Lab 1: Assessment
Identify the origin of In Vitro Fertilization and the 2010 nobel prize winner associated with this technique.
- John Rock, an American obstetrician and gynecologist, was a pioneer in in vitro fertilization and sperm freezing. He helped many of his patients achieve pregnancy and became known as a "ground-breaking infertility specialist." In 1977, Patrick Steptoe and Robert Edwards successfully carried out a pioneering conception which resulted in the birth of the world's first baby to be conceived by IVF.
- Robert G. Edwards was awarded the 2010 Nobel Prize in Physiology or Medicine.
Identify a recent paper on fertilisation and describe its key findings.
- | Correlation of body mass index with outcome of in vitro fertilization in a developing country.
- To correlate ovarian response to stimulation and IVF outcome according to the women's body mass index (BMI). The conclusion came to an increased BMI is associated with poorer IVF outcome.
Identify 2 congenital anomalies.
- Down syndrome (Trisomy 21)
- Turner's syndrome
--Mark Hill 10:03, 3 August 2011 (EST) These answers are fine.
Lab 2: Assessment
Identify the ZP protein that spermatozoa binds and how is this changed (altered) after fertilization.
- The ZP protein that binds to the spermatozoa is the ZP3. Plasma membranes of the spermatozoa and oocyte fuse, during fertilisation, and the head and tail of the spermatozoa enter the oocyte, leaving the spermatozoa's plasma membrane attached to the oocyte's plasma membrane.
