuted by larger studies, except for the region near the insulin receptor gene &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
There has been strong evidence linking the gene CYP11a with hyperandrogenism in women with PCOS. &amp;lt;ref name=cinq&amp;gt;&amp;lt;pubmed&amp;gt;9147642&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; While it doesn't isolate this gene as the sole cause of PCOS, variation of the genotype at this locus contributes to production of excess androgen &amp;lt;ref name=h4&amp;gt;&amp;lt;pubmed&amp;gt;7962289&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Studies have also shown that there is strong evidence for linkage between the alleles at the Variable Number Tandem Repeats (VNTR) which is situated 5' to the insulin gene and PCOS. The data from the study suggests that it is a very susceptible region in PCOS and also may play a role in the development of hyperinsulinaemia &amp;lt;ref name=trois&amp;gt;&amp;lt;pubmed&amp;gt;9455828&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
===Environmental Factors===&lt;br /&gt;
The prevalence of PCOS in populations where there has been a constant gene pool indicates that environmental factors play a significant role in the aetiology of PCOS.&lt;br /&gt;
&lt;br /&gt;
===Obesity and Diet===&lt;br /&gt;
Obesity is the major environmental factor driving the development of PCOS in susceptible individuals. The rising rates of PCOS have been paralleled by the widespread emergence of obesity and type 2 diabetes which are prevalent in developed countries. The risk of developing PCOS from obesity is compounded by  poor dietary choices and lack of physical activity which has begun to characterise the lifestyle in developed countries &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Medication===&lt;br /&gt;
Studies have shown that valproic acid in medication used to treat epilepsy and bipolar disorders contributes to the development of PCOS. Women with these disorders  may develop the typical features of PCOS such as polycystic ovaries, anovulation, hyperandrogenism and obesity &amp;lt;ref name=quartre&amp;gt;&amp;lt;pubmed&amp;gt;8413434&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Recent studies also suggest that the weight gain from medication is significant as it can lead to the development of PCOS &amp;lt;ref name=deux/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=Pathogenesis=&lt;br /&gt;
&lt;br /&gt;
The pathogenesis of polycystic ovarian syndrome is poorly understood, however it is believed that insulin resistance and excess androgens such as testosterone play a fundamental role.&lt;br /&gt;
Underlying factors such as obesity and genetic predispositions likely contribute to the onset of polycystic ovarian syndrome through the development of a combination of hyperinsulinemia and hyperandrogenemia.&amp;lt;ref name=eleven&amp;gt;&amp;lt;pubmed&amp;gt;PMC4556908&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
===Hyperinsulinemia===&lt;br /&gt;
&lt;br /&gt;
Hyperinsulinemia is a term that defines the presence of excessive amounts of insulin in the blood relative to the amount of glucose. &amp;lt;ref name=fourteen&amp;gt;&amp;lt;pubmed&amp;gt;PMC4114053&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; This phenomenon is typically associated with obesity and excess adipose tissue, both of which are associated with insulin resistance. In order to overcome this resistance, insulin secretion is increased in an attempt to normalise blood glucose levels, thereby leading to hyperinsulineamia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC2782313&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; Excessive levels of insulin typically cause disruption to the hypothalamus-hypophysis-ovary axis whilst insulin resistance in ovarian tissues leads to decreased metabolic signalling. However, steroidogenic activity is largely unaffected by the impaired metabolic signalling, thereby paving the way androgens to become more effect and paving the way towards hyperandrogenemia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
[[File:Patholophysiology of Polycystic Ovarian Syndrome.jpg|500px|thumb|left|The impact of hyperinsulinemia and hyperandrogenemia on the development of polycystic ovarian syndrome]]&lt;br /&gt;
&lt;br /&gt;
==Hyperandrogenemia==&lt;br /&gt;
&lt;br /&gt;
Hyperandrogenemia is a hallmark of the development of polycystic ovarian syndrome, with 80% of women presenting with excess androgen also having polycystic ovaries.&amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; The disruption of the hypothalamus hypophysis ovary axis as a result of hyperinsulinemia increases the release of GnRH and LH, leading to increased androgen production in the ovarian theca cells. Hyperandrogenemia decreases the feedback sensitivity of both estradiol and progesterone within gonadotropic hypothalmic cells. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; A deficiency of FSH is observed and correlates with the increased secretion of GnRH and LH. As a result of this deficiency, graunlosa  cell aromatisation to oestrogens as well as follicle maturation and ovulation will be drastically impaired.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3453528&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
As a consequence of the impairment of follicle maturation, small antral follicles will accumulate within the periphery of the ovary and develop a cystic morphology. Ovulation will be unable to occur due to the absence of mature follicles, culminating in infertility.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4562327&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Hyperandrogenism==&lt;br /&gt;
&lt;br /&gt;
===Animal Models===&lt;br /&gt;
&lt;br /&gt;
Studies conducted on female rhesus monkeys have supported evidence for the foetal origins of the clinical features of PCOS &amp;lt;ref name=h1&amp;gt;&amp;lt;pubmed&amp;gt;18406243&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.  It has been shown that in human females, an excess of androgen exposure at any stage from the development of the ovaries to the onset of puberty manifests as characteristic features of PCOS, such as resistance to insulin and Luteinising Hormone (LH) hypersecretion. After exposure to levels of testosterone matching those of fetal males, in utero, female rhesus monkeys were found to display the clinical and biochemical features typical of PCOS such as hypersecretion of LH and abnormal insulin action. These results correlated to those of similar studies conducted on sheep, where the pregnant ewe was exposed to excessive levels of testosterone and LH secretion and abnormality in ovarian cycles were again prominent features &amp;lt;ref name=sheep&amp;gt;Padmanabhan V, Evans NP, Taylor JA, Robinson JE1997 '''Prenatal exposure to  androgens  leads  to  the  development  of  cystic  ovaries  in  the  sheep'''. Biol Reprod 56:194&amp;lt;/ref&amp;gt;. While these studies indicate that similar biochemical and clinical manifestations in humans originate from excess androgen exposure of the female fetus, it must be noted that it is very unlikely for any excess androgen production to be passed across the placenta from the mother to her daughter. This is because mechanisms such as androgen binding proteins and placental metabolism of androgen prevent excess androgen entering the circulation of the fetus &amp;lt;ref name=h2&amp;gt;&amp;lt;pubmed&amp;gt;12098657&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
===Cell Culture Models===&lt;br /&gt;
&lt;br /&gt;
While studies have shown that the adrenal could be a source of excess androgen such as the adrenal &amp;lt;ref name=h3&amp;gt;&amp;lt;pubmed&amp;gt;7962325&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;, they were followed by various studies using cell culture models which demonstrated that the ovary was the major source of excess androgen &amp;lt;ref name=h4/&amp;gt; &amp;lt;ref name=h5&amp;gt;&amp;lt;pubmed&amp;gt;9302378&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. ''In vitro'' studies have shown that the production of steroids is abnormal in theca cells &amp;lt;ref name=h3/&amp;gt;. In women affected by PCOS, stimulation by human chorionic gonadotrophin (hCG) is followed by an increase in thecal steroid production after suppression of LH by a GnRH analogue &amp;lt;ref name=h5/&amp;gt;. Theca cells cultured from polycystic ovaries produce 20 times as much androstenedione as those from normal ovaries &amp;lt;ref name=h4/&amp;gt; with increased expression of mRNA for enzymes responsible for making steroids also reported in following studies. &amp;lt;ref name=h6&amp;gt;&amp;lt;pubmed&amp;gt;10852468&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; These results have prompted many studies on genes encoding these steroidogeneic enzymes.&lt;br /&gt;
&lt;br /&gt;

===The Genetics of Infertility: Current Status of the Field===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3885174&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article attempted to determine the role that genetics plays in female infertility. It was noted that several prominent causes of female infertility such as Galactosemia and Primary Ovarian Failure (POF) were associated with specific genes, with the GALT gene contributing to the former condition and the FMR1 gene contributing to the latter.&lt;br /&gt;
&lt;br /&gt;
===Causes of Sterility in Bosnia-Herzegovina Population===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC4499307&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
The study conducted as laid out in this article examined the causes of female sterility in the Bosnia-Herzegovina population. Married participants were arranged into various groups based upon their age. The experiment came to the conclusion that in approximately 42% of infertile married couples, female sterility was the primary cause. The two primary causes of female infertility were tubal deficiencies (31% of cases) and Diminished Ovarian Reserves (38% of cases)&lt;br /&gt;
&lt;br /&gt;
===Epidemiology, diagnosis, and management of polycystic ovary syndrome===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This research article examines the causes of polycystic ovary syndrome (POS), a common cause of infertility in women. The article concluded that 50-70% of women suffer from insulin resistance secondary to Type 2 Diabetes and in many cases obseity, which may contribute partially to POS. Furthermore, 85-90% of women with oligomenorrhea also had POS, suggesting that it is an underlying cause. However, the exact pathophysiology of POS was not determined.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Signs and Symptoms=&lt;br /&gt;
&lt;br /&gt;
The symptoms of PCOS are different for each women. The three cardinal signs of PCOS are hyperandrogenism, polycystic ovaries and ovarian dysfunction &amp;lt;ref name=sign1&amp;gt;&amp;lt;pubmed&amp;gt;14688154&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Common clinical symptoms include &amp;lt;ref&amp;gt; Women's Heath, U.S. Department of Health and Human Services ,[ http://www.womenshealth.gov/publications/our-publications/fact-sheet/polycystic-ovary-syndrome.html#d ], 'Polycystic ovary syndrome (PCOS) fact sheet'&amp;lt;/ref&amp;gt; ;&lt;br /&gt;

* '''Infertility'''- Due to anovulation caused by PCOS. &lt;br /&gt;
* '''Irregular Menstrual Cycles'''&lt;br /&gt;
* '''Hirsutism'''&lt;br /&gt;

* '''Obesity'''&lt;br /&gt;
* '''Male Pattern Baldness '''&lt;br /&gt;
* '''Skin Tags'''&lt;br /&gt;
* '''Pelvic Pain'''&lt;br /&gt;
&lt;br /&gt;
Along with obesity, PCOS is also associated with other metabolic issues such as insulin resistance, hyperinsulinemia and type 2 diabetes mellitus. It has also been associated with cardiovascular problems and cancers of the breast and endometrium &amp;lt;ref name=sign3&amp;gt;&amp;lt;pubmed&amp;gt;PMC4341818&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=Diagnosis=&lt;br /&gt;
&lt;br /&gt;
A major diagnostic tool for PCOS is a pelvic ultrasound, but PCOS diagnosis cannot be completely dependent on just pelvic ultrasounds. A patient with PCOS may not necessarily have polycystic ovaries, and those with ovarian cysts may not necessarily have PCOS. A range of diagnostic assessments and associated symptoms have to be thoroughly investigated.&lt;br /&gt;
&lt;br /&gt;
===Medical history and examination===&lt;br /&gt;
Clinical questions are asked or filled out in the form of a questionnaire to assess and assist in the diagnosis of PCOS. Studies show that those with a history:&lt;br /&gt;
*infrequent and irregular menstruation&lt;br /&gt;
*hirsutism (related to high levels of androgens in the blood – hyperandrogenism)&lt;br /&gt;
*obesity&lt;br /&gt;
*acne production &lt;br /&gt;
are at a higher predictive risk of PCOS. But questions regarding failed pregnancy attempts and history of nipple discharge proved no correlation in diagnosing PCOS. &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/17872783 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Blood Test===&lt;br /&gt;
A patient with elevated levels of androgens, a medical condition called &amp;lt;b&amp;gt;hyperandrogenism &amp;lt;/b&amp;gt;, is very highly likely to have PCOS. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/20591140 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&amp;lt;b&amp;gt; Androgens &amp;lt;/b&amp;gt; , such as testosterone, and &amp;lt;b&amp;gt;free androgen index (FAI) &amp;lt;/b&amp;gt; are the two tests best used in diagnosing hyperandrogenism.&lt;br /&gt;
Androgen excess in PCOS is a result from increased synthesis and release of ovarian androgens. &amp;lt;b&amp;gt;Dehydroepiandrosterone sulfate &amp;lt;/b&amp;gt; (DHEA-S) levels are used as a biomarker for testing androgen levels, as it is made exclusively by the adrenal glands. DHEA-S levels of above 1890 micromol/L is extremely suggestive of hyperandrogenism. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/18844715 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&amp;lt;b&amp;gt;Free androgen index (FAI) &amp;lt;/b&amp;gt; is the ratio of total testosterone measurement to levels of &amp;lt;b&amp;gt; sex hormone-binding globulin &amp;lt;/b&amp;gt; (SHBG). Those with PCOS will have high FAI, as this indicates a high ration of free testosterone in the body.&lt;br /&gt;
Other blood tests are also done to help exclude other predisposing factors such as levels of &amp;lt;b&amp;gt; Thyroid Stimulating Hormone &amp;lt;/b&amp;gt; (LSH) and &amp;lt;b&amp;gt; Follicle-stimulating hormone &amp;lt;/b&amp;gt; (FSH). An elevated ratio of LSH to FSH, of above 2:1 &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/14737959 &amp;lt;/ref&amp;gt;, indicates a possibility, but not definitively, of PCOS.&lt;br /&gt;
The effect of &amp;lt;b&amp;gt; insulin &amp;lt;/b&amp;gt; on blood can also be tested for insulin resistance. Insulin resistance enhances androgen production and increases free androgen levels by reducing SHBG. This can used as an indication marker for the possibility of PCOS&lt;br /&gt;
A study in 2014 showed that &amp;lt;b&amp;gt; Anti-Müllerian hormone &amp;lt;/b&amp;gt; (AMH) is found to be elevated in patients with PCOS &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24821925 &amp;lt;/ref&amp;gt;, giving rise to its potential clinical implication in diagnosing PCOS. AMH is exclusively produced in ovarian follicles, with individual AMH concentration reflecting the quantity of remaining primordial follicles and measure of ovarian reserve. &lt;br /&gt;
&lt;br /&gt;
===Gynecologic ultrasonography===&lt;br /&gt;
Gynecologic ultrasonography is a pelvic ultrasound, specifically to the female pelvic region, with regards to the uterus, ovaries and the fallopian tube. The examination can be performed by transabdominal ultrasonography, with a full bladder, or transvaginal ultrasonography with a vaginal transducer. Typically transvaginal imaging shows a better and clearer image than transabdominal ultrasonography, as it uses higher frequency imaging, but is limited to areas it can reach. In the case of PCOS, both techniques can provide an image of the ovaries. Studies suggest that if more than 25 follicles are seen in an ovary, predominantly in the periphery, in women between 18-35 years, it is described to have a polycystic ovarian morphology. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24345633 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Magnetic Resonance Imaging===&lt;br /&gt;
Ovaries can also be seen on MRIs. On MRIs, PCOS is characterized by numberous peripheral cysts where the ovaries affected to be slightly larger than normal. Although MRI is seen to be effective in ovarian imaging, the finding of peripheral ovarian cysts in MRIsmay not be PCOS specific. &amp;lt;ref&amp;gt;  http://www.ncbi.nlm.nih.gov/pubmed/8888256 &amp;lt;/ref&amp;gt; But studies have seen that MR imaging in adolescence uncover distinct differences between young patients with and without PCOS &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/23292744 &amp;lt;/ref&amp;gt;, with also great diagnostic sensitivity with patients between the age of 21-30 &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/19241321 &amp;lt;/ref&amp;gt;, providing assistance of imagery in patients whom may be opposed to transvaginal ultrasounds.&lt;br /&gt;
&lt;br /&gt;
=Prevention=&lt;br /&gt;
&lt;br /&gt;
==Impact of physical activity on ovarian reserve markers in normal, overweight and obese reproductive age women==&lt;br /&gt;
&amp;lt;pubmed&amp;gt;25509968&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study focuses on the effect of physical activity on fertility in three groups of women at reproductive age; normal, overweight and obese. The results from the study suggest that there was a marked improvement in fertility as shown by the ovarian reserve markers for all 3 groups, however it was most significant in the overweight and obese groups. This study is relevant to our project as it gives an insight into the preventative measures that can be taken for infertility. &lt;br /&gt;
&lt;br /&gt;
==Risk factors of polycystic ovarian syndrome among Li People==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;26276294&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study examined the risk factors entailed in Polycystic Ovarian Syndrdome (PCOS) amoung Li people. Using the method of a case control study, questionnaires were given to female Li people with and without PCOS. Analysis of the questionnaires showed that family history of diabetes, family history of infertility, bad mood, lack of physical exercise are all high risk factors of PCOS. As a result, management of these risk factors can be taken into consideration when preventing infertility through PCOS.&lt;br /&gt;
&lt;br /&gt;
==Vitamin D and female fertility==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;24717915&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article is a review focusing on research regarding Vitamin D and fertility over the past year. The review found that the levels of Vitamin D is crucial for women undergoing in-vitro fertilisation. It  was also found that Vitamin D was beneficial for women with PCOS and carried a protective effect against endometriosis. These observations suggest that having sufficient Vitamin D in your body can be preventative for problems associated with fertility.&lt;br /&gt;

| '''DISADVANTAGES'''&lt;br /&gt;
|-&lt;br /&gt;
| General Practitioners tend to prescribe oral anti-oestrogens, most commonly the contraceptive pill, to restore ovulation.&lt;br /&gt;
| This method only has a 50% success rate in PCOS patients. It does not directly increase fertility rates, but restores the menstrual cycle.&lt;br /&gt;
 &lt;br /&gt;
|-bgcolor=&amp;quot;FAF5FF&amp;quot;&lt;br /&gt;
| Lifestyle changes are highly encouraged by medical practitioners. Diet and exercise regimes can be designed with a dietitian or nutritionist. &lt;br /&gt;
| Exercise and diet plans do not directly increase fertility. They are designed to enhance weight loss, which in some patients can encourage normal hormone levels from the pituitary and thyroid. &lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| Clomiphene citrate administration (generally in pill form, as prescribed by a GP). Such pills stimulate the pituitary gland to release GnRH to simulate ovulation (with a 72% success rate in the ___ trial). &lt;br /&gt;
| Clomiphene can cause multiple side effects, most notably abnormal uterine bleeding and pelvic pain to due enlargement of the ovaries. &lt;br /&gt;
&lt;br /&gt;
Thus, it cannot be as frequently prescribed as the contraceptive pill, and careful patient monitoring is imperative. &lt;br /&gt;
&lt;br /&gt;
|-bgcolor=&amp;quot;FAF5FF&amp;quot;&lt;br /&gt;
| Higher fertility rates are observed in treatments combining clomiphene citrate and metformin (79% success).&lt;br /&gt;
| Similar disadvantages as clomiphene, above.&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
===New Trials===&lt;br /&gt;
&lt;br /&gt;
Some studies have found that regular Selenium supplements can encourage fertility among PCOS patients. The program, which is still in its early trial period, requires women to consume selenium tablets for 8 weeks. This study has found a significant decrease in dehydroepiandrosterone (DHEA) levels in patients, thus reducing excessive hair growth associated with PCOS. A direct link to increased fertility is yet to be established, and thus further testing is required.&lt;br /&gt;

