Massadonor S. signs contract prohibiting him from donating sperm anymore

A 44-year-old man, S., has made agreements with Stichting Donorkind regarding his sperm donations, which include destroying stored sperm and ceasing communication with prospective parents. Failure to comply may result in financial penalties, though specific amounts are undisclosed. S. has fathered at least 121 children, with his own claim being 199, and misled parents about the number of his donations. While regulations allow a maximum of twelve families per donor, S. continued to donate sperm privately, raising concerns about the implications of having numerous biological siblings.
