Question to the Department of Health and Social Care:

To ask the Secretary of State for Health, how many women have submitted their oocytes for freezing (a) as a result of medical treatment affecting their fertility and (b) for other reasons, in each of the last five years.

The Human Fertilisation and Embryology Authority (HFEA) has advised that data is not collected in the format requested. The HFEA collects data for the total number of women who submitted their oocytes for freezing in each of the past five years, but does not collect the reasons why the oocytes are frozen.