=Female Infertility=&lt;br /&gt;
&lt;br /&gt;
[[File:Prevalence of Primary Infertility in 2010.jpeg|400px|thumb|right|Prevalence of Primary Infertility in 2010]]&lt;br /&gt;
&lt;br /&gt;
Female Infertility refers to the failure to conceive after one year of regular unprotected intercourse in females &amp;lt;ref name=one&amp;gt;&amp;lt;pubmed&amp;gt;26150870&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. In 2010, infertility affected 48.5 million couples world wide and the areas of highest prevalence included North Africa and Middle East, South Asia, Central/Eastern Europe and Central Asia and Sub-Saharan Africa &amp;lt;ref name=two&amp;gt;&amp;lt;pubmed&amp;gt;23271957&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. As there are several causes of female infertility, we will be focusing on infertility that is caused by '''Polycystic Ovarian Syndrome''' (PCOS), the most common cause of infertility that is medically treatable &amp;lt;ref name=one/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Polycystic Ovarian Syndrome==&lt;br /&gt;
Polycystic Ovarian Syndrome (PCOS) is a common endocrine disorder, affecting up to 20% of reproductive aged women [3] It is the most common cause of anovulatory infertility [1] which refers to infertility caused by the the absence of ovulation.&lt;br /&gt;
&lt;br /&gt;
=Causes=&lt;br /&gt;
&lt;br /&gt;
PCOS is a disorder of heterogeneous origin with unknown aetiology &amp;lt;ref name=four&amp;gt;&amp;lt;pubmed&amp;gt;21896560&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Studies have shown that both genetic and environmental factors contribute to the development of PCOS in women however there is limited research into the actual interactions between these two factors &amp;lt;ref name=un&amp;gt;&amp;lt;pubmed&amp;gt;17185788&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Genetic Factors===&lt;br /&gt;
&lt;br /&gt;
Despite the lack of information regarding its aetiology, there is increasing evidence for a genetic involvement in the endocrine disorder. Studies have shown that genes play an important role in contributing towards the clinical and biochemical features of the disease &amp;lt;ref name=four/&amp;gt;. This evidence includes the family clustering of cases, greater unanimity between monozygotic twins than heterozygotic twins and the ability to inherit endocrine and  metabolic features of PCOS &amp;lt;ref name=four/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
In one study, 115 sisters of women with PCOS were examined and results showed that half of these sisters had high testosterone levels, suggesting that hyperandrogenemia is a common trait with a dominant pattern of inheritance. These results strongly supported the idea of the familial clustering of biochemical features such as hyperandrogenism in first degree relatives &amp;lt;ref name=deux&amp;gt;&amp;lt;pubmed&amp;gt;9843997&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
Several genes have been considered to play an important role in the development of PCOS such as CYP11A, the insulin gene, the follistatin gene and a region near the insulin receptor gene. Yet, the evidence supporting most of these genes has been refuted by larger studies, except for the region near the insulin receptor gene &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
There has been strong evidence linking the gene CYP11a with hyperandrogenism in women with PCOS. &amp;lt;ref name=cinq&amp;gt;&amp;lt;pubmed&amp;gt;9147642&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; While it doesn't isolate this gene as the sole cause of PCOS, variation of the genotype at this locus contributes to production of excess androgen &amp;lt;ref name=h4&amp;gt;&amp;lt;pubmed&amp;gt;7962289&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Studies have also shown that there is strong evidence for linkage between the alleles at the Variable Number Tandem Repeats (VNTR) which is situated 5' to the insulin gene and PCOS. The data from the study suggests that it is a very susceptible region in PCOS and also may play a role in the development of hyperinsulinaemia &amp;lt;ref name=trois&amp;gt;&amp;lt;pubmed&amp;gt;9455828&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
===Environmental Factors===&lt;br /&gt;
The prevalence of PCOS in populations where there has been a constant gene pool indicates that environmental factors play a significant role in the aetiology of PCOS.&lt;br /&gt;
&lt;br /&gt;
===Obesity and Diet===&lt;br /&gt;
Obesity is the major environmental factor driving the development of PCOS in susceptible individuals. The rising rates of PCOS have been paralleled by the widespread emergence of obesity and type 2 diabetes which are prevalent in developed countries. The risk of developing PCOS from obesity is compounded by  poor dietary choices and lack of physical activity which has begun to characterise the lifestyle in developed countries &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Medication===&lt;br /&gt;
Studies have shown that valproic acid in medication used to treat epilepsy and bipolar disorders contributes to the development of PCOS. Women with these disorders  may develop the typical features of PCOS such as polycystic ovaries, anovulation, hyperandrogenism and obesity &amp;lt;ref name=quartre&amp;gt;&amp;lt;pubmed&amp;gt;8413434&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Recent studies also suggest that the weight gain from medication is significant as it can lead to the development of PCOS &amp;lt;ref name=deux/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=Pathogenesis=&lt;br /&gt;
&lt;br /&gt;
The pathogenesis of polycystic ovarian syndrome is poorly understood, however it is believed that insulin resistance and excess androgens such as testosterone play a fundamental role.&lt;br /&gt;
Underlying factors such as obesity and genetic predispositions likely contribute to the onset of polycystic ovarian syndrome through the development of a combination of hyperinsulinemia and hyperandrogenemia.&amp;lt;ref name=eleven&amp;gt;&amp;lt;pubmed&amp;gt;PMC4556908&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
==Hyperinsulinemia==&lt;br /&gt;
&lt;br /&gt;
Hyperinsulinemia is a term that defines the presence of excessive amounts of insulin in the blood relative to the amount of glucose. &amp;lt;ref name=fourteen&amp;gt;&amp;lt;pubmed&amp;gt;PMC4114053&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; This phenomenon is typically associated with obesity and excess adipose tissue, both of which are associated with insulin resistance. In order to overcome this resistance, insulin secretion is increased in an attempt to normalise blood glucose levels, thereby leading to hyperinsulineamia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC2782313&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; Excessive levels of insulin typically cause disruption to the hypothalamus-hypophysis-ovary axis whilst insulin resistance in ovarian tissues leads to decreased metabolic signalling. However, steroidogenic activity is largely unaffected by the impaired metabolic signalling, thereby paving the way androgens to become more effect and paving the way towards hyperandrogenemia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
[[File:Patholophysiology of Polycystic Ovarian Syndrome.jpg|500px|thumb|left|The impact of hyperinsulinemia and hyperandrogenemia on the development of polycystic ovarian syndrome]]&lt;br /&gt;
&lt;br /&gt;
==Hyperandrogenemia==&lt;br /&gt;
&lt;br /&gt;
Hyperandrogenemia is a hallmark of the development of polycystic ovarian syndrome, with 80% of women presenting with excess androgen also having polycystic ovaries.&amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; The disruption of the hypothalamus hypophysis ovary axis as a result of hyperinsulinemia increases the release of GnRH and LH, leading to increased androgen production in the ovarian theca cells. Hyperandrogenemia decreases the feedback sensitivity of both estradiol and progesterone within gonadotropic hypothalmic cells. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; A deficiency of FSH is observed and correlates with the increased secretion of GnRH and LH. As a result of this deficiency, graunlosa  cell aromatisation to oestrogens as well as follicle maturation and ovulation will be drastically impaired.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3453528&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
As a consequence of the impairment of follicle maturation, small antral follicles will accumulate within the periphery of the ovary and develop a cystic morphology. Ovulation will be unable to occur due to the absence of mature follicles, culminating in infertility.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4562327&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Hyperandrogenism==&lt;br /&gt;
&lt;br /&gt;
===Animal Models===&lt;br /&gt;
&lt;br /&gt;
Studies conducted on female rhesus monkeys have supported evidence for the foetal origins of the clinical features of PCOS &amp;lt;ref name=h1&amp;gt;&amp;lt;pubmed&amp;gt;18406243&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.  It has been shown that in human females, an excess of androgen exposure at any stage from the development of the ovaries to the onset of puberty manifests as characteristic features of PCOS, such as resistance to insulin and Luteinising Hormone (LH) hypersecretion. After exposure to levels of testosterone matching those of fetal males, in utero, female rhesus monkeys were found to display the clinical and biochemical features typical of PCOS such as hypersecretion of LH and abnormal insulin action. These results correlated to those of similar studies conducted on sheep, where the pregnant ewe was exposed to excessive levels of testosterone and LH secretion and abnormality in ovarian cycles were again prominent features &amp;lt;ref name=sheep&amp;gt;Padmanabhan V, Evans NP, Taylor JA, Robinson JE1997 '''Prenatal exposure to  androgens  leads  to  the  development  of  cystic  ovaries  in  the  sheep'''. Biol Reprod 56:194&amp;lt;/ref&amp;gt;. While these studies indicate that similar biochemical and clinical manifestations in humans originate from excess androgen exposure of the female fetus, it must be noted that it is very unlikely for any excess androgen production to be passed across the placenta from the mother to her daughter. This is because mechanisms such as androgen binding proteins and placental metabolism of androgen prevent excess androgen entering the circulation of the fetus &amp;lt;ref name=h2&amp;gt;&amp;lt;pubmed&amp;gt;12098657&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
===Cell Culture Models===&lt;br /&gt;
&lt;br /&gt;
While studies have shown that the adrenal could be a source of excess androgen such as the adrenal &amp;lt;ref name=h3&amp;gt;&amp;lt;pubmed&amp;gt;7962325&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;, they were followed by various studies using cell culture models which demonstrated that the ovary was the major source of excess androgen &amp;lt;ref name=h4/&amp;gt; &amp;lt;ref name=h5&amp;gt;&amp;lt;pubmed&amp;gt;9302378&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. ''In vitro'' studies have shown that the production of steroids is abnormal in theca cells &amp;lt;ref name=h3/&amp;gt;. In women affected by PCOS, stimulation by human chorionic gonadotrophin (hCG) is followed by an increase in thecal steroid production after suppression of LH by a GnRH analogue &amp;lt;ref name=h5/&amp;gt;. Theca cells cultured from polycystic ovaries produce 20 times as much androstenedione as those from normal ovaries &amp;lt;ref name=h4/&amp;gt; with increased expression of mRNA for enzymes responsible for making steroids also reported in following studies. &amp;lt;ref name=h6&amp;gt;&amp;lt;pubmed&amp;gt;10852468&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; These results have prompted many studies on genes encoding these steroidogeneic enzymes.&lt;br /&gt;
&lt;br /&gt;

===The Genetics of Infertility: Current Status of the Field===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3885174&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article attempted to determine the role that genetics plays in female infertility. It was noted that several prominent causes of female infertility such as Galactosemia and Primary Ovarian Failure (POF) were associated with specific genes, with the GALT gene contributing to the former condition and the FMR1 gene contributing to the latter.&lt;br /&gt;
&lt;br /&gt;
===Causes of Sterility in Bosnia-Herzegovina Population===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC4499307&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
The study conducted as laid out in this article examined the causes of female sterility in the Bosnia-Herzegovina population. Married participants were arranged into various groups based upon their age. The experiment came to the conclusion that in approximately 42% of infertile married couples, female sterility was the primary cause. The two primary causes of female infertility were tubal deficiencies (31% of cases) and Diminished Ovarian Reserves (38% of cases)&lt;br /&gt;
&lt;br /&gt;
===Epidemiology, diagnosis, and management of polycystic ovary syndrome===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This research article examines the causes of polycystic ovary syndrome (POS), a common cause of infertility in women. The article concluded that 50-70% of women suffer from insulin resistance secondary to Type 2 Diabetes and in many cases obseity, which may contribute partially to POS. Furthermore, 85-90% of women with oligomenorrhea also had POS, suggesting that it is an underlying cause. However, the exact pathophysiology of POS was not determined.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Signs and Symptoms=&lt;br /&gt;
&lt;br /&gt;
The symptoms of PCOS are different for each women. The three cardinal signs of PCOS are hyperandrogenism, polycystic ovaries and ovarian dysfunction &amp;lt;ref name=sign1&amp;gt;&amp;lt;pubmed&amp;gt;14688154&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Common clinical symptoms include &amp;lt;ref&amp;gt; Women's Heath, U.S. Department of Health and Human Services ,[ http://www.womenshealth.gov/publications/our-publications/fact-sheet/polycystic-ovary-syndrome.html#d ], 'Polycystic ovary syndrome (PCOS) fact sheet'&amp;lt;/ref&amp;gt; ;&lt;br /&gt;

&lt;br /&gt;
Along with obesity, PCOS is also associated with other metabolic issues such as insulin resistance, hyperinsulinemia and type 2 diabetes mellitus. It has also been associated with cardiovascular problems and cancers of the breast and endometrium &amp;lt;ref name=sign3&amp;gt;&amp;lt;pubmed&amp;gt;PMC4341818&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=Diagnosis=&lt;br /&gt;
&lt;br /&gt;
A major diagnostic tool for PCOS is a pelvic ultrasound, but PCOS diagnosis cannot be completely dependent on just pelvic ultrasounds. A patient with PCOS may not necessarily have polycystic ovaries, and those with ovarian cysts may not necessarily have PCOS. A range of diagnostic assessments and associated symptoms have to be thoroughly investigated.&lt;br /&gt;
&lt;br /&gt;
===Medical history and examination===&lt;br /&gt;
Clinical questions are asked or filled out in the form of a questionnaire to assess and assist in the diagnosis of PCOS. Studies show that those with a history:&lt;br /&gt;
*infrequent and irregular menstruation&lt;br /&gt;
*hirsutism (related to high levels of androgens in the blood – hyperandrogenism)&lt;br /&gt;
*obesity&lt;br /&gt;
*acne production &lt;br /&gt;
are at a higher predictive risk of PCOS. But questions regarding failed pregnancy attempts and history of nipple discharge proved no correlation in diagnosing PCOS. &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/17872783 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Blood Test===&lt;br /&gt;
A patient with elevated levels of androgens, a medical condition called &amp;lt;b&amp;gt;hyperandrogenism &amp;lt;/b&amp;gt;, is very highly likely to have PCOS. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/20591140 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&amp;lt;b&amp;gt; Androgens &amp;lt;/b&amp;gt; , such as testosterone, and &amp;lt;b&amp;gt;free androgen index (FAI) &amp;lt;/b&amp;gt; are the two tests best used in diagnosing hyperandrogenism.&lt;br /&gt;
Androgen excess in PCOS is a result from increased synthesis and release of ovarian androgens. &amp;lt;b&amp;gt;Dehydroepiandrosterone sulfate &amp;lt;/b&amp;gt; (DHEA-S) levels are used as a biomarker for testing androgen levels, as it is made exclusively by the adrenal glands. DHEA-S levels of above 1890 micromol/L is extremely suggestive of hyperandrogenism. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/18844715 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&amp;lt;b&amp;gt;Free androgen index (FAI) &amp;lt;/b&amp;gt; is the ratio of total testosterone measurement to levels of &amp;lt;b&amp;gt; sex hormone-binding globulin &amp;lt;/b&amp;gt; (SHBG). Those with PCOS will have high FAI, as this indicates a high ration of free testosterone in the body.&lt;br /&gt;
Other blood tests are also done to help exclude other predisposing factors such as levels of &amp;lt;b&amp;gt; Thyroid Stimulating Hormone &amp;lt;/b&amp;gt; (LSH) and &amp;lt;b&amp;gt; Follicle-stimulating hormone &amp;lt;/b&amp;gt; (FSH). An elevated ratio of LSH to FSH, of above 2:1 &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/14737959 &amp;lt;/ref&amp;gt;, indicates a possibility, but not definitively, of PCOS.&lt;br /&gt;
The effect of &amp;lt;b&amp;gt; insulin &amp;lt;/b&amp;gt; on blood can also be tested for insulin resistance. Insulin resistance enhances androgen production and increases free androgen levels by reducing SHBG. This can used as an indication marker for the possibility of PCOS&lt;br /&gt;
A study in 2014 showed that &amp;lt;b&amp;gt; Anti-Müllerian hormone &amp;lt;/b&amp;gt; (AMH) is found to be elevated in patients with PCOS &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24821925 &amp;lt;/ref&amp;gt;, giving rise to its potential clinical implication in diagnosing PCOS. AMH is exclusively produced in ovarian follicles, with individual AMH concentration reflecting the quantity of remaining primordial follicles and measure of ovarian reserve. &lt;br /&gt;
&lt;br /&gt;
===Gynecologic ultrasonography===&lt;br /&gt;
Gynecologic ultrasonography is a pelvic ultrasound, specifically to the female pelvic region, with regards to the uterus, ovaries and the fallopian tube. The examination can be performed by transabdominal ultrasonography, with a full bladder, or transvaginal ultrasonography with a vaginal transducer. Typically transvaginal imaging shows a better and clearer image than transabdominal ultrasonography, as it uses higher frequency imaging, but is limited to areas it can reach. In the case of PCOS, both techniques can provide an image of the ovaries. Studies suggest that if more than 25 follicles are seen in an ovary, predominantly in the periphery, in women between 18-35 years, it is described to have a polycystic ovarian morphology. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24345633 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Magnetic Resonance Imaging===&lt;br /&gt;
Ovaries can also be seen on MRIs. On MRIs, PCOS is characterized by numberous peripheral cysts where the ovaries affected to be slightly larger than normal. Although MRI is seen to be effective in ovarian imaging, the finding of peripheral ovarian cysts in MRIsmay not be PCOS specific. &amp;lt;ref&amp;gt;  http://www.ncbi.nlm.nih.gov/pubmed/8888256 &amp;lt;/ref&amp;gt; But studies have seen that MR imaging in adolescence uncover distinct differences between young patients with and without PCOS &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/23292744 &amp;lt;/ref&amp;gt;, with also great diagnostic sensitivity with patients between the age of 21-30 &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/19241321 &amp;lt;/ref&amp;gt;, providing assistance of imagery in patients whom may be opposed to transvaginal ultrasounds.&lt;br /&gt;
&lt;br /&gt;
=Prevention=&lt;br /&gt;
&lt;br /&gt;
==Impact of physical activity on ovarian reserve markers in normal, overweight and obese reproductive age women==&lt;br /&gt;
&amp;lt;pubmed&amp;gt;25509968&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study focuses on the effect of physical activity on fertility in three groups of women at reproductive age; normal, overweight and obese. The results from the study suggest that there was a marked improvement in fertility as shown by the ovarian reserve markers for all 3 groups, however it was most significant in the overweight and obese groups. This study is relevant to our project as it gives an insight into the preventative measures that can be taken for infertility. &lt;br /&gt;
&lt;br /&gt;
==Risk factors of polycystic ovarian syndrome among Li People==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;26276294&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study examined the risk factors entailed in Polycystic Ovarian Syndrdome (PCOS) amoung Li people. Using the method of a case control study, questionnaires were given to female Li people with and without PCOS. Analysis of the questionnaires showed that family history of diabetes, family history of infertility, bad mood, lack of physical exercise are all high risk factors of PCOS. As a result, management of these risk factors can be taken into consideration when preventing infertility through PCOS.&lt;br /&gt;
&lt;br /&gt;
==Vitamin D and female fertility==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;24717915&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article is a review focusing on research regarding Vitamin D and fertility over the past year. The review found that the levels of Vitamin D is crucial for women undergoing in-vitro fertilisation. It  was also found that Vitamin D was beneficial for women with PCOS and carried a protective effect against endometriosis. These observations suggest that having sufficient Vitamin D in your body can be preventative for problems associated with fertility.&lt;br /&gt;

| General Practitioners tend to prescribe oral anti-oestrogens, most commonly the contraceptive pill, to restore ovulation.&lt;br /&gt;
| This method only has a 50% success rate in PCOS patients. It does not directly increase fertility rates, but restores the menstrual cycle.&lt;br /&gt;
 &lt;br /&gt;

| Lifestyle changes are highly encouraged by medical practitioners. Diet and exercise regimes can be designed with a dietitian or nutritionist. &lt;br /&gt;
| Exercise and diet plans do not directly increase fertility. They are designed to enhance weight loss, which in some patients can encourage normal hormone levels from the pituitary and thyroid. &lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| Clomiphene citrate administration (generally in pill form, as prescribed by a GP). Such pills stimulate the pituitary gland to release GnRH to simulate ovulation (with a 72% success rate in the ___ trial). &lt;br /&gt;
| Clomiphene can cause multiple side effects, most notably abnormal uterine bleeding and pelvic pain to due enlargement of the ovaries. &lt;br /&gt;
&lt;br /&gt;
Thus, it cannot be as frequently prescribed as the contraceptive pill, and careful patient monitoring is imperative. &lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
===New Trials===&lt;br /&gt;
&lt;br /&gt;
Some studies have found that regular Selenium supplements can encourage fertility among PCOS patients. The program, which is still in its early trial period, requires women to consume selenium tablets for 8 weeks. This study has found a significant decrease in dehydroepiandrosterone (DHEA) levels in patients, thus reducing excessive hair growth associated with PCOS. A direct link to increased fertility is yet to be established, and thus further testing is required.&lt;br /&gt;

