 In response, Leighton has argues that there are important disanalogies between adoption and gamete donation such that there may be no inconsistency in prohibiting anonymity in one case but not the other (Leighton 2014). For instance, adoptees are generally relinquished by their initial parent(s), and are often not raised by either of their genetic parents. In the case of gamete donation there is no similar relinquishing of parenthood, and often one of the genetic parents is also a social parent. These differences may very well result in divergences in the experiences of adoptees and donor-conceived individuals. For instance, adoptees might feel abandoned by their initial parents, and be curious about why they were relinquished, something that is unlikely to be the case in gamete donation. Furthermore, Leighton argues that since adoption has a history of stigmatization in the West while gamete donation has no such history, there is good reason to think that the psychological impact of anonymous adoption on adoptees will be different from the psychological impact of anonymous gamete donation on donor-conceived individuals (Leighton 2014).
