Dr. Charles Roselli set out to discover what makes some sheep gay. Then the news media and the blogosphere got hold of the story.
Roselli, a researcher at the Oregon Health and Science University, has searched for five years for physiological factors that might explain why about 8 percent of rams seek sex exclusively with other rams instead of ewes.

These sheep are used in a study of sexual orientation that has provoked a torrent of outrage from animal-rights advocates, gay activists and ordinary citizens.

The goal, he says, is to understand the fundamental mechanisms of sexual orientation in sheep. Other researchers might some day build on his findings to seek ways to determine which rams are likeliest to breed, he said.
But since last fall, when People for the Ethical Treatment of Animals started a campaign against the research, it has drawn a torrent of outrage from animal-rights activists, gay advocates and ordinary people around the world – outrage based, Roselli and colleagues say, on a bizarre misinterpretation of what the work is about.
The story of the gay sheep became a textbook example of the distortion and vituperation that can result when science meets the global news cycle.
The news media storm reached its zenith in December when The Sunday Times in London published an article under the headline “Science Told: Hands Off Gay Sheep.” It asserted, incorrectly, that Roselli had worked successfully to “cure” homosexual rams with hormone treatments and added that “critics fear” the research “could pave the way for breeding out homosexuality in humans.”
Martina Navratilova, the tennis star who is both openly gay and a PETA ally, wrote in an open letter that the research “can only be surmised as an attempt to develop a prenatal treatment” for sexual conditions.
The controversy spilled into the blog world, with attacks on Roselli, his university and Oregon State University, which also is involved in the research. PETA began an e-mail campaign that the universities say resulted in 20,000 protests, some with language such as “You are a worthless animal killer and you should be shot,” “I hope you burn in hell,” and “Please, die.”
The news coverage, which has been heaviest in England and Australia, focused on smirk and titillation – and, of course, puns. Headlines included “Ewe Turn for Gay Rams on Hormones” and “He's Just Not That Into Ewe.”
The other side
In recent weeks, the tide has begun to turn, with Roselli and Jim Newman, an Oregon Health and Science publicist, saying they have been working to correct the record in print and online. The university has sent responses to senders of each PETA-generated e-mail message.
Roselli, whose research is supported by the National Institutes of Health and is published in leading scientific journals, insists that he is as repulsed as his critics by the thought of sexual eugenics in humans. He said human sexuality is a complex phenomenon that could not be reduced to interactions of brain structure and hormones.
On blogs where attacks have appeared, the researchers point out that many of the accusations, like The Sunday Times' assertion the scientists implant devices in the brains of the sheep, are simply false.
The researchers acknowledge that the sheep are killed in the course of the research so their brain structure can be analyzed, but they say they follow animal welfare guidelines to prevent suffering.
Roselli and Newman have persuaded some prominent bloggers, including Andrew Sullivan, the journalist who writes an online column for Time, to correct postings that had uncritically quoted The Sunday Times' article.
Navratilova, who also received a response from the university, said she remained unconvinced.
“The more we play God or try to improve on Mother Nature, the more damage we are doing with all kinds of experiments that either have already turned or will turn into nightmares,” she wrote in an e-mail reply to a reporter's query. “How in the world could straight or gay sheep help humanity?”
In an interview, Shalin Gala, a PETA representative working on the sheep campaign, said controlling or altering sexual orientation was a “natural implication” of the work of Roselli and his colleagues.
Gala, who asked that he be identified as openly gay, cited the news release for a 2004 paper in the journal Endocrinology that showed differences in brain structure between homosexual and heterosexual sheep.
The release quoted Roselli saying the research “also has broader implications for understanding the development and control of sexual motivation and mate selection across mammalian species, including humans.”
Newman, who wrote the release, said the word “control” was used in the scientific sense of understanding the body's internal controls, not in the sense of trying to control sexual orientation.
“It's discouraging that PETA can pick one word, try to add weight to it or shift its meaning to suggest that you are doing something that you clearly are not,” he said.
Human implications?
Roselli said merely mentioning possible human implications of basic research was wildly different from intending to carry the work over to humans.
Mentioning human implications, he said, is “in the nature of the way we write our grants” and talk to reporters. Scientists who do basic research find themselves in a bind, he said, adding, “We have been forced to draw connections in a way that we can justify our research.”
As for whether the deaths of the sheep are justified, he said, “Why would you pick on a guy who's killing maybe 18 sheep a year, when there's maybe 4 million killed for food and clothing in this country?”
Paul Root Wolpe, a professor of psychiatry at the University of Pennsylvania and a senior fellow at the school's Center for Bioethics, said that although he supported Roselli's research, “I'm not sure I would let him off the hook quite as easily as he wants to be let off the hook.”
By discussing the human implications of the research, even in a somewhat careful way, Roselli “opened the door” to the reaction, Wolpe said, and “he has to take responsibility for the public response.”
If the mechanisms underlying sexual orientation can be discovered and manipulated, Wolpe continued, then the argument that sexual orientation is based in biology and is immutable “evaporates.”
The prospect of parents' being able to choose not to have children who would become gay is a real concern for the future, Wolpe said. But he added, “This concern is best addressed by trying to change public perceptions of homosexuality rather than stop basic science on sexuality.”
