This episode of the Progress Educational Trust (PET) podcast discusses an imminent change that will have consequences for people involved in – and affected by – donor conception. The discussion is chaired by Sarah Norcross (Director of PET), with contributions from: ⚫ Rachel Cutting (Director of Compliance and Information at the Human Fertilisation and Embryology Authority) ⚫ Laura Bridgens (donor-conceived person, and Director of Donor Conceived UK) ⚫ Rebekah Dundas (mother of three donor-conceived children) ⚫ Nina Barnsley (Director of the Donor Conception Network) In October 2023, some people who were conceived from donor gametes in the UK – where the relevant sperm or eggs were donated after the UK abolition of donor anonymity came into force – will reach the age of 18. From this point forward, a growing number of donor-conceived people will be officially entitled to ask the UK's fertility regulator – the Human Fertilisation and Embryology Authority (HFEA) – for their donor's full name, date of birth, and last known address. The HFEA has launched a campaign to raise awareness of the changing situation, and to encourage relevant donors to ensure that they are contactable. This entails the donor providing up-to-date contact details to the clinic where they donated 18 or more years ago (if that clinic still exists), and/or providing these details to the HFEA. In this discussion a donor-conceived person, a parent of donor-conceived children, and representatives of the HFEA and the Donor Conception Network discuss practical, personal and ethical aspects of disclosing donor information. PET is grateful to the Scottish Government for supporting this discussion. PET is also grateful to Jon Nicoll, who created the opening and closing music for its podcast.
