Pheromones, those mysterious, scentless chemicals that some say drive human sexual behavior, have been studied for decades. But now researchers say they’ve finally found proof that mammals — such as humans and mice — are actually programmed to detect and use them.
A new study found exposure to male pheromones can boost a woman’s mood and stimulate the release of a hormone that regulates the menstrual cycle.
In the study, researchers applied extracts of underarm secretions from male volunteers to the upper lips of 18 women between the ages of 25 and 45. None of the women knew that male sweat had been applied to their lips, and some thought they were involved in a study of alcohol or perfume or even lemon floor wax. The women then rated their moods over six hours of exposure; they consistently reported feeling less tension and more relaxed.
“Much to our surprise, the women reported feeling less tense and more relaxed during exposure to the male extract,” says researcher Charles J. Wysocki of the University of Pennsylvania, in a news release. “This suggests that there may be much more going on in social settings like singles bars than meets the eye.”
Each of the women received three applications of the underarm extract during the six-hour evaluation period, followed by three doses of exposure to ethanol (alcohol) over another six-hour period.
Researchers also found that exposure to the male pheromones also prompted a shift in blood levels of a reproductive hormone called luteinizing hormone. Levels of this hormone typically surge before ovulation, but women also experience small surges during other times in the menstrual cycle.
In another study, The Australian organization, Bennett Research, conducted a survey of 306 men using pheromones. Ninety percent of them claimed that it had increased their attractiveness to women. Increased response from women was measured by:
A significant measure was a big increase in physical response by women
- Brushing against the pheromone wearers (31%)
- Touching them (30%)
- Becoming sexually excited (18%)
- Expressing a desire for sex (17%)
- Actually having sex with them (16%).
Human pheromones are highly individualized, and not always noticeable. In 1986 Dr. Winifred Cutler, a biologist and behavioral endocrinologist, co-discovered pheromones in our underarms. She and her team of researchers found that once any overbearing underarm sweat was removed, what remained were the odorless materials containing the pheromones.
In a double blind experiment with young women 36 percent of those exposed to pheromones had sex weekly during the first three weeks of the study. Of those receiving a placebo only 11 percent had weekly sex. By the end of the study, 14 weeks, 73 percent of the pheromone users were having sex every week, while those on the placebo stayed at 11 percent.
By far the best way to produce and release human sex pheromones is to take the synthetic route. If you want to be able to attract women regularly, effectively and consistently… there is no way you are going to be successful by relying on the release of natural pheromones alone. You need to increase the amount and potency of the pheromones that your body naturally releases. There are many products out there that have been proven to increase the release of pheromones and there effectiveness.
In humans, pheromones are activated at puberty. Both men and women produce varying amounts of “male” pheromones: androstenone and androstenol, only women secrete the “female” pheromone copulins. Produced by the apocrine glands in the armpit and around the genitals pheromones send signals that are picked up by the vemeronasal organ (VNO), just inside the nose. The VNO passes these messages on to the limbic part of the brain which governs the most basic human sensations, like joy, anger, love, hate and sexual arousal.
Synthetic products such as pheromone pills and pheromone sprays are now regarded as the very best way to increase the amount and potency of the pheromones that you release.
Dr. Cutlers 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.
Peter Karlson and Martin Lüscher first proposed the word “pheromone” in 1959, referring to a chemical cocktail emitted by an animal and detected and responded to by other creatures of the same species. That same year, researchers reported the identification of the first pheromone (called bombykol) in silk moths.
In animals, sex pheromones indicate the availability of the female for breeding. Male animals may also emit pheromones that convey information about their species and genotype.
At the microscopic level, male copepods can follow a three-dimensional pheromone trail left by a swimming female, and male gametes of many animals use a pheromone to help find a female gamete, for fertilization.
Many insect species release sex pheromones to attract a mate, and many lepidopterans (moths and butterflies) can detect a potential mate from as far away as 10 kilometers (6.25 mi). Traps containing pheromones are used by farmers to detect and monitor insect populations in orchards.
Pheromones are also used in the detection of oestrus in sows. Boar pheromones are sprayed into the sty, and those sows that exhibit sexual arousal are known to be currently available for breeding. Sea urchins release pheromones into the surrounding water, sending a chemical message that triggers other urchins in the colony to eject their sex cells simultaneously.
Pheromone products usually contain these 4 pheromones:
Androstenone (a.k.a A-none)
Androstenone pheromone is found in both men and women, is predominantly known of as a male pheromone. It typically creates a dominant, intimidating, aggressive aura. Alpha aggressiveness is often associated with good mate choice.
Androstenol (A-nol): signals sociability. It often seems to cause conversation, it can be a good ice breaker.
Androsterone (A-rone): Signals masculinity. This pheromone creates an aura of protection and reliability normally associated with a peaceful alpha male. Androsterone provides the respect of androsteNone but without the possible negative connotations of the aggressive nature of androsteNone. When worn by women, androsterone can have mood elevating effects.
Androstadienone (A1): is also called the “love pheromone” because of the nature of the feelings and reactions it induces in women.
