Chest hair is related to race. Generally speaking, most white people have chest hair, while most Asian people do not. A small number of Asian men have chest hair, which begins to grow during puberty around the age of 14 or 15.

What's the relationship between chest hair and sexual ability?

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 for males and ovaries for females). Testosterone is the most important and abundant sex hormone in men's blood. During the embryonic period, testosterone determines the differentiation of sexual organs; during puberty, testosterone makes the individual further develop towards male sexual characteristics and plays an important metabolic function throughout life. For women, it is estrogen that causes gender differences.

Although estrogen and testosterone have important effects on the development of sexual characteristics, their effects on various organs of the body are different. Take chest hair for example. The sensitivity of hair follicles to androgens determines the growth of body hair. Some people's hair follicles are very sensitive. Even if the androgen concentration is low, their armpit hair and pubic hair below the pubic bone will grow a lot. Some people's chest hair follicles are not sensitive to androgens, so they will have less chest hair or even no chest hair. For example, some women have smaller breasts, which is affected by factors such as race, genetics and physique. For example, Western women have fuller breasts than Eastern women; if the mother has small breasts, the daughter's breasts will not be too full.
