NEW – SBA Questions on Elective Egg Freezing

Approximately what percentage of IVF cycles in the UK are egg-storage cycles?

A 29-year-old woman wants to freeze her eggs electively but is anxious because a friend was told some years ago that eggs could be stored for only 10 years and might then have to be discarded. She asks whether it is worth freezing at her age. Under current UK law, which is the most accurate advice?

A 32-year-old woman has 10 eggs vitrified in a single cycle. Which is the most appropriate estimate of cumulative live birth rate to discuss with her?

A 34-year-old woman attends a fertility clinic with her partner of two years to discuss fertility preservation for non-medical reasons. She is not yet ready to have a child. Her partner suggests that they should create and freeze embryos using his sperm, as he understands embryo freezing to be more established than egg freezing. She asks the clinician whether there is any legal difference in the UK between storing her eggs and storing embryos created with her partner. Which statement most accurately describes the position under the Human Fertilisation and Embryology Act 1990 (as amended)?

A 31-year-old nulliparous woman is undergoing ovarian stimulation for elective egg freezing for non-medical reasons. Her BMI is 21 kg/m², her AMH is 42 pmol/L and her baseline antral follicle count is 32. She has a history of polycystic ovarian morphology on ultrasound. She is being stimulated with recombinant FSH in a GnRH antagonist protocol. On day 10 of stimulation, she has 22 follicles over 12 mm and a serum oestradiol of 18,000 pmol/L. Which measure would most effectively reduce her risk of ovarian hyperstimulation syndrome while allowing oocyte collection to proceed?
