Reply to 'Gamete donation in the UK: Time to think again'
As regards donor anonymity, both the UK's own data - as recorded by the Human Fertilisation and Embryology Authority (HFEA) - and data from overseas indicate that there is no simple cause-effect relationship between provisions regarding donor anonymity and the availability of donors. Jurisdictions that protect donor anonymity still do not have enough donors to meet demand and individual clinics have reported their ability to recruit identifiable donors (2). Of course, there will always be individuals who would not be willing to donate if they were required to disclose their identity to any offspring - a factor that needs to be taken into account in ending an existing policy protecting donor anonymity; in the same way we know from anecdotal evidence (because overall the empirical research base is not robust) that there are individuals who would be willing to donate only if any offspring were able to learn the identity of the donor. If facilitating the supply of donors is a key objective, then it is important to identify and recruit this group of potential donors. In the UK, in the lead-up to the removal of donor anonymity in 2005, most attention was focused on the potential impact of this change on sperm donor recruitment. Existing evidence up to that point suggested that oocyte donors were less concerned with concealing their anonymity than their male counterparts - and with hindsight it should be conceded that insufficient attention was paid to the possible impact of the legal change on recruitment of potential oocyte donors.
The Bridge Centre also questions the impact of the change in law on donor anonymity on the ability of donor-conceived people to find out about their biogenetic history, given that few parents disclose to their donor-conceived children the nature of their conception. Once again, the empirical evidence is limited, but what there is suggests an increasing trend in levels of parental disclosure (3). Of course it remains to be seen what impact the recent emphasis on early parental disclosure outlined in the Human Fertilisation and Embryology Act 2008 will have in the UK. In contrast to the Bridge Centre's assertion that the 'right' of access to biogenetic information should be withdrawn from donor-conceived people, the trend internationally is firmly in the opposite direction (4).