=Female Infertility=&lt;br /&gt;
&lt;br /&gt;
[[File:Prevalence of Primary Infertility in 2010.jpeg|400px|thumb|right|Prevalence of Primary Infertility in 2010]]&lt;br /&gt;
&lt;br /&gt;
Female Infertility refers to the failure to conceive after one year of regular unprotected intercourse in females &amp;lt;ref name=one&amp;gt;&amp;lt;pubmed&amp;gt;26150870&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. In 2010, infertility affected 48.5 million couples world wide and the areas of highest prevalence included North Africa and Middle East, South Asia, Central/Eastern Europe and Central Asia and Sub-Saharan Africa &amp;lt;ref name=two&amp;gt;&amp;lt;pubmed&amp;gt;23271957&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. As there are several causes of female infertility, we will be focusing on infertility that is caused by '''Polycystic Ovarian Syndrome''' (PCOS), the most common cause of infertility that is medically treatable &amp;lt;ref name=one/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Polycystic Ovarian Syndrome==&lt;br /&gt;
Polycystic Ovarian Syndrome (PCOS) is a common endocrine disorder, affecting up to 20% of reproductive aged women [3] It is the most common cause of anovulatory infertility [1] which refers to infertility caused by the the absence of ovulation.&lt;br /&gt;
&lt;br /&gt;
=Causes=&lt;br /&gt;
&lt;br /&gt;
PCOS is a disorder of heterogeneous origin with unknown aetiology &amp;lt;ref name=four&amp;gt;&amp;lt;pubmed&amp;gt;21896560&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Studies have shown that both genetic and environmental factors contribute to the development of PCOS in women however there is limited research into the actual interactions between these two factors &amp;lt;ref name=un&amp;gt;&amp;lt;pubmed&amp;gt;17185788&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Genetic Factors===&lt;br /&gt;
&lt;br /&gt;
Despite the lack of information regarding its aetiology, there is increasing evidence for a genetic involvement in the endocrine disorder. Studies have shown that genes play an important role in contributing towards the clinical and biochemical features of the disease &amp;lt;ref name=four/&amp;gt;. This evidence includes the family clustering of cases, greater unanimity between monozygotic twins than heterozygotic twins and the ability to inherit endocrine and  metabolic features of PCOS &amp;lt;ref name=four/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
In one study, 115 sisters of women with PCOS were examined and results showed that half of these sisters had high testosterone levels, suggesting that hyperandrogenemia is a common trait with a dominant pattern of inheritance. These results strongly supported the idea of the familial clustering of biochemical features such as hyperandrogenism in first degree relatives &amp;lt;ref name=deux&amp;gt;&amp;lt;pubmed&amp;gt;9843997&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
Several genes have been considered to play an important role in the development of PCOS such as CYP11A, the insulin gene, the follistatin gene and a region near the insulin receptor gene. Yet, the evidence supporting most of these genes has been refuted by larger studies, except for the region near the insulin receptor gene &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
There has been strong evidence linking the gene CYP11a with hyperandrogenism in women with PCOS. &amp;lt;ref name=cinq&amp;gt;&amp;lt;pubmed&amp;gt;9147642&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; While it doesn't isolate this gene as the sole cause of PCOS, variation of the genotype at this locus contributes to production of excess androgen &amp;lt;ref name=h4&amp;gt;&amp;lt;pubmed&amp;gt;7962289&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Studies have also shown that there is strong evidence for linkage between the alleles at the Variable Number Tandem Repeats (VNTR) which is situated 5' to the insulin gene and PCOS. The data from the study suggests that it is a very susceptible region in PCOS and also may play a role in the development of hyperinsulinaemia &amp;lt;ref name=trois&amp;gt;&amp;lt;pubmed&amp;gt;9455828&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
===Environmental Factors===&lt;br /&gt;
The prevalence of PCOS in populations where there has been a constant gene pool indicates that environmental factors play a significant role in the aetiology of PCOS.&lt;br /&gt;
&lt;br /&gt;
===Obesity and Diet===&lt;br /&gt;
Obesity is the major environmental factor driving the development of PCOS in susceptible individuals. The rising rates of PCOS have been paralleled by the widespread emergence of obesity and type 2 diabetes which are prevalent in developed countries. The risk of developing PCOS from obesity is compounded by  poor dietary choices and lack of physical activity which has begun to characterise the lifestyle in developed countries &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Medication===&lt;br /&gt;
Studies have shown that valproic acid in medication used to treat epilepsy and bipolar disorders contributes to the development of PCOS. Women with these disorders  may develop the typical features of PCOS such as polycystic ovaries, anovulation, hyperandrogenism and obesity &amp;lt;ref name=quartre&amp;gt;&amp;lt;pubmed&amp;gt;8413434&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Recent studies also suggest that the weight gain from medication is significant as it can lead to the development of PCOS &amp;lt;ref name=deux/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=Pathogenesis=&lt;br /&gt;
&lt;br /&gt;
The pathogenesis of polycystic ovarian syndrome is poorly understood, however it is believed that insulin resistance and excess androgens such as testosterone play a fundamental role.&lt;br /&gt;
Underlying factors such as obesity and genetic predispositions likely contribute to the onset of polycystic ovarian syndrome through the development of a combination of hyperinsulinemia and hyperandrogenemia.&amp;lt;ref name=eleven&amp;gt;&amp;lt;pubmed&amp;gt;PMC4556908&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
==Hyperinsulinemia==&lt;br /&gt;
&lt;br /&gt;
Hyperinsulinemia is a term that defines the presence of excessive amounts of insulin in the blood relative to the amount of glucose. &amp;lt;ref name=fourteen&amp;gt;&amp;lt;pubmed&amp;gt;PMC4114053&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; This phenomenon is typically associated with obesity and excess adipose tissue, both of which are associated with insulin resistance. In order to overcome this resistance, insulin secretion is increased in an attempt to normalise blood glucose levels, thereby leading to hyperinsulineamia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC2782313&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; Excessive levels of insulin typically cause disruption to the hypothalamus-hypophysis-ovary axis whilst insulin resistance in ovarian tissues leads to decreased metabolic signalling. However, steroidogenic activity is largely unaffected by the impaired metabolic signalling, thereby paving the way androgens to become more effect and paving the way towards hyperandrogenemia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
[[File:Patholophysiology of Polycystic Ovarian Syndrome.jpg|500px|thumb|left|The impact of hyperinsulinemia and hyperandrogenemia on the development of polycystic ovarian syndrome]]&lt;br /&gt;
&lt;br /&gt;
==Hyperandrogenemia==&lt;br /&gt;
&lt;br /&gt;
Hyperandrogenemia is a hallmark of the development of polycystic ovarian syndrome, with 80% of women presenting with excess androgen also having polycystic ovaries.&amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; The disruption of the hypothalamus hypophysis ovary axis as a result of hyperinsulinemia increases the release of GnRH and LH, leading to increased androgen production in the ovarian theca cells. Hyperandrogenemia decreases the feedback sensitivity of both estradiol and progesterone within gonadotropic hypothalmic cells. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; A deficiency of FSH is observed and correlates with the increased secretion of GnRH and LH. As a result of this deficiency, graunlosa  cell aromatisation to oestrogens as well as follicle maturation and ovulation will be drastically impaired.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3453528&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
As a consequence of the impairment of follicle maturation, small antral follicles will accumulate within the periphery of the ovary and develop a cystic morphology. Ovulation will be unable to occur due to the absence of mature follicles, culminating in infertility.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4562327&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Hyperandrogenism==&lt;br /&gt;
&lt;br /&gt;
===Animal Models===&lt;br /&gt;
&lt;br /&gt;
Studies conducted on female rhesus monkeys have supported evidence for the foetal origins of the clinical features of PCOS &amp;lt;ref name=h1&amp;gt;&amp;lt;pubmed&amp;gt;18406243&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.  It has been shown that in human females, an excess of androgen exposure at any stage from the development of the ovaries to the onset of puberty manifests as characteristic features of PCOS, such as resistance to insulin and Luteinising Hormone (LH) hypersecretion. After exposure to levels of testosterone matching those of fetal males, in utero, female rhesus monkeys were found to display the clinical and biochemical features typical of PCOS such as hypersecretion of LH and abnormal insulin action. These results correlated to those of similar studies conducted on sheep, where the pregnant ewe was exposed to excessive levels of testosterone and LH secretion and abnormality in ovarian cycles were again prominent features &amp;lt;ref name=sheep&amp;gt;Padmanabhan V, Evans NP, Taylor JA, Robinson JE1997 '''Prenatal exposure to  androgens  leads  to  the  development  of  cystic  ovaries  in  the  sheep'''. Biol Reprod 56:194&amp;lt;/ref&amp;gt;. While these studies indicate that similar biochemical and clinical manifestations in humans originate from excess androgen exposure of the female fetus, it must be noted that it is very unlikely for any excess androgen production to be passed across the placenta from the mother to her daughter. This is because mechanisms such as androgen binding proteins and placental metabolism of androgen prevent excess androgen entering the circulation of the fetus &amp;lt;ref name=h2&amp;gt;&amp;lt;pubmed&amp;gt;12098657&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
===Cell Culture Models===&lt;br /&gt;
&lt;br /&gt;
While studies have shown that the adrenal could be a source of excess androgen such as the adrenal &amp;lt;ref name=h3&amp;gt;&amp;lt;pubmed&amp;gt;7962325&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;, they were followed by various studies using cell culture models which demonstrated that the ovary was the major source of excess androgen &amp;lt;ref name=h4/&amp;gt; &amp;lt;ref name=h5&amp;gt;&amp;lt;pubmed&amp;gt;9302378&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. ''In vitro'' studies have shown that the production of steroids is abnormal in theca cells &amp;lt;ref name=h3/&amp;gt;. In women affected by PCOS, stimulation by human chorionic gonadotrophin (hCG) is followed by an increase in thecal steroid production after suppression of LH by a GnRH analogue &amp;lt;ref name=h5/&amp;gt;. Theca cells cultured from polycystic ovaries produce 20 times as much androstenedione as those from normal ovaries &amp;lt;ref name=h4/&amp;gt; with increased expression of mRNA for enzymes responsible for making steroids also reported in following studies. &amp;lt;ref name=h6&amp;gt;&amp;lt;pubmed&amp;gt;10852468&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; These results have prompted many studies on genes encoding these steroidogeneic enzymes.&lt;br /&gt;
&lt;br /&gt;

===The Genetics of Infertility: Current Status of the Field===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3885174&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article attempted to determine the role that genetics plays in female infertility. It was noted that several prominent causes of female infertility such as Galactosemia and Primary Ovarian Failure (POF) were associated with specific genes, with the GALT gene contributing to the former condition and the FMR1 gene contributing to the latter.&lt;br /&gt;
&lt;br /&gt;
===Causes of Sterility in Bosnia-Herzegovina Population===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC4499307&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
The study conducted as laid out in this article examined the causes of female sterility in the Bosnia-Herzegovina population. Married participants were arranged into various groups based upon their age. The experiment came to the conclusion that in approximately 42% of infertile married couples, female sterility was the primary cause. The two primary causes of female infertility were tubal deficiencies (31% of cases) and Diminished Ovarian Reserves (38% of cases)&lt;br /&gt;
&lt;br /&gt;
===Epidemiology, diagnosis, and management of polycystic ovary syndrome===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This research article examines the causes of polycystic ovary syndrome (POS), a common cause of infertility in women. The article concluded that 50-70% of women suffer from insulin resistance secondary to Type 2 Diabetes and in many cases obseity, which may contribute partially to POS. Furthermore, 85-90% of women with oligomenorrhea also had POS, suggesting that it is an underlying cause. However, the exact pathophysiology of POS was not determined.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Signs and Symptoms=&lt;br /&gt;
&lt;br /&gt;
The symptoms of PCOS are different for each women. The three cardinal signs of PCOS are hyperandrogenism, polycystic ovaries and ovarian dysfunction &amp;lt;ref name=sign1&amp;gt;&amp;lt;pubmed&amp;gt;14688154&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Common clinical symptoms include &amp;lt;ref&amp;gt; Women's Heath, U.S. Department of Health and Human Services ,[ http://www.womenshealth.gov/publications/our-publications/fact-sheet/polycystic-ovary-syndrome.html#d ], 'Polycystic ovary syndrome (PCOS) fact sheet'&amp;lt;/ref&amp;gt; ;&lt;br /&gt;
&lt;br /&gt;
- '''Infertility'''- Due to anovulation caused by PCOS. &lt;br /&gt;
- '''Irregular Menstrual Cycles'''&lt;br /&gt;
- '''Hirsutism'''&lt;br /&gt;

- '''Obesity'''&lt;br /&gt;
- '''Male Pattern Baldness '''&lt;br /&gt;
- '''Skin Tags'''&lt;br /&gt;
- '''Pelvic Pain'''&lt;br /&gt;
&lt;br /&gt;
Along with obesity, PCOS is also associated with other metabolic issues such as insulin resistance, hyperinsulinemia and type 2 diabetes mellitus. It has also been associated with cardiovascular problems and cancers of the breast and endometrium &amp;lt;ref name=sign3&amp;gt;&amp;lt;pubmed&amp;gt;PMC4341818&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Diagnosis=&lt;br /&gt;
&lt;br /&gt;
A major diagnostic tool for PCOS is a pelvic ultrasound, but PCOS diagnosis cannot be completely dependent on just pelvic ultrasounds. A patient with PCOS may not necessarily have polycystic ovaries, and those with ovarian cysts may not necessarily have PCOS. A range of diagnostic assessments and associated symptoms have to be thoroughly investigated.&lt;br /&gt;
&lt;br /&gt;
===Medical history and examination===&lt;br /&gt;
Clinical questions are asked or filled out in the form of a questionnaire to assess and assist in the diagnosis of PCOS. Studies show that those with a history:&lt;br /&gt;
*infrequent and irregular menstruation&lt;br /&gt;
*hirsutism (related to high levels of androgens in the blood – hyperandrogenism)&lt;br /&gt;
*obesity&lt;br /&gt;
*acne production &lt;br /&gt;
are at a higher predictive risk of PCOS. But questions regarding failed pregnancy attempts and history of nipple discharge proved no correlation in diagnosing PCOS. &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/17872783 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Blood Test===&lt;br /&gt;
A patient with elevated levels of androgens, a medical condition called &amp;lt;b&amp;gt;hyperandrogenism &amp;lt;/b&amp;gt;, is very highly likely to have PCOS. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/20591140 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&amp;lt;b&amp;gt; Androgens &amp;lt;/b&amp;gt; , such as testosterone, and &amp;lt;b&amp;gt;free androgen index (FAI) &amp;lt;/b&amp;gt; are the two tests best used in diagnosing hyperandrogenism.&lt;br /&gt;
Androgen excess in PCOS is a result from increased synthesis and release of ovarian androgens. &amp;lt;b&amp;gt;Dehydroepiandrosterone sulfate &amp;lt;/b&amp;gt; (DHEA-S) levels are used as a biomarker for testing androgen levels, as it is made exclusively by the adrenal glands. DHEA-S levels of above 1890 micromol/L is extremely suggestive of hyperandrogenism. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/18844715 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&amp;lt;b&amp;gt;Free androgen index (FAI) &amp;lt;/b&amp;gt; is the ratio of total testosterone measurement to levels of &amp;lt;b&amp;gt; sex hormone-binding globulin &amp;lt;/b&amp;gt; (SHBG). Those with PCOS will have high FAI, as this indicates a high ration of free testosterone in the body.&lt;br /&gt;
Other blood tests are also done to help exclude other predisposing factors such as levels of &amp;lt;b&amp;gt; Thyroid Stimulating Hormone &amp;lt;/b&amp;gt; (LSH) and &amp;lt;b&amp;gt; Follicle-stimulating hormone &amp;lt;/b&amp;gt; (FSH). An elevated ratio of LSH to FSH, of above 2:1 &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/14737959 &amp;lt;/ref&amp;gt;, indicates a possibility, but not definitively, of PCOS.&lt;br /&gt;
The effect of &amp;lt;b&amp;gt; insulin &amp;lt;/b&amp;gt; on blood can also be tested for insulin resistance. Insulin resistance enhances androgen production and increases free androgen levels by reducing SHBG. This can used as an indication marker for the possibility of PCOS&lt;br /&gt;
A study in 2014 showed that &amp;lt;b&amp;gt; Anti-Müllerian hormone &amp;lt;/b&amp;gt; (AMH) is found to be elevated in patients with PCOS &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24821925 &amp;lt;/ref&amp;gt;, giving rise to its potential clinical implication in diagnosing PCOS. AMH is exclusively produced in ovarian follicles, with individual AMH concentration reflecting the quantity of remaining primordial follicles and measure of ovarian reserve. &lt;br /&gt;
&lt;br /&gt;
===Gynecologic ultrasonography===&lt;br /&gt;
Gynecologic ultrasonography is a pelvic ultrasound, specifically to the female pelvic region, with regards to the uterus, ovaries and the fallopian tube. The examination can be performed by transabdominal ultrasonography, with a full bladder, or transvaginal ultrasonography with a vaginal transducer. Typically transvaginal imaging shows a better and clearer image than transabdominal ultrasonography, as it uses higher frequency imaging, but is limited to areas it can reach. In the case of PCOS, both techniques can provide an image of the ovaries. Studies suggest that if more than 25 follicles are seen in an ovary, predominantly in the periphery, in women between 18-35 years, it is described to have a polycystic ovarian morphology. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24345633 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Magnetic Resonance Imaging===&lt;br /&gt;
Ovaries can also be seen on MRIs. On MRIs, PCOS is characterized by numberous peripheral cysts where the ovaries affected to be slightly larger than normal. Although MRI is seen to be effective in ovarian imaging, the finding of peripheral ovarian cysts in MRIsmay not be PCOS specific. &amp;lt;ref&amp;gt;  http://www.ncbi.nlm.nih.gov/pubmed/8888256 &amp;lt;/ref&amp;gt; But studies have seen that MR imaging in adolescence uncover distinct differences between young patients with and without PCOS &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/23292744 &amp;lt;/ref&amp;gt;, with also great diagnostic sensitivity with patients between the age of 21-30 &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/19241321 &amp;lt;/ref&amp;gt;, providing assistance of imagery in patients whom may be opposed to transvaginal ultrasounds.&lt;br /&gt;
&lt;br /&gt;
=Prevention=&lt;br /&gt;
&lt;br /&gt;
==Impact of physical activity on ovarian reserve markers in normal, overweight and obese reproductive age women==&lt;br /&gt;
&amp;lt;pubmed&amp;gt;25509968&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study focuses on the effect of physical activity on fertility in three groups of women at reproductive age; normal, overweight and obese. The results from the study suggest that there was a marked improvement in fertility as shown by the ovarian reserve markers for all 3 groups, however it was most significant in the overweight and obese groups. This study is relevant to our project as it gives an insight into the preventative measures that can be taken for infertility. &lt;br /&gt;
&lt;br /&gt;
==Risk factors of polycystic ovarian syndrome among Li People==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;26276294&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study examined the risk factors entailed in Polycystic Ovarian Syndrdome (PCOS) amoung Li people. Using the method of a case control study, questionnaires were given to female Li people with and without PCOS. Analysis of the questionnaires showed that family history of diabetes, family history of infertility, bad mood, lack of physical exercise are all high risk factors of PCOS. As a result, management of these risk factors can be taken into consideration when preventing infertility through PCOS.&lt;br /&gt;
&lt;br /&gt;
==Vitamin D and female fertility==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;24717915&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article is a review focusing on research regarding Vitamin D and fertility over the past year. The review found that the levels of Vitamin D is crucial for women undergoing in-vitro fertilisation. It  was also found that Vitamin D was beneficial for women with PCOS and carried a protective effect against endometriosis. These observations suggest that having sufficient Vitamin D in your body can be preventative for problems associated with fertility.&lt;br /&gt;

===New Trials===&lt;br /&gt;
&lt;br /&gt;
Some studies have found that regular Selenium supplements can encourage fertility among PCOS patients. The program, which is still in its early trial period, requires women to consume selenium tablets for 8 weeks. This study has found a significant decrease in dehydroepiandrosterone (DHEA) levels in patients, thus reducing excessive hair growth associated with PCOS. A direct link to increased fertility is yet to be established, and thus further testing is required.&lt;br /&gt;

=Female Infertility=&lt;br /&gt;
&lt;br /&gt;
[[File:Prevalence of Primary Infertility in 2010.jpeg|400px|thumb|right|Prevalence of Primary Infertility in 2010]]&lt;br /&gt;
&lt;br /&gt;
Female Infertility refers to the failure to conceive after one year of regular unprotected intercourse in females &amp;lt;ref name=one&amp;gt;&amp;lt;pubmed&amp;gt;26150870&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. In 2010, infertility affected 48.5 million couples world wide and the areas of highest prevalence included North Africa and Middle East, South Asia, Central/Eastern Europe and Central Asia and Sub-Saharan Africa &amp;lt;ref name=two&amp;gt;&amp;lt;pubmed&amp;gt;23271957&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. As there are several causes of female infertility, we will be focusing on infertility that is caused by '''Polycystic Ovarian Syndrome''' (PCOS), the most common cause of infertility that is medically treatable &amp;lt;ref name=one/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Polycystic Ovarian Syndrome==&lt;br /&gt;
Polycystic Ovarian Syndrome (PCOS) is a common endocrine disorder, affecting up to 20% of reproductive aged women [3] It is the most common cause of anovulatory infertility [1] which refers to infertility caused by the the absence of ovulation.&lt;br /&gt;
&lt;br /&gt;
=Causes=&lt;br /&gt;
&lt;br /&gt;
PCOS is a disorder of heterogeneous origin with unknown aetiology &amp;lt;ref name=four&amp;gt;&amp;lt;pubmed&amp;gt;21896560&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Studies have shown that both genetic and environmental factors contribute to the development of PCOS in women however there is limited research into the actual interactions between these two factors &amp;lt;ref name=un&amp;gt;&amp;lt;pubmed&amp;gt;17185788&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Genetic Factors===&lt;br /&gt;
&lt;br /&gt;
Despite the lack of information regarding its aetiology, there is increasing evidence for a genetic involvement in the endocrine disorder. Studies have shown that genes play an important role in contributing towards the clinical and biochemical features of the disease &amp;lt;ref name=four/&amp;gt;. This evidence includes the family clustering of cases, greater unanimity between monozygotic twins than heterozygotic twins and the ability to inherit endocrine and  metabolic features of PCOS &amp;lt;ref name=four/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
In one study, 115 sisters of women with PCOS were examined and results showed that half of these sisters had high testosterone levels, suggesting that hyperandrogenemia is a common trait with a dominant pattern of inheritance. These results strongly supported the idea of the familial clustering of biochemical features such as hyperandrogenism in first degree relatives &amp;lt;ref name=deux&amp;gt;&amp;lt;pubmed&amp;gt;9843997&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
Several genes have been considered to play an important role in the development of PCOS such as CYP11A, the insulin gene, the follistatin gene and a region near the insulin receptor gene. Yet, the evidence supporting most of these genes has been refuted by larger studies, except for the region near the insulin receptor gene &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
There has been strong evidence linking the gene CYP11a with hyperandrogenism in women with PCOS. &amp;lt;ref name=cinq&amp;gt;&amp;lt;pubmed&amp;gt;9147642&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; While it doesn't isolate this gene as the sole cause of PCOS, variation of the genotype at this locus contributes to production of excess androgen &amp;lt;ref name=h4&amp;gt;&amp;lt;pubmed&amp;gt;7962289&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Studies have also shown that there is strong evidence for linkage between the alleles at the Variable Number Tandem Repeats (VNTR) which is situated 5' to the insulin gene and PCOS. The data from the study suggests that it is a very susceptible region in PCOS and also may play a role in the development of hyperinsulinaemia &amp;lt;ref name=trois&amp;gt;&amp;lt;pubmed&amp;gt;9455828&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
===Environmental Factors===&lt;br /&gt;
The prevalence of PCOS in populations where there has been a constant gene pool indicates that environmental factors play a significant role in the aetiology of PCOS.&lt;br /&gt;
&lt;br /&gt;
===Obesity and Diet===&lt;br /&gt;
Obesity is the major environmental factor driving the development of PCOS in susceptible individuals. The rising rates of PCOS have been paralleled by the widespread emergence of obesity and type 2 diabetes which are prevalent in developed countries. The risk of developing PCOS from obesity is compounded by  poor dietary choices and lack of physical activity which has begun to characterise the lifestyle in developed countries &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Medication===&lt;br /&gt;
Studies have shown that valproic acid in medication used to treat epilepsy and bipolar disorders contributes to the development of PCOS. Women with these disorders  may develop the typical features of PCOS such as polycystic ovaries, anovulation, hyperandrogenism and obesity &amp;lt;ref name=quartre&amp;gt;&amp;lt;pubmed&amp;gt;8413434&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Recent studies also suggest that the weight gain from medication is significant as it can lead to the development of PCOS &amp;lt;ref name=deux/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=Pathogenesis=&lt;br /&gt;
&lt;br /&gt;
The pathogenesis of polycystic ovarian syndrome is poorly understood, however it is believed that insulin resistance and excess androgens such as testosterone play a fundamental role.&lt;br /&gt;
Underlying factors such as obesity and genetic predispositions likely contribute to the onset of polycystic ovarian syndrome through the development of a combination of hyperinsulinemia and hyperandrogenemia.&amp;lt;ref name=eleven&amp;gt;&amp;lt;pubmed&amp;gt;PMC4556908&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
==Hyperinsulinemia==&lt;br /&gt;
&lt;br /&gt;
Hyperinsulinemia is a term that defines the presence of excessive amounts of insulin in the blood relative to the amount of glucose. &amp;lt;ref name=fourteen&amp;gt;&amp;lt;pubmed&amp;gt;PMC4114053&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; This phenomenon is typically associated with obesity and excess adipose tissue, both of which are associated with insulin resistance. In order to overcome this resistance, insulin secretion is increased in an attempt to normalise blood glucose levels, thereby leading to hyperinsulineamia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC2782313&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; Excessive levels of insulin typically cause disruption to the hypothalamus-hypophysis-ovary axis whilst insulin resistance in ovarian tissues leads to decreased metabolic signalling. However, steroidogenic activity is largely unaffected by the impaired metabolic signalling, thereby paving the way androgens to become more effect and paving the way towards hyperandrogenemia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
[[File:Patholophysiology of Polycystic Ovarian Syndrome.jpg|500px|thumb|left|The impact of hyperinsulinemia and hyperandrogenemia on the development of polycystic ovarian syndrome]]&lt;br /&gt;
&lt;br /&gt;
==Hyperandrogenemia==&lt;br /&gt;
&lt;br /&gt;
Hyperandrogenemia is a hallmark of the development of polycystic ovarian syndrome, with 80% of women presenting with excess androgen also having polycystic ovaries.&amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; The disruption of the hypothalamus hypophysis ovary axis as a result of hyperinsulinemia increases the release of GnRH and LH, leading to increased androgen production in the ovarian theca cells. Hyperandrogenemia decreases the feedback sensitivity of both estradiol and progesterone within gonadotropic hypothalmic cells. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; A deficiency of FSH is observed and correlates with the increased secretion of GnRH and LH. As a result of this deficiency, graunlosa  cell aromatisation to oestrogens as well as follicle maturation and ovulation will be drastically impaired.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3453528&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
As a consequence of the impairment of follicle maturation, small antral follicles will accumulate within the periphery of the ovary and develop a cystic morphology. Ovulation will be unable to occur due to the absence of mature follicles, culminating in infertility.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4562327&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Hyperandrogenism==&lt;br /&gt;
&lt;br /&gt;
===Animal Models===&lt;br /&gt;
&lt;br /&gt;
Studies conducted on female rhesus monkeys have supported evidence for the foetal origins of the clinical features of PCOS &amp;lt;ref name=h1&amp;gt;&amp;lt;pubmed&amp;gt;18406243&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.  It has been shown that in human females, an excess of androgen exposure at any stage from the development of the ovaries to the onset of puberty manifests as characteristic features of PCOS, such as resistance to insulin and Luteinising Hormone (LH) hypersecretion. After exposure to levels of testosterone matching those of fetal males, in utero, female rhesus monkeys were found to display the clinical and biochemical features typical of PCOS such as hypersecretion of LH and abnormal insulin action. These results correlated to those of similar studies conducted on sheep, where the pregnant ewe was exposed to excessive levels of testosterone and LH secretion and abnormality in ovarian cycles were again prominent features &amp;lt;ref name=sheep&amp;gt;Padmanabhan V, Evans NP, Taylor JA, Robinson JE1997 '''Prenatal exposure to  androgens  leads  to  the  development  of  cystic  ovaries  in  the  sheep'''. Biol Reprod 56:194&amp;lt;/ref&amp;gt;. While these studies indicate that similar biochemical and clinical manifestations in humans originate from excess androgen exposure of the female fetus, it must be noted that it is very unlikely for any excess androgen production to be passed across the placenta from the mother to her daughter. This is because mechanisms such as androgen binding proteins and placental metabolism of androgen prevent excess androgen entering the circulation of the fetus &amp;lt;ref name=h2&amp;gt;&amp;lt;pubmed&amp;gt;12098657&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
===Cell Culture Models===&lt;br /&gt;
&lt;br /&gt;
While studies have shown that the adrenal could be a source of excess androgen such as the adrenal &amp;lt;ref name=h3&amp;gt;&amp;lt;pubmed&amp;gt;7962325&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;, they were followed by various studies using cell culture models which demonstrated that the ovary was the major source of excess androgen &amp;lt;ref name=h4/&amp;gt; &amp;lt;ref name=h5&amp;gt;&amp;lt;pubmed&amp;gt;9302378&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. ''In vitro'' studies have shown that the production of steroids is abnormal in theca cells &amp;lt;ref name=h3/&amp;gt;. In women affected by PCOS, stimulation by human chorionic gonadotrophin (hCG) is followed by an increase in thecal steroid production after suppression of LH by a GnRH analogue &amp;lt;ref name=h5/&amp;gt;. Theca cells cultured from polycystic ovaries produce 20 times as much androstenedione as those from normal ovaries &amp;lt;ref name=h4/&amp;gt; with increased expression of mRNA for enzymes responsible for making steroids also reported in following studies. &amp;lt;ref name=h6&amp;gt;&amp;lt;pubmed&amp;gt;10852468&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; These results have prompted many studies on genes encoding these steroidogeneic enzymes.&lt;br /&gt;
&lt;br /&gt;

