"Screening policies in the human gamete industry reflect larger cultural assumptions that pathologize difference. In my research on both sperm donation in the 1990s up to my current work on egg donation, I have discovered there are a number of reasons a prospective sperm or egg provider may be rejected: too short, too tall, overweight, “socially inappropriate,” not having the “right motivations,” not attractive enough, a variety of “health reasons,” possibly even religion or ethnicity, and so on. The reasons for rejecting a potential donor are often unspoken."
