In vitro fertilization is one of now many different reproductive options know collectively as Assisted Reproductive Technologies (ART). These techniques continue to grow worldwide with development of new medical technologies. In vitro fertilization covers the aided fertilization process, in contrast with in vivo fertilization which is the normal uterine occuring fertilization process.
The earliest experiments 1945-48, involved fertilising oocytes that had been collected from women with spermatozoa in a petri dish. The first successful IVF was carried out in the UK in 1978 by Edwards RG, et al., receiver of the 2010 Nobel Prize in Medicine.
The Latin, In vitro = "in glass" meaning in essence a test tube as apposed to in vivo (in life or a living body), fertilisation (Aus spelling) and fertilisation (US spelling). Even in vivo fertilization can also now be considered "assisted" through some fertility drug treatments. Both processes have the same biological outcome, fusion of male and female gametes to form a diploid zygote.
In Australia, the first successful IVF occurred in 1980. and during 2005 1,596 IVF babies were born. In the same year in Australia and New Zealand 51,017 treatment cycles were reported, an increase of 13.7% of ART treatment cycles from 2004. In all countries using Assisted Reproductive Technologies (ART), pregnancy rates vary for the different methods of treatment and also between individual IVF or GIFT units. In Australia best clinical pregnancy rate (per 100 oocyte retrieval cycles) by most successful 25% of all clinics increased from 24.9% (1998) to 34.4% (2001) (NPSU data - ART 2002 report)

Trends in ART procedures
- In the last 5 years there has been a shift from day 2-3 embryo (cleavage stage) transfers to day 5-6 embryo (blastocyst) transfers.
- The proportion of blastocyst transfers has increased from 27.1% in 2006 to 52.1% in 2010.
- Increase in the transfer of vitrified (ultra-rapid frozen) embryos. Compared with 2009, the proportion has more than doubled from 18.3% to 38.2%.
- reduction in the rate of multiple birth deliveries, with a decrease from 12% in 2006 to 7.9% in 2010.
- shifting to single embryo transfer, the proportion of which increased from 56.9% in 2006 to almost 70% in 2009 and 2010.
- decrease in the multiple delivery rate was achieved while clinical pregnancy rates remained stable at about 23% per cycle.

Oldest IVF Mother
There is still risk, ethical and genetic debate about very old women becoming pregnant by IVF.
- 2003 India - A 65-year old Indian woman was the oldest in the world to give birth by IVF.
- 2006 United Kingdom - A 62-year old woman has become the UK's oldest woman to give birth to a child.
- 2008 Australia - A 54-year old woman was Australia's oldest woman pregnant by IVF (most Australian IVF clinics do not treat women over 50)
- 2010 Australia - A 57-year old woman is now the oldest mother to give birth in Australia, has delivered IVF twins in Western Australia.
IVF Sex Ratios
A recent paper looked at Australian assisted reproductive technology (ART) data (2002-2006) studied the effect on human sex ratio at birth by different procedures. PMID:20875033
- "More males were born following in vitro fertilisation single embryo transfer (IVF SET) (53.0%) than intracytoplasmic sperm insemination (ICSI) SET (50.0%), and following blastocyst SET (54.1%) than cleavage-stage SET (49.9%). For a specific ART regimen, IVF blastocyst SET produced more males (56.1%) and ICSI cleavage-stage SET produced fewer males (48.7%). The change in the sex ratio at birth of SET babies is associated with the ART regimen. The mechanism of these effects remains unclear. Fertility clinics and patients should be aware of the bias in the sex ratio at birth when using ART procedures."
There have been many attempts to establish morphological, biochemical or molecular markers of oocyte quality with variable results by different groups. Recently studies have also looked at the molecular quality of cumulus and granulosa cells. Earlier studies of this support cell population have looked at markers of mitosis and apoptosis, with positive and negative correlation respectively.
Following removal of these support cells, oocyte features such as; nuclear maturation status, meiotic spindle presence, cytoplasm morphology, zona pellucida structure, and polar body presence and structure have all been investigated.
Several different microscopic techniques have also been used to visually analyse oocyte appearance:
- normal light microscopy
- phase contrast microscopy
- differential interference microscopy
- polarized light microscopy
- confocal microscopy (not for clinical use)
A study has used polarization microscope to identify the spindle in rescue ICSI of unfertilized oocytes appears to result in better normal fertilization rate and less 3PN rate compared to the control group.
