A Dutch fertility doctor who used his own sperm to father 49 children, without telling their mothers he was the donor, may have even more children. Ties van der Meer of the Dutch Donor Child Foundation said three more people contacted him over the weekend because they suspect they may also have been conceived using Karbatt’s sperm. DNA tests revealed last week that Karbaat was the biological father of 49 children. In the past, fertility doctors would advise parents not to tell their children they were conceived with the help of donors, he said.
