Traditionally the criteria for selecting a sperm donor generally were good looks, height, education, athletic ability and a whole host of others that an individual might desire. Modern technology like online registries and DNA tests have added a new criterion for some; how many children has this donor produced. Sperm donation in the U. S. is largely unregulated although there …