===The Genetics of Infertility: Current Status of the Field===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3885174&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article attempted to determine the role that genetics plays in female infertility. It was noted that several prominent causes of female infertility such as Galactosemia and Primary Ovarian Failure (POF) were associated with specific genes, with the GALT gene contributing to the former condition and the FMR1 gene contributing to the latter.&lt;br /&gt;
&lt;br /&gt;
===Causes of Sterility in Bosnia-Herzegovina Population===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC4499307&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
The study conducted as laid out in this article examined the causes of female sterility in the Bosnia-Herzegovina population. Married participants were arranged into various groups based upon their age. The experiment came to the conclusion that in approximately 42% of infertile married couples, female sterility was the primary cause. The two primary causes of female infertility were tubal deficiencies (31% of cases) and Diminished Ovarian Reserves (38% of cases)&lt;br /&gt;
&lt;br /&gt;
===Epidemiology, diagnosis, and management of polycystic ovary syndrome===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This research article examines the causes of polycystic ovary syndrome (POS), a common cause of infertility in women. The article concluded that 50-70% of women suffer from insulin resistance secondary to Type 2 Diabetes and in many cases obseity, which may contribute partially to POS. Furthermore, 85-90% of women with oligomenorrhea also had POS, suggesting that it is an underlying cause. However, the exact pathophysiology of POS was not determined.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Signs and Symptoms=&lt;br /&gt;
&lt;br /&gt;
The symptoms of PCOS are different for each women. The three cardinal signs of PCOS are hyperandrogenism, polycystic ovaries and ovarian dysfunction &amp;lt;ref name=sign1&amp;gt;&amp;lt;pubmed&amp;gt;14688154&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Common clinical symptoms include &amp;lt;ref&amp;gt; Women's Heath, U.S. Department of Health and Human Services ,[ http://www.womenshealth.gov/publications/our-publications/fact-sheet/polycystic-ovary-syndrome.html#d ], 'Polycystic ovary syndrome (PCOS) fact sheet'&amp;lt;/ref&amp;gt; ;&lt;br /&gt;

- '''Irregular Menstrual Cycles'''&lt;br /&gt;

- '''Obesity'''&lt;br /&gt;

- '''Skin Tags'''&lt;br /&gt;
- '''Pelvic Pain'''&lt;br /&gt;
&lt;br /&gt;
Along with obesity, PCOS is also associated with other metabolic issues such as insulin resistance, hyperinsulinemia and type 2 diabetes mellitus. It has also been associated with cardiovascular problems and cancers of the breast and endometrium &amp;lt;ref name=sign3&amp;gt;&amp;lt;pubmed&amp;gt;PMC4341818&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Diagnosis=&lt;br /&gt;
&lt;br /&gt;
A major diagnostic tool for PCOS is a pelvic ultrasound, but PCOS diagnosis cannot be completely dependent on just pelvic ultrasounds. A patient with PCOS may not necessarily have polycystic ovaries, and those with ovarian cysts may not necessarily have PCOS. A range of diagnostic assessments and associated symptoms have to be thoroughly investigated&lt;br /&gt;
&lt;br /&gt;
===Medical history and examination===&lt;br /&gt;
Clinical questions are asked or filled out in the form of a questionnaire to assess and assist in the diagnosis of PCOS. Studies show that those with a history:&lt;br /&gt;
*infrequent and irregular menstruation&lt;br /&gt;
*hirsutism (related to high levels of androgens in the blood – hyperandrogenism)&lt;br /&gt;
*obesity&lt;br /&gt;
*acne production &lt;br /&gt;
are at a higher predictive risk of PCOS. But questions regarding failed pregnancy attempts and history of nipple discharge proved no correlation in diagnosing PCOS. &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/17872783 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Blood Test==&lt;br /&gt;
A patient with elevated levels of androgens, hyperandrogenism, is very highly likely to have PCOS. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/20591140 &amp;lt;/ref&amp;gt;&lt;br /&gt;
Androgens, such as testosterone, and free androgen index (FAI) are the two tests best used in diagnosing hyperandrogenism.&lt;br /&gt;
Androgen excess in PCOS is a result from increased synthesis and release of ovarian androgens. Dehydroepiandrosterone sulfate (DHEA-S) levels are used as a biomarker for testing androgen levels, as it is made exclusively by the adrenal glands. DHEA-S levels of above 1890 micromol/L is extremely suggestive of hyperandrogenism. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/18844715 &amp;lt;/ref&amp;gt;&lt;br /&gt;
Free androgen index (FAI) is the ratio of total testosterone measurement to levels of sex hormone-binding globulin (SHBG). Those with PCOS will have high FAI, as this indicates a high ration of free testosterone in the body.&lt;br /&gt;
Other blood tests are also done to help exclude other predisposing factors such as levels of Thyroid Stimulating Hormone (LSH) and Follicle-stimulating hormone (FSH). An elevated ratio of LSH to FSH, of above 2:1 &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/14737959 &amp;lt;/ref&amp;gt;, indicates a possibility, but not definitively, of PCOS.&lt;br /&gt;
The effect of insulin on blood can also be tested for insulin resistance. Insulin resistance augments androgen production and increases free androgen levels by reducing SHBG. This can used as an indication marker for the possibility of PCOS&lt;br /&gt;
A study in 2014 showed that Anti-Müllerian hormone (AMH) is found to be elevated in patients with PCOS &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24821925 &amp;lt;/ref&amp;gt;, giving rise to its potential clinical implication in diagnosing PCOS. AMH is exclusively produced in ovarian follicles, with individual AMH concentration reflecting the quantity of remaining primordial follicles and measure of ovarian reserve. &lt;br /&gt;
&lt;br /&gt;
==Gynecologic ultrasonography==&lt;br /&gt;
Gynecologic ultrasonography is a pelvic ultrasound, specifically to the female pelvic region, with regards to the uterus, ovaries and the fallopian tube. The examination can be performed by transabdominal ultrasonography, with a full bladder, or transvaginal ultrasonography with a vaginal transducer. Typically transvaginal imaging shows a better and clearer image than transabdominal ultrasonography, as it uses higher frequency imaging, but is limited to areas it can reach. In the case of PCOS, both techniques can provide an image of the ovaries. Studies suggest that if more than 25 follicles are seen in an ovary, predominantly in the periphery, in women between 18-35 years, it is described to have a polycystic ovarian morphology. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24345633 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Magnetic Resonance Imaging==&lt;br /&gt;
Ovaries can also be seen on MRIs. On MRIs, PCOS is characterized by numberous peripheral cysts where the ovaries affected to be slightly larger than normal. Although MRI is seen to be effective in ovarian imaging, the finding of peripheral ovarian cysts in MRIsmay not be PCOS specific. &amp;lt;ref&amp;gt;  http://www.ncbi.nlm.nih.gov/pubmed/8888256 &amp;lt;/ref&amp;gt; But studies have seen that MR imaging in adolescence uncover distinct differences between young patients with and without PCOS &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/23292744 &amp;lt;/ref&amp;gt;, with also great diagnostic sensitivity with patients between the age of 21-30 &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/19241321 &amp;lt;/ref&amp;gt;, providing assistance of imagery in patients whom may be opposed to transvaginal ultrasounds.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Prevention=&lt;br /&gt;
&lt;br /&gt;
==Impact of physical activity on ovarian reserve markers in normal, overweight and obese reproductive age women==&lt;br /&gt;
&amp;lt;pubmed&amp;gt;25509968&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study focuses on the effect of physical activity on fertility in three groups of women at reproductive age; normal, overweight and obese. The results from the study suggest that there was a marked improvement in fertility as shown by the ovarian reserve markers for all 3 groups, however it was most significant in the overweight and obese groups. This study is relevant to our project as it gives an insight into the preventative measures that can be taken for infertility. &lt;br /&gt;
&lt;br /&gt;
==Risk factors of polycystic ovarian syndrome among Li People==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;26276294&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study examined the risk factors entailed in Polycystic Ovarian Syndrdome (PCOS) amoung Li people. Using the method of a case control study, questionnaires were given to female Li people with and without PCOS. Analysis of the questionnaires showed that family history of diabetes, family history of infertility, bad mood, lack of physical exercise are all high risk factors of PCOS. As a result, management of these risk factors can be taken into consideration when preventing infertility through PCOS.&lt;br /&gt;
&lt;br /&gt;
==Vitamin D and female fertility==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;24717915&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article is a review focusing on research regarding Vitamin D and fertility over the past year. The review found that the levels of Vitamin D is crucial for women undergoing in-vitro fertilisation. It  was also found that Vitamin D was beneficial for women with PCOS and carried a protective effect against endometriosis. These observations suggest that having sufficient Vitamin D in your body can be preventative for problems associated with fertility.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Treatment=&lt;br /&gt;
&lt;br /&gt;
===Current Treatments===&lt;br /&gt;

| '''CURRENT TREATMENT'''&lt;br /&gt;
| '''DISADVANTAGES'''&lt;br /&gt;
|-&lt;br /&gt;
| General Practitioners tend to prescribe oral anti-oestrogens, most commonly the contraceptive pill, to restore ovulation.&lt;br /&gt;
| This method only has a 50% success rate in PCOS patients. It does not directly increase fertility rates, but restores the menstrual cycle.&lt;br /&gt;
 &lt;br /&gt;
|-bgcolor=&amp;quot;FAF5FF&amp;quot;&lt;br /&gt;
| Lifestyle changes are highly encouraged by medical practitioners. Diet and exercise regimes can be designed with a dietitian or nutritionist. &lt;br /&gt;
| Exercise and diet plans do not directly increase fertility. They are designed to enhance weight loss, which in some patients can encourage normal hormone levels from the pituitary and thyroid. &lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
===New Trials===&lt;br /&gt;
&lt;br /&gt;
Some studies have found that regular Selenium supplements can encourage fertility among PCOS patients. The program, which is still in its early trial period, requires women to consume selenium tablets for 8 weeks. This study has found a significant decrease in dehydroepiandrosterone (DHEA) levels in patients, thus reducing excessive hair growth associated with PCOS. A direct link to increased fertility is yet to be established, and thus further testing is required.&lt;br /&gt;

=Female Infertility=&lt;br /&gt;
&lt;br /&gt;
[[File:Prevalence of Primary Infertility in 2010.jpeg|400px|thumb|right|Prevalence of Primary Infertility in 2010]]&lt;br /&gt;
&lt;br /&gt;
Female Infertility refers to the failure to conceive after one year of regular unprotected intercourse in females &amp;lt;ref name=one&amp;gt;&amp;lt;pubmed&amp;gt;26150870&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. In 2010, infertility affected 48.5 million couples world wide and the areas of highest prevalence included North Africa and Middle East, South Asia, Central/Eastern Europe and Central Asia and Sub-Saharan Africa &amp;lt;ref name=two&amp;gt;&amp;lt;pubmed&amp;gt;23271957&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. As there are several causes of female infertility, we will be focusing on infertility that is caused by '''Polycystic Ovarian Syndrome''' (PCOS), the most common cause of infertility that is medically treatable &amp;lt;ref name=one/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Polycystic Ovarian Syndrome==&lt;br /&gt;
Polycystic Ovarian Syndrome (PCOS) is a common endocrine disorder, affecting up to 20% of reproductive aged women [3] It is the most common cause of anovulatory infertility [1] which refers to infertility caused by the the absence of ovulation.&lt;br /&gt;
&lt;br /&gt;
=Causes=&lt;br /&gt;
&lt;br /&gt;
PCOS is a disorder of heterogeneous origin with unknown aetiology &amp;lt;ref name=four&amp;gt;&amp;lt;pubmed&amp;gt;21896560&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Studies have shown that both genetic and environmental factors contribute to the development of PCOS in women however there is limited research into the actual interactions between these two factors &amp;lt;ref name=un&amp;gt;&amp;lt;pubmed&amp;gt;17185788&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Genetic Factors===&lt;br /&gt;
&lt;br /&gt;
Despite the lack of information regarding its aetiology, there is increasing evidence for a genetic involvement in the endocrine disorder. Studies have shown that genes play an important role in contributing towards the clinical and biochemical features of the disease &amp;lt;ref name=four/&amp;gt;. This evidence includes the family clustering of cases, greater unanimity between monozygotic twins than heterozygotic twins and the ability to inherit endocrine and  metabolic features of PCOS &amp;lt;ref name=four/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
In one study, 115 sisters of women with PCOS were examined and results showed that half of these sisters had high testosterone levels, suggesting that hyperandrogenemia is a common trait with a dominant pattern of inheritance. These results strongly supported the idea of the familial clustering of biochemical features such as hyperandrogenism in first degree relatives &amp;lt;ref name=deux&amp;gt;&amp;lt;pubmed&amp;gt;9843997&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
Several genes have been considered to play an important role in the development of PCOS such as CYP11A, the insulin gene, the follistatin gene and a region near the insulin receptor gene. Yet, the evidence supporting most of these genes has been refuted by larger studies, except for the region near the insulin receptor gene &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
There has been strong evidence linking the gene CYP11a with hyperandrogenism in women with PCOS. &amp;lt;ref name=cinq&amp;gt;&amp;lt;pubmed&amp;gt;9147642&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; While it doesn't isolate this gene as the sole cause of PCOS, variation of the genotype at this locus contributes to production of excess androgen &amp;lt;ref name=h4&amp;gt;&amp;lt;pubmed&amp;gt;7962289&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Studies have also shown that there is strong evidence for linkage between the alleles at the Variable Number Tandem Repeats (VNTR) which is situated 5' to the insulin gene and PCOS. The data from the study suggests that it is a very susceptible region in PCOS and also may play a role in the development of hyperinsulinaemia &amp;lt;ref name=trois&amp;gt;&amp;lt;pubmed&amp;gt;9455828&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
===Environmental Factors===&lt;br /&gt;
The prevalence of PCOS in populations where there has been a constant gene pool indicates that environmental factors play a significant role in the aetiology of PCOS.&lt;br /&gt;
&lt;br /&gt;
===Obesity and Diet===&lt;br /&gt;
Obesity is the major environmental factor driving the development of PCOS in susceptible individuals. The rising rates of PCOS have been paralleled by the widespread emergence of obesity and type 2 diabetes which are prevalent in developed countries. The risk of developing PCOS from obesity is compounded by  poor dietary choices and lack of physical activity which has begun to characterise the lifestyle in developed countries &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Medication===&lt;br /&gt;
Studies have shown that valproic acid in medication used to treat epilepsy and bipolar disorders contributes to the development of PCOS. Women with these disorders  may develop the typical features of PCOS such as polycystic ovaries, anovulation, hyperandrogenism and obesity &amp;lt;ref name=quartre&amp;gt;&amp;lt;pubmed&amp;gt;8413434&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Recent studies also suggest that the weight gain from medication is significant as it can lead to the development of PCOS &amp;lt;ref name=deux/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=Pathogenesis=&lt;br /&gt;
&lt;br /&gt;
The pathogenesis of polycystic ovarian syndrome is poorly understood, however it is believed that insulin resistance and excess androgens such as testosterone play a fundamental role.&lt;br /&gt;
Underlying factors such as obesity and genetic predispositions likely contribute to the onset of polycystic ovarian syndrome through the development of a combination of hyperinsulinemia and hyperandrogenemia.&amp;lt;ref name=eleven&amp;gt;&amp;lt;pubmed&amp;gt;PMC4556908&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
==Hyperinsulinemia==&lt;br /&gt;
&lt;br /&gt;
Hyperinsulinemia is a term that defines the presence of excessive amounts of insulin in the blood relative to the amount of glucose. &amp;lt;ref name=fourteen&amp;gt;&amp;lt;pubmed&amp;gt;PMC4114053&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; This phenomenon is typically associated with obesity and excess adipose tissue, both of which are associated with insulin resistance. In order to overcome this resistance, insulin secretion is increased in an attempt to normalise blood glucose levels, thereby leading to hyperinsulineamia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC2782313&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; Excessive levels of insulin typically cause disruption to the hypothalamus-hypophysis-ovary axis whilst insulin resistance in ovarian tissues leads to decreased metabolic signalling. However, steroidogenic activity is largely unaffected by the impaired metabolic signalling, thereby paving the way androgens to become more effect and paving the way towards hyperandrogenemia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
[[File:Patholophysiology of Polycystic Ovarian Syndrome.jpg|500px|thumb|left|The impact of hyperinsulinemia and hyperandrogenemia on the development of polycystic ovarian syndrome]]&lt;br /&gt;
&lt;br /&gt;
==Hyperandrogenemia==&lt;br /&gt;
&lt;br /&gt;
Hyperandrogenemia is a hallmark of the development of polycystic ovarian syndrome, with 80% of women presenting with excess androgen also having polycystic ovaries.&amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; The disruption of the hypothalamus hypophysis ovary axis as a result of hyperinsulinemia increases the release of GnRH and LH, leading to increased androgen production in the ovarian theca cells. Hyperandrogenemia decreases the feedback sensitivity of both estradiol and progesterone within gonadotropic hypothalmic cells. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; A deficiency of FSH is observed and correlates with the increased secretion of GnRH and LH. As a result of this deficiency, graunlosa  cell aromatisation to oestrogens as well as follicle maturation and ovulation will be drastically impaired.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3453528&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
As a consequence of the impairment of follicle maturation, small antral follicles will accumulate within the periphery of the ovary and develop a cystic morphology. Ovulation will be unable to occur due to the absence of mature follicles, culminating in infertility.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4562327&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Hyperandrogenism==&lt;br /&gt;
&lt;br /&gt;
===Animal Models===&lt;br /&gt;
&lt;br /&gt;
Studies conducted on female rhesus monkeys have supported evidence for the foetal origins of the clinical features of PCOS &amp;lt;ref name=h1&amp;gt;&amp;lt;pubmed&amp;gt;18406243&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.  It has been shown that in human females, an excess of androgen exposure at any stage from the development of the ovaries to the onset of puberty manifests as characteristic features of PCOS, such as resistance to insulin and Luteinising Hormone (LH) hypersecretion. After exposure to levels of testosterone matching those of fetal males, in utero, female rhesus monkeys were found to display the clinical and biochemical features typical of PCOS such as hypersecretion of LH and abnormal insulin action. These results correlated to those of similar studies conducted on sheep, where the pregnant ewe was exposed to excessive levels of testosterone and LH secretion and abnormality in ovarian cycles were again prominent features &amp;lt;ref name=sheep&amp;gt;Padmanabhan V, Evans NP, Taylor JA, Robinson JE1997 '''Prenatal exposure to  androgens  leads  to  the  development  of  cystic  ovaries  in  the  sheep'''. Biol Reprod 56:194&amp;lt;/ref&amp;gt;. While these studies indicate that similar biochemical and clinical manifestations in humans originate from excess androgen exposure of the female fetus, it must be noted that it is very unlikely for any excess androgen production to be passed across the placenta from the mother to her daughter. This is because mechanisms such as androgen binding proteins and placental metabolism of androgen prevent excess androgen entering the circulation of the fetus &amp;lt;ref name=h2&amp;gt;&amp;lt;pubmed&amp;gt;12098657&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
===Cell Culture Models===&lt;br /&gt;
&lt;br /&gt;
While studies have shown that the adrenal could be a source of excess androgen such as the adrenal &amp;lt;ref name=h3&amp;gt;&amp;lt;pubmed&amp;gt;7962325&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;, they were followed by various studies using cell culture models which demonstrated that the ovary was the major source of excess androgen &amp;lt;ref name=h4/&amp;gt; &amp;lt;ref name=h5&amp;gt;&amp;lt;pubmed&amp;gt;9302378&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. ''In vitro'' studies have shown that the production of steroids is abnormal in theca cells &amp;lt;ref name=h3/&amp;gt;. In women affected by PCOS, stimulation by human chorionic gonadotrophin (hCG) is followed by an increase in thecal steroid production after suppression of LH by a GnRH analogue &amp;lt;ref name=h5/&amp;gt;. Theca cells cultured from polycystic ovaries produce 20 times as much androstenedione as those from normal ovaries &amp;lt;ref name=h4/&amp;gt; with increased expression of mRNA for enzymes responsible for making steroids also reported in following studies. &amp;lt;ref name=h6&amp;gt;&amp;lt;pubmed&amp;gt;10852468&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; These results have prompted many studies on genes encoding these steroidogeneic enzymes.&lt;br /&gt;
&lt;br /&gt;

