The first Facebook message arrived when Heather Woock was packing for vacation, in August 2017. It was from a stranger claiming to be her half sibling. She assumed the message was some kind of scam.
The people now sending her messages said they were [fertility doctor Donald] Cline’s secret biological children. They said their parents had also been treated by Cline. They said that decades ago, without ever telling his patients, Cline had used his own sperm to impregnate women who came to him for artificial insemination.
A story began to emerge from the DNA, but it contradicted the one Cline had told his patients. He’d said the donors he used were medical residents. He’d said he used each donor for only three successful pregnancies. But 23andMe showed that he’d used one donor at least eight times, and the birth years of the resulting children ranged from 1979 to 1986. Medical residencies last only a few years. What resident would be around to donate sperm for that entire seven-year period?
Cline has admitted to using his own sperm about 50 times, which is about the number of children who have been identified through DNA. More may be out there, though.
