A Dutch sperm donor has fathered as many as 1,000 children — possibly even thousands more  —  with unsuspecting women around the world, and is continuing to do so despite a court order that he stop, a new documentary reveals.

Jonathan Jacob Meijer was ordered last year to cease donating sperm after it was discovered that he had fathered as many as 600 babies since 2007 in the Netherlands alone, many with women who had hoped their children would have a relationship with their biological father.

The tall, handsome Dutch man with long curly blonde hair often posed as a sperm donor in ads on private donation sites who would keep in touch with the children he fathered. But women were later shocked that their children had hundreds of half siblings fathered by Meijer, which made any kind of normal family life with dad and siblings impossible.

"He wanted to be somewhat involved with the kids, to know how they were doing ... I really wanted my children to have that," a mom identified only as "Vanessa" says on the three-part Netflix docuseries "The Man with 1,000 Kids," which debuts July 3.

"That's all gone now, and it won't ever, ever get better," she added.

Meijer, 41, was ordered to stop donating sperm last year after he was taken to court by a foundation protecting the rights of donor children and by the mother of one of the children.

Yet he's accused of continuing to donate sperm all over the world.

"It's become an addiction for him, he can't stop himself," said another mother of one of Meijer's many kids, who was devastated to learn that there's an entire population of children the size of a small village in the world fathered by Meijer.

"You get one life on this Earth. Why has he chosen to use his charm and his intellect and his creativity in order to try to procreate on a mass scale and deceive all these people?" asked director Josh Allott.