===The Genetics of Infertility: Current Status of the Field===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3885174&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article attempted to determine the role that genetics plays in female infertility. It was noted that several prominent causes of female infertility such as Galactosemia and Primary Ovarian Failure (POF) were associated with specific genes, with the GALT gene contributing to the former condition and the FMR1 gene contributing to the latter.&lt;br /&gt;
&lt;br /&gt;
===Causes of Sterility in Bosnia-Herzegovina Population===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC4499307&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
The study conducted as laid out in this article examined the causes of female sterility in the Bosnia-Herzegovina population. Married participants were arranged into various groups based upon their age. The experiment came to the conclusion that in approximately 42% of infertile married couples, female sterility was the primary cause. The two primary causes of female infertility were tubal deficiencies (31% of cases) and Diminished Ovarian Reserves (38% of cases)&lt;br /&gt;
&lt;br /&gt;
===Epidemiology, diagnosis, and management of polycystic ovary syndrome===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This research article examines the causes of polycystic ovary syndrome (POS), a common cause of infertility in women. The article concluded that 50-70% of women suffer from insulin resistance secondary to Type 2 Diabetes and in many cases obseity, which may contribute partially to POS. Furthermore, 85-90% of women with oligomenorrhea also had POS, suggesting that it is an underlying cause. However, the exact pathophysiology of POS was not determined.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Signs and Symptoms=&lt;br /&gt;
&lt;br /&gt;
The symptoms of PCOS are different for each women. The three cardinal signs of PCOS are hyperandrogenism, polycystic ovaries and ovarian dysfunction &amp;lt;ref name=sign1&amp;gt;&amp;lt;pubmed&amp;gt;14688154&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Common clinical symptoms include &amp;lt;ref&amp;gt; Women's Heath, U.S. Department of Health and Human Services ,[ http://www.womenshealth.gov/publications/our-publications/fact-sheet/polycystic-ovary-syndrome.html#d ], 'Polycystic ovary syndrome (PCOS) fact sheet'&amp;lt;/ref&amp;gt; ;&lt;br /&gt;
&lt;br /&gt;
- '''Infertility'''- Due to anovulation caused by PCOS. &lt;br /&gt;
- '''Irregular Menstrual Cycles'''&lt;br /&gt;
- '''Hirsutism'''&lt;br /&gt;
- '''Ovarian Cysts'''&lt;br /&gt;
- '''Obesity'''&lt;br /&gt;
- '''Male Pattern Baldness '''&lt;br /&gt;
- '''Skin Tags'''&lt;br /&gt;
- '''Pelvic Pain'''&lt;br /&gt;
&lt;br /&gt;
Along with obesity, PCOS is also associated with other metabolic issues such as insulin resistance, hyperinsulinemia and type 2 diabetes mellitus. It has also been associated with cardiovascular problems and cancers of the breast and endometrium &amp;lt;ref name=sign3&amp;gt;&amp;lt;pubmed&amp;gt;PMC4341818&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Diagnosis=&lt;br /&gt;
&lt;br /&gt;
A major diagnostic tool for PCOS is a pelvic ultrasound, but PCOS diagnosis cannot be completely dependent on just pelvic ultrasounds. A patient with PCOS may not necessarily have polycystic ovaries, and those with ovarian cysts may not necessarily have PCOS. A range of diagnostic assessments and associated symptoms have to be thoroughly investigated&lt;br /&gt;
&lt;br /&gt;
==Medical history and examination==&lt;br /&gt;
Clinical questions are asked or filled out in the form of a questionnaire to assess and assist in the diagnosis of PCOS. Studies show that those with a history:&lt;br /&gt;
*infrequent and irregular menstruation&lt;br /&gt;
*hirsutism (related to high levels of androgens in the blood – hyperandrogenism)&lt;br /&gt;
*obesity&lt;br /&gt;
*acne production &lt;br /&gt;
are at a higher predictive risk of PCOS. But questions regarding failed pregnancy attempts and history of nipple discharge proved no correlation in diagnosing PCOS. &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/17872783 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Blood Test==&lt;br /&gt;
A patient with elevated levels of androgens, hyperandrogenism, is very highly likely to have PCOS. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/20591140 &amp;lt;/ref&amp;gt;&lt;br /&gt;
Androgens, such as testosterone, and free androgen index (FAI) are the two tests best used in diagnosing hyperandrogenism.&lt;br /&gt;
Androgen excess in PCOS is a result from increased synthesis and release of ovarian androgens. Dehydroepiandrosterone sulfate (DHEA-S) levels are used as a biomarker for testing androgen levels, as it is made exclusively by the adrenal glands. DHEA-S levels of above 1890 micromol/L is extremely suggestive of hyperandrogenism. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/18844715 &amp;lt;/ref&amp;gt;&lt;br /&gt;
Free androgen index (FAI) is the ratio of total testosterone measurement to levels of sex hormone-binding globulin (SHBG). Those with PCOS will have high FAI, as this indicates a high ration of free testosterone in the body.&lt;br /&gt;
Other blood tests are also done to help exclude other predisposing factors such as levels of Thyroid Stimulating Hormone (LSH) and Follicle-stimulating hormone (FSH). An elevated ratio of LSH to FSH, of above 2:1 &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/14737959 &amp;lt;/ref&amp;gt;, indicates a possibility, but not definitively, of PCOS.&lt;br /&gt;
The effect of insulin on blood can also be tested for insulin resistance. Insulin resistance augments androgen production and increases free androgen levels by reducing SHBG. This can used as an indication marker for the possibility of PCOS&lt;br /&gt;
A study in 2014 showed that Anti-Müllerian hormone (AMH) is found to be elevated in patients with PCOS &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24821925 &amp;lt;/ref&amp;gt;, giving rise to its potential clinical implication in diagnosing PCOS. AMH is exclusively produced in ovarian follicles, with individual AMH concentration reflecting the quantity of remaining primordial follicles and measure of ovarian reserve. &lt;br /&gt;
&lt;br /&gt;
==Gynecologic ultrasonography==&lt;br /&gt;
Gynecologic ultrasonography is a pelvic ultrasound, specifically to the female pelvic region, with regards to the uterus, ovaries and the fallopian tube. The examination can be performed by transabdominal ultrasonography, with a full bladder, or transvaginal ultrasonography with a vaginal transducer. Typically transvaginal imaging shows a better and clearer image than transabdominal ultrasonography, as it uses higher frequency imaging, but is limited to areas it can reach. In the case of PCOS, both techniques can provide an image of the ovaries. Studies suggest that if more than 25 follicles are seen in an ovary, predominantly in the periphery, in women between 18-35 years, it is described to have a polycystic ovarian morphology. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24345633 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Magnetic Resonance Imaging==&lt;br /&gt;
Ovaries can also be seen on MRIs. On MRIs, PCOS is characterized by numberous peripheral cysts where the ovaries affected to be slightly larger than normal. Although MRI is seen to be effective in ovarian imaging, the finding of peripheral ovarian cysts in MRIsmay not be PCOS specific. &amp;lt;ref&amp;gt;  http://www.ncbi.nlm.nih.gov/pubmed/8888256 &amp;lt;/ref&amp;gt; But studies have seen that MR imaging in adolescence uncover distinct differences between young patients with and without PCOS &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/23292744 &amp;lt;/ref&amp;gt;, with also great diagnostic sensitivity with patients between the age of 21-30 &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/19241321 &amp;lt;/ref&amp;gt;, providing assistance of imagery in patients whom may be opposed to transvaginal ultrasounds.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Prevention=&lt;br /&gt;
&lt;br /&gt;
==Impact of physical activity on ovarian reserve markers in normal, overweight and obese reproductive age women==&lt;br /&gt;
&amp;lt;pubmed&amp;gt;25509968&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study focuses on the effect of physical activity on fertility in three groups of women at reproductive age; normal, overweight and obese. The results from the study suggest that there was a marked improvement in fertility as shown by the ovarian reserve markers for all 3 groups, however it was most significant in the overweight and obese groups. This study is relevant to our project as it gives an insight into the preventative measures that can be taken for infertility. &lt;br /&gt;
&lt;br /&gt;
==Risk factors of polycystic ovarian syndrome among Li People==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;26276294&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study examined the risk factors entailed in Polycystic Ovarian Syndrdome (PCOS) amoung Li people. Using the method of a case control study, questionnaires were given to female Li people with and without PCOS. Analysis of the questionnaires showed that family history of diabetes, family history of infertility, bad mood, lack of physical exercise are all high risk factors of PCOS. As a result, management of these risk factors can be taken into consideration when preventing infertility through PCOS.&lt;br /&gt;
&lt;br /&gt;
==Vitamin D and female fertility==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;24717915&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article is a review focusing on research regarding Vitamin D and fertility over the past year. The review found that the levels of Vitamin D is crucial for women undergoing in-vitro fertilisation. It  was also found that Vitamin D was beneficial for women with PCOS and carried a protective effect against endometriosis. These observations suggest that having sufficient Vitamin D in your body can be preventative for problems associated with fertility.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Treatment=&lt;br /&gt;
&lt;br /&gt;
===Current Treatments===&lt;br /&gt;
&lt;br /&gt;
{|border=&amp;quot;1&amp;quot;&lt;br /&gt;
|-bgcolor=&amp;quot;DDCEF2&amp;quot;&lt;br /&gt;
| '''CURRENT TREATMENT'''&lt;br /&gt;
| '''DISADVANTAGES'''&lt;br /&gt;
|-&lt;br /&gt;
| General Practitioners tend to prescribe oral anti-oestrogens, most commonly the contraceptive pill, to restore ovulation.&lt;br /&gt;
| This method only has a 50% success rate in PCOS patients. It does not directly increase fertility rates, but restores the menstrual cycle.&lt;br /&gt;
 &lt;br /&gt;
|-bgcolor=&amp;quot;FAF5FF&amp;quot;&lt;br /&gt;
| Lifestyle changes are highly encouraged by medical practitioners. Diet and exercise regimes can be designed with a dietitian or nutritionist. &lt;br /&gt;
| Exercise and diet plans do not directly increase fertility. They are designed to enhance weight loss, which in some patients can encourage normal hormone levels from the pituitary and thyroid. &lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| Clomiphene citrate administration (generally in pill form, as prescribed by a GP). Such pills stimulate the pituitary gland to release GnRH to simulate ovulation (with a 72% success rate in the ___ trial). &lt;br /&gt;
| Clomiphene can cause multiple side effects, most notably abnormal uterine bleeding and pelvic pain to due enlargement of the ovaries. &lt;br /&gt;
&lt;br /&gt;
Thus, it cannot be as frequently prescribed as the contraceptive pill, and careful patient monitoring is imperative. &lt;br /&gt;
&lt;br /&gt;
|-bgcolor=&amp;quot;FAF5FF&amp;quot;&lt;br /&gt;
| Higher fertility rates are observed in treatments combining clomiphene citrate and metformin (79% success).&lt;br /&gt;
| Similar disadvantages as clomiphene, above.&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
===New Trials===&lt;br /&gt;
&lt;br /&gt;
Some studies have found that regular Selenium supplements can encourage fertility among PCOS patients. The program, which is still in its early trial period, requires women to consume selenium tablets for 8 weeks. This study has found a significant decrease in dehydroepiandrosterone (DHEA) levels in patients, thus reducing excessive hair growth associated with PCOS. A direct link to increased fertility is yet to be established, and thus further testing is required.&lt;br /&gt;

=Female Infertility=&lt;br /&gt;
&lt;br /&gt;
[[File:Prevalence of Primary Infertility in 2010.jpeg|400px|thumb|right|Prevalence of Primary Infertility in 2010]]&lt;br /&gt;
&lt;br /&gt;
Female Infertility refers to the failure to conceive after one year of regular unprotected intercourse in females &amp;lt;ref name=one&amp;gt;&amp;lt;pubmed&amp;gt;26150870&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. In 2010, infertility affected 48.5 million couples world wide and the areas of highest prevalence included North Africa and Middle East, South Asia, Central/Eastern Europe and Central Asia and Sub-Saharan Africa &amp;lt;ref name=two&amp;gt;&amp;lt;pubmed&amp;gt;23271957&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. As there are several causes of female infertility, we will be focusing on infertility that is caused by '''Polycystic Ovarian Syndrome''' (PCOS), the most common cause of infertility that is medically treatable &amp;lt;ref name=one/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Polycystic Ovarian Syndrome==&lt;br /&gt;
Polycystic Ovarian Syndrome (PCOS) is a common endocrine disorder, affecting up to 20% of reproductive aged women [3] It is the most common cause of anovulatory infertility [1] which refers to infertility caused by the the absence of ovulation.&lt;br /&gt;
&lt;br /&gt;
=Causes=&lt;br /&gt;
&lt;br /&gt;
PCOS is a disorder of heterogeneous origin with unknown aetiology &amp;lt;ref name=four&amp;gt;&amp;lt;pubmed&amp;gt;21896560&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Studies have shown that both genetic and environmental factors contribute to the development of PCOS in women however there is limited research into the actual interactions between these two factors &amp;lt;ref name=un&amp;gt;&amp;lt;pubmed&amp;gt;17185788&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Genetic Factors===&lt;br /&gt;
&lt;br /&gt;
Despite the lack of information regarding its aetiology, there is increasing evidence for a genetic involvement in the endocrine disorder. Studies have shown that genes play an important role in contributing towards the clinical and biochemical features of the disease &amp;lt;ref name=four/&amp;gt;. This evidence includes the family clustering of cases, greater unanimity between monozygotic twins than heterozygotic twins and the ability to inherit endocrine and  metabolic features of PCOS &amp;lt;ref name=four/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
In one study, 115 sisters of women with PCOS were examined and results showed that half of these sisters had high testosterone levels, suggesting that hyperandrogenemia is a common trait with a dominant pattern of inheritance. These results strongly supported the idea of the familial clustering of biochemical features such as hyperandrogenism in first degree relatives &amp;lt;ref name=deux&amp;gt;&amp;lt;pubmed&amp;gt;9843997&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
Several genes have been considered to play an important role in the development of PCOS such as CYP11A, the insulin gene, the follistatin gene and a region near the insulin receptor gene. Yet, the evidence supporting most of these genes has been refuted by larger studies, except for the region near the insulin receptor gene &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
There has been strong evidence linking the gene CYP11a with hyperandrogenism in women with PCOS. &amp;lt;ref name=cinq&amp;gt;&amp;lt;pubmed&amp;gt;9147642&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; While it doesn't isolate this gene as the sole cause of PCOS, variation of the genotype at this locus contributes to production of excess androgen &amp;lt;ref name=h4&amp;gt;&amp;lt;pubmed&amp;gt;7962289&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Studies have also shown that there is strong evidence for linkage between the alleles at the Variable Number Tandem Repeats (VNTR) which is situated 5' to the insulin gene and PCOS. The data from the study suggests that it is a very susceptible region in PCOS and also may play a role in the development of hyperinsulinaemia &amp;lt;ref name=trois&amp;gt;&amp;lt;pubmed&amp;gt;9455828&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
===Environmental Factors===&lt;br /&gt;
The prevalence of PCOS in populations where there has been a constant gene pool indicates that environmental factors play a significant role in the aetiology of PCOS.&lt;br /&gt;
&lt;br /&gt;
===Obesity and Diet===&lt;br /&gt;
Obesity is the major environmental factor driving the development of PCOS in susceptible individuals. The rising rates of PCOS have been paralleled by the widespread emergence of obesity and type 2 diabetes which are prevalent in developed countries. The risk of developing PCOS from obesity is compounded by  poor dietary choices and lack of physical activity which has begun to characterise the lifestyle in developed countries &amp;lt;ref name=deux/&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
===Medication===&lt;br /&gt;
Studies have shown that valproic acid in medication used to treat epilepsy and bipolar disorders contributes to the development of PCOS. Women with these disorders  may develop the typical features of PCOS such as polycystic ovaries, anovulation, hyperandrogenism and obesity &amp;lt;ref name=quartre&amp;gt;&amp;lt;pubmed&amp;gt;8413434&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Recent studies also suggest that the weight gain from medication is significant as it can lead to the development of PCOS &amp;lt;ref name=deux/&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=Pathogenesis=&lt;br /&gt;
&lt;br /&gt;
The pathogenesis of polycystic ovarian syndrome is poorly understood, however it is believed that insulin resistance and excess androgens such as testosterone play a fundamental role.&lt;br /&gt;
Underlying factors such as obesity and genetic predispositions likely contribute to the onset of polycystic ovarian syndrome through the development of a combination of hyperinsulinemia and hyperandrogenemia.&amp;lt;ref name=eleven&amp;gt;&amp;lt;pubmed&amp;gt;PMC4556908&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
==Hyperinsulinemia==&lt;br /&gt;
&lt;br /&gt;
Hyperinsulinemia is a term that defines the presence of excessive amounts of insulin in the blood relative to the amount of glucose. &amp;lt;ref name=fourteen&amp;gt;&amp;lt;pubmed&amp;gt;PMC4114053&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; This phenomenon is typically associated with obesity and excess adipose tissue, both of which are associated with insulin resistance. In order to overcome this resistance, insulin secretion is increased in an attempt to normalise blood glucose levels, thereby leading to hyperinsulineamia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC2782313&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; Excessive levels of insulin typically cause disruption to the hypothalamus-hypophysis-ovary axis whilst insulin resistance in ovarian tissues leads to decreased metabolic signalling. However, steroidogenic activity is largely unaffected by the impaired metabolic signalling, thereby paving the way androgens to become more effect and paving the way towards hyperandrogenemia. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
[[File:Patholophysiology of Polycystic Ovarian Syndrome.jpg|500px|thumb|left|The impact of hyperinsulinemia and hyperandrogenemia on the development of polycystic ovarian syndrome]]&lt;br /&gt;
&lt;br /&gt;
==Hyperandrogenemia==&lt;br /&gt;
&lt;br /&gt;
Hyperandrogenemia is a hallmark of the development of polycystic ovarian syndrome, with 80% of women presenting with excess androgen also having polycystic ovaries.&amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; The disruption of the hypothalamus hypophysis ovary axis as a result of hyperinsulinemia increases the release of GnRH and LH, leading to increased androgen production in the ovarian theca cells. Hyperandrogenemia decreases the feedback sensitivity of both estradiol and progesterone within gonadotropic hypothalmic cells. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4334071&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; A deficiency of FSH is observed and correlates with the increased secretion of GnRH and LH. As a result of this deficiency, graunlosa  cell aromatisation to oestrogens as well as follicle maturation and ovulation will be drastically impaired.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC3453528&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
As a consequence of the impairment of follicle maturation, small antral follicles will accumulate within the periphery of the ovary and develop a cystic morphology. Ovulation will be unable to occur due to the absence of mature follicles, culminating in infertility.  &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;PMC4562327&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Hyperandrogenism==&lt;br /&gt;
&lt;br /&gt;
===Animal Models===&lt;br /&gt;
&lt;br /&gt;
Studies conducted on female rhesus monkeys have supported evidence for the foetal origins of the clinical features of PCOS &amp;lt;ref name=h1&amp;gt;&amp;lt;pubmed&amp;gt;18406243&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.  It has been shown that in human females, an excess of androgen exposure at any stage from the development of the ovaries to the onset of puberty manifests as characteristic features of PCOS, such as resistance to insulin and Luteinising Hormone (LH) hypersecretion. After exposure to levels of testosterone matching those of fetal males, in utero, female rhesus monkeys were found to display the clinical and biochemical features typical of PCOS such as hypersecretion of LH and abnormal insulin action. These results correlated to those of similar studies conducted on sheep, where the pregnant ewe was exposed to excessive levels of testosterone and LH secretion and abnormality in ovarian cycles were again prominent features &amp;lt;ref name=sheep&amp;gt;Padmanabhan V, Evans NP, Taylor JA, Robinson JE1997 '''Prenatal exposure to  androgens  leads  to  the  development  of  cystic  ovaries  in  the  sheep'''. Biol Reprod 56:194&amp;lt;/ref&amp;gt;. While these studies indicate that similar biochemical and clinical manifestations in humans originate from excess androgen exposure of the female fetus, it must be noted that it is very unlikely for any excess androgen production to be passed across the placenta from the mother to her daughter. This is because mechanisms such as androgen binding proteins and placental metabolism of androgen prevent excess androgen entering the circulation of the fetus &amp;lt;ref name=h2&amp;gt;&amp;lt;pubmed&amp;gt;12098657&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
===Cell Culture Models===&lt;br /&gt;
&lt;br /&gt;
While studies have shown that the adrenal could be a source of excess androgen such as the adrenal &amp;lt;ref name=h3&amp;gt;&amp;lt;pubmed&amp;gt;7962325&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;, they were followed by various studies using cell culture models which demonstrated that the ovary was the major source of excess androgen &amp;lt;ref name=h4/&amp;gt; &amp;lt;ref name=h5&amp;gt;&amp;lt;pubmed&amp;gt;9302378&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. ''In vitro'' studies have shown that the production of steroids is abnormal in theca cells &amp;lt;ref name=h3/&amp;gt;. In women affected by PCOS, stimulation by human chorionic gonadotrophin (hCG) is followed by an increase in thecal steroid production after suppression of LH by a GnRH analogue &amp;lt;ref name=h5/&amp;gt;. Theca cells cultured from polycystic ovaries produce 20 times as much androstenedione as those from normal ovaries &amp;lt;ref name=h4/&amp;gt; with increased expression of mRNA for enzymes responsible for making steroids also reported in following studies. &amp;lt;ref name=h6&amp;gt;&amp;lt;pubmed&amp;gt;10852468&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt; These results have prompted many studies on genes encoding these steroidogeneic enzymes.&lt;br /&gt;
&lt;br /&gt;

