"A Kansas sperm donor who tried to help a lesbian couple by making his donation five years ago has found himself caught in the middle of a child support case and is now asked by the state to pay child support. William Marotta says he signed documents waiving his parental rights, but Shawnee County District Court Judge Mary Mattivi disagrees. Marotta is ordered to pay child support because he failed to conform to Kansas law, which states that a licensed physician must be involved in an artificial insemination process. Documents show that the lesbian couple performed the artificial insemination at home with Marotta’s donated sperm. Marotta told CNN affiliate WBW, β€œI donated genetic material, and that was it for me.”"
