Pheromones will be more commonly associated with animals and insects, that is a chemical factor which is either excreted or secreted to trigger a unique social response inside the members of exactly the same species. One such illustration of a particular social response is procreation, in which animals and insects usually leave a secretion or excretion of the chemical, normally urine, to signal the opposite sex for fertility.
However, besides animals and insects, humans are also believed to produce pheromones which may also trigger numerous special social responses for the receiver. This too includes attracting a potential partner for procreation, or more popularly known as "one-night stands".
Information on Human Pheromones
In accordance with many experts, human pheromones also exists, that many of us absentmindedly uses pheromones to interact with other humans. Just about the most popular studies done to prove a good human pheromones is that of Martha McClintock and her study of human pheromones affecting a woman's menstrual period.
In their study, she exposed several women to some whiff of perspiration using their company women. It had been found that it caused their menstrual cycles to speed up or decelerate depending on the amount of time in the month the sweat was collected: before, during, or after ovulation. Therefore, these studies proposed there are two kinds of pheromone involved: "One, produced prior to ovulation, shortens the ovarian cycle; and the second, produced just at ovulation, and lengthens the cycle".
However, apart from affecting a woman's menstrual cycles, human pheromones may also be used as aphrodisiac or as method for attracting the opposite sex for procreation, with either love or for "one-night stands". This is the time pheromone products were introduced as products to increase someone's attractiveness.
Pheromones for Love
Although there are no concrete evidence towards the effect of human pheromones for increasing a person's sexual desires, several studies have done which have produced a number of small proofs with the effect of human pheromones as aphrodisiac.
In accordance with these studies, men produce pheromones with this special social response through their arm pits, while women secrete this chemical through their scalp and right down to their head of hair. Such studies suggest that women can attract men having a whiff of these hair, while sweat from the man's armpit has been said attract women.