===The Genetics of Infertility: Current Status of the Field===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3885174&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article attempted to determine the role that genetics plays in female infertility. It was noted that several prominent causes of female infertility such as Galactosemia and Primary Ovarian Failure (POF) were associated with specific genes, with the GALT gene contributing to the former condition and the FMR1 gene contributing to the latter.&lt;br /&gt;
&lt;br /&gt;
===Causes of Sterility in Bosnia-Herzegovina Population===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC4499307&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
The study conducted as laid out in this article examined the causes of female sterility in the Bosnia-Herzegovina population. Married participants were arranged into various groups based upon their age. The experiment came to the conclusion that in approximately 42% of infertile married couples, female sterility was the primary cause. The two primary causes of female infertility were tubal deficiencies (31% of cases) and Diminished Ovarian Reserves (38% of cases)&lt;br /&gt;
&lt;br /&gt;
===Epidemiology, diagnosis, and management of polycystic ovary syndrome===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This research article examines the causes of polycystic ovary syndrome (POS), a common cause of infertility in women. The article concluded that 50-70% of women suffer from insulin resistance secondary to Type 2 Diabetes and in many cases obseity, which may contribute partially to POS. Furthermore, 85-90% of women with oligomenorrhea also had POS, suggesting that it is an underlying cause. However, the exact pathophysiology of POS was not determined.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Signs and Symptoms=&lt;br /&gt;
&lt;br /&gt;
The symptoms of PCOS are different for each women. The three cardinal signs of PCOS are hyperandrogenism, polycystic ovaries and ovarian dysfunction &amp;lt;ref name=sign1&amp;gt;&amp;lt;pubmed&amp;gt;14688154&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;. Common clinical symptoms include &amp;lt;ref&amp;gt; Women's Heath, U.S. Department of Health and Human Services ,[ http://www.womenshealth.gov/publications/our-publications/fact-sheet/polycystic-ovary-syndrome.html#d ], 'Polycystic ovary syndrome (PCOS) fact sheet'&amp;lt;/ref&amp;gt; ;&lt;br /&gt;
&lt;br /&gt;
- '''Infertility'''- Due to anovulation caused by PCOS. &lt;br /&gt;
- '''Irregular Menstrual Cycles'''&lt;br /&gt;
- '''Hirsutism'''&lt;br /&gt;
- '''Ovarian Cysts'''&lt;br /&gt;
- '''Obesity'''&lt;br /&gt;
- '''Male Pattern Baldness '''&lt;br /&gt;
- '''Skin Tags'''&lt;br /&gt;
- '''Pelvic Pain'''&lt;br /&gt;
&lt;br /&gt;
Along with obesity, PCOS is also associated with other metabolic issues such as insulin resistance, hyperinsulinemia and type 2 diabetes mellitus. It has also been associated with cardiovascular problems and cancers of the breast and endometrium &amp;lt;ref name=sign3&amp;gt;&amp;lt;pubmed&amp;gt;PMC4341818&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Diagnosis=&lt;br /&gt;
&lt;br /&gt;
A major diagnostic tool for PCOS is a pelvic ultrasound, but PCOS diagnosis cannot be completely dependent on just pelvic ultrasounds. A patient with PCOS may not necessarily have polycystic ovaries, and those with ovarian cysts may not necessarily have PCOS. A range of diagnostic assessments and associated symptoms have to be thoroughly investigated&lt;br /&gt;
&lt;br /&gt;
Diagnostic Assessment&lt;br /&gt;
Medical history and examination&lt;br /&gt;
Clinical questions are asked or filled out in the form of a questionnaire to assess and assist in the diagnosis of PCOS. Studies show that those with a history:&lt;br /&gt;
 infrequent and irregular menstruation&lt;br /&gt;
hirsutism (related to high levels of androgens in the blood – hyperandrogenism)&lt;br /&gt;
obesity&lt;br /&gt;
acne production &lt;br /&gt;
are at a higher predictive risk of PCOS. But questions regarding failed pregnancy attempts and history of nipple discharge proved no correlation in diagnosing PCOS. &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/17872783 &amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Blood Test&lt;br /&gt;
A patient with elevated levels of androgens, hyperandrogenism, is very highly likely to have PCOS. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/20591140 &amp;lt;/ref&amp;gt;&lt;br /&gt;
Androgens, such as testosterone, and free androgen index (FAI) are the two tests best used in diagnosing hyperandrogenism.&lt;br /&gt;
Androgen excess in PCOS is a result from increased synthesis and release of ovarian androgens. Dehydroepiandrosterone sulfate (DHEA-S) levels are used as a biomarker for testing androgen levels, as it is made exclusively by the adrenal glands. DHEA-S levels of above 1890 micromol/L is extremely suggestive of hyperandrogenism. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/18844715 &amp;lt;/ref&amp;gt;&lt;br /&gt;
Free androgen index (FAI) is the ratio of total testosterone measurement to levels of sex hormone-binding globulin (SHBG). Those with PCOS will have high FAI, as this indicates a high ration of free testosterone in the body.&lt;br /&gt;
Other blood tests are also done to help exclude other predisposing factors such as levels of Thyroid Stimulating Hormone (LSH) and Follicle-stimulating hormone (FSH). An elevated ratio of LSH to FSH, of above 2:1 &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/14737959 &amp;lt;/ref&amp;gt;, indicates a possibility, but not definitively, of PCOS.&lt;br /&gt;
The effect of insulin on blood can also be tested for insulin resistance. Insulin resistance augments androgen production and increases free androgen levels by reducing SHBG. This can used as an indication marker for the possibility of PCOS&lt;br /&gt;
A study in 2014 showed that Anti-Müllerian hormone (AMH) is found to be elevated in patients with PCOS &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24821925 &amp;lt;/ref&amp;gt;, giving rise to its potential clinical implication in diagnosing PCOS. AMH is exclusively produced in ovarian follicles, with individual AMH concentration reflecting the quantity of remaining primordial follicles and measure of ovarian reserve. &lt;br /&gt;
&lt;br /&gt;
Gynecologic ultrasonography&lt;br /&gt;
Gynecologic ultrasonography is a pelvic ultrasound, specifically to the female pelvic region, with regards to the uterus, ovaries and the fallopian tube. The examination can be performed by transabdominal ultrasonography, with a full bladder, or transvaginal ultrasonography with a vaginal transducer. Typically transvaginal imaging shows a better and clearer image than transabdominal ultrasonography, as it uses higher frequency imaging, but is limited to areas it can reach. In the case of PCOS, both techniques can provide an image of the ovaries. Studies suggest that if more than 25 follicles are seen in an ovary, predominantly in the periphery, in women between 18-35 years, it is described to have a polycystic ovarian morphology. &amp;lt;ref&amp;gt; https://www.ncbi.nlm.nih.gov/pubmed/24345633 &amp;lt;/ref&amp;gt;&lt;br /&gt;
Magnetic Resonance Imaging&lt;br /&gt;
Ovaries can also be seen on MRIs. On MRIs, PCOS is characterized by numberous peripheral cysts where the ovaries affected to be slightly larger than normal. Although MRI is seen to be effective in ovarian imaging, the finding of peripheral ovarian cysts in MRIsmay not be PCOS specific. &amp;lt;ref&amp;gt;  http://www.ncbi.nlm.nih.gov/pubmed/8888256 &amp;lt;/ref&amp;gt; But studies have seen that MR imaging in adolescence uncover distinct differences between young patients with and without PCOS &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/23292744 &amp;lt;/ref&amp;gt;, with also great diagnostic sensitivity with patients between the age of 21-30 &amp;lt;ref&amp;gt; http://www.ncbi.nlm.nih.gov/pubmed/19241321 &amp;lt;/ref&amp;gt;, providing assistance of imagery in patients whom may be opposed to transvaginal ultrasounds.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Prevention=&lt;br /&gt;
&lt;br /&gt;
==Impact of physical activity on ovarian reserve markers in normal, overweight and obese reproductive age women==&lt;br /&gt;
&amp;lt;pubmed&amp;gt;25509968&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study focuses on the effect of physical activity on fertility in three groups of women at reproductive age; normal, overweight and obese. The results from the study suggest that there was a marked improvement in fertility as shown by the ovarian reserve markers for all 3 groups, however it was most significant in the overweight and obese groups. This study is relevant to our project as it gives an insight into the preventative measures that can be taken for infertility. &lt;br /&gt;
&lt;br /&gt;
==Risk factors of polycystic ovarian syndrome among Li People==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;26276294&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study examined the risk factors entailed in Polycystic Ovarian Syndrdome (PCOS) amoung Li people. Using the method of a case control study, questionnaires were given to female Li people with and without PCOS. Analysis of the questionnaires showed that family history of diabetes, family history of infertility, bad mood, lack of physical exercise are all high risk factors of PCOS. As a result, management of these risk factors can be taken into consideration when preventing infertility through PCOS.&lt;br /&gt;
&lt;br /&gt;
==Vitamin D and female fertility==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;24717915&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article is a review focusing on research regarding Vitamin D and fertility over the past year. The review found that the levels of Vitamin D is crucial for women undergoing in-vitro fertilisation. It  was also found that Vitamin D was beneficial for women with PCOS and carried a protective effect against endometriosis. These observations suggest that having sufficient Vitamin D in your body can be preventative for problems associated with fertility.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=Treatment=&lt;br /&gt;
&lt;br /&gt;
===Current Treatments===&lt;br /&gt;
&lt;br /&gt;
{|border=&amp;quot;1&amp;quot;&lt;br /&gt;
|-bgcolor=&amp;quot;DDCEF2&amp;quot;&lt;br /&gt;
| '''CURRENT TREATMENT'''&lt;br /&gt;
| '''DISADVANTAGES'''&lt;br /&gt;
|-&lt;br /&gt;
| General Practitioners tend to prescribe oral anti-oestrogens, most commonly the contraceptive pill, to restore ovulation.&lt;br /&gt;
| This method only has a 50% success rate in PCOS patients. It does not directly increase fertility rates, but restores the menstrual cycle.&lt;br /&gt;
 &lt;br /&gt;
|-bgcolor=&amp;quot;FAF5FF&amp;quot;&lt;br /&gt;
| Lifestyle changes are highly encouraged by medical practitioners. Diet and exercise regimes can be designed with a dietitian or nutritionist. &lt;br /&gt;
| Exercise and diet plans do not directly increase fertility. They are designed to enhance weight loss, which in some patients can encourage normal hormone levels from the pituitary and thyroid. &lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| Clomiphene citrate administration (generally in pill form, as prescribed by a GP). Such pills stimulate the pituitary gland to release GnRH to simulate ovulation (with a 72% success rate in the ___ trial). &lt;br /&gt;
| Clomiphene can cause multiple side effects, most notably abnormal uterine bleeding and pelvic pain to due enlargement of the ovaries. &lt;br /&gt;
&lt;br /&gt;
Thus, it cannot be as frequently prescribed as the contraceptive pill, and careful patient monitoring is imperative. &lt;br /&gt;
&lt;br /&gt;
|-bgcolor=&amp;quot;FAF5FF&amp;quot;&lt;br /&gt;
| Higher fertility rates are observed in treatments combining clomiphene citrate and metformin (79% success).&lt;br /&gt;
| Similar disadvantages as clomiphene, above.&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
===New Trials===&lt;br /&gt;
&lt;br /&gt;
Some studies have found that regular Selenium supplements can encourage fertility among PCOS patients. The program, which is still in its early trial period, requires women to consume selenium tablets for 8 weeks. This study has found a significant decrease in dehydroepiandrosterone (DHEA) levels in patients, thus reducing excessive hair growth associated with PCOS. A direct link to increased fertility is yet to be established, and thus further testing is required.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
Heat stress has previously seen a decrease in fertility in dairy cows, whilst similarly, pregnancy rates in women are recorded to be lowest during the summer season, paving way for the postulation that fertilization may be disrupted due to elevated temperatures. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
3 different experiments were performed to determine the underlying mechanism causing the disruption to fertilization due to increase in temperature. Oocytes and Spermatozoa were exposed to physiological temperatures that mirrored those of mammalian organisms. Oocytes were fertilized at 38.5-41ºC with either no-pre-incubated sperm or 38.5 / 41ºC incubated sperm, to investigate the effected on sperm plasma membrane, viability, and penetration, polyspermy, subsequent development of zygote, and embryonic competence. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
The results showed that at elevated temperatures, percentage of motile sperm were reduced, along with altered transcription due to oxidative stress, resulting in an increase in polyspermy. In addition, the zona pellucida of zygotes was sensitive to pronase digestion during heat stress, and exhibited decreased transcription of gene UCHL1, which played the role of preventing polyspermy. Rates of cell cleave and blastocysts formation were also seen to have reduced. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
Because of the results shown, this study reports that the increase in polyspermy is the most likely cause of the reduced blastocyst formation due to the reduced capability of zygotes at elevated temperatures to develop to the next stage. (Sakatani et all, 2014)&lt;br /&gt;

&lt;br /&gt;
Cyclophosphamide is an alkylating agent most commonly used to treat cancers with other chemotherapy agents. It’s used to quickly control cancerous diseases but is highly toxic. Sperm banking in those prior to cancer treatment have seen to have more effective Intracytoplasmic Sperm Injection in In Vitro Fertilization compared to those performing IVF/ICSI after their first dose of chemotherapy. This study tests whether there is correlation between the agent, Cyclophosphamide, and the reduced preimplantation embryo development, birth rate, and genetic integrity of embryos after embryo transfer. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Untreated sperm of adult male B6D2 mice were first collected. They were then administered cyclophosphamide after seven days, and were sacrificed to obtain the treated sperm. Oocytes were collected after controlled ovarian stimulation. Half the oocytes from each female were exposed with Cyclophosphamide exposed sperm and untreated sperm from the same male mice. Embryos were monitored in vitro for 2 days and were then collected for exome sequencing. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Results showed that the average percentage of oocyte survival was 94.8%, whereas for embryos treated with Cyclophosphamide, percentage of survival was significantly lowered to 49%. Birth rates after embryo transfer showed no difference between the two groups but Cyclophosphamide-treated group had lower litter size (0.8 vs 3.8) and pups per embryo transferred (2.7% vs. 14%). (Johnson et all, 2015)&lt;br /&gt;
This study argues that Cyclophosphamide exposed sperm decreased development in embryo, resulting in lowered numbers of offspring and lower number of offspring survival. Further investigation is needed in order to know the reason and mechanism behind Cyclophosphamide’s influence on male sperm and fertilization. (Johnson et all, 2015)&lt;br /&gt;

===Female Infertility : Diagnosis===&lt;br /&gt;

&lt;br /&gt;
MR imaging has extended its use to evaluating and diagnosing disorders related to female infertility, including ovulatory, fallopian tube, and uterine disorders, and also pelvic enometiosis. It is used in a variety of clinical settings by providing a clear vizualization of the pelvic region and is now useful in conjunction with other diagnostic techniques like laparoscopy, hysteroscopy, and hysterosalpinogography.&lt;br /&gt;

====Comparison of diagnostic accuracy of laparoscopy, hysteroscopy, and hysterosalpingography in evaluation of female infertility. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;6232154 &amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;====&lt;br /&gt;
In a group of 77 women evaluated, Laparoscopy confirmed 84% evidence of tubal disease and hysteroscopy confirmed 69% radiographic evidence of intrauterine abnormalities. IN contrast HS gave a false-positive rate of 16% and 31% respectively. Data suggests that laparoscopy is best detecting previously unsuspected tubal disease, and hysteroscopy with information of managing abnormalities. But for optimum evaluation, a combined approach of all three procedures is best.&lt;br /&gt;

Earlier assessment is best in women who have history of oligomenorrhea/amenorrhea, with key objective of assessment and diagnosis to rule out azoospermia, anovulation, or tubal obstruction.&lt;br /&gt;
In order to do so an assesment of ovulatory function, uterine cavity, and tubal patency by HSG/laparoscopyis needed.&lt;br /&gt;
Assessments like post coital tests, endometrial biopsies, and basal bdy temperature records are no longer a routine investigation.&lt;br /&gt;

&lt;br /&gt;
Cyclophosphamide is an alkylating agent most commonly used to treat cancers with other chemotherapy agents. It’s used to quickly control cancerous diseases but is highly toxic. Sperm banking in those prior to cancer treatment have seen to have more effective Intracytoplasmic Sperm Injection in In Vitro Fertilization compared to those performing IVF/ICSI after their first dose of chemotherapy. This study tests whether there is correlation between the agent, Cyclophosphamide, and the reduced preimplantation embryo development, birth rate, and genetic integrity of embryos after embryo transfer. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Untreated sperm of adult male B6D2 mice were first collected. They were then administered cyclophosphamide after seven days, and were sacrificed to obtain the treated sperm. Oocytes were collected after controlled ovarian stimulation. Half the oocytes from each female were exposed with Cyclophosphamide exposed sperm and untreated sperm from the same male mice. Embryos were monitored in vitro for 2 days and were then collected for exome sequencing. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Results showed that the average percentage of oocyte survival was 94.8%, whereas for embryos treated with Cyclophosphamide, percentage of survival was significantly lowered to 49%. Birth rates after embryo transfer showed no difference between the two groups but Cyclophosphamide-treated group had lower litter size (0.8 vs 3.8) and pups per embryo transferred (2.7% vs. 14%). (Johnson et all, 2015)&lt;br /&gt;
This study argues that Cyclophosphamide exposed sperm decreased development in embryo, resulting in lowered numbers of offspring and lower number of offspring survival. Further investigation is needed in order to know the reason and mechanism behind Cyclophosphamide’s influence on male sperm and fertilization. (Johnson et all, 2015)&lt;br /&gt;

Earlier assessment is best in women who have history of oligomenorrhea/amenorrhea, with key objective of assessment and diagnosis to rule out azoospermia, anovulation, or tubal obstruction.&lt;br /&gt;
In order to do so an assesment of ovulatory function, uterine cavity, and tubal patency by HSG/laparoscopyis needed.&lt;br /&gt;
Assessments like post coital tests, endometrial biopsies, and basal bdy temperature records are no longer a routine investigation.&lt;br /&gt;

&lt;br /&gt;
Heat stress has previously seen a decrease in fertility in dairy cows, whilst similarly, pregnancy rates in women are recorded to be lowest during the summer season, paving way for the postulation that fertilization may be disrupted due to elevated temperatures. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
3 different experiments were performed to determine the underlying mechanism causing the disruption to fertilization due to increase in temperature. Oocytes and Spermatozoa were exposed to physiological temperatures that mirrored those of mammalian organisms. Oocytes were fertilized at 38.5-41ºC with either no-pre-incubated sperm or 38.5 / 41ºC incubated sperm, to investigate the effected on sperm plasma membrane, viability, and penetration, polyspermy, subsequent development of zygote, and embryonic competence. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
The results showed that at elevated temperatures, percentage of motile sperm were reduced, along with altered transcription due to oxidative stress, resulting in an increase in polyspermy. In addition, the zona pellucida of zygotes was sensitive to pronase digestion during heat stress, and exhibited decreased transcription of gene UCHL1, which played the role of preventing polyspermy. Rates of cell cleave and blastocysts formation were also seen to have reduced. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
Because of the results shown, this study reports that the increase in polyspermy is the most likely cause of the reduced blastocyst formation due to the reduced capability of zygotes at elevated temperatures to develop to the next stage. (Sakatani et all, 2014)&lt;br /&gt;

&lt;br /&gt;
Cyclophosphamide is an alkylating agent most commonly used to treat cancers with other chemotherapy agents. It’s used to quickly control cancerous diseases but is highly toxic. Sperm banking in those prior to cancer treatment have seen to have more effective Intracytoplasmic Sperm Injection in In Vitro Fertilization compared to those performing IVF/ICSI after their first dose of chemotherapy. This study tests whether there is correlation between the agent, Cyclophosphamide, and the reduced preimplantation embryo development, birth rate, and genetic integrity of embryos after embryo transfer. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Untreated sperm of adult male B6D2 mice were first collected. They were then administered cyclophosphamide after seven days, and were sacrificed to obtain the treated sperm. Oocytes were collected after controlled ovarian stimulation. Half the oocytes from each female were exposed with Cyclophosphamide exposed sperm and untreated sperm from the same male mice. Embryos were monitored in vitro for 2 days and were then collected for exome sequencing. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Results showed that the average percentage of oocyte survival was 94.8%, whereas for embryos treated with Cyclophosphamide, percentage of survival was significantly lowered to 49%. Birth rates after embryo transfer showed no difference between the two groups but Cyclophosphamide-treated group had lower litter size (0.8 vs 3.8) and pups per embryo transferred (2.7% vs. 14%). (Johnson et all, 2015)&lt;br /&gt;
This study argues that Cyclophosphamide exposed sperm decreased development in embryo, resulting in lowered numbers of offspring and lower number of offspring survival. Further investigation is needed in order to know the reason and mechanism behind Cyclophosphamide’s influence on male sperm and fertilization. (Johnson et all, 2015)&lt;br /&gt;

&lt;br /&gt;
MR imaging has extended its use to evaluating and diagnosing disorders related to female infertility, including ovulatory, fallopian tube, and uterine disorders, and also pelvic enometiosis. It is used in a variety of clinical settings by providing a clear vizualization of the pelvic region and is now useful in conjunction with other diagnostic techniques like laparoscopy, hysteroscopy, and hysterosalpinogography.&lt;br /&gt;

In a group of 77 women evaluated, Laparoscopy confirmed 84% evidence of tubal disease and hysteroscopy confirmed 69% radiographic evidence of intrauterine abnormalities. IN contrast HS gave a false-positive rate of 16% and 31% respectively. Data suggests that laparoscopy is best detecting previously unsuspected tubal disease, and hysteroscopy with information of managing abnormalities. But for optimum evaluation, a combined approach of all three procedures is best.&lt;br /&gt;

