Access anonymised HFEA data
Since the HFEA was set up in 1991 we have collected a vast amount of data on fertility treatments carried out by licensed UK clinics. The data is stored on what we call the HFEA Register.
In order to allow professionals in the sector and the wider research community to make good use of the data, we have launched an anonymised version of the Register.
The anonymised Register allows researchers to access a large and rich data set, but one that does not identify any patients, or children born as a result of treatment.
Why have we created the anonymised Register?
The Act of Parliament that set up the HFEA places tight restrictions on who can see the information we hold.
Unless the patient concerned has given their consent, we cannot release information that might lead to the identification of that patient, their partner or their child. However, we can publish anonymised information.
What information is in the Register?
The anonymised Register contains information, shown on a treatment cycle basis, such as:
- reasons for infertility
- the age of patients at treatment
- number of embryos transferred
This is the first edition of the anonymised register, and it will be updated with the latest figures on a quarterly basis. We also hope to add further data fields over time.
When data is reported by clinics to the HFEA, it goes through a validation processes. Every attempt is made to ensure that the data is as accurate as possible. However, between 1991 and 2006 the data received was added to the Register manually which inevitably introduced human errors. Data has been supplied electronically by clinics since 2007.
We have excluded from the anonymised Register anomalies in the data that are misleading or could be misinterpreted.
Who is the anonymised Register for?
The anonymised Register is designed for those working in the IVF sector and professional researchers, or research organisations, with an interest in the epidemiology of fertility treatment.

Accessing patient-identifying information
In 2008, legislation was passed that allowed researchers access to patient-identifying information from our Register, if there is consent from the patient.
Strict procedures are in place regarding the supply of identifying data to researchers. It is expected that the majority of research projects will only need access to anonymised data. Access to identifying information is a last resort.
