A foundation representing the interests of donor children and Dutch parents raised a civil case which brought the decision.
A Dutch court on Friday ordered a man who judges said had fathered between 500 and 600 children around the world to stop donating sperm.
The 41-year-old Dutchman, identified by de Telegraaf newspaper as Jonathan Meijer, was forbidden to donate more semen to clinics, the court ruling said. He could be fined 100,000 euros ($110,000) per infraction.
The court also ordered Meijer to write to clinics abroad asking them to destroy any of his semen they have in stock, except doses reserved for parents who already had children by him.
