Strong Bodybuilding Man Portrait

The term manhood is used to describe the period in a human male's life after he has transitioned from boyhood, having passed through puberty, usually having attained male secondary sexual characteristics, and symbolises a male's coming of age. The word man is used to mean any adult male. In English-speaking countries, many other words can also be used to mean an adult male such as guy, dude, buddy, bloke, fellow, chap and sometimes boy or lad. The term manhood is associated with masculinity and virility, which refer to male qualities and male gender roles.
Biology and gender
Humans exhibit sexual dimorphism in many characteristics, many of which have no direct link to reproductive ability, although most of these characteristics do have a role in sexual attraction. Most expressions of sexual dimorphism in humans are found in height, weight, and body structure, though there are always examples that do not follow the overall pattern. For example, men tend to be taller than women, but there are many people of both sexes who are in the mid-height range for the species.
