We're redesigning our website - we're keen for you to try it so we can hear your views on how it can be improved ahead of the official launch. Head on over to the HFEA BETA to see how it is shaping up.

Apply for information and re-register

Re-register as an identifiable donor

A man looking at information on the internetIf you donated before 1 April 2005 you can choose to remove your anonymity – and potentially become identifiable to any children born from your donation. This is known as ‘re-registering’.

If you re-register, your donor-conceived offspring may choose to make contact with you once they reach the age of 18. We will try to contact you first using the details held on file to let you know that a request for your contact details has been made.

Before deciding whether to re-register, you may wish to consider how this could impact on you and your family and we have developed some leaflets to help you with this.

We recommend that you talk these issues through with family and friends. If you think you need further help thinking through the issues, we can provide professional support.

This involves being referred to a specialist with expertise in supporting people involved in, or affected by, donation. If you donated at a UK licensed centre between August 1991 and March 2005, we can offer you a number of free sessions.

Alternatively, you can ask to speak to a counsellor at the clinic you donated at to talk through the implications of re-registering as an identifiable donor.

Bear in mind that you may not be contacted by any donor-conceived offspring. This could be for a number of reasons, including the possibility that they do not know they are donor-conceived.

If you donate through an HFEA-licensed clinic, you will not be legally responsible for any child born as result of your donation. For more information see:
