Do Pheromones Play Role In Your Sexual Life
If you've never heard of pheromones it is time to learn about the part they play in your sex life. The concept of a human pheromone, or sexual scent of attraction, has been debated and researched for years.
Using a brain imaging technique, Swedish researchers have shown that homosexual and heterosexual men respond differently to two odors that may be involved in sexual arousal, and that the gay men respond in the same way as women. The new research may open the way to studying human pheromones, as well as the biological basis of sexual preference.
A pheromone is any chemical or mixture of chemicals produced by a living organism that transmits a message to other members of the same species. The term "pheromone" is usually used for sexual attractants. There are some other pheromones - they act as signals for alarm and defense, territory and trail-marking, and social regulation and recognition. Pheromones are now being used in insect control, for example as bait to attract males to field traps or, in very high concentrations, to disorient insects and prevent mating.
After long dismissing the search for a human pheromone as folly, scientists have begun to take a second look at how human body odor influences sexual attraction. The magic scent is not only a romantic elixir but the aromatic effluence of our immune system. The only trouble is we don't give it half a chance.
Although it's now clear that pheromones exist, the way our body processes them has yet to be well determined. Animals have a vomeronasal organ (VNO), which perceives the substance and then leads them to mate. Some anatomists don't think humans have a VNO; others think they've found pits inside our nostrils that might be VNOs, but may not work.
Pheromones in humans are believed to be produced by the apocrine glands. These glands become functional after reaching puberty, which could explain why most people develop an attraction for others at that time. Pheromones could also be the reason why a person can sense "chemistry", or feel an instant attraction or dislike when first meeting someone.
The Swiss researchers found that women taking oral contraceptives (which block conception by tricking the body into thinking it's pregnant) reported reversed preferences, liking more the smells that reminded them of home and kin. Since the Pill reverses natural preferences, a woman may feel attracted to men she wouldn't normally notice if she were not on birth control--men who have similar MHC profiles.
Dr. Cutler's original studies in the '70s showed that women who have regular sex with men have more regular menstrual cycles than women who have sporadic sex. Regular sex delayed the decline of estrogen and made women more fertile. This led the research team to look for what the man was providing in the equation. By 1986 they realized it was pheromones.
When you're looking for the man or woman of your dreams, unsuspecting pheromones in your body scent are most likely playing a large and very clever role in mate attraction. According to an article in "Psychology Today," how our body odors are perceived as pleasant and sexy to another person is a highly selective process. We usually smell best to a person whose genetically based immunity to disease differs most from our own. This could benefit you in the long run, making for stronger, healthier children.
The alluring chemical scent that young women give off to attract men seems to provide the same effect for post-menopausal women. When the scientists added the scent, a pheromone, to perfume used by older women, their romantic lives seemed to improve, the researchers wrote in New Scientist magazine. The study was also published in the Journal of Sex Behavior. Study leader Joan Friebely and her colleagues applied the test to 44 post-menopausal women. Those who used the treated perfume found their partners to be more affectionate than those who used the normal perfume.
