A Dutch court on Friday banned the father of at least 550 children from donating his sperm to future parents. The "mass donor", Jonathan M., 41, according to Dutch media, risks having to pay 100,000 euros every time he breaks the ban.

The court said it was "plausible enough" that the expansion of the huge kinship network would have negative psychosocial consequences for the children. The Netherlands has already been hit by other fertility scandals. In 2020, a gynecologist was charged, after his death, of fathering at least 17 children.
