Why do men have chest hair?

Male Adam's apple and chest hair, female breasts and fat distribution are all called secondary sexual characteristics, which refer to the differences between the two sexes other than the genitals. They are manifestations of physiological differences between men and women, but they cannot be equated with sexual ability.

Secondary sexual characteristics are mainly caused by the difference in sex hormones secreted by male and female gonads (testicles in males and ovaries in females). Testosterone is the most important and abundant sex hormone in men's blood. During the embryonic period, testosterone determines the differentiation of sex organs; during puberty, testosterone makes the individual further develop towards male sexual characteristics and plays an important metabolic function throughout life. For women, estrogen is the most important sex hormone.

The amount of body hair is more closely related to genetic factors, but it is also a reflection of the level of androgen secretion. Although androgen can also affect sexual function, the relationship is not proportional.
