Dutch court bans prolific sperm donor who deceived parents and fathered over 500 children

A Dutch court has banned a man from donating sperm after he fathered at least 550 children by deceiving prospective parents.
The man misled parents about the number of children he had already fathered and continued donating sperm despite guidelines limiting donors to 25 children.
The court ruled the interests of the donor children and parents outweighed the interest of the donor in continuing to donate.
The man must pay fines if he violates the ban and ask clinics to destroy any remaining sperm samples except those reserved for parents who already used his donations.
Concerns were raised about the possibility of accidental incest between the donor's many biological children.
