The information is not available in the format requested. The Human Fertilisation and Embryology Authority (HFEA) holds information on the number of pregnancies, interpreted as instances where one of more foetal heart pulsation was recorded, and records of total numbers of miscarriages, not by weeks, from 2014 to 2023 which is shown in the following table:
Pregnancies | 609 |
Miscarriages | 93 |
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.
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:
Embryos transferred | 2,949 |

The information is not held in the format requested. The Human Fertilisation and Embryology Authority (HFEA) has advised that it does not hold information on the method of freezing for the whole period requested, the reasons the eggs were frozen, or how many eggs did not thaw satisfactorily or were considered unsuitable and how many of the eggs thawed underwent attempts at fertilisation. The following table shows the number eggs fertilised, the number of embryos created, and the number of embryos transferred from 2014 to 2023:
Eggs fertilised | 29,029 |
Embryos created | 18,498 |
Embryos transferred | 2,949 |
Data is as recorded by the HFEA on 17 December 2025 and reflects the data on this date and therefore may change over time.

The Human Fertilisation and Embryology Authority (HFEA), as the United Kingdom wide regulator of fertility treatment, has no statutory role in the medical follow up for children conceived through in vitro fertilisation, including instances where thawed eggs are used in treatment.
The HFEA’s expert Scientific and Clinical Advances Advisory Committee monitors new studies relating to assisted reproductive technologies, including any impact on children born from treatments.
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.
