- Identify the origin of In Vitro Fertilization and the 2010 nobel prize winner associated with this technique.
In 1978, Louise Brown, the first IVF baby was born. In Vitro Fertilisation (IVF) aids couples who may have trouble conceiving or are considered infertile. IVF involves the extraction of both the oocyte (female egg) and spermatozoa (male sperm) with fertilisation occurring outside the human body in a glass dish. Once fertilisation has occurred the zygote is then implanted back in to the female uterus. The idea of human IVF started in the mid 20th century by Robert G. Edwards who had studied fertilisation for many years and in 2010 Edwards was awarded the nobel prize in physiology or medicine. [1]
- Identify a recent paper on fertilisation and describe its key findings.
McAvey B Zapantis, A, Jindal SK, Lieman HJ, Polotsky AJ. (2011 ) How many eggs are needed to produce an assisted reproductive technology baby: is more always better? Fertility Sterility. 96(2):332-5. [2] This paper looked at the optimum number of oocytes that could be used in IVF to give the highest chance of live birth. They found 6-9 oocytes was advantageous in comparison to 5 or less oocytes, as well as, 10 or more oocytes. Thus suggesting more is not always better. This may aid future IVF patients not having to receive multiple treatments.
- Identify 2 congenital anomalies.
Congenital Anomalies are considered to be defects and/or disorders present at birth, such as Achondroplasia & Polydactyly.
