An Arkansas couple is suing a doctor and a hospital after the wife became pregnant and miscarried, although her husband had undergone a vasectomy.

The lawsuit claimed that Dr. Michael F. McGehee, employees of Mercy Health System of Northwest Arkansas and others caused Mindy Hill physical and emotional distress during her pregnancy by suggesting that she had been unfaithful to her husband and by insisting that he most likely wasn't the father because he had been sterilized.

The lawsuit says the defendants' actions put stress on the marriage and Mindy Hill suffered a miscarriage in February 2007. The suit said a paternity test revealed a 99.999 percent chance that her husband, Brady Hill, was the father.

The Rogers couple also name as defendants Northwest Health System of Arkansas, Garrett Goss Clinic and John Does 1 through 45.

The Hills sued for negligence and defamation, and are seeking unspecified monetary damages.
