1      How to prepare.
What to read. Revision system. Study buddies. Statistics. Urogynae.

2      SBA. RCOG sample obstetric
These can be downloaded from the RCOG website: https://www.rcog.org.uk/en/careers-training/mrcog-exams/part-2-mrcog/format/part-2-mrcog-sbas-single-best-answer-questions/part-2-mrcog-obstetric-sbas/. Some of the sample questions have come in the exam, so it is worth going through them.

3      Surrogacy.
I have put this in to illustrate the point that even seemingly super-specialised TOG articles can feature in the exam. There was a TOG article: “Surrogate pregnancy: ethical and medico-legal issues in modern obstetrics” by Celia Burrell and Hannah O'Connor, that I suspect that most people barely read. TOG. Volume 15, Issue 2, April 2013; Pages 113–9. The topic turned up as part of an OSCE a year or two later. There are a number of key legal points, which we will discuss.
Abbreviations.
ART:           assisted reproductive technology
CF:              commissioning father
CM:            commissioning mother
CPs:            commissioning parents
PO:             parental order
SM:             surrogate mother

Scenario 11.
A SM decides at 10 weeks that she does not wish to be pregnant and arranges to have a TOP. The CPs. hear about this and object strongly. To whom should they apply to have the TOP blocked?
Scenario 12.
A woman has hysterectomy and BSO to deal with extensive endometriosis at the age of 30. She marries two years later and her sister offers to act as surrogate. She undergoes IVF and 4 embryos are created. One is transferred and a successful pregnancy ensues. The baby is adopted by the woman and her husband. The 3 remaining embryos were frozen. Four years later the woman falls out with her sister, but finds another surrogate and wishes to proceed with another pregnancy. The sister says she does not want her eggs to be used and that the frozen embryos should not be transferred. Does the sister have the legal right to block the use of the embryos? Yes / No.
