B-BOYS AND B-GIRLS ACROSS THE GLOBE! AND I QUOTE :)
THE SMELLS OF THE HUMAN BODY :)
The most sought after pheromones is the “primary pheromone“ that it supposed to render who wears it irresistible to potential partner. A pheromone found in the Rhesus monkey, "Copulin" has been researched in human vaginal secretions and has been experimented on males but without conclusive results.
The sweat glands are spread on the entire human body and produce three types of secretions, the apocrine glands are responsible for the production of smell. The development of the apocrine glands is a sexual characteristic and happens at the age of puberty, producing "adults" smells. The apocrine glands are present in quantity around to the nipples, on the genitals, under the armpits and on the hair skin.
They produce secretions under the effect of emotions, stress or sexual excitation. But many of body human smells are produced by bacterias and other microorganisms, who are working transforming little odorous secretions, like those apocrine or sebacee.
The characteristic smells of different parts of the body are the fruit of the interaction between these secretions and the microorganisms that live there.
The axillary secretions are the most studied by researchers because they are the exclusive patrimony of primates and of human beings, but also because those of males and of females are different and lastly because they are perceptible at a distance.
The ensemble of the sebacee glands, the eccrine and apocrine glands with the axillary hairs and the microorganisms living in the zone constitute "the axillary odorous organ".
Axillary depilation reduces drastically the capacity of the organ to produce its typical smell.
In fact the apocrine secretions are little odorous when they are produced, because the fatty acids, the proteins and the steroids that constitute them are complex and heavy molecules, therefore with little volatility.
It is the incubation with the bacterias of the skin that "digest" them “cutting” them that render them volatile, and odorous.
The main activity of the bacteria is to split acids from proteins to which they are bound at the moment of their production.
The axillary hairs multiply the living surface of the bacteria and multiply also the surface of evaporation of the smell.
The nature of the bacterial flora present on the armpits depends from the androgens levels of the persons, and this conditions also the smell produced from secretions.
The axillary secretions contain androstenol (also found in the urine) and androsterone (the scent of truffle), but also a great amount of aliphatic acids, other odorous steroids and compounds that are the "olfactory signature" of every person. There are also the smells from ingested foods and others caused by metabolic disorders (diseases).
The feminine secretions contain 50 times less androsterone than the male ones. Men and women produce for the greater part the same odorous molecules but their proportions change. For aliphatic acids, for example, they are opposite.
The axillary flora as well is very different: for example men have a much higher proportion of coynebacterium.
It is indeed the extreme complexity of the system of odorous production that allows for each person his individual smell, and this is corresponded by an equally sophisticated possibility of perception by our olfactory organ.
But this is what renders traditional search in this field nearly impossible, because besides all the individual physical factors that condition the chemical-odorous production of humans (age, diet, health, cycle, sexual activity, etc), the psychological aspect, specific to the human being, affects in determining way this production, and for the investigators it is practically impossible to find subjects who are in the same psycho-physical conditions in order to be able to draw incontrovertible conclusions.
Research in the olfactory field therefore would have to assume the methods of the pure physics research rather than those of the traditional medical research, in order to be able to progress beyond the nearly total ignorance in which we are today in regard.
