Lab1 Assessment:

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

The first in vitro fertilization studies were related to non- mammalian aquatic species. These studies on animals with external fertilization played an important role in the comprehension of the fertilization process. Further studies engaged in mammals. In 1959 experiments with rabbits succeeded which led to the first viable mammal offspring via IVF. The in vitro fertilization therapy in humans was developed by Robert G. Edwards and the gynaecologist Patrick C. Steptoe. In 1978 the first human baby was born by means of IVF. In 2010 the English scientist Robert G. Edwards received the “Nobel Prize in Physiology or Medicine” for the development of human IVF.

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

The paper shows that the chance of becoming pregnant for infertile women undergoing a fertility treatment is not correlated with emotional stress. The meta- analysis included fourteen studies with 3583 infertile women receiving a single cycle of fertility treatment. The effect of pretreatment anxiety or depression was measured with the standardised mean difference between women with a successful conception and those without.

3. Identify 2 congenital anomalies.

- Transposition of the great vessels

- Anencephaly
