Does a man with more chest hair mean he is more capable?

Men with more chest hair have stronger sexual abilities

Q: I heard from a friend that men with more chest hair have stronger sexual abilities. But I have almost no chest hair and my Adam's apple is not very obvious. Does this mean that my sexual ability is weak?

Beijing Reader Mr. Sun

A: 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.

Target Organs

Although estrogen and testosterone have important effects on the development of sexual characteristics, the effects of these hormones on various organs and skin of the body are different. Take chest hair for example. The sensitivity of the target organ, the hair follicle, to androgen 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 begin to grow. However, some people's chest hair follicles are not sensitive to androgen, so they will have less or 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.

In general, men and women should not use secondary sex characteristics as the primary criterion for measuring sexual ability.
