LAB 1 ASSESSMENT

1. Identify the origin of In Vitro Fertilization and the 2010 nobel prize winner associated with this technique.

In vitro fertilization (IVF) is a fertility technique with a history that can be traced back to as early as the 1890's when the transfer of rabbit embryos from one mother to another was achieved successfully by Walter Heape (Metro IVF, 2011). The first ever attempt to fertilize a human egg in vitro was in 1973, although this attempt was unsuccessful as the embryo failed to implant itself into the wall of the uterus. The first successful attempt at IVF was with the birth of Louise Brown on 25th July, 1978, in Oldham, Greater Manchester, UK. Brown became known as the world's first successful IVF baby conceived outside the human body (Monash IVF, 2011). Credit for this achievement was given to embryologist Dr. Robert G. Edwards and gynecologist Dr. Patrick C. Steptoe.

Dr. Robert G. Edwards was awarded the 2010 Nobel Prize in Medicine or Physiology for his development of IVF.

2. Identify a recent paper on fertilisation and describe its key findings.

Reference: Singh N, Gupta P, Mittal S, Malhotra N. Correlation of body mass index with outcome of in vitro fertilization in a developing country. Arch Gynecol Obstet. 2011 Jul 27. [Epub ahead of print] PubMed PMID: 21792549.

This article’s main objective is to examine the effect of a woman’s body mass index (BMI) on ovarian response to stimulation and the outcome of IVF. The findings showed that oocyte quality decreased with increasing BMI, resulting in reduced clinical pregnancy rate and thus impairment of IVF outcome. It was also shown that an increase in BMI does not affect ovarian response to stimulation.

3. Identify 2 congenital anomalies.

Trisomy 21 (Down Syndrome)

Polydactyly
