Dutch court bans prolific sperm donor from donating again.

A Dutch court has banned a sperm donor, identified as Jonathan M., from donating any more of his sperm after he fathered at least 550 children in the Netherlands and other countries and misled prospective parents about the number of offspring he helped to conceive. The court noted that under Dutch guidelines, sperm donors are allowed to produce a maximum of 25 children with 12 mothers and that the donor lied to prospective parents about his donation history. The court ruled that “the interests of the donor children and their parents outweigh the interest of the donor in continuing to donate sperm to new prospective parents.”
