 Another reason offered for prohibiting anonymous gamete donation is that it prevents donor-conceived individuals from making health decisions informed by family medical history. If individuals are not informed about being donor-conceived, they risk making medical decisions on the incorrect assumption that their social family’s medical background reflects their own. And even if such individuals are informed that they are donor-conceived, they still suffer from an absence of medical information that is generally available to others (Ravitsky 2012). While it is true that medical information could be provided at the time of donation in a manner that preserves the anonymity of the donor, some argue that, as our understanding of congenital disease changes, new information is likely to become relevant (Leighton 2014; McGee, Brakeman, &amp; Gurmankin 2001). Additionally, certain relevant medical conditions might only become apparent long after the donation. While a system could be put in place for donors to update their medical information, some argue that such a system would likely be too cumbersome for donor-conceived individuals to receive the medical information they need in a timely fashion (McGee, Brakeman, &amp; Gurmankin 2001).
