When human pheromones hit the news, they made a big splash in the media. Articles about pheromones appeared in major newspapers and magazines, and they were discussed on radio and TV talk shows. Advertisements and infomercials for products containing pheromones were quick to follow, as well as numerous offerings on the Internet.

Pheromone Research in Humans

As a result, you can supplement your own pheromones with spray-on, rub-on, or splash-on versions that will work sexual magic – if the products live up to their extravagant advertising claims. For example:

Pheromones attract, compel, make you irresistible…Others will be drawn to you without knowing why.. .Pheromones give you the secret advantage over other men (women). Your knowledge of pheromones will help you evaluate such claims. If you do decide to try a pheromone product, you will be doing it with your eyes open. Keep in mind, though, that there is such a thing as a placebo effect. You often get what you expect.

Regular exposure to male pheromones helps normalize the menstrual cycle. It makes it shorter and more regular. Each month, a woman’s susceptibility to male pheromones peaks at the time of ovulation, when she is most fertile. Exposure to male pheromones in musk can cause women to ovulate more readily and become more easily aroused. Regular exposure to male pheromones accelerates the beginning of puberty for girls.

Pheromone Effects on Men

Among animals, the whiff of male pheromones – especially androstenone – makes other males aggressive. In humans,  androstenone is a strong presence in male sweat. Could this help explain aggressive behavior of males who congregate – and sweat – together? James Vaughn Kohl and Robert T. Francoeur, authors of The Scent of Eros, note that there is speculation about this connection between male aggression and the smell of male sweat.

They cite as examples hostile graffiti in men’s restrooms, aggressive behavior of men in large groups and on the hockey rink, basketball court, or football field. Researchers at Birmingham University sprayed a chair in an office waiting room with a mist containing the male pheromone androstenone, which has a urine-like smell.

Men avoided sitting in the chair, especially when androstenone was applied in heavier doses. (Women were attracted to the chair.) Exposure to androstenone may stir erotic memories or sexual desire.

Female Pheromone Effects on Men

Regular contact with women reportedly makes the beard grow more rapidly. The presence of female pheromones can stimulate production of male hormones. This, in turn, stimulates beard growth. There is anecdotal evidence from sexual folklore that the sweat and vaginal secretions of a woman are aphrodisiacs, but this has not been scientifically proven.(Both sweat and vaginal secretions contain female pheromones.)

Pheromone Effects on Women

When women live with other women they tend to have their menstrual period at about the same time. This synchronization is caused by “messages” from female pheromones transmitted in sweat. Often their menstrual cycles become synchronized with that of the dominant woman in the group.

Long-term exposure to female pheromones may increase sexual desire among women. In one double blind  study,  young women were exposed either to female pheromones  or to a placebo. After  fourteen weeks, the percentage of women having sex on a weekly basis increased from 11 percent to 73 percent for women receiving the pheromones. It remained the same for those who received the placebo

Pheromone Secretion in Humans

Together the skin, glands, bacteria, and hair create a working pheromone factory. What happens when a woman shaves her underarms and legs? Theoretically, what she gains in aesthetics she may lose in pheromones, at least temporarily. Underarm hair helps trap body secretions and increases skin warmth for pheromone evaporation.

No Sweat?

When Napoleon asked Josephine not to bathe for three days, he was not alone in his aromatic preferences. The “sweat is sensual” school continues to have its advocates, despite the best efforts of all those who seek to deodorize us as a species. Considering what we know about pheromones, maybe we should throw out our deodorants, aftershaves, perfumes, and colognes and instead just work up a good sweat.

It is not unusual to love the sweaty scent of a lover, because that sweat carries the lover’s smellprint. It is unique, and immediately recalls the lover’s physical presence in a way that even a photograph cannot. That is why a woman may wear her lover’s T-shirt, and why people find themselves sleeping on the other side of the bed when their lover is gone.

The lingering smellprint is a comforting reminder of the lover’s physical presence.

No Smell?

Suppose the issue is not “to smell or not to smell,” but that you can’t smell – either temporarily, because of a cold, or permanently (a condition called anosmia). The good news is that although you  cannot  smell   odors,  you can still perceive pheromones through your VNO.

Don’t Fight Your Pheromones

If the “chemistry isn’t right” in a romance, consider that your pheromones might be trying to tell you something. Perhaps your partner’s immune system is too similar to yours. Based on animal studies, it appears that we unconsciously “read” a prospective lover’s pheromones to help us find a mate with a compatible immunotype (someone whose genes carry immunities we do not have). Given a choice of mates, rats use smell to find a mate with a different immunotype. In fact, they choose    the one who   is most different. Opposites attract. It is nature’s way of distributing genes – and immunities – throughout a species.