In Vitro Maturation
In Vitro Maturation (IVM) is a term used to describe a range of techniques for developing ovarian follicles and oocytes outside of the body. These oocytes are generally retrieved from the antral follicles of either unstimulated or minimally stimulated ovaries. The technique has been suggested for polycystic ovary syndrome and other ovarian pathologies for fertility preservation. This is a relatively new approach to human fertility.
Assisted Reproductive Technology (Australia and New Zealand)
- Over 100,000 ART babies born over the last three decades in Australia and New Zealand.
- ART children estimated as 3.3% and 2.0% of all children currently born in Australia and New Zealand respectively.
Birthweight percentiles by gestational age for births following assisted reproductive technology in Australia and New Zealand, 2002-2010
- "What is the standard of birthweight for gestational age for babies following assisted reproductive technology (ART) treatment? A total of 69 315 births (35 580 males and 33 735 females) following ART treatment were analysed for the birthweight percentile. Preterm births (birth before 37 completed weeks of gestation) and low birthweight (<2500 g) were reported for 9.7 and 7.0% of live born singletons following ART treatment. The mean birthweight was 3280 g for live born singletons following fresh cycles (3338 g for male infants and 3217 for female infants) and 3413 g for live born singletons following thaw cycles (3475 g for male infants and 3349 for female infants). The comparison of birthweight percentile charts for ART births and general population births provide evidence that the proportion of SGA births following ART treatment was comparable to the general population for SET fresh cycles and significantly lower for thaw cycles. Both fresh and thaw cycles showed better outcomes for singleton births following SET compared with DET. Policies to promote single embryo transfer should be considered in order to minimize the adverse perinatal outcomes associated with ART treatment."
|ART in Australia and New Zealand 2010
||ART in Australia and New Zealand 2009 9 Nov 2011
|2005 - 51,017 treatment cycles reported to ANZARD in Australia and New Zealand in 2005. Of these cycles, 91.1% were from Australian fertility centres and 8.9% from New Zealand's centres. There is an increase of 13.7% of ART treatment cycles from 2004.|
Average age of women was 35.5 years (35.2 years in 2002). Women aged older than 40 years has increased from 14.3% in 2002 to 15.3% in 2005.
Since ANZARD was established in 2002 there has been a significant increase in the number of embryos transfer cycles where women received single-embryo transfers (SET). SET cycles accounted for 48.3% of embryos transfer cycles in 2005, compared to 28.4% in 2002. The increase of SET cycles resulted more singleton deliveries. The proportion of singleton deliveries was 85.9% in 2005, the highest proportion ever reported.
Babies born to women who had a single-embryo transfer had better outcomes compared to babies born to women who had a double-embryo transfer (DET). In 2005, there were 3,681 SET babies and 5,589 DET babies. In SET babies, 96.1% were singletons, compared to 61.6% singletons in DET babies. SET babies had a lower proportion of preterm babies (11.7%), compared to 30.6% in DET babies. Similarly, 8.0% of SET liveborn babies were low birthweight, compared to 25.0% in DET liveborn babies.
Perinatal mortality rate is a measure of perinatal outcomes. In 2005, for all babies born following ART treatment, the perinatal mortality rate was 14.7 deaths per 1,000 births, a 23.8% decrease from 19.3 deaths per 1,000 births in 2004. The perinatal mortality rate was the lowest among singletons born following SET (7.3 deaths per 1,000 births) in 2005.
2004 - 41,904 IVF treatment cycles were started in Australia 92.6% (38,823) and New Zealand 7.4% (3,081). (More? NPSU Assisted Reproduction Technology Reports)
In Vitro Fertilization - ABC News Baby born from frozen embryo
"In what's thought to be a world first, a baby has been born in Melbourne using a woman's frozen egg and a donor's frozen sperm which created an embryo that was also frozen, then thawed and implanted into the mother"
"JOHN MCBAIN: Oh egg freezing is very difficult. Embryo freezing itself is very well established. We would probably have about 55 per cent of all the babies born from our program, and that's about 1,400 a year, come from frozen embryos. So, that's very well established technology. But even with these embryos, only 70 per cent of the embryos survive the freezing and thawing. With eggs, it's closer to 40 to 50 per cent, and then you have to have the number which don't fertilise following that, and then you have to have those which end up being frozen, possibly not surviving the embryo freezing stage too, and that's a reason we don't promote it."
