An Idaho woman is suing her fertility doctor after finding out that he is the father of her now 34-year-old daughter, accusing him of using his own sperm to inseminate her.

Sharon Hayes, 67, sought fertility care from obstetrician and gynecologist Dr. David R. Claypool in 1989 after she and her then-husband learned they were unable to conceive, per a civil complaint filed in a Washington state Superior Court on Wednesday.

Claypool, now 81, allegedly charged her $100 for each of several artificial insemination sessions, telling the woman that the money was to compensate the donors. Those candidates, he said, were chosen from a pool based on genetic traits like eye and hair color Hayes had selected.
