A woman has filed a lawsuit against a doctor in the US state of New York after her daughter made a shocking discovery following the result of a commercial DNA test.
The daughter of New Jersey woman Bianca Voss just wanted to know more about her family history but ultimately discovered her father was a retired doctor who her family is now accusing of "medical rape".
Ms Voss, 75, says the doctor secretly used his own sperm to impregnate her nearly 40 years ago, in an act of deceit that resulted in the birth to her daughter, NBC reported.
In the federal lawsuit, Ms Voss claimed she paid a New York doctor named Dr Martin Greenberg $100 to secure an anonymous sperm donor for her in 1983.
"Without Plaintiff’s knowledge or consent, Greenberg used his own sperm to impregnate her, rather than, as promised, use an anonymous donor from a sperm bank," the lawsuit says.
"Plaintiff learned of Greenberg’s betrayal only recently, after her daughter obtained her DNA profile from 23&me.com."
The suit says Ms Voss has been left "shocked and devastated by Greenberg’s disgusting abuse of power" after finding out the alleged truth.
She was living in Manhattan at the time when she decided to have a child through an anonymous sperm donor. Her daughter, Roberta Voss, was born in 1984.
A lawyer for Ms Voss, Jason Kane, said the alleged act of deception amounts to an illegal act.
"Some people call this horrific act 'medical rape'. But regardless of the name, Greenberg's heinous and intentional misconduct is unethical, unacceptable and illegal," he said.
According to NBC, the retired Greenberg now lives in Florida. He has not responded to media requests for comment.
Speaking to reporters on Tuesday (local time), Ms Voss recalled the discussion she remembers having with her doctor all those years ago.
"I wanted someone anonymous," she told reporters.
"He did say, 'Do you mind the donor is Jewish?' And I said 'no' and that was it. I kind of thought it might be a medical student from the hospital, but that was it. And then he asked me for the check for $100 to cover the donor, his inconvenience."
Roberta Voss said after seeing photos or her apparent father, she now sees his face "every time I look in the mirror".
"I’m haunted by the idea of a medical rapist being my father and the enormous deceit that went into my conception," she said, according to the New York Post.
