So far, the mothers who were impregnated with 3066’s sperm have been frustrated in their attempts to find out more about the man and confirm their suspicions that their children inherited their medical problems from him.
But they have formed a support group of sorts, comparing notes on their youngsters and arming themselves with medical information they might need someday.
Researchers do not know whether autism, a disorder that affects the ability to form normal social relationships and communicate with others, is a hereditary disease or an acquired illness, according to the Autism Society of America. It affects one in 175 children ages 4 through 17, the society said.
The Web site helped Jorgenson find Jenafer Elin, whose 9-year-old son Joshua, another offspring of 3066, is also sensitive to noise and hates wearing clothing with tags. Cheyenne, Joshua and their 7-year-old half-sister Allyson and their mothers met in Fresno, Calif., this summer for a reunion.
"They got along well and they hit it off immediately," said Allyson’s mother, Dawn Warthen of Taneytown, Md. "They referred to each other as brother and sister. They all looked very similar with their blond hair and the girls both had shocking blue eyes."
Donor 3066 – a man of Norwegian and German descent and a member of the Screen Actors Guild – filled out a medical profile and reported only that his paternal grandmother had high blood pressure, Jorgenson said.
"Now I’ve learned more and more history about the other siblings, so you kind of say, `Hey, maybe the donor did know something but didn’t mention it,’" Jorgenson said. She said she called the sperm bank for more information about 3066 and was turned down.
Cappy Rothman, medical director and co-founder of the California Cryobank, said 3066 has been put on "restricted" status – meaning women can still use his sperm, but are warned that problems could arise in their children – because a child fathered by him was diagnosed with what Rothman described only as a "metabolic problem." Rothman said no clients have told the cryobank their child had autism.
Rothman said the sperm bank tests for major infectious illnesses such as hepatitis and HIV, but not more exotic medical conditions, and it is not required by law to do so. The sperm bank relies on donors to fill out medical histories extending back three generations.
As for its policies on privacy, Rothman said it does not disclose its donors’ identities without their consent.
Arthur Caplan, a University of Pennsylvania bioethicist, said the sperm bank field exists "somewhere between the Wild West and chaos," with no regulations regarding privacy or screening for noninfectious diseases.
"The doctors don’t want regulations. The couples who want the treatments don’t want regulations. And politicians don’t want to go in and regulate because it puts them right smack in the middle of discussions of things like embryos," he said.
The mothers who used sperm from 3066 said they want more information from sperm banks, not just for themselves but for other mothers trying to figure out why their child is falling ill or acting differently.
"They want to know: `Why did this happen to my child?’" Jorgenson said.
