The concept of man refers in the first instance to every human being of the male sex, every man has the sexual and social characteristics that differentiate him from the human being of the female sex known as Woman. The word Man is applied in two ways, one, as we have already explained, where the male race is denoted by individual, and we also refer to man when in an anthropological study we wish to generalize the entire human race, Example: “Man is the predominant race on earth ”.
The concept of Man focuses more than anything at present to separate the human being, classify it and give it characteristics, principles, foundations and utilities that differentiate it from women. The Man is the other part of the equation of a couple that forms a company called " Marriage " in which the man commits himself with a woman to consolidate a structure that guarantees the well-being for a family that was created from obtaining resources.
In the Biological branch of the natural sciences, man is one who has his XY chromosomes fixed, which will allow him to develop and have the male reproductive system (Penis, Testicles, Vas deferens and prostate) elements that are sufficient to produce sperm that later inserted in an ovule it will give continuity to life on earth. Another characteristic of man is the greater production of testosterone, a hormone that allows man to develop physically faster and easier. Men differ from women basically because of that, testosterone causes radical changes in men such as: thick voice, more toned and firmer muscles, hair growth on the face and thicker skin.
