In 2012, a Texas man successfully defended a child support claim brought by the mother of two children who were conceived with sperm he donated. In 2008, another sperm donor, who had regular contact with the children and had agreed to provide some support, lost a case brought by the children's mother for increased support. Now a third sperm donor is being pursued for child support even though the child's mother is not seeking his assistance. These cases all illustrate the importance of seeking legal advice before becoming involved in artificial reproduction.In the most recent case, a man agreed to donate sperm to a lesbian couple that used a do-it-yourself artificial insemination kit to conceive. After the child was born and the couple broke up, the child's biological mother sought public aid for the child in Kansas, where she resides. The state then went after the sperm donor for support, arguing he is the father under state law because a doctor was not involved in the artificial insemination procedure. The case is scheduled for hearing in April.
