Abstract

The vast majority of gamete donations worldwide are made anonymously, and in some countries, including Spain, France, and Denmark, the anonymity of donors is explicitly protected by law. Nonetheless, a growing number of countries have called into question the morality of such practices and are enacting laws allowing children access to identifying information about their gamete donor. A significant reason for the growing legislative support for nonanonymous gamete donations is the belief that donor‐conceived children have a fundamental moral right to know their genetic origins and that the right should be legally protected. A variety of factors, such as the increasing number of children born by means of gamete donation, advances in genetic science and technology that make it easy to discover the identity of a person's genetic parents, and the widespread belief that genetic information is important for protecting people's health, have made this alleged right quite salient, even leading some to challenge the ethical appropriateness of gamete donation practices altogether. Often, however, this right is assumed rather than explicitly justified. The purpose of this paper is to call into question the ethical justifications that are often thought to ground a right to know one's genetic origins.Proponents of a right to know this information usually argue that such a right protects at least three vital interests: the interest of donor‐conceived people in having strong family relationships, their health interests, and their interest in forming a healthy identity. These different interests might be protected by different aspects of the right to know one's genetic origins: knowing one's mode of conception, accessing medically relevant information, and accessing identifying information about one's genetic parents. I will discuss each of these interests and explore whether and how they might be set back by an individual's lack of access to information about his or her genetic parentage. I will also evaluate whether donor anonymity policies are, as many of their opponents argue, morally impermissible because they fail to protect these important interests.
