Pheromones


Do you often wonder what makes someone attracted to you or what makes


you attracted to that other person? Sometimes you can look at the person and


not even be attracted to their looks, but you feel compelled to talk to them or


just contact them in any form. These urges could be induced by a compound group


most commonly called “Pheromones.”


Pheromones{fair’-uh-mohn} (from the Greek pher, “to carry” and horman


“to stimulate”) are chemicals released by organisms into the environment, where


they serve as signals or messages to alter behavior in other organisms of the


same species. Pheromones are a class of compounds that insects and animals


produce to attract members of their own species. These compounds are secreted by


the body in very small amounts but are never-the-less effective in producing


instinctive behavior when detected by the nose. In insects and animals, most


sexual and social behavior is controlled by pheromones.


Humans have used perfumes for thousands of years, but there is a basic


difference between perfume and pheromones. Pheromones are produced by the body


and usually do not smell at all pleasant, whereas perfumes are either


synthesized or extracted from natural products and are employed because of their


pleasant smell.


Scientific research suggests that there are human pheromones for both


the male and the female. Females have a better developed sense of smell and


testing indicates that they are more responsive to male pheromones than

the


reverse.


Research over the years has found that the male pheromones belong to a


class of compounds called steroids, in particular derivatives of androstenone,


which are secreted by perspiration glands on our bodies.


The compound androstenone, and a related product androstenol, are the


most commonly used compounds for testing the effects of pheromones on humans.


The tests usually involve getting subjects to select preferred objects from a


group of objects some of which have been sprayed with pheromones. For example;


statistics are taken of the use of the chairs in a dental waiting room when one


of the chairs has been sprayed with pheromones. It is reported that females


favor the chair marked with a male pheromones whereas males tend to avoid the


chair. Usually the subjects report that they are not conscious of the smell of


the pheromones, the preference shown appears to be a subtle unconscious action


in most cases.


To the perfume industry, the pheromone compound frequently contains


androstenone dissolved in a solvent. Also included is a masculine-like cologne


that is attractive to women. Upon application the solvent will evaporate leaving


the residual perfume and the androstenone. The small amount of perfume is


designed to attract women consciously while the androstenone-pheromone works in


the background in the unconscious way of most pheromones. Next time you are


strangely attracted to a person of the opposite sex, you could think whether or


not they are consciously using a pheromone.
