Question to the Department of Health and Social Care:

To ask His Majesty's Government how many women in the UK had their oocytes frozen for social purposes in (1) 2015, (2) 2016, (3) 2017, (4) 2018, (5) 2019, (6) 2020, (7) 2021, (8) 2022, (9) 2023, (10) 2024, and (11) 2025.

The Human Fertilisation and Embryology Authority (HFEA) does not hold information on the reasons eggs were frozen. Data from 2015 to 2023 is available on the number of patients undergoing egg freezing cycles per year, without the reasons the eggs were frozen, and are as follows: 1,020 in 2015; 1,165 in 2016; 1,365 in 2017; 1,755 in 2018; 2,130 in 2019; 2,030 in 2020; 3,400 in 2021; 3,910 in 2022; and 5,515 in 2023. This information is from the HFEA Register.
