Have you ever wondered how different species know when to mate and who to mate with? How can they tell the difference between someone of the same sex, much less whether another organism is of the same species? This can be answered by chemical signals known as pheromones. Pheromones are unique and highly specific chemical signals produced by an organism that signals its presence to other members of the same species. Each organism have different pheromones they release during mating that helps them to identify each other and start the process of mating. Pheromones come not only in forms of sex attractants, but also as alarm pheromones, aggregation pheromones, and dispersion pheromones.

How do we know that such a chemical exists in organisms? In 1956, German scientists were able to identify the first ever pheromone in silkworm moths. After 20 years of research and over half a million female moths later, they were able to extract a peculiar compound from certain glands located on the tip of the abdomen. When even a small amount of this substance was exposed to male moths, they would begin to beat their wings madly in a flutter dance.

This indicated that they had detected the powerful sex attractant from the females that caused this type of behavior. After extracting extraneous matter and purifying the substance, scientists ended up with the first ever chemically pure pheromone. Since then, various other organisms have been studied and more is understood about the effects of pheromone, but not much is known about how pheromones work in more complex vertebrates such as humans...Until NOW!

Recently, an 8-week double blind placebo study was done on pheromones. Using 40 men, none of them knowing what was being tested. I.E use this toothpaste, use this coffee, use this perfume etc. The men who had used the perfume with the actual pheromones reported under baseline questioning that there was more sexual contact with there wife's and girlfriends. Single men reported more dates, romantic affection, eye contact and sex with women.

Researchers have proven male human pheromones trigger a SUBCONSCIOUS biological sexual response in women. Women are not conscious of the smell of the pheromones, but subconsciously, pheromones communicate sexual attraction. Pheromones are secreted by the perspiration glands when we sweat and, as you know, smell unpleasant. The Vemeronasal Organ (VNO) in our noses is the distinct sensory apparatus that detects pheromones.

Scientific research and studies done on Androstenone and the more concentrated form of Androstenone: Ospmopherone are very extensive and having been going on for over 20 years.

Researchers at the University of Kentucky discovered women exposed to pictures of men that were sprayed with male human pheromones found these pictures of those men more sexually attractive then pictures of men that were not sprayed with pheromones.These scientist's concluded that pheromones may explain why people often decide as soon as they meet some one that they like or dislike the person.

Scientific experiments have suggested that women exposed to men wearing this pheromone without being able to explain it were more attracted to these men then to men who were not wearing the pheromone.

Researchers have shown in clinical experiments male human pheromones trigger a subconscious sexual response in women. In one study, pheromone was sprayed on one chair in a dentist's waiting room. The other chairs were not sprayed. It was found women were more likely to sit in the chair sprayed with the pheromone then the others.

A similar study was done with three attached pay telephone booths. Only one of these three phones were sprayed with the pheromone and more woman used the sprayed phone than the other two.

In another reported experiment, twin brothers were used in the testing. Only one of the twins were sprayed with the actual pheromones. Women found the one twin brother who had the actual pheromone on more sexually attractive than the other. Now, remember these were twins both looking exactly the same, but the one wearing pheromones was found more attractive hands down. This experiment was done on a national TV show in England.

Pheromones imitate the properties of a substance secreted by men's armpits, which animal behaviourists have long felt is important in attracting mates at a subconscious level. To test the theory, 38 volunteers, aged 25 to 42, were recruited by researchers from the Department of Health and Nutrition Sciences, Brooklyn College, New York, and the Department of Psychology, San Francisco State University. After tests for adequate social skills, and a two week run-up period in which the men recorded their sexual activities, 17 unknowingly had the synthetic pheromone mixed in with their aftershave.

During the course of the trial, they experienced significantly more sexual episodes than men who did not have the extra ingredient. They were also more likely to engage in petting and kissing, or to have informal dates.

A total of 41% of men in the pheromone group experienced wide increases in sexual behavior involving a female partner, compared with 9.5% in the other group. Six out of seven men who had not been dating before the study showed significant increases in sexual behavior.

The results were published in the peer reviewed journal Archives of Sexual Behavior and were presented at a meeting of the American Society from Reproductive Medicine in Seattle. In the paper the authors write:
"Human male pheromones caused a statistically significant and distinct increase in the two most intimate behaviors: sexual intercourse and sleeping with a women. These are Social-sexual behaviors in which the willingness of a female partner plays a major role"
