This is a very interesting article in the Washington Post on embryo adoptions in the United States. Here are a couple of salient paragraphs from the piece:
Fertility clinics across the country, according to the most recent data available, held about 400,000 frozen embryos as of May 2003. Patients had reserved 88 percent of them for their own future use, and they had earmarked about 3 percent for medical research. Two percent -- or about 9,000 embryos -- were available for donation to other couples, according to Sean Tipton, director of public affairs at the American Society for Reproductive Medicine, which collected the data.
When the Brinkmans ran into fertility problems, they first tried in vitro fertilization themselves, unsuccessfully. They also thought about a conventional adoption. But because they wanted to experience a pregnancy, Donielle Brinkman said, they turned to Nightlight Christian Adoptions of Fullerton, Calif., and its "Snowflakes" program, a name intended to emphasize that every embryo is unique.
More than half of U.S. fertility clinics allow clients to donate embryos to other couples anonymously. Nightlight, which has received more than $800,000 in grants from the U.S. Department of Health and Human Services to promote embryo adoptions, is one of only a few agencies that treat embryos exactly like infants.
For a fee ranging from $4,000 to $5,600, it arranges "open" adoptions in which the genetic and adoptive parents are matched according to detailed preferences and given an opportunity to get to know each other. Donielle Brinkman said that she did not want to make the genetic family's identity public, but that they have exchanged photographs, phone calls and information over the Internet.
It's worth reading the whole column.
