Abstract

In this paper it is argued that the overwhelming majority of gamete donors are amongst those who treat decisions about bringing children into existence too lightly. The argument proceeds through the following stages. 1) People have a presumptive responsibility for rearing children who result from their gametes. 2) The responsibility people have to rear their offspring is a responsibility not merely to provide a minimum of care, but also to attend to the details of nurturing children and fostering their flourishing. 3) Gamete donors transfer their responsibilities for raising their genetic offspring to those who will raise it. 4) Responsibilities for rearing children are weighty ones. 5) Treating weighty responsibilities too lightly is morally wrong. 6) Gamete donors' decisions to transfer their responsibilities for rearing their offspring to others, almost always involves treating parental responsibilities too lightly. 7) Therefore, gamete donation is almost always morally wrong.
