THE HAGUE, Netherlands (AP) — 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 Monday that three more people contacted him over the weekend because they suspect they may also have been conceived using the sperm of Dr. Jan Karbaat.
