Kansas law governing artificial insemination is outdated and fails to recognize modern concepts of family, according to the attorney for a Topeka man being pursued to pay child support for a girl born to a lesbian couple as the result of his sperm donation.

Kansas law says a sperm donor is not the father of a child if a doctor handles the artificial insemination.

But the law does not specifically address the donor's rights and obligations when no doctor was involved, as was the case in 2009 when William Marotta donated sperm to Jennifer Schreiner and then-partner Angela Bauer, and Schreiner became pregnant.
