Ms Rowlette initially dismissed the Ancestry.com test that determined Dr Mortimer was her father, but later found her birth certificate with his signature, the Daily Beast reported.
Mainly, the lawsuit asserts that Mortimer knowingly used his own sperm to impregnate Rowlette's mother.
Before receiving the shocking test results, Ms Rowlette had no clue that her parents had experienced trouble conceiving and had visited Dr Mortimer in the late 1970s. Mortimer said Rowlette's mother, Sally Ashby, had a tipped uterus, and diagnosed Ashby's husband, Howard Fowler, with a low sperm count and low sperm motility.
In the procedure, 85% of Fowler's DNA was mixed with 15% of a donor's DNA.
According to the lawsuit, Ashby and Fowler agreed to do the operation but only if the donor had physical characteristics similar to Fowler - brown hair, blue eyes and over 6 feet tall.
Instead, the doctor, who did not match the donor specifications, used his own sperm for the inseminations - three per month in June, July and August of 1980, according to the lawsuit. They had attended Dr Mortimer's former Idaho Falls clinic for IUI (artificial insemination) during the early 1980s.
"Dr. Mortimer knew that Kelli Rowlette was his biological daughter, but he did not say that to either Ashby or Fowler", according to the papers. "Dr. Mortimer knew Kelli Rowlette was his biological daughter but did not disclose this to Ms. Ashby or Mr. Fowler". When the Ancestry.com DNA test revealed that Rowlette's father was Ashby's fertility doctor, Dr. Gerald E. Mortimer, the family was stunned.

Rowlette, Ms. Ashby, and Mr. Fowler are suing Dr. Mortimer for the charges of Medical Negligence, Failure to Obtain Informed Consent, Fraud, Battery, Intentional Infliction of Emotional Distress, Negligent Infliction of Emotional Distress, Breach of Contract, Consumer Protection Act Violation, Respondeat Superior, and Negligent Supervision.
On May 20, 1981, Ms. Ashby gave birth to Kelli Rowlette (maiden name, Kelli Fowler).
Mortimer remained Ashby's doctor for several years until the she and her husband moved to Washington state.
It wasn't until Rowlette was helping clean up her father's house that she finally discovered her parents' connection to Mortimer. Mortimer apparently thought it was okay to use himself as a donor without telling the couple what he did.
But she is said to have been even more shocked to allegedly discover her real dad was the doctor who they asked for help. "Anyone who takes a test can change their DNA matching settings at any time, meaning that if they opt out, their profile and relationship will not be visible to other customers".
This isn't the first time a male doctor has been accused of using his own sperm in a fertility treatment procedure.
