In the U.S., an estimated 30,000-60,000 children are born each year through sperm donation, but this number is only an educated guess. Neither the industry nor any other entity in the U.S. is required to report on these vital statistics. Most strikingly, there is almost no reliable evidence, in any nation, about the experience of young adults who were conceived in this way. "My Daddy's Name Is Donor" is the first effort to learn about the identity, kinship, well-being, and social justice experiences of young adults who were conceived through sperm donation.