&lt;br /&gt;
Cyclophosphamide is an alkylating agent most commonly used to treat cancers with other chemotherapy agents. It’s used to quickly control cancerous diseases but is highly toxic. Sperm banking in those prior to cancer treatment have seen to have more effective Intracytoplasmic Sperm Injection in In Vitro Fertilization compared to those performing IVF/ICSI after their first dose of chemotherapy. This study tests whether there is correlation between the agent, Cyclophosphamide, and the reduced preimplantation embryo development, birth rate, and genetic integrity of embryos after embryo transfer. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Untreated sperm of adult male B6D2 mice were first collected. They were then administered cyclophosphamide after seven days, and were sacrificed to obtain the treated sperm. Oocytes were collected after controlled ovarian stimulation. Half the oocytes from each female were exposed with Cyclophosphamide exposed sperm and untreated sperm from the same male mice. Embryos were monitored in vitro for 2 days and were then collected for exome sequencing. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Results showed that the average percentage of oocyte survival was 94.8%, whereas for embryos treated with Cyclophosphamide, percentage of survival was significantly lowered to 49%. Birth rates after embryo transfer showed no difference between the two groups but Cyclophosphamide-treated group had lower litter size (0.8 vs 3.8) and pups per embryo transferred (2.7% vs. 14%). (Johnson et all, 2015)&lt;br /&gt;
This study argues that Cyclophosphamide exposed sperm decreased development in embryo, resulting in lowered numbers of offspring and lower number of offspring survival. Further investigation is needed in order to know the reason and mechanism behind Cyclophosphamide’s influence on male sperm and fertilization. (Johnson et all, 2015)&lt;br /&gt;

&lt;br /&gt;
MR imaging has extended its use to evaluating and diagnosing disorders related to female infertility, including ovulatory, fallopian tube, and uterine disorders, and also pelvic enometiosis. It is used in a variety of clinical settings by providing a clear vizualization of the pelvic region and is now useful in conjunction with other diagnostic techniques like laparoscopy, hysteroscopy, and hysterosalpinogography.&lt;br /&gt;

In a group of 77 women evaluated, Laparoscopy confirmed 84% evidence of tubal disease and hysteroscopy confirmed 69% radiographic evidence of intrauterine abnormalities. IN contrast HS gave a false-positive rate of 16% and 31% respectively. Data suggests that laparoscopy is best detecting previously unsuspected tubal disease, and hysteroscopy with information of managing abnormalities. But for optimum evaluation, a combined approach of all three procedures is best.&lt;br /&gt;

Earlier assessment is best in women who have history of oligomenorrhea/amenorrhea, with key objective of assessment and diagnosis to rule out azoospermia, anovulation, or tubal obstruction.&lt;br /&gt;
In order to do so an assesment of ovulatory function, uterine cavity, and tubal patency by HSG/laparoscopyis needed.&lt;br /&gt;
Assessments like post coital tests, endometrial biopsies, and basal bdy temperature records are no longer a routine investigation.&lt;br /&gt;

&lt;br /&gt;
Heat stress has previously seen a decrease in fertility in dairy cows, whilst similarly, pregnancy rates in women are recorded to be lowest during the summer season, paving way for the postulation that fertilization may be disrupted due to elevated temperatures. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
3 different experiments were performed to determine the underlying mechanism causing the disruption to fertilization due to increase in temperature. Oocytes and Spermatozoa were exposed to physiological temperatures that mirrored those of mammalian organisms. Oocytes were fertilized at 38.5-41ºC with either no-pre-incubated sperm or 38.5 / 41ºC incubated sperm, to investigate the effected on sperm plasma membrane, viability, and penetration, polyspermy, subsequent development of zygote, and embryonic competence. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
The results showed that at elevated temperatures, percentage of motile sperm were reduced, along with altered transcription due to oxidative stress, resulting in an increase in polyspermy. In addition, the zona pellucida of zygotes was sensitive to pronase digestion during heat stress, and exhibited decreased transcription of gene UCHL1, which played the role of preventing polyspermy. Rates of cell cleave and blastocysts formation were also seen to have reduced. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
Because of the results shown, this study reports that the increase in polyspermy is the most likely cause of the reduced blastocyst formation due to the reduced capability of zygotes at elevated temperatures to develop to the next stage. (Sakatani et all, 2014)&lt;br /&gt;

Cyclophosphamide is an alkylating agent most commonly used to treat cancers with other chemotherapy agents. It’s used to quickly control cancerous diseases but is highly toxic. Sperm banking in those prior to cancer treatment have seen to have more effective Intracytoplasmic Sperm Injection in In Vitro Fertilization compared to those performing IVF/ICSI after their first dose of chemotherapy. This study tests whether there is correlation between the agent, Cyclophosphamide, and the reduced preimplantation embryo development, birth rate, and genetic integrity of embryos after embryo transfer. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Untreated sperm of adult male B6D2 mice were first collected. They were then administered cyclophosphamide after seven days, and were sacrificed to obtain the treated sperm. Oocytes were collected after controlled ovarian stimulation. Half the oocytes from each female were exposed with Cyclophosphamide exposed sperm and untreated sperm from the same male mice. Embryos were monitored in vitro for 2 days and were then collected for exome sequencing. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Results showed that the average percentage of oocyte survival was 94.8%, whereas for embryos treated with Cyclophosphamide, percentage of survival was significantly lowered to 49%. Birth rates after embryo transfer showed no difference between the two groups but Cyclophosphamide-treated group had lower litter size (0.8 vs 3.8) and pups per embryo transferred (2.7% vs. 14%). (Johnson et all, 2015)&lt;br /&gt;
This study argues that Cyclophosphamide exposed sperm decreased development in embryo, resulting in lowered numbers of offspring and lower number of offspring survival. Further investigation is needed in order to know the reason and mechanism behind Cyclophosphamide’s influence on male sperm and fertilization. (Johnson et all, 2015)&lt;br /&gt;

Heat stress has previously seen a decrease in fertility in dairy cows, whilst similarly, pregnancy rates in women are recorded to be lowest during the summer season, paving way for the postulation that fertilization may be disrupted due to elevated temperatures. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
3 different experiments were performed to determine the underlying mechanism causing the disruption to fertilization due to increase in temperature. Oocytes and Spermatozoa were exposed to physiological temperatures that mirrored those of mammalian organisms. Oocytes were fertilized at 38.5-41ºC with either no-pre-incubated sperm or 38.5 / 41ºC incubated sperm, to investigate the effected on sperm plasma membrane, viability, and penetration, polyspermy, subsequent development of zygote, and embryonic competence. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
The results showed that at elevated temperatures, percentage of motile sperm were reduced, along with altered transcription due to oxidative stress, resulting in an increase in polyspermy. In addition, the zona pellucida of zygotes was sensitive to pronase digestion during heat stress, and exhibited decreased transcription of gene UCHL1, which played the role of preventing polyspermy. Rates of cell cleave and blastocysts formation were also seen to have reduced. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
Because of the results shown, this study reports that the increase in polyspermy is the most likely cause of the reduced blastocyst formation due to the reduced capability of zygotes at elevated temperatures to develop to the next stage. (Sakatani et all, 2014)&lt;br /&gt;

Cyclophosphamide is an alkylating agent most commonly used to treat cancers with other chemotherapy agents. It’s used to quickly control cancerous diseases but is highly toxic. Sperm banking in those prior to cancer treatment have seen to have more effective Intracytoplasmic Sperm Injection in In Vitro Fertilization compared to those performing IVF/ICSI after their first dose of chemotherapy. This study tests whether there is correlation between the agent, Cyclophosphamide, and the reduced preimplantation embryo development, birth rate, and genetic integrity of embryos after embryo transfer. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Untreated sperm of adult male B6D2 mice were first collected. They were then administered cyclophosphamide after seven days, and were sacrificed to obtain the treated sperm. Oocytes were collected after controlled ovarian stimulation. Half the oocytes from each female were exposed with Cyclophosphamide exposed sperm and untreated sperm from the same male mice. Embryos were monitored in vitro for 2 days and were then collected for exome sequencing. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Results showed that the average percentage of oocyte survival was 94.8%, whereas for embryos treated with Cyclophosphamide, percentage of survival was significantly lowered to 49%. Birth rates after embryo transfer showed no difference between the two groups but Cyclophosphamide-treated group had lower litter size (0.8 vs 3.8) and pups per embryo transferred (2.7% vs. 14%). (Johnson et all, 2015)&lt;br /&gt;
This study argues that Cyclophosphamide exposed sperm decreased development in embryo, resulting in lowered numbers of offspring and lower number of offspring survival. Further investigation is needed in order to know the reason and mechanism behind Cyclophosphamide’s influence on male sperm and fertilization. (Johnson et all, 2015)&lt;br /&gt;

&lt;br /&gt;
Heat stress has previously seen a decrease in fertility in dairy cows, whilst similarly, pregnancy rates in women are recorded to be lowest during the summer season, paving way for the postulation that fertilization may be disrupted due to elevated temperatures. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
3 different experiments were performed to determine the underlying mechanism causing the disruption to fertilization due to increase in temperature. Oocytes and Spermatozoa were exposed to physiological temperatures that mirrored those of mammalian organisms. Oocytes were fertilized at 38.5-41ºC with either no-pre-incubated sperm or 38.5 / 41ºC incubated sperm, to investigate the effected on sperm plasma membrane, viability, and penetration, polyspermy, subsequent development of zygote, and embryonic competence. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
The results showed that at elevated temperatures, percentage of motile sperm were reduced, along with altered transcription due to oxidative stress, resulting in an increase in polyspermy. In addition, the zona pellucida of zygotes was sensitive to pronase digestion during heat stress, and exhibited decreased transcription of gene UCHL1, which played the role of preventing polyspermy. Rates of cell cleave and blastocysts formation were also seen to have reduced. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
Because of the results shown, this study reports that the increase in polyspermy is the most likely cause of the reduced blastocyst formation due to the reduced capability of zygotes at elevated temperatures to develop to the next stage. (Sakatani et all, 2014)&lt;br /&gt;

&lt;br /&gt;
Cyclophosphamide is an alkylating agent most commonly used to treat cancers with other chemotherapy agents. It’s used to quickly control cancerous diseases but is highly toxic. Sperm banking in those prior to cancer treatment have seen to have more effective Intracytoplasmic Sperm Injection in In Vitro Fertilization compared to those performing IVF/ICSI after their first dose of chemotherapy. This study tests whether there is correlation between the agent, Cyclophosphamide, and the reduced preimplantation embryo development, birth rate, and genetic integrity of embryos after embryo transfer. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Untreated sperm of adult male B6D2 mice were first collected. They were then administered cyclophosphamide after seven days, and were sacrificed to obtain the treated sperm. Oocytes were collected after controlled ovarian stimulation. Half the oocytes from each female were exposed with Cyclophosphamide exposed sperm and untreated sperm from the same male mice. Embryos were monitored in vitro for 2 days and were then collected for exome sequencing. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Results showed that the average percentage of oocyte survival was 94.8%, whereas for embryos treated with Cyclophosphamide, percentage of survival was significantly lowered to 49%. Birth rates after embryo transfer showed no difference between the two groups but Cyclophosphamide-treated group had lower litter size (0.8 vs 3.8) and pups per embryo transferred (2.7% vs. 14%). (Johnson et all, 2015)&lt;br /&gt;
This study argues that Cyclophosphamide exposed sperm decreased development in embryo, resulting in lowered numbers of offspring and lower number of offspring survival. Further investigation is needed in order to know the reason and mechanism behind Cyclophosphamide’s influence on male sperm and fertilization. (Johnson et all, 2015)&lt;br /&gt;

===Female Infertility : Diagnosis===&lt;br /&gt;

&lt;br /&gt;
MR imaging has extended its use to evaluating and diagnosing disorders related to female infertility, including ovulatory, fallopian tube, and uterine disorders, and also pelvic enometiosis. It is used in a variety of clinical settings by providing a clear vizualization of the pelvic region and is now useful in conjunction with other diagnostic techniques like laparoscopy, hysteroscopy, and hysterosalpinogography.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;i&amp;gt; PMID 14615553 &amp;lt;/i&amp;gt;&lt;br /&gt;

====Comparison of diagnostic accuracy of laparoscopy, hysteroscopy, and hysterosalpingography in evaluation of female infertility. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;6232154 &amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;====&lt;br /&gt;
In a group of 77 women evaluated, Laparoscopy confirmed 84% evidence of tubal disease and hysteroscopy confirmed 69% radiographic evidence of intrauterine abnormalities. IN contrast HS gave a false-positive rate of 16% and 31% respectively. Data suggests that laparoscopy is best detecting previously unsuspected tubal disease, and hysteroscopy with information of managing abnormalities. But for optimum evaluation, a combined approach of all three procedures is best.&lt;br /&gt;

====Diagnosis and Management of Female Infertility. &amp;lt;ref&amp;gt;&amp;lt;pubmed&amp;gt;14519712&amp;lt;/pubmed&amp;gt;&amp;lt;/ref&amp;gt;====&lt;br /&gt;
Earlier assessment is best in women who have history of oligomenorrhea/amenorrhea, with key objective of assessment and diagnosis to rule out azoospermia, anovulation, or tubal obstruction.&lt;br /&gt;
In order to do so an assesment of ovulatory function, uterine cavity, and tubal patency by HSG/laparoscopyis needed.&lt;br /&gt;
Assessments like post coital tests, endometrial biopsies, and basal bdy temperature records are no longer a routine investigation.&lt;br /&gt;

MR imaging has extended its use to evaluating and diagnosing disorders related to female infertility, including ovulatory, fallopian tube, and uterine disorders, and also pelvic enometiosis. It is used in a variety of clinical settings by providing a clear vizualization of the pelvic region and is now useful in conjunction with other diagnostic techniques like laparoscopy, hysteroscopy, and hysterosalpinogography.&lt;br /&gt;

In a group of 77 women evaluated, Laparoscopy confirmed 84% evidence of tubal disease and hysteroscopy confirmed 69% radiographic evidence of intrauterine abnormalities. IN contrast HS gave a false-positive rate of 16% and 31% respectively. Data suggests that laparoscopy is best detecting previously unsuspected tubal disease, and hysteroscopy with information of managing abnormalities. But for optimum evaluation, a combined approach of all three procedures is best.&lt;br /&gt;

&lt;div&gt;=FEMALE INFERTILITY: ''Definition''=&lt;br /&gt;
&lt;br /&gt;
&amp;quot;Infertility is defined as inability of couple to conceive after one year of unprotected intercourse.Various factors and conditions can contribute to female infertility, some of which are still unknown.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
'''''Adapted from''''' &amp;lt;pubmed&amp;gt;26150870&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
==Causes==&lt;br /&gt;
===The Genetics of Infertility: Current Status of the Field===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3885174&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article attempted to determine the role that genetics plays in female infertility. It was noted that several prominent causes of female infertility such as Galactosemia and Primary Ovarian Failure (POF) were associated with specific genes, with the GALT gene contributing to the former condition and the FMR1 gene contributing to the latter.&lt;br /&gt;
&lt;br /&gt;
===Causes of Sterility in Bosnia-Herzegovina Population===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC4499307&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
The study conducted as laid out in this article examined the causes of female sterility in the Bosnia-Herzegovina population. Married participants were arranged into various groups based upon their age. The experiment came to the conclusion that in approximately 42% of infertile married couples, female sterility was the primary cause. The two primary causes of female infertility were tubal deficiencies (31% of cases) and Diminished Ovarian Reserves (38% of cases)&lt;br /&gt;
&lt;br /&gt;
===Epidemiology, diagnosis, and management of polycystic ovary syndrome===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This research article examines the causes of polycystic ovary syndrome (POS), a common cause of infertility in women. The article concluded that 50-70% of women suffer from insulin resistance secondary to Type 2 Diabetes and in many cases obseity, which may contribute partially to POS. Furthermore, 85-90% of women with oligomenorrhea also had POS, suggesting that it is an underlying cause. However, the exact pathophysiology of POS was not determined.&lt;br /&gt;

&lt;br /&gt;
===Impact of physical activity on ovarian reserve markers in normal, overweight and obese reproductive age women===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;25509968&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study focuses on the effect of physical activity on fertility in three groups of women at reproductive age; normal, overweight and obese. The results from the study suggest that there was a marked improvement in fertility as shown by the ovarian reserve markers for all 3 groups, however it was most significant in the overweight and obese groups. This study is relevant to our project as it gives an insight into the preventative measures that can be taken for infertility. &lt;br /&gt;
&lt;br /&gt;
===Risk factors of polycystic ovarian syndrome among Li People ===&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;26276294&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study examined the risk factors entailed in Polycystic Ovarian Syndrdome (PCOS) amoung Li people. Using the method of a case control study, questionnaires were given to female Li people with and without PCOS. Analysis of the questionnaires showed that family history of diabetes, family history of infertility, bad mood, lack of physical exercise are all high risk factors of PCOS. As a result, management of these risk factors can be taken into consideration when preventing infertility through PCOS.&lt;br /&gt;
&lt;br /&gt;
===Vitamin D and female fertility===&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;24717915&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article is a review focusing on research regarding Vitamin D and fertility over the past year. The review found that the levels of Vitamin D is crucial for women undergoing in-vitro fertilisation. It  was also found that Vitamin D was beneficial for women with PCOS and carried a protective effect against endometriosis. These observations suggest that having sufficient Vitamin D in your body can be preventative for problems associated with fertility.&lt;br /&gt;
&lt;br /&gt;
==Treatment==&lt;br /&gt;
&lt;br /&gt;
'''''The Effect of a Complex Multi-modality Ayurvedic Treatment in a Case of Unknown Female Infertility'''''&lt;br /&gt;
&lt;br /&gt;
This article documented a 38 year old woman's journey to giving birth, after she was advised that she was infertile (of unknown cause). The researchers detail the various modern day medical treatments she underwent to become pregnant, all of which were unsuccessful. She then decided to try holistic medicine in the form of Ayurvedic treatment, which consisted of meditation, a controlled diet and yoga. To the researchers' surprise, she became pregnant soon after, and gave birth to a healthy baby boy in 2012. The study comes to the conclusion that Ayurvedic medicine and successful birth rates do not show a strong correlation, and thus should not be favoured over standard medical treatments. However, they did state that holistic medicine could improve the overall wellbeing of the mother (in terms of stress and diet), which in turn increases the chances of becoming pregnant.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

'''''Pregnancy Rate after Controlled Ovarian Hyperstimulation and Intrauterine Insemination for the Treatment of Endometriosis following Surgery'''''&lt;br /&gt;
&lt;br /&gt;
This study investigated various treatments available for women with endometriosis, and the rate of successful pregnancies and births in patients following their treatment. The researchers came to the conclusion that a woman's chances of becoming pregnant increased following laparoscopic surgery, particularly in the first six months following the procedure. If pregnancy does not occur, controlled ovarian hyperstimulation and intrauterine insemination (COH-IU) should be the next option, due to its success rates. &lt;br /&gt;
  &lt;br /&gt;

&lt;br /&gt;
'''''Time-limited Hydrotubation Combined with Clomiphene Citrate Treatment for Unexplained Infertility'''''&lt;br /&gt;
&lt;br /&gt;
In this experiment, 80 random patients with &amp;quot;unexplained inferility&amp;quot; were selected and treated with hydotrubation and clomiphene citrate (CC). Of the 80 patients, 15 became pregnant, with the researchers concluding that combined hydrotubation and CC treatment increased a woman's chance of becoming pregnant to a greater degree than just CC alone. Further tests need to be completed to strengthen the correlation between the treatment and outcome.&lt;br /&gt;

&lt;br /&gt;
'''''Frequency and Outcome of Treatment in Polycystic Ovaries Related Infertility'''''&lt;br /&gt;
&lt;br /&gt;
This study examined treatments available to women with Polycystic Ovarian Syndrome (PCOS). It came to the conclusion that in overweight women with PCOS, weight loss, exercise and better lifestyle choices are the best treatments as they significantly increases pregnancy rates. Furthermore, clomiphene citrate (CC) and metformine combined treatments are highly effective in PCOS women, and should be one of the first options offered to a patient. &lt;br /&gt;

DOI 10.1002/mrd.22441. http://onlinelibrary.wiley.com/doi/10.1002/mrd.22441/pdf &amp;lt;/ref&amp;gt;&lt;br /&gt;

&lt;br /&gt;
Heat stress has previously seen a decrease in fertility in dairy cows, whilst similarly, pregnancy rates in women are recorded to be lowest during the summer season, paving way for the postulation that fertilization may be disrupted due to elevated temperatures. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
3 different experiments were performed to determine the underlying mechanism causing the disruption to fertilization due to increase in temperature. Oocytes and Spermatozoa were exposed to physiological temperatures that mirrored those of mammalian organisms. Oocytes were fertilized at 38.5-41ºC with either no-pre-incubated sperm or 38.5 / 41ºC incubated sperm, to investigate the effected on sperm plasma membrane, viability, and penetration, polyspermy, subsequent development of zygote, and embryonic competence. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
The results showed that at elevated temperatures, percentage of motile sperm were reduced, along with altered transcription due to oxidative stress, resulting in an increase in polyspermy. In addition, the zona pellucida of zygotes was sensitive to pronase digestion during heat stress, and exhibited decreased transcription of gene UCHL1, which played the role of preventing polyspermy. Rates of cell cleave and blastocysts formation were also seen to have reduced. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
Because of the results shown, this study reports that the increase in polyspermy is the most likely cause of the reduced blastocyst formation due to the reduced capability of zygotes at elevated temperatures to develop to the next stage. (Sakatani et all, 2014)&lt;br /&gt;

&lt;br /&gt;
Cyclophosphamide is an alkylating agent most commonly used to treat cancers with other chemotherapy agents. It’s used to quickly control cancerous diseases but is highly toxic. Sperm banking in those prior to cancer treatment have seen to have more effective Intracytoplasmic Sperm Injection in In Vitro Fertilization compared to those performing IVF/ICSI after their first dose of chemotherapy. This study tests whether there is correlation between the agent, Cyclophosphamide, and the reduced preimplantation embryo development, birth rate, and genetic integrity of embryos after embryo transfer. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Untreated sperm of adult male B6D2 mice were first collected. They were then administered cyclophosphamide after seven days, and were sacrificed to obtain the treated sperm. Oocytes were collected after controlled ovarian stimulation. Half the oocytes from each female were exposed with Cyclophosphamide exposed sperm and untreated sperm from the same male mice. Embryos were monitored in vitro for 2 days and were then collected for exome sequencing. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Results showed that the average percentage of oocyte survival was 94.8%, whereas for embryos treated with Cyclophosphamide, percentage of survival was significantly lowered to 49%. Birth rates after embryo transfer showed no difference between the two groups but Cyclophosphamide-treated group had lower litter size (0.8 vs 3.8) and pups per embryo transferred (2.7% vs. 14%). (Johnson et all, 2015)&lt;br /&gt;
This study argues that Cyclophosphamide exposed sperm decreased development in embryo, resulting in lowered numbers of offspring and lower number of offspring survival. Further investigation is needed in order to know the reason and mechanism behind Cyclophosphamide’s influence on male sperm and fertilization. (Johnson et all, 2015)&lt;br /&gt;

