Man (adult human male)
An overview of the term 'man' as an adult male human, covering biology, development, social roles, terminology, historical context, and related movements and distinctions.
A man is typically defined as an adult male human. The word is used in biological, legal and social contexts to indicate a person who has reached adulthood and who is classified or identifies as male. In English the singular is "man" and the plural is "men"; related terms such as "boy" and "woman" distinguish age and sex or gender in common usage.

Biology and development
Biologically, most men develop male reproductive anatomy and secondary sex characteristics during puberty, a process driven by hormones. Typical human male chromosomal patterns involve one X chromosome and one Y chromosome, but sex development can vary and not all people fit simple categories; intersex conditions and medical diversity are important considerations. Adulthood is commonly marked by physical maturity, legal age thresholds, and social recognition.
Social identity and roles
The classification "man" carries social and cultural meanings in addition to biological ones. Expectations about behavior, work, family roles and appearance—often called masculinity—differ widely between societies and historical periods. Many cultures have rites of passage or legal markers that recognize the transition from boyhood to manhood. Gender identity is the inner sense of being male, female, both or neither; a person who identifies as male is generally described as a man whether or not they were assigned male at birth.
Terminology and distinctions
Common distinctions relate to age, sex and gender. "Boy" usually denotes a male child or adolescent, while "man" denotes an adult. "Male" can refer to biological sex, and "masculine" to traits culturally associated with men. The term "transgender man" refers to someone who was assigned female at birth but who identifies and often lives as a man. Language and legal frameworks differ about how and when someone is recognized as a man in various contexts.
History, movements and notable facts
The social roles of men have changed over time with shifts in economy, politics and cultural values. Movements that address issues affecting men include advocacy for paternal rights, health awareness, and political activism such as the men's rights movement; others focus on challenging harmful norms and supporting gender equality. Discussions about men's roles intersect with debates about sexism, stereotypes and efforts to reduce gender-based violence.
Contexts of use
- Legal: laws often define adulthood and rights for men and women separately in some systems.
- Medical: medical care may address male-specific health issues and variations in sex development.
- Cultural: literature, religion and customs influence expectations of men.
- Linguistic: many languages have distinct words and grammatical forms for males and females.

This article aims to present a concise, neutral account of what is commonly meant by "man" across biological and social domains. Terminology and recognition differ across cultures, legal systems and individual experiences; where precise definitions matter, consult specific legal, medical or cultural sources.
Etymology
The gemeingerm. word mhd., ahd. man goes back to idg. manu- or monu- "man, man". What conception underlies this naming of man cannot be clarified with certainty.
Biological and medical characteristics
→ Main article: Human sex differences
Genetic characteristics
From a molecular biological point of view, man differs from woman by the chromosome pair XY (but see also XX-man) in the sex chromosomes (instead of XX in woman, but see also XY-woman). This difference leads to a sexual dimorphism. Due to the coincidence of an X chromosome from the maternal side (ovum) and a Y chromosome from the paternal side (sperm) in the zygote, this dimorphism arises in relation to the formation of the sex organs already during embryonic development. Males therefore usually have one X chromosome and one Y chromosome in their chromosome set. The latter contains a region called the sex determining region of Y (SRY), which in males is responsible for the embryonic production of the testis determining factor (TDF), a protein. If TDF is produced, male characteristics are formed; if it is missing, female characteristics are formed.
Morphological and physiological characteristics
Men differ physically from women by the different primary and secondary sexual characteristics. The construction of the primary sexual characteristics is mainly due to their function in reproduction. These are mainly
- the presence of male gonads, the testes, in which the male gametes, the sperm, are produced.
- the development of the primary sexual characteristics penis and scrotum in the human embryo.
- the development of secondary sexual characteristics during puberty, such as beard growth, a deeper voice than the female, broader shoulders, a narrower pelvis, a lower body fat and higher percentage of muscle in the total weight, a higher growth as well as generally stronger body hair, all of which are the result of a higher level of the male sex hormone testosterone in the blood.
For missing sex characteristics and multisexuality, see intersexuality and transgender.
Skeleton
Female and male pelvises differ. The hip bone hole in females has an oval shape, and the pelvic scoops are wider. The male pelvis, on the other hand, tends to be high, narrow and tight. The most important feature to distinguish is the angle of the pubic symphysis. It is greater than 90° in the female pelvis and less than 90° in the male.
Likewise, the skull shapes differ. Only male skulls have a clearly pronounced bulge above the eyes.
The finger proportions of men and women are different. For most men, the ring finger is longer than their index finger. In women, on the other hand, the index finger is longer than the ring finger, or at least the same length. A common hypothesis sees the cause for the different finger length ratio in the testosterone level in the womb.
Men's skin
The appearance of male skin (oilier and with larger pores than female skin) is mainly influenced by hormonal skin differences, e.g. skin thickness and increased sebaceous gland secretion.
The thicker male skin has a higher water-binding capacity, which makes the skin look tighter and firmer. The increased sebum production is responsible for a sufficient amount of moisture in the skin and for the composition of the so-called hydrolipid film. This film regulates the water content of the deeper layers, inhibits dehydration and gives the skin a smooth, supple appearance.
In addition, men's skin has a lower tendency to wrinkle. Wrinkles usually appear later in men than in women and also not as small creases, but more as deep ("prominent") wrinkles.
As a result of increased sebum production, blackheads and acne can occur more often, especially in young men. These occur when the sebum, together with dead skin cells, clings to the pores. An irritation of the blackheads leads to the settlement of germs and inflammatory pimples.
Andrology
The branch of medicine that deals with male diseases is called andrology. In general, men can be affected by the same diseases as women, but some gender-specific diseases also exist; for some other diseases, women and men show significantly different disease distributions (for example, for red-green vision impairment and other X-linked hereditary diseases).
