This is a sticky situation.
Today there are 150 children, all conceived with sperm from one donor, in this group of half siblings, and more are on the way. “It’s wild when we see them all together — they all look alike,” said Ms. Daily, 48, a social worker in the Washington area who sometimes vacations with other families in her son’s group.
As more women choose to have babies on their own, and the number of children born through artificial inseminationincreases, outsize groups of donor siblings are starting to appear. While Ms. Daily’s group is among the largest, many others comprising 50 or more half siblings are cropping up on Web sites and in chat groups, where sperm donors are tagged with unique identifying numbers.
Now, there is growing concern among parents, donors and medical experts about potential negative consequences of having so many children fathered by the same donors, including the possibility that genes for rare diseases could be spread more widely through the population. Some experts are even calling attention to the increased odds of accidental incest between half sisters and half brothers, who often live close to one another.
And it seems there are not too many laws to govern these donations.
Critics say that fertility clinics and sperm banks are earning huge profits by allowing too many children to be conceived with sperm from popular donors, and that families should be given more information on the health of donors and the children conceived with their sperm. They are also calling for legal limits on the number of children conceived using the same donor’s sperm and a re-examination of the anonymity that cloaks many donors.
“We have more rules that go into place when you buy a used car than when you buy sperm,” said Debora L. Spar, president of Barnard College and author of “The Baby Business: How Money, Science and Politics Drive the Commerce of Conception.” “It’s very clear that the dealer can’t sell you a lemon, and there’s information about the history of the car. There are no such rules in the fertility industry right now.”
Although other countries, including Britain, France and Sweden, limit how many children a sperm donor can father, there is no such limit in the United States. There are only guidelines issued by the American Society for Reproductive Medicine, a professional group that recommends restricting conceptions by individual donors to 25 births per population of 800,000.
No one knows how many children are born in this country each year using sperm donors. Some estimates put the number at 30,000 to 60,000, perhaps more. Mothers of donor children are asked to report a child’s birth to the sperm bank voluntarily, but just 20 to 40 percent of them do so, said Wendy Kramer, founder of the Donor Sibling Registry.
