Lab 1 Online Assessment
1. Identify the origin of In Vitro Fertilization and the 2010 nobel prize winner associated with this technique.
An American doctor, John Rock was the first to extract an intact fertilised egg, which is an important technique used to complete IVF today. Robert Edwards was awarded the 2010 nobel prize for his success in replicating conception through IVF.
2. Identify a recent paper on fertilisation and describe its key findings.
Pregnancy after Age 50: Defining Risks for Mother and Child. Kort DH, Gosselin J, Choi JM, Thornton MH, Cleary-Goldman J, Sauer MV. Am J Perinatol. 2011 Aug 1.
In 2011, a study was performed on women over the age of 50 undergoing IVF treatment and its associated risks. The study shows that with increased maternal age, the risks associated with birth defects and maternal complications is greatly increased.
3. Identify 2 congenital anomalies.
Cleft Palate and congenital hip dysplasia
