We hold information on all fertility treatments involving a donor since 1 August 1991. Learn more about what you can find out about your or your child’s donor and genetic siblings.
Since 1991, we've held a database of information about every fertility treatment carried out in the UK, called the Register.
Donor-conceived people and their parents can apply to us for information held about their donor and genetic siblings on the Register.
For enquiries, contact openingtheregister@hfea.gov.uk.

You may have seen that DNA testing kit company 23andMe filed for bankruptcy protection in the United States in March 2025. The HFEA does not regulate home DNA testing and matching services.
In May 2025, the UK Information Commissioner’s Office called for 23andMe customers’ sensitive personal data to be protected.
You can read 23andMe’s FAQs on their website.
Home DNA testing and matching websites have implications for donor-conceived people. Using one of the home DNA tests these sites offer plus opting in (or not ‘opting out’) of their ‘matching services’, could mean that your donor, or donor-conceived genetic siblings become identifiable to you and vice versa. It’s also possible that a donor-conceived person might be identified by inference, if they have a close genetic relative using home DNA testing and matching services. Even if the donor-conceived person has not used such a service themselves, the information from the matching service may be able to be combined with other publicly available information about the relevant person, and their donor conceived status and/or their identity could be possible to infer.
It’s natural to have questions about your origins. Depending on when you were treated you may be able to apply to us for information about your donor.
Finding out about your donor and genetic siblingsThe Donor Conceived Register helps to connect donor-conceived people who were conceived before 1 August 1991 with their donor and siblings. The administration of the DNA testing along with the counselling service is provided by the Liverpool Women's NHS Foundation Trust.
Finding out about your donor and genetic siblingsIf you're donor-conceived, you could have one or more donor-conceived genetic siblings in up to nine other families, or you could have none.
Finding out about your donor and genetic siblingsIf you’re over 18, you can join our Donor Sibling Link and potentially get in touch with your donor-related siblings.