MR imaging has extended its use to evaluating and diagnosing disorders related to female infertility, including ovulatory, fallopian tube, and uterine disorders, and also pelvic enometiosis. It is used in a variety of clinical settings by providing a clear vizualization of the pelvic region and is now useful in conjunction with other diagnostic techniques like laparoscopy, hysteroscopy, and hysterosalpinogography.&lt;br /&gt;

In a group of 77 women evaluated, Laparoscopy confirmed 84% evidence of tubal disease and hysteroscopy confirmed 69% radiographic evidence of intrauterine abnormalities. IN contrast HS gave a false-positive rate of 16% and 31% respectively. Data suggests that laparoscopy is best detecting previously unsuspected tubal disease, and hysteroscopy with information of managing abnormalities. But for optimum evaluation, a combined approach of all three procedures is best.&lt;br /&gt;

&lt;div&gt;=FEMALE INFERTILITY: ''Definition''=&lt;br /&gt;
&lt;br /&gt;
&amp;quot;Infertility is defined as inability of couple to conceive after one year of unprotected intercourse.Various factors and conditions can contribute to female infertility, some of which are still unknown.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
'''''Adapted from''''' &amp;lt;pubmed&amp;gt;26150870&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
==Causes==&lt;br /&gt;
===The Genetics of Infertility: Current Status of the Field===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3885174&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article attempted to determine the role that genetics plays in female infertility. It was noted that several prominent causes of female infertility such as Galactosemia and Primary Ovarian Failure (POF) were associated with specific genes, with the GALT gene contributing to the former condition and the FMR1 gene contributing to the latter.&lt;br /&gt;
&lt;br /&gt;
===Causes of Sterility in Bosnia-Herzegovina Population===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC4499307&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
The study conducted as laid out in this article examined the causes of female sterility in the Bosnia-Herzegovina population. Married participants were arranged into various groups based upon their age. The experiment came to the conclusion that in approximately 42% of infertile married couples, female sterility was the primary cause. The two primary causes of female infertility were tubal deficiencies (31% of cases) and Diminished Ovarian Reserves (38% of cases)&lt;br /&gt;
&lt;br /&gt;
===Epidemiology, diagnosis, and management of polycystic ovary syndrome===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;PMC3872139&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This research article examines the causes of polycystic ovary syndrome (POS), a common cause of infertility in women. The article concluded that 50-70% of women suffer from insulin resistance secondary to Type 2 Diabetes and in many cases obseity, which may contribute partially to POS. Furthermore, 85-90% of women with oligomenorrhea also had POS, suggesting that it is an underlying cause. However, the exact pathophysiology of POS was not determined.&lt;br /&gt;

===Impact of physical activity on ovarian reserve markers in normal, overweight and obese reproductive age women===&lt;br /&gt;
&amp;lt;pubmed&amp;gt;25509968&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study focuses on the effect of physical activity on fertility in three groups of women at reproductive age; normal, overweight and obese. The results from the study suggest that there was a marked improvement in fertility as shown by the ovarian reserve markers for all 3 groups, however it was most significant in the overweight and obese groups. This study is relevant to our project as it gives an insight into the preventative measures that can be taken for infertility. &lt;br /&gt;
&lt;br /&gt;
===Risk factors of polycystic ovarian syndrome among Li People ===&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;26276294&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This study examined the risk factors entailed in Polycystic Ovarian Syndrdome (PCOS) amoung Li people. Using the method of a case control study, questionnaires were given to female Li people with and without PCOS. Analysis of the questionnaires showed that family history of diabetes, family history of infertility, bad mood, lack of physical exercise are all high risk factors of PCOS. As a result, management of these risk factors can be taken into consideration when preventing infertility through PCOS.&lt;br /&gt;
&lt;br /&gt;
===Vitamin D and female fertility===&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;24717915&amp;lt;/pubmed&amp;gt;&lt;br /&gt;
This article is a review focusing on research regarding Vitamin D and fertility over the past year. The review found that the levels of Vitamin D is crucial for women undergoing in-vitro fertilisation. It  was also found that Vitamin D was beneficial for women with PCOS and carried a protective effect against endometriosis. These observations suggest that having sufficient Vitamin D in your body can be preventative for problems associated with fertility.&lt;br /&gt;
&lt;br /&gt;
==Treatment==&lt;br /&gt;
&lt;br /&gt;
'''''The Effect of a Complex Multi-modality Ayurvedic Treatment in a Case of Unknown Female Infertility'''''&lt;br /&gt;
&lt;br /&gt;
This article documented a 38 year old woman's journey to giving birth, after she was advised that she was infertile (of unknown cause). The researchers detail the various modern day medical treatments she underwent to become pregnant, all of which were unsuccessful. She then decided to try holistic medicine in the form of Ayurvedic treatment, which consisted of meditation, a controlled diet and yoga. To the researchers' surprise, she became pregnant soon after, and gave birth to a healthy baby boy in 2012. The study comes to the conclusion that Ayurvedic medicine and successful birth rates do not show a strong correlation, and thus should not be favoured over standard medical treatments. However, they did state that holistic medicine could improve the overall wellbeing of the mother (in terms of stress and diet), which in turn increases the chances of becoming pregnant.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

'''''Pregnancy Rate after Controlled Ovarian Hyperstimulation and Intrauterine Insemination for the Treatment of Endometriosis following Surgery'''''&lt;br /&gt;
&lt;br /&gt;
This study investigated various treatments available for women with endometriosis, and the rate of successful pregnancies and births in patients following their treatment. The researchers came to the conclusion that a woman's chances of becoming pregnant increased following laparoscopic surgery, particularly in the first six months following the procedure. If pregnancy does not occur, controlled ovarian hyperstimulation and intrauterine insemination (COH-IU) should be the next option, due to its success rates. &lt;br /&gt;
  &lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;26247014&amp;lt;/pubmed&amp;gt;&lt;br /&gt;

&lt;br /&gt;
'''''Time-limited Hydrotubation Combined with Clomiphene Citrate Treatment for Unexplained Infertility'''''&lt;br /&gt;
&lt;br /&gt;
In this experiment, 80 random patients with &amp;quot;unexplained inferility&amp;quot; were selected and treated with hydotrubation and clomiphene citrate (CC). Of the 80 patients, 15 became pregnant, with the researchers concluding that combined hydrotubation and CC treatment increased a woman's chance of becoming pregnant to a greater degree than just CC alone. Further tests need to be completed to strengthen the correlation between the treatment and outcome.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pubmed&amp;gt;26152000&amp;lt;/pubmed&amp;gt;&lt;br /&gt;

&lt;br /&gt;
'''''Frequency and Outcome of Treatment in Polycystic Ovaries Related Infertility'''''&lt;br /&gt;
&lt;br /&gt;
This study examined treatments available to women with Polycystic Ovarian Syndrome (PCOS). It came to the conclusion that in overweight women with PCOS, weight loss, exercise and better lifestyle choices are the best treatments as they significantly increases pregnancy rates. Furthermore, clomiphene citrate (CC) and metformine combined treatments are highly effective in PCOS women, and should be one of the first options offered to a patient. &lt;br /&gt;

'''''Frequency and Outcome of Treatment in Polycystic Ovaries Related Infertility'''''&lt;br /&gt;
&lt;br /&gt;
This study examined treatments available to women with Polycystic Ovarian Syndrome (PCOS). It came to the conclusion that in overweight women with PCOS, weight loss, exercise and better lifestyle choices are the best treatments as they significantly increases pregnancy rates. Furthermore, clomiphene citrate (CC) and metformine combined treatments are highly effective in PCOS women, and should be one of the first options offered to a patient. &lt;br /&gt;

Heat stress has previously seen a decrease in fertility in dairy cows, whilst similarly, pregnancy rates in women are recorded to be lowest during the summer season, paving way for the postulation that fertilization may be disrupted due to elevated temperatures. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
3 different experiments were performed to determine the underlying mechanism causing the disruption to fertilization due to increase in temperature. Oocytes and Spermatozoa were exposed to physiological temperatures that mirrored those of mammalian organisms. Oocytes were fertilized at 38.5-41ºC with either no-pre-incubated sperm or 38.5 / 41ºC incubated sperm, to investigate the effected on sperm plasma membrane, viability, and penetration, polyspermy, subsequent development of zygote, and embryonic competence. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
The results showed that at elevated temperatures, percentage of motile sperm were reduced, along with altered transcription due to oxidative stress, resulting in an increase in polyspermy. In addition, the zona pellucida of zygotes was sensitive to pronase digestion during heat stress, and exhibited decreased transcription of gene UCHL1, which played the role of preventing polyspermy. Rates of cell cleave and blastocysts formation were also seen to have reduced. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
Because of the results shown, this study reports that the increase in polyspermy is the most likely cause of the reduced blastocyst formation due to the reduced capability of zygotes at elevated temperatures to develop to the next stage. (Sakatani et all, 2014)&lt;br /&gt;

&lt;br /&gt;
Cyclophosphamide is an alkylating agent most commonly used to treat cancers with other chemotherapy agents. It’s used to quickly control cancerous diseases but is highly toxic. Sperm banking in those prior to cancer treatment have seen to have more effective Intracytoplasmic Sperm Injection in In Vitro Fertilization compared to those performing IVF/ICSI after their first dose of chemotherapy. This study tests whether there is correlation between the agent, Cyclophosphamide, and the reduced preimplantation embryo development, birth rate, and genetic integrity of embryos after embryo transfer. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Untreated sperm of adult male B6D2 mice were first collected. They were then administered cyclophosphamide after seven days, and were sacrificed to obtain the treated sperm. Oocytes were collected after controlled ovarian stimulation. Half the oocytes from each female were exposed with Cyclophosphamide exposed sperm and untreated sperm from the same male mice. Embryos were monitored in vitro for 2 days and were then collected for exome sequencing. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Results showed that the average percentage of oocyte survival was 94.8%, whereas for embryos treated with Cyclophosphamide, percentage of survival was significantly lowered to 49%. Birth rates after embryo transfer showed no difference between the two groups but Cyclophosphamide-treated group had lower litter size (0.8 vs 3.8) and pups per embryo transferred (2.7% vs. 14%). (Johnson et all, 2015)&lt;br /&gt;
This study argues that Cyclophosphamide exposed sperm decreased development in embryo, resulting in lowered numbers of offspring and lower number of offspring survival. Further investigation is needed in order to know the reason and mechanism behind Cyclophosphamide’s influence on male sperm and fertilization. (Johnson et all, 2015)&lt;br /&gt;

&lt;br /&gt;
MR imaging has extended its use to evaluating and diagnosing disorders related to female infertility, including ovulatory, fallopian tube, and uterine disorders, and also pelvic enometiosis. It is used in a variety of clinical settings by providing a clear vizualization of the pelvic region and is now useful in conjunction with other diagnostic techniques like laparoscopy, hysteroscopy, and hysterosalpinogography.&lt;br /&gt;

In a group of 77 women evaluated, Laparoscopy confirmed 84% evidence of tubal disease and hysteroscopy confirmed 69% radiographic evidence of intrauterine abnormalities. IN contrast HS gave a false-positive rate of 16% and 31% respectively. Data suggests that laparoscopy is best detecting previously unsuspected tubal disease, and hysteroscopy with information of managing abnormalities. But for optimum evaluation, a combined approach of all three procedures is best.&lt;br /&gt;

Earlier assessment is best in women who have history of oligomenorrhea/amenorrhea, with key objective of assessment and diagnosis to rule out azoospermia, anovulation, or tubal obstruction.&lt;br /&gt;
In order to do so an assesment of ovulatory function, uterine cavity, and tubal patency by HSG/laparoscopyis needed.&lt;br /&gt;
Assessments like post coital tests, endometrial biopsies, and basal bdy temperature records are no longer a routine investigation.&lt;br /&gt;

Cyclophosphamide is an alkylating agent most commonly used to treat cancers with other chemotherapy agents. It’s used to quickly control cancerous diseases but is highly toxic. Sperm banking in those prior to cancer treatment have seen to have more effective Intracytoplasmic Sperm Injection in In Vitro Fertilization compared to those performing IVF/ICSI after their first dose of chemotherapy. This study tests whether there is correlation between the agent, Cyclophosphamide, and the reduced preimplantation embryo development, birth rate, and genetic integrity of embryos after embryo transfer. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Untreated sperm of adult male B6D2 mice were first collected. They were then administered cyclophosphamide after seven days, and were sacrificed to obtain the treated sperm. Oocytes were collected after controlled ovarian stimulation. Half the oocytes from each female were exposed with Cyclophosphamide exposed sperm and untreated sperm from the same male mice. Embryos were monitored in vitro for 2 days and were then collected for exome sequencing. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Results showed that the average percentage of oocyte survival was 94.8%, whereas for embryos treated with Cyclophosphamide, percentage of survival was significantly lowered to 49%. Birth rates after embryo transfer showed no difference between the two groups but Cyclophosphamide-treated group had lower litter size (0.8 vs 3.8) and pups per embryo transferred (2.7% vs. 14%). (Johnson et all, 2015)&lt;br /&gt;
This study argues that Cyclophosphamide exposed sperm decreased development in embryo, resulting in lowered numbers of offspring and lower number of offspring survival. Further investigation is needed in order to know the reason and mechanism behind Cyclophosphamide’s influence on male sperm and fertilization. (Johnson et all, 2015)&lt;br /&gt;

&lt;br /&gt;
Heat stress has previously seen a decrease in fertility in dairy cows, whilst similarly, pregnancy rates in women are recorded to be lowest during the summer season, paving way for the postulation that fertilization may be disrupted due to elevated temperatures. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
3 different experiments were performed to determine the underlying mechanism causing the disruption to fertilization due to increase in temperature. Oocytes and Spermatozoa were exposed to physiological temperatures that mirrored those of mammalian organisms. Oocytes were fertilized at 38.5-41ºC with either no-pre-incubated sperm or 38.5 / 41ºC incubated sperm, to investigate the effected on sperm plasma membrane, viability, and penetration, polyspermy, subsequent development of zygote, and embryonic competence. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
The results showed that at elevated temperatures, percentage of motile sperm were reduced, along with altered transcription due to oxidative stress, resulting in an increase in polyspermy. In addition, the zona pellucida of zygotes was sensitive to pronase digestion during heat stress, and exhibited decreased transcription of gene UCHL1, which played the role of preventing polyspermy. Rates of cell cleave and blastocysts formation were also seen to have reduced. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
Because of the results shown, this study reports that the increase in polyspermy is the most likely cause of the reduced blastocyst formation due to the reduced capability of zygotes at elevated temperatures to develop to the next stage. (Sakatani et all, 2014)&lt;br /&gt;

Heat stress has previously seen a decrease in fertility in dairy cows, whilst similarly, pregnancy rates in women are recorded to be lowest during the summer season, paving way for the postulation that fertilization may be disrupted due to elevated temperatures. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
3 different experiments were performed to determine the underlying mechanism causing the disruption to fertilization due to increase in temperature. Oocytes and Spermatozoa were exposed to physiological temperatures that mirrored those of mammalian organisms. Oocytes were fertilized at 38.5-41ºC with either no-pre-incubated sperm or 38.5 / 41ºC incubated sperm, to investigate the effected on sperm plasma membrane, viability, and penetration, polyspermy, subsequent development of zygote, and embryonic competence. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
The results showed that at elevated temperatures, percentage of motile sperm were reduced, along with altered transcription due to oxidative stress, resulting in an increase in polyspermy. In addition, the zona pellucida of zygotes was sensitive to pronase digestion during heat stress, and exhibited decreased transcription of gene UCHL1, which played the role of preventing polyspermy. Rates of cell cleave and blastocysts formation were also seen to have reduced. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
Because of the results shown, this study reports that the increase in polyspermy is the most likely cause of the reduced blastocyst formation due to the reduced capability of zygotes at elevated temperatures to develop to the next stage. (Sakatani et all, 2014)&lt;br /&gt;

Cyclophosphamide is an alkylating agent most commonly used to treat cancers with other chemotherapy agents. It’s used to quickly control cancerous diseases but is highly toxic. Sperm banking in those prior to cancer treatment have seen to have more effective Intracytoplasmic Sperm Injection in In Vitro Fertilization compared to those performing IVF/ICSI after their first dose of chemotherapy. This study tests whether there is correlation between the agent, Cyclophosphamide, and the reduced preimplantation embryo development, birth rate, and genetic integrity of embryos after embryo transfer. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Untreated sperm of adult male B6D2 mice were first collected. They were then administered cyclophosphamide after seven days, and were sacrificed to obtain the treated sperm. Oocytes were collected after controlled ovarian stimulation. Half the oocytes from each female were exposed with Cyclophosphamide exposed sperm and untreated sperm from the same male mice. Embryos were monitored in vitro for 2 days and were then collected for exome sequencing. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Results showed that the average percentage of oocyte survival was 94.8%, whereas for embryos treated with Cyclophosphamide, percentage of survival was significantly lowered to 49%. Birth rates after embryo transfer showed no difference between the two groups but Cyclophosphamide-treated group had lower litter size (0.8 vs 3.8) and pups per embryo transferred (2.7% vs. 14%). (Johnson et all, 2015)&lt;br /&gt;
This study argues that Cyclophosphamide exposed sperm decreased development in embryo, resulting in lowered numbers of offspring and lower number of offspring survival. Further investigation is needed in order to know the reason and mechanism behind Cyclophosphamide’s influence on male sperm and fertilization. (Johnson et all, 2015)&lt;br /&gt;

Rates of cell cleave and blastocysts formation were also seen to have reduced. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
Because of the results shown, this study reports that the increase in polyspermy is the most likely cause of the reduced blastocyst formation due to the reduced capability of zygotes at elevated temperatures to develop to the next stage. (Sakatani et all, 2014)&lt;br /&gt;

Cyclophosphamide is an alkylating agent most commonly used to treat cancers with other chemotherapy agents. It’s used to quickly control cancerous diseases but is highly toxic. Sperm banking in those prior to cancer treatment have seen to have more effective Intracytoplasmic Sperm Injection in In Vitro Fertilization compared to those performing IVF/ICSI after their first dose of chemotherapy. This study tests whether there is correlation between the agent, Cyclophosphamide, and the reduced preimplantation embryo development, birth rate, and genetic integrity of embryos after embryo transfer. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Untreated sperm of adult male B6D2 mice were first collected. They were then administered cyclophosphamide after seven days, and were sacrificed to obtain the treated sperm. Oocytes were collected after controlled ovarian stimulation. Half the oocytes from each female were exposed with Cyclophosphamide exposed sperm and untreated sperm from the same male mice. Embryos were monitored in vitro for 2 days and were then collected for exome sequencing. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Results showed that the average percentage of oocyte survival was 94.8%, whereas for embryos treated with Cyclophosphamide, percentage of survival was significantly lowered to 49%. Birth rates after embryo transfer showed no difference between the two groups but Cyclophosphamide-treated group had lower litter size (0.8 vs 3.8) and pups per embryo transferred (2.7% vs. 14%). (Johnson et all, 2015)&lt;br /&gt;
This study argues that Cyclophosphamide exposed sperm decreased development in embryo, resulting in lowered numbers of offspring and lower number of offspring survival. Further investigation is needed in order to know the reason and mechanism behind Cyclophosphamide’s influence on male sperm and fertilization. (Johnson et all, 2015)&lt;br /&gt;

Heat stress has previously seen a decrease in fertility in dairy cows, whilst similarly, pregnancy rates in women are recorded to be lowest during the summer season, paving way for the postulation that fertilization may be disrupted due to elevated temperatures. (Sakatani et all, 2014)&lt;br /&gt;
&lt;br /&gt;
3 different experiments were performed to determine the underlying mechanism causing the disruption to fertilization due to increase in temperature. Oocytes and Spermatozoa were exposed to physiological temperatures that mirrored those of mammalian organisms. Oocytes were fertilized at 38.5-41ºC with either no-pre-incubated sperm or 38.5 / 41ºC incubated sperm, to investigate the effected on sperm plasma membrane, viability, and penetration, polyspermy, subsequent development of zygote, and embryonic competence. (Sakatani et all, 2014)&lt;br /&gt;

The results showed that at elevated temperatures, percentage of motile sperm were reduced, along with altered transcription due to oxidative stress, resulting in an increase in polyspermy.

Cyclophosphamide is an alkylating agent most commonly used to treat cancers with other chemotherapy agents. It’s used to quickly control cancerous diseases but is highly toxic. Sperm banking in those prior to cancer treatment have seen to have more effective Intracytoplasmic Sperm Injection in In Vitro Fertilization compared to those performing IVF/ICSI after their first dose of chemotherapy. This study tests whether there is correlation between the agent, Cyclophosphamide, and the reduced preimplantation embryo development, birth rate, and genetic integrity of embryos after embryo transfer. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Untreated sperm of adult male B6D2 mice were first collected. They were then administered cyclophosphamide after seven days, and were sacrificed to obtain the treated sperm. Oocytes were collected after controlled ovarian stimulation. Half the oocytes from each female were exposed with Cyclophosphamide exposed sperm and untreated sperm from the same male mice. Embryos were monitored in vitro for 2 days and were then collected for exome sequencing. (Johnson et all, 2015)&lt;br /&gt;
&lt;br /&gt;
Results showed that the average percentage of oocyte survival was 94.8%, whereas for embryos treated with Cyclophosphamide, percentage of survival was significantly lowered to 49%. Birth rates after embryo transfer showed no difference between the two groups but Cyclophosphamide-treated group had lower litter size (0.8 vs 3.8) and pups per embryo transferred (2.7% vs. 14%). (Johnson et all, 2015)&lt;br /&gt;
This study argues that Cyclophosphamide exposed sperm decreased development in embryo, resulting in lowered numbers of offspring and lower number of offspring survival. Further investigation is needed in order to know the reason and mechanism behind Cyclophosphamide’s influence on male sperm and fertilization. (Johnson et all, 2015)&lt;br /&gt;
