Man
Overview
A man (男子) refers to a human being who is biologically of the male sex, or a person who is socially and culturally defined as male or who identifies himself as male. On the biological level, XY chromosomes, a testosterone-centered hormonal system, male reproductive organs, and secondary sex characteristics are cited as key features. However, because the content of "manliness" varies greatly by era, culture, and class, modern academia bases its approach on distinguishing biological sex (sex) from social gender (gender).

Biological Characteristics
Human sex determination is generally accomplished by the combination of X and Y chromosomes, and in the case of an XY combination, testes develop and androgens such as testosterone are secreted. During puberty, secondary sex characteristics appear, including voice change, development of facial and body hair, increased bone and muscle mass, and growth of the larynx. However, chromosomes, hormones, and anatomical sex do not always align, and it has been medically confirmed that a spectrum of sex development exists, such as in Klinefelter syndrome or androgen insensitivity syndrome.
Sociocultural Masculinity
Masculinity is the totality of behaviors, attitudes, and roles that a particular society expects of men. Traditionally, toughness, initiative, the role of economic provider, and emotional suppression have been emphasized, but its content is rapidly being reorganized with industrialization, women's advancement into society, and changes in family structure. Recently, the concept of "toxic masculinity" has emerged, pointing out that the suppression of emotional expression and violent norms are harmful to men themselves as well.
Historical Changes
In ancient societies, male roles as warriors, hunters, and heads of households were prominent, and in modern industrial societies, the identity of wage worker and family provider was reinforced. Since the late 20th century, with the development of the women's movement and gender studies, the division of sex roles has weakened, and trends recognizing men who participate in childcare and housework and diverse gender identities have spread.
Health and Medicine
Men's average life expectancy tends to be shorter than women's, and cardiovascular disease, liver disease, smoking- and alcohol-related diseases, and prostate disease are cited as major health issues. In addition, because of the social norm that "men endure when sick," the rate of healthcare service use is low, and problems of high depression and suicide rates are reported in many countries. Recently, male hormone testing, prostate-specific antigen (PSA) screening, and expanding access to mental health counseling have emerged as major tasks.
Psychological Aspects
Numerous studies indicate that men are likely to experience social suppression in emotional expression and seeking help. Role conflict, achievement pressure, and the burden of the father role affect mental health, and the fields of men's counseling and masculinity studies that address these are growing.
Recent Trends
In 2024–2025, the discourse on masculinity is becoming more multilayered. First, centered on online communities and short-form platforms, "self-development masculinity" and "conservative masculinity" are spreading simultaneously, and the perception gap between generations is widening. Second, in corporate and policy areas, systems encouraging men's parental leave and participation in caregiving are expanding. Third, as interest in men's health rises, lifestyle industries such as mental health, hormonal health, and hair loss and skin care are growing. Fourth, research on the effects of artificial intelligence and digital environments on dating, relationship formation, and male images in media is becoming active. Finally, it is noteworthy that in Korea and various other societies, debates over low birth rates, military service, and gender equality policies are politically reconstructing the category of "man."
