Donor gametes: anonymous or identified?

The practice of gamete donation has, until recently, been shrouded in secrecy. The stigma associated with infertility and, in particular, donor insemination has been the main factor contributing to this secrecy. Over the last 20 years, this secrecy and the anonymity of the gamete donors has been challenged. In the first instance, the challenge came from governments in some countries legislating to abolish donor anonymity. Counsellors, social workers and psychologists advocating for the interests and needs of children and their families, as well as parents who did not wish to keep gamete donation secret from their children, were also instrumental in the change of policies and practice. Those offspring who know that they were conceived as a result of gamete donation are also calling for an end to the secrecy. This chapter reviews the changes that have occurred and which are still occurring, and reviews the research associated with these changes.
