Persons whose anatomy or chromosomal makeup differ from this pattern are referred to as intersex.

There are also transgender and transsexual men, who were assigned as female at birth, but identify as men; there are varying social, legal and individual definitions with regard to these issues.

(See trans man.) The male sex organs are part of the reproductive system, consisting of the penis, testicles, vas deferens, and the prostate gland.

For males during puberty, testosterone, along with gonadotropins released by the pituitary gland, stimulates spermatogenesis, along with the full sexual distinction of a human male from a human female, while women are acted upon by estrogens and progesterones to produce their sexual distinction from the human male.

Sometimes gender scholars will use the phrase "hegemonic masculinity" to distinguish the most dominant form of masculinity from other variants.

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. 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.

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.

In mankind, the sex of an individual is generally determined at the time of fertilization by the genetic material carried in the sperm cell.

The Old English form had a default meaning of "adult male" (which was the exclusive meaning of wer), though it could also signify a person of unspecified gender.
