Sperm donor alleged to have fathered 550 children faces legal action

A Dutch sperm donor is facing legal action to stop him from fathering more children. 

The 41-year-old from The Hague has allegedly fathered at least 550 kids around the world.

A woman who conceived a child in 2018 using his donated sperm is behind the lawsuit along with the Donorkind Foundation, an organisation that stands up for the rights of donor children.

The man - named Jonathan M. in the Dutch press - has donated his sperm to at least 13 clinics in the Netherlands and overseas, according to the foundation. 

Guidelines say one person may donate sperm for up to 25 offspring or for 12 families to prevent incest relations and protect the mental health of donor children.

"If I had known he had already fathered more than a hundred children, I would never have chosen this donor," the mother who launched the proceedings against him said in a statement. 

"When I think about the consequences this can have for my child, I get a feeling of [the] gut and I become insecure about his future: how many more children are added?"

"Going to court is the only way to protect my child," she continued.  

The man was already blacklisted in the Netherlands in 2017 after it emerged that he had more than a hundred donor children. 

The Dutch Society of Obstetrics and Gynaecology (NVOG), at the time, urged all sperm banks and clinics to stop using his sperm immediately. 

Jonathan M. is alleged to have continued donating abroad and through illicit channels. 

The Donorkind foundation claimed the donor reaches out to prospective mothers through social media to offer his sperm under the counter. 

He has allegedly lied about the number of children he has fathered through sperm banks.

According to the foundation's lawyer Mark de Hek, the donor violated agreements
