Despite being banned from donating to fertility clinics in the Netherlands in 2017, he continued to donate sperm online and abroad. As a result of his actions, a court in The Hague has ordered him to desist from donating again or he could face a fine of over €100,000 (£88,000).
The court has also ordered him to provide a list of all the clinics he used and instruct them to destroy his sperm. Jonathan was accused of misleading hundreds of women by fathering more than the number of children allowed under Dutch clinical guidelines. The guidelines specify that a donor should not father more than 25 children in 12 families and limit the number of times they donate sperm to reduce the possibility of siblings having children together unwittingly.
