A woman who was fired by the Catholic school system in Wisconsin after using in vitro fertilization to become pregnant has a hearing Friday before an administrative law judge.

Kelly Romenesko filed a discrimination complaint against her old employers, Appleton Catholic Educational System.

She then appealed after an investigator from the Wisconsin Department of Workforce Development upheld the firing.

Romenekso's attorney says school administrators claim she violated a provision of her employment contract by not acting in accordance with Catholic doctrine.

Catholic teaching holds that in vitro fertilization is morally wrong because it replaces the "natural" conjugal union between husband and wife.

Romanesko says the eggs and sperm used were hers and her husbands and that no embryos were destroyed.
