According to The Sun UK, Kelli Rowlette reportedly took legal action against reproductive specialist Dr Gerald E Mortimer after he was revealed as her DNA match through the site.
The lawsuit claims the doctor was aware he used his own sperm to impregnate Rowlette’s mum when she and her husband went to him for help in the early 1980s, the Daily Beast reported.
Rowlette was reportedly unaware her parents had turned to artificial insemination after struggling to conceive.
But she is said to have been even more shocked to allegedly discover her real dad was the doctor who they asked for help.
To increase their chances of fertility, the couple reportedly agreed to mix the husband’s sperm with other matching donors, noting they preferred college students more than six feet tall.
But the doctor used his own sperm to impregnate Rowlette’s mother, the lawsuit claims.
Rowlette accuses Mortimer, who later delivered her, of making false statements to her parents about following their wishes and never revealing he was the biological father.
The complaint claims: “Dr Mortimer fraudulently and knowingly concealed his use of his own genetic material in the procedure.
“Dr Mortimer knew Kelli Rowlette was his biological daughter but did not disclose this.”
She is reported to have initially dismissed the Ancestry.com test that determined Mortimer was her father.
But Rowlette later found her birth certificate with his signature, it is claimed.
She is now reportedly suing the doctor, claiming medical negligence, battery and fraud.
