Do men with more chest hair have stronger sexual abilities?

People say 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?

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

Secondary sexual characteristics are mainly caused by the differences 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 sexual organs; during puberty, testosterone causes the individual to further develop towards male sexual characteristics and continues to play an important metabolic function throughout life. For women, it is estrogen that causes gender differences.

Although estrogen and androgen have important influences on the development of sexual characteristics, their effects on various organs of the body are different. Taking chest hair as an example, the sensitivity of hair follicles to androgens determines the growth of body hair. Some people's hair follicles are very sensitive, and their armpit hair and pubic hair below the pubic bone will grow a lot even if the androgen concentration is low. However, some people's chest hair follicles are not sensitive to androgens, so they have less 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.
