Question to the Department of Health and Social Care:

To ask His Majesty's Government, between 2014 and 2019, how many women undergoing a uterine transfer of one or more embryo(s) produced by fertilising a thawed egg had a positive pregnancy test; and how many pregnancies resulted in a spontaneous abortion (1) before 12 weeks of gestation, and (2) after 12 weeks of gestation.

This information is not held in the format requested. However, the following table shows the number of pregnancies and miscarriages from treatments using patients own thawed eggs from 2014 to 2019.

Source: The Human Fertilisation and Embryology Authority (HFEA)

Notes:

1. Positive pregnancy test is interpreted as instances where one or more foetal heart pulsation was recorded.
2. The data is as shown on the HFEA’s register database on 20 October 2022. This is a live database so these figures reflect the data on this day are likely to change over time. Data shown includes only treatment using patients own thawed eggs.
