The Dutch serial sperm donor recently sued over incest fears says he wants to start a family of his own – with five kids.
Jonathan Jacob Meijer has at least 550 children all over the world.
About 375 live in the Netherlands, 80 in Germany, 35 in Belgium, four in Argentina, and two in Australia.
His fathering spree began in 2007, when Meijer, 42, registered as a sperm donor at 11 clinics and at the Cryos sperm bank.
He also joined Facebook groups for women and couples who want but cannot have kids.
Over the years, Meijer lied to everyone. He told each clinic he would exclusively donate there, and he told each prospective mother he “only” had about 10 children.
When asked by German media why he wants so many kids, Meijer replied: “I want to do something meaningful with my life.”
He added: “Yes, I lied to the women. That was wrong. I wanted to help them.”
Despite this claim, many mothers of children conceived with his sperm have furiously condemned Meijer after finding out about his donation addiction.
Of them, 157 have joined a Facebook support group called “Donorkind 102 JJM”.
When asked by German media about his hundreds of children, Meijer replied: “I like to meet them. But emotionally, they feel more like my nephews and nieces.
“Otherwise, it would be too much for me.”
Meijer himself is one of eight siblings. He has worked as a civics teacher, a mailman, and a cryptocurrency consultant.
The Cryos sperm bank sold his donations for around EUR 1,300 (GBP 1,100) each, but Meijer claims he donates his sperm for free.
He told German media: “I don’t ask for anything, but sometimes I receive EUR 75 (GBP 64), a plane ticket, or a camera as a gift.”
One mother of a child conceived with Meijer’s sperm sued the Dutchman in April, arguing that his actions have increased the risk of incest.
The civil court in The Hague ruled that he is no longer allowed to donate his sperm. If he does so again, he will be fined EUR 100,000 (GBP 85,000).
The complainant was supported by the organisation Donorkind, whose CEO, 44-year-old Ties van der Meer, is himself a donor-conceived child.
Van der Meer, who has conceived 18 children himself via sperm donations, told German media: “What Meijer is doing is irresponsible!
“According to the verdict, he has 550 children. I fear that he wants to set a record and already has 1,000 children today.”
If Meijer really does have 1,000 children, he would rank second after Mongol leader Genghis Khan, who is said to have fathered up to 2,000 children.
Incredibly, Meijer continues to donate sperm, but, he claims, only to women who already have a child from him and want another, which the recent verdict allows for.
Earlier this month, he “helped” a Dutch woman, and this week, he will fly to Serbia and Italy to visit the mothers of some of his children.
Meijer told German media he wants to raise kids of his own one day. He said: “I want to start a family, dream of having five children.”
