Hello, I'm a student currently enrolled in the embryology course at UNSW. =3

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

In Vitro Fertilisation (IVF) was being explored in the 1950's by a scientist named Robert G. Edwards, who decided to investigate the possibility of fertilisation occurring outside of the body. Robert G. Edwards developed the theoretical technique and the media which would allow fertilisation to occur, and with the oocytes obtained by gynaecologist Patrick Steptoe, managed to develop the technique of IVF. Success was granted in 1969, when he first observed successful fertilisation within the test tube. Further success followed in 1977, with the birth of a healthy baby, Louise Brown, through the use of IVF.

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

The article: "Obstetric outcome after in vitro fertilization with single or double embryo transfer, written by Sazonova A. et al, published in the journal of human reproduction in December 1, 2010. Generally, children that are born using the technique of in vitro fertilization (IVF) have a poorer outcome when compared to children born without assisted treatment. However, with a new technique, known as single embryo transfer (SET) in which a single blastocyst is implanted into the uterine wall, this poor outcome may be resolved. This paper observed the study of several subtypes of SET and double embryo transfer (DET) used amongst the general Swedish population.

3. Identify 2 congenital anomalies.
