A Dutch court has approved a request by families seeking DNA tests on the belongings of a late fertility clinic doctor accused of using his own sperm in dozens of cases.
Jan Karbaat is suspected of fathering about 60 children at the centre he ran in Bijdorp, near Rotterdam.
Tests will now be conducted on items seized from his home after his death in April, at the age of 89.
A lawyer for his family said there was no evidence to support the claims.
Jan Karbaat called himself “a pioneer in the field of fertilisation”.
His clinic was closed in 2009 amid reports that he had allegedly falsified data, analyses and donor descriptions and exceeded the permitted number of six children per donor.
At a court hearing last month, a lawyer for the 22 parents and children said that the suspected cases included a client’s child who had brown eyes when the sperm donor was supposedly blue-eyed and a client’s son who physically resembled the doctor.
