It has not been unusual for gay and lesbian couples to arrange privately for surrogacy or for a donation of sperm from a friend or third party in order for a couple to inseminate one of the lesbian partners so that they can bring children into their family. A recent case involving the latter method of procreation may result in lesbian partners being forced to use clinics approved for A.R.T. rather than an informal gift from a friend or acquaintance.A Kansas man, William Marotta, donated sperm to a lesbian couple after answering a Craigslist ad placed online by Angela Bauer and Jennifer Schreiner. Bauer and Schreiner were seeking a sperm donor. After exchanging emails and meeting, the three signed an agreement relieving Marotta of any financial or paternal responsibility. The couple accomplished the artificial insemination themselves using a syringe, and Schreiner eventually became pregnant. Late last year, after she and Bauer broke up, because Kansas does not recognise same-sex marriage, Schreiner, who bore the child, was awarded sole custody, Bauer was not liable for child support, and Schreiner applied for Title IV-D benefits. So the state came after Marotta for child support.
