This is just scary to me. I can't keep from thinking that these doctors are treading into Mengele territory, and yes, I just invoked Godwin's Law. But in this case, I think it's merited.
UPDATE: C&Ler Morris Berg directs us to this article at The Next Hurrah, that claims this story was trumped up by PETA simply out of objection to animal experimentation. More neutral articles on Dr. Roselli's studies (which, as pointed out by several commenters, backs up the position that being homosexual has a biological basis) are here and here.

Scientists are conducting experiments to change the sexuality of "gay" sheep in a programme that critics fear could pave the way for breeding out homosexuality in humans.
The technique being developed by American researchers adjusts the hormonal balance in the brains of homosexual rams so that they are more inclined to mate with ewes.
It raises the prospect that pregnant women could one day be offered a treatment to reduce or eliminate the chance that their offspring will be homosexual. Experts say that, in theory, the "straightening" procedure on humans could be as simple as a hormone supplement for mothers-to-be, worn on the skin like an anti-smoking nicotine patch.
The research, at Oregon State University in the city of Corvallis and at the Oregon Health and Science University in Portland, has caused an outcry. Martina Navratilova, the lesbian tennis player who won Wimbledon nine times, and scientists and gay rights campaigners in Britain have called for the project to be abandoned.
Navratilova defended the "right" of sheep to be gay. She said: "How can it be that in the year 2006 a major university would host such homophobic and cruel experiments?" She said gay men and lesbians would be "deeply offended" by the social implications of the tests.
But the researchers argue that the work is valid, shedding light on the "broad question" of what determines sexual orientation. They insist the work is not aimed at "curing" homosexuality.
Approximately one ram in 10 prefers to mount other rams rather than mate with ewes, reducing its value to a farmer. Initially, the publicly funded project aimed to improve the productivity of herds.
The scientists have been able to pinpoint the mechanisms influencing the desires of "male-oriented" rams by studying their brains. The animals' skulls are cut open and electronic sensors are attached to their brains.
By varying the hormone levels, mainly by injecting hormones into the brain, they have had "considerable success" in altering the rams' sexuality, with some previously gay animals becoming attracted to ewes.
Professor Charles Roselli, the Health and Science University biologist leading the research, defended the project.
He said: "In general, sexuality has been under-studied because of political concerns. People don't want science looking into what determines sexuality.
"It's a touchy issue. In fact, several studies have shown that people who believe homosexuality is biologically based are less homophobic than people who think that this orientation is acquired."
