Dutch fertility doctor secretly used his own sperm to father 49 children

April 12, 2019

The owner of a fertility clinic used his own sperm to father 49 children, according to DNA tests revealed on Friday.

Jan Karbaat died in 2017, and after his death dozens of people came forward to say that they suspected that he had used his own sperm to impregnate their mothers, without their knowledge.

A court case gave permission for materials containing his DNA to be collected and then the 49 Dutch people fought for the right to test their own DNA against these samples.

Tim Bueters, lawyer for the group, has said that he is happy that an end has come to their uncertainty, reports the NOS .

The doctor, who had a clinic in Barendrecht, had recognised 22 children.