Regulation of Assisted Reproductive Technology
Assisted Reproductive Technology (ART) , including IVF (or in vitro fertilisation) is regulated in Australia through both legislative and voluntary compliance frameworks. Legislation in three states is underpinned by a national system of accreditation by the Reproductive Technology Accreditation Committee (RTAC) of the Fertility Society of Australia, which is in turn is underpinned by guidelines produced by the NHMRC. This is outlined in more detail below.
- ART is regulated by specific legislation in three States, the Victorian Infertility Treatment Act (1995) , the South Australian Reproductive Technology Act (1988) and the Western Australian Human Reproductive Technology Act (1991) . Each of these pieces of legislation establishes a State regulatory body which issues Licences to clinics that provide ART services.
- There is no Commonwealth legislation covering the regulation of ART clinical practice.
- The Research Involving Human Embryos Act 2002 includes a requirement that use of non-excess ART embryos occurs in an RTAC-accredited ART clinic.
Reproductive Technology Accreditation Committee (RTAC). RTAC, under the Fertility Society of Australia, administers a national Code of Practice and a system for the accreditation of ART clinics in Australia. Through its Code of Practice, RTAC sets professional and laboratory standards for ART clinical practice.

Births Resulting From Assisted Reproductive Technology: Comparing Birth Certificate and National ART Surveillance System Data, 2011
- This report compares data on births resulting from assisted reproductive technology (ART) procedures from 2011 birth certificates with data from the 2011 National ART Surveillance System (NASS)
- Birth certificate data are based on 100% of births registered in 27 states and the District of Columbia. NASS data included all ART cycles initiated in 2010 or 2011 for which a live birth in 2011 was reported.
- Overall, the percentage of births resulting from ART procedures was 2.06 times higher for NASS data (1.44%) compared with birth certificate data (0.70%). The ratio for each jurisdiction varied from 1.04 for Utah and Wisconsin to 7.50 for Florida. Higher-risk groups had more consistent reporting between data sources [e.g., triplet or higher-order multiples (1.36) compared with singletons (2.11)].
- Births resulting from ART procedures appear to be underreported on the birth certificate; however, the magnitude of underreporting varied by jurisdiction and maternal-infant health characteristics.
- Number of ART clinics in the United States - 474
- Number of ART clinics that submitted data - 443
- Number of ART cycles reported - 147,260 (Excludes banking cycles and cycles in which a new treatment procedure was being evaluated)
- Number of live-birth deliveries resulting from ART cycles started - 47,090
- Number of infants born as a result of ART cycles performed - 61,564

Human Fertilisation and Embryology Authority UK (HFEA)
The UK Human Fertilisation and Embryology Authority (HFEA) was established in August 1991 following the passing of the Human Fertilisation and Embryology Act 1990 (HFE Act).
The HFEA's principal tasks are to:
- License and monitor clinics that carry out in vitro fertilisation (IVF) and donor insemination
- License and monitor research centres undertaking human embryo research
- Regulate the storage of gametes and embryos
Society of Obstetricians and Gynaecologists of Canada summary statements (for January 2005 to December 2012) lists 15 key statements for pregnancy outcomes after assisted human reproduction
Sweden had its first child born after in vitro fertilisation 20 years ago. A recent paper in BMJ looks at the change in multiple birthrates since a change in the early 1990s, to reduce the number of embryos transferred in the clinic from three to two.
"The rate of multiple births after in vitro fertilisation increased to a maximum of 29% in 1991 but fell to 18.5% by 2001, resulting in a 70% reduction of preterm births"
Controlled Ovarian Stimulation
A variety of drug based techniques are used to stimulate maternal oocyte development, called controlled ovarian stimulation (COS), for any in vitro fertilization procedure. The recommended for technique will vary for some procedures and also from clinic to clinic and between countries.
An example of ovarian stimulation (based on)
- Gonadotrophin releasing hormone agonist (GnRHa) triptorelin acetate (0.1 mg/day) treatment started on the 22nd day of the preceding menstrual cycle.
- Human menopausal gonadotrophin (HMG) and/or follicular stimulating hormone (FSH) was carried out daily 12 to 15 days later.
- Dosage may vary dependent upon patient response and can be monitored by hourmone levels (oestradiol) and transvaginal ultrasound (follicular size).
- The resulting ovulatory wave generates large follicles (greater than 18 mm in diameter).
- Human chorionic gonadotrophin (HCG) is then administered (36 to 38 h later)
- Clinical transvaginal puncture is used to collect from these follicles cumulus-oocyte complexes.
- Oocytes are then isolated from these cumulus-oocyte complexes.
