Something in the Way She Smells

Pheromones Enhance Females' Sexual Attractiveness to MalesMarch 21 - When it comes to sexual attraction, new research provides evidence that the nose knows. Women who wore perfume with synthesized female pheromone were more attractive to their male partners, conclude scientists at San Francisco State University. 

Pheromones are odorless chemicals excreted from the body that affect reproductive interactions among both animals and humans. They are picked up by a special organs or tissues in the nose, and then conveyed to regions higher up in the brain.

The new study, appearing in the journal Physiology and Behavior, found that women who had pheromone added to their perfume reported a more than 50 percent increase in sexual attention from men: they were involved in more sexual intercourse, kissing, heavy petting, affection, and slept closer to their partner or date. 

Women wearing perfume with a placebo also experienced an increase in these activities, though not as great as the pheromone group. The authors say this increase can be explained by the effect that results from "just thinking" you are wearing a sexy pheromone. 

"The most highly significant difference between the placebo and the pheromone group was actually sexual intercourse," says Norma McCoy, lead author and professor of psychology at San Francisco State University. "It is clear that there is something that is odorless and is being exuded from reproductive age women — that affects male behavior — that makes the women attractive." 

Pheromones and Attraction  

The pheromone used in the study is what its maker, Athena Institute for Women's Wellness Research, believes is a generic substrate, a substance that when put on someone's skin reacts with that person's own chemistry to achieve its effect.Adds Winnifred Cutler, institute founder and president and a reproductive biologist and co-discoverer of pheromones in humans, "When it works for a woman, it doesn't seem to matter what perfume she wears." 

Research has also shown that significantly more men who wore aftershave with a synthetic version of a male-excreted pheromone engaged in sexual intercourse and sleeping next to their partner than those who wore aftershave with placebo. 

Beyond Sexual Attraction

There is more to pheromones than sexual attraction, according to Cutler."If you divide up the research on pheromones into what type of behaviors are shown to be affected by them, you can organize them into four different classes," says Cutler: mother-infant interaction, territorial marking, reproductive synchrony, and sexual attraction.

While most studies on the topic use animals, there have been intriguing human findings, too. Studies have shown, for instance, that babies as young as three days old are able to distinguish the odor of their mother from that of other nursing mothers. Babies will turn their faces toward lingerie that has been worn by their own mothers — and ignore other women's — when the garments are waved over their heads.

Other research on reproductive synchrony has shown that women living together in dorms or working together have synchronized menstrual cycles. Interestingly, one study of women working in pairs found that women who said they disliked each other did not cycle together. Future Pheromone ResearchIn addition to providing interesting insight into the roots of human behavior, pheromone research may have some therapeutic uses. 

The Athena Institute is currently exploring uses of attractant pheromones to improve social interactions of people who may experience subconscious shunning by others, such as people with cerebral palsy. In addition, infertility groups have expressed interest in doing research on women who are undergoing infertility treatments to see the effect that these chemicals have on the outcome. 

Attractant pheromones may also be useful to women who have undergone hysterectomies. "In women a loss of sexual attraction is frequently experienced after hysterectomy and there is a need for a double blind study to look at the role that pheromones play in that," explains Cutler. These future research projects have the potential to expand the application of pheromones to humans beyond the perfume bottle.

Androstenone & Androstenol

These two pheromones, which surface on the skin of men (and women), occur when chemicals in one's sweat interact with common bacteria. And yes, both of them are believed to influence human attraction.

The difference between them is that androstenol can affect people's impressions of a man's sexual attractiveness, intelligence and confidence.

Androstenone is believed to be the scent of male aggression and dominance. Women are attracted to men who naturally secrete large quantities of these pheromones, and other men tend to avoid them. 

So spray some on, head on out and get your groove on (or stay in with your woman if that's your game instead). The product will remain on your skin for 24 to 48 hours, so long as you don't bathe, thus removing it.

Now you can finally discover if the only thing you're missing is that secret scent that unknowingly attracts people to you. Enjoy the smell of sex.
