Pheromone is something which cannot be seen and helps bringing the differing sex together. The signs of chemicals released by one animal tend to affect the behavior of another associate of the same species. This is in different way for different gender. In animals male uses it to detect and mate the female, where as in the female it defines her willingness for mating. But do pheromones work is still not proved.
In human beings the emotions are largely driven by smell. With respect to other mammals they have dense and concentrates glands producing sweat. Human use organs known as vermonasal present in their nose to detect that smell which is present in the air. It is then that the stimuli reach the brain and responses pertaining to emotions are produced. This is how do pheromones work in humans.
Just like fingerprints each human being has odor print connected with the sweat glands and matures during adolescence. You can find them in the areas like armpits, pubic, eyelids and the other genital regions. Even after using so much perfumes or deodorants the effect of pheromones can never be reduced. Since the underarms are the warmest portion of our body it is the most ideal place for release of pheromones. They have large number of sweat glands and so many hairs which helps the odor to disperse properly. Since they are present in the upper part of the body it creates an effect on the other person nose as well.
A person can also use perfumes and other smells to bring changes in the natural pheromone generated by the body. This can also help him attract the opposite gender. Such pheromone products are available in market also. One should be aware of how do pheromones work depending upon the version.
