To ask Her Majesty's Government how many of the oocytes frozen for a patient's own use in the UK since 2013 were frozen and thawed for the purpose of treatment by in vitro fertilisation; of those that were thawed, how many were successfully fertilised and appeared to develop normally; of those, how many were transferred to a uterus; and how many resulted in a live birth, a pregnancy, or a miscarriage.
