Question to the Department of Health and Social Care:

To ask His Majesty's Government how many embryos derived from frozen eggs were transferred to the uterus for the purpose of producing a baby between 2014-24.

Information is not available in the format requested. The Human Fertilisation and Embryology Authority (HFEA) has provided information on the total number of embryos transferred from patients’ own thawed eggs for the period 2014 to 2023, rather than a subset of eggs stored, which is shown in the following table:

The data is as shown on the HFEA’s register database on 17 December 2025. This is a live database so these figures reflect the data on this day and are likely to change over time. This reflects time needed for clinics to submit data and undergo validation as stated on the HFEA register. Data shown includes only treatments using patients own thawed eggs.
