If you're planning to donate sperm in Kansas, you may want to do it through a doctor.
That's one message from the case of William Marotta of Topeka. In 2009, he noticed a Craig's List advertisement from a lesbian couple, also in Topeka, seeking donated sperm.
"Intrigued" by the ad, he agreed to donate and says he delivered three cupfuls of his sperm -- gratis -- to the women, one of whom gave birth to a daughter.
"I donated genetic material, and that was it for me," he told CNN affiliate WIBW.
Or so he thought. That changed when the parents separated and one of the women stopped working because of illness and applied to the state for help, he said. The state contacted Marotta for child support.
Kansas officials were not persuaded by what Marotta says were agreements he signed before making his donations that he would assume no financial responsibility for the child, who is now 3 years old.
The Kansas Department for Children and Families said any agreement would not apply because a physician did not perform the insemination, which Marotta said was news to him.
"I didn't know that there was no doctor involved," Marotta said Friday.
His lawyer, Ben Swinnen, accused the state, where same-sex marriage is not legal, of being politically motivated in its pursuit of $6,000 from his client.
"The cost to the state to bring this case far outweighs any benefit the state would get," he said.
