If Erica Witt were a man, she would have just as much right to a daughter conceived via artificial insemination as her spouse.

"I believe this is a situation where (Erica Witt) has no biological relationship with this child, has no contractual relationship with this child," Fourth Circuit Court Judge Greg McMillan ruled.
