Gay Men Respond Differently To Pheromones
Gay Men Respond Differently to Pheromones
Monday, May 9, 2005 10:09 PM EDT The Associated Press By RANDOLPH E. SCHMID Gay men's brains respond differently from those of heterosexual males when exposed to a sexual stimulus, researchers have found. The homosexual men's brains responded more like those of women when the men sniffed a chemical from the male hormone testosterone. "It is one more piece of evidence ... that is showing that sexual orientation is not all learned," said Sandra Witelson, an expert on brain anatomy and sexual orientation at the Michael G. DeGroote School of Medicine at McMaster University in Ontario, Canada. Witelson, who was not part of the research team, said the findings clearly show a biological involvement in sexual orientation. The study, published in Tuesday's issue of Proceedings of the National Academy of Sciences, was done by researchers at the Karolinska Institute in Stockholm, Sweden. They exposed heterosexual men and women and homosexual men to chemicals derived from male and female sex hormones. These chemicals are thought to be pheromones _ molecules known to trigger responses such as defense and sex in many animals. Whether humans respond to pheromones has been debated, although in 2000 American researchers reported finding a gene that they believe directs a human pheromone receptor in the nose. The Swedish study was one of a series looking at whether parts of the brain involved in reproduction differ in response to odors and pheromones, lead researcher Ivanka Savic said. The brains of different groups responded similarly to ordinary odors such as lavender, but differed in their response to the chemicals thought to be pheromones, Savic said. The Swedish researchers divided 36 subjects into three groups _ heterosexual men, heterosexual women and homosexual men. They studied the brain response to sniffing the chemicals, using PET scans. All the subjects were healthy, unmedicated, right-handed and HIV negative. When they sniffed smells like cedar or lavender, all of the subjects' brains reacted only in the olfactory region that handles smells. But when confronted by a chemical from testosterone, the male hormone, portions of the brains active in sexual activity were activated in straight women and in gay men, but not in straight men, the researchers found. The response in gay men and straight women was concentrated in the hypothalamus with a maximum in the preoptic area that is active in hormonal and sensory responses necessary for sexual behavior, the researchers said. And when estrogen, the female hormone was used, there was only a response in the olfactory portion of the brains of straight women. Homosexual men had their primary response also in the olfactory area, with a very small reaction in the hypothalamus, while heterosexual men responded strongly in the reproductive region of the brain. Savic said the group is also doing a study involving homosexual women but those results are not yet complete. In a separate study looking at people's response to the body odors of others, researchers in Philadelphia found sharp differences between gay and straight men and women. "Our findings support the contention that gender preference has a biological component that is reflected in both the production of different body odors and in the perception of and response to body odors," said neuroscientist Charles Wysocki, who led the study. In particular, he said, finding differences in body odors between gay and straight individuals indicates a physical difference. It's hard to see how a simple choice to be gay or lesbian would influence the production of body odor, he said. Wysocki's team at the Monell Chemical Senses Center studied the response of 82 heterosexual and homosexual men and heterosexual and homosexual women to the odors of underarm sweat collected from 24 donors of varied gender and sexual orientation. They found that gay men differed from heterosexual men and women and from lesbian women, both in terms of which body odors gay men preferred and how their own body odors were regarded by the other groups. Gay men preferred odors from gay men, while odors from gay men were the least preferred by heterosexual men and women and by lesbian women in the study. Their findings, released Monday, are to be published in the journal Psychological Science in September. The Swedish research was funded by the Swedish Medical Research Council, the Karolinska Institute and the Magnus Bergvall Foundation. Wysocki's research was supported by the Monell Center. ___

Be it gay, straight, male or female, I'm not a big fan of body odor in general.
 Still an interesting read though...

This is no surprise to me. I have been yammering about it with my friends forever. In fact, I have hung out with guys before simply because the way they smelled practically made me drunk. And I am not talking about cologne. Cologne and perfume are both vile.
I doubt they will isolate specific chemicals with this study - the chemical makeup of each person is drastically different. However, I am certain half my brain was lit up like Las Vegas when the guy I mentioned got within 5 feet of me. And the scent women have ? Makes me twitchy, claustrophobic, and irritable.

Cologne is sort of gross - if you don't know how to wear it. My friends and I used to have a joke - because seriously like EVERY gay man in the Las Cruces/El Paso area wore the same cologne - or knock offs of similar colognes...they all smelled the same anyway.....so now everytime I smell that scent, I stop and say..."I smell gay man!" It's not meant to be offensive....but I can't smell that cologne (or anything similar) without associating it with gay men

Ugh, the gay perfume mafia. That is SO 80's. Obsession, Polo, Drakkar Noir. Somebody save me from it all. I am thankful that it isn't hip anymore. I am a total cologne Nazi. Won't date a guy who wears it, let alone sleep with him. I have asked one nighters to leave because of it I'd prefer a cigar smoker.

lol...well "gay man" isn't Obsession, Polo or Drakkar Noir  I know that - but I also can't tell you what exactly it is.....some New Mexico/El Paso skank scent lol....and though it may not be hip anymore many a gay man down that way still put us through the hell of having to smell them...Well it's not al gay men....I work with a man who apparently has to wear an entire bottle of heinous cologne every damn day. It makes me sick - he leave a scent trail everywhere he goes and it takes forever to go away...it's SO gross..... Conversly I also hate it when women wear too much perfume - it's just disgusting...

 That's great! Anyway, thanks for posting this, Joe. Nice to see. I wonder when someone's going to produce some evidence in relation to lesbians specifically? Of course, there might be some already and I just haven't seen it.

To put the cherry on the cake, I am also allergic to a lot of of things in perfume. The worst offenders I run across are casting directors, who generally can be smelled when they are in a car next to you on the freeway. Unfortunately, I have had offices next to them frequently. Once, this poor, haggard crank of a woman I worked by wore so much Opium or Poison, that I literally could smell her when she walked into the building. It got so bad that eventually within five minutes of her arrival every morning I had a headache and my eyes were watering. I asked her to please tone it down and she never spoke to me again. Her assistant said she didn't even smell it. Her sense of smell had been completely eradicated by her three pack a day Virginia Slims habit. On top of that, she looked like one of the trees from the Wizard of Oz. Makes me shudder just thinking about it.