Both men and women undergoing clinical procedures of chemotherapy and/or radiotherapy (ionizing radiation) can have induced gametogenic failure.
Women undergoing clinical procedures of chemotherapy and/or radiotherapy (ionizing radiation) can have induced premature ovarian failure. Therefore a growing reproductive option has been the collecting of oocytes or ovarian tissue before commencing these procedures and storing ("banking") by cryopreservation for later use. One major issue is coordination of the two procedures, as most cancer therapies commence immediately, and most reproductive procedures require substantial preparation time. Currently the cryopreservation techniques required for ovarian tissue preservation are also improving all the time. In a number of clinics women with breast cancer and of reproductive age are being counselled about their reproductive options.
Chemotherapy, alkylating and alkylating-like agents attach to the guanine base of DNA, cross-linking the DNA, preventing replication and cell division. Some examples include: busulfan, carboplatin, chlorambucil, cisplatin, cyclophosphamide, dacarbazine, ifosfamide, thiotepa
A third potential option that may also in future be available is the transplanting (allografting) of ovarian cortex between individuals, this has recently been carried out between genetically non-identical sisters.
A recent paper described the current practice of spermatozoa banking in the United Kingdom in relation to cancer patients. The UK Human Fertilization and Embryology Authority have now extended the period of storage permitted by their regulations to 55 years. They point to a lack of "national and international guidelines for the provision, organization, maintenance and management of the cryopreservation services."
Ovarian reserve is a term referring to the evaluation of ovary oocyte (egg) number and quality. A negative finding has been described as Diminished Ovarian Reserve, or an ovarian insufficiency or premature ovarian failure and may be seen in adult childhood cancer survivors and adult patients undergoing a number of therapies.
The anti-Müllerian hormone (AMH) level is currently the most sensitive marker of ovarian reserve.

For a full list of terms see ART Glossary
- empty follicle syndrome - (EFS) Term used to describe a condition in which no oocytes are recovered/obtained after an apparently successful ovarian stimulation.
- follicle stimulating hormone - (FSH, gonadotropin) A glycoprotein hormone secreted by anterior pituitary (adenohypophysis gonadotrophs, a subgroup of basophilic cells) and acts on gametogenesis and other systems in both males and females. In females, FSH acts on the ovary to stimulate follicle development. Negative feedback by inhibin from the developing follicle decreases FSH secretion. In males, acts on the testis Sertoli cells to increase androgen-binding protein (ABP) that binds androgens and has a role in spermatogenesis. FSH-defficiency in females results in infertile (block in folliculogenesis prior to antral follicle formation) and in males does not affect fertility (have small testes but are fertile). FSH protein has a molecular weight 30 kDa and a 3-4 hour half-life in circulation. Gonadotrophins have been used clinically in humans for the treatment of infertility.
- human chorionic gonadotropin - (hCG, human chorionic gonadotrophin) Placental hormone initially secreted by cells (syncitiotrophoblasts) from the implanting conceptus during week two, supporting the ovarian corpus luteum, which in turn supports the endometrial lining and therefore maintains pregnancy. Hormone can be detected in maternal blood and urine and is the basis of many pregnancy tests. Hormone also stimulates the onset of fetal gonadal steroidogenesis, high levels are teratogenic to fetal gonadal tissues.
- human menopausal gonadotropin - (HMG) A clinical hormone preparation used in assisted reproductive technologies (ART). This hormone is collected from the urine of menopausal women and has similar biological activity to that of follicle stimulating hormone (FSH). This is used in an injectable form along with human chorionic gonadotropin (hCG) to induce ovulation. Some commercial product names include Menogon or Organon.
- triptorelin acetate - A gonadotropin-releasing hormone (GnRH) agonist used clinically in an acetate or pamoate form inreproduction for assisted reproductive technologies (ART, in vitro fertilization, IVF). This decapeptide (pGlu-His-Trp-Ser-Tyr-D-Trp-Leu-Arg-Pro-Gly-NH2) agonist stimulates the pituitary to decrease secretion of gonadotropins luteinizing hormone (LH) and follicle stimulating hormone (FSH). Also used for other clinical conditions.
- zona pellucida birefringence - (ZPB) Optical property of the zona pellucida using polarization imaging when viewed microscopically. Used to qualitatively predict the developmental potential of a in vitro matured metaphase-II (MII) oocytes. High birefringence has been associated with oocytes contributing to conception cycles when compared with those of nonconception cycles and higher implantation, pregnancy, and live birth rates from transferred oocytes.
