GRAND JUNCTION, Colo. (AP) — A family has filed a lawsuit alleging that a Colorado fertility doctor used his own sperm instead of that of an anonymous donor to impregnate a woman without her knowledge or consent.

KUSA-TV reports that the lawsuit contends Dr. Paul Jones of Grand Junction committed fraud by using his own sperm to artificially inseminate Cheryl Emmons, allowing her to give birth to two daughters in 1980 and 1985, respectively.

The suit contends the daughters discovered they shared Jones’ DNA with a number of strangers this year. It alleges negligence, fraud and other causes of action and seeks damages in a civil trial.

Attorneys for Jones and for Women’s Health Care of Western Colorado, where he practiced, didn’t immediately respond Tuesday to telephone messages seeking comment on the suit.
