ATLANTA — He was good on paper: Eloquent, mature, healthy and smart to boot.

That’s why Angela Collins and Margaret Elizabeth Hanson say they chose Donor 9623 to be the biological father of their child.

Then last June, almost seven years after Collins gave birth to a son conceived with his sperm, they got a batch of emails from the sperm bank that unexpectedly – and perhaps mistakenly – included the donor’s name. That set them on a sleuthing mission that quickly revealed he is schizophrenic, dropped out of college and had been arrested for burglary, they said in a lawsuit filed March 31 in Atlanta.

On top of that, the photo of him they’d seen had been altered to remove a large mole on his cheek, the suit says.

Collins and Hanson said the Atlanta sperm bank promoted the donor’s sperm, saying it came from a man with an IQ of 160, an undergraduate degree in neuroscience and a master’s degree in artificial intelligence, who was pursuing a Ph.D. in neuroscience engineering.

The women, who live in Ontario, Canada, sued Xytex Corp., its parent company, sperm bank employees and the man they say was the misrepresented donor – the biological father of at least three dozen children, according to the lawsuit.

The AP is not identifying the donor because it was unable to verify all the claims in the lawsuit.

The donor had a medical exam, provided extensive personal information, said he had no physical or medical impairments and provided photos of himself, according to Xytex.

The case shines a spotlight on an industry that has existed for decades but remains loosely regulated. U.S. Food and Drug Administration requirements for screening sperm donors are limited to screening for contagious or infectious diseases, such as syphilis or HIV. They don’t require genetic testing.
