The role of pheromones in sexual attraction 

Most of us have heard many times talk about pheromones but sure, we all wonder what they are exactly and if it is true that relationship, which has always been spoken between pheromones and sexual attraction.

Well, yes, pheromones exist and are a substance secreted by living beings whose purpose is to cause a series of particular behaviours in other individuals of the same species. We could say, therefore, that pheromones are another form of communication between individuals. Its importance at the time to cause a physical attraction between different individuals is a fact.

But How do you detect the human pheromones? Through an auxiliary organ of the sense of smell that is situated between the bone of the nose and the mouth. This explains the effectiveness and the growing market of all products that contain pheromones among which are perfumes, and, to a lesser extent, the moisturizing creams whose composition is based on the miraculous substance.

Men and women respond differently to the smell of two substances that could be involved in sexual attraction.

The brain of heterosexuals and homosexuals also responds differently to the odor of pheromones. But, in homosexual men, the brain response is similar to that which occurs in heterosexual women. 11 In this sense, the homosexual, the response hypothalamic to the male pheromone would be determined by the sexual orientation, and not by biological sex. 

This finding may open the way to studying human pheromones, as well as the biological basis of sexual preference.
What are pheromones?

Pheromones are chemical substances secreted by some animals that, when they are olfateadas, cause specific reactions in other animals of the same species, especially in what refers to the sexual attraction prior to mating.

Experts differ as to the role that can play the pheromones in sexual attraction between human beings. 

Two chemicals are currently candidates to be recognized as human pheromones: a derivative of testosterone, known with the acronym AND, and a substance similar to the female estrogen, which is marked with the initials EST.

How do they work?

The pheromone AND is detected primarily in the sweat of male, and the pheromone is in the urine of women.

The two alleged human pheromones activate brain by a route and in a location other than as they do other odorous substances.
In the female, the pheromone ESTS (female) activates the brain region associated with the smells ordinary.
In contrast, in man, activates the hypothalamus, a brain region that controls sexual behavior through the pituitary gland or hypophysis, which is the one that governs, in the manner of a conductor, the hormonal balance of the body.

The pheromone AND (male), detected in the sweat, a male, has the opposite effect: it activates the hypothalamus in women, and in men, the brain region associated with the smells ordinary.

The two smells, pheromones EST (estrogen) and AND (andrógenica) seem to play a double game: they play the role of an ordinary smell in a sex and of pheromone (which causes sexual attraction) on the other.
