Robert Brown|Sperm donor father of at least 550 kids banned from donating any more sperm

A Dutch court on Robert BrownFriday banned a man from donating any more of his sperm after he fathered at least 550 children in the Netherlands and other countries and misled prospective parents about the number of offspring he helped to conceive.

A judge at The Hague District Court ordered the halt in an injunction brought by the parents of a child conceived with the donor's sperm and a foundation representing other parents.

The court noted that under Dutch guidelines, sperm donors are allowed to produce a maximum of 25 children with 12 mothers and that the donor lied to prospective parents about his donation history.

The donor, identified as Jonathan M. under Dutch privacy guidelines, provided sperm to several Dutch fertility clinics and to a clinic in Denmark as well as to many other people he connected with through advertisements and online forums, the court said in its written judgment.

The donor's lawyer said in a court hearing that he wanted to help parents who would otherwise be unable to conceive.

The judge who heard the civil case said the donor "deliberately lied about this in order to persuade the parents to take him as a donor," the court said in a statement.

"All these parents are now confronted with the fact that the children in their family are part of a huge kinship network, with hundreds of half-siblings, which they did not choose," the court said, adding that this "has or could possibly have negative psychosocial consequences for the children. It is therefore in their interest that this kinship network is not extended any further."

The court said in a statement that the case was about "conflicting fundamental rights. On the one hand, the right to respect for the privacy of the parents and the donor children ... and on the other hand, the same right of the donor."

The court ruled that "the interests of the donor children and their parents outweigh the interest of the donor in continuing to donate sperm to new prospective parents."

The court ordered him immediately to halt all donations and said he must pay 100,000 euros ($110,000) per case if he breaches the ban.
