"Male laryngeal nodules, chest hair, and female breasts are all referred to as secondary sexual signs, which are manifestations of physiological differences between the sexes. However, whether chest hair is related to sexual ability needs further confirmation.".
The difference in secondary sexual characteristics between men and women is mainly related to the hormones secreted by the body. Testosterone is the most important and abundant sexual hormone in men's blood. During the embryonic stage, testosterone determines the differentiation of sexual organs; During puberty, testosterone further promotes the development of individuals towards male sexuality and plays an important metabolic function throughout their lifetime.
This also indicates that estrogen and androgen have an important impact on the development of sexual characteristics, such as chest hair. The growth of body hair has a certain relationship with the amount and sensitivity of male hormones. Some people have very high levels of male hormones, but because of their low sensitivity to male hormones, they do not have excessive chest hair. On the contrary, there is an abnormal amount of chest hair with less male hormones.
Therefore, the second sexual characteristic of a person cannot be used as a measure of sexual ability.
However, from other aspects, chest hair has a certain deepening effect on men's charm. Women all like "masculine" men, and the expression of masculinity is related to more hair, a large Adam's apple, and a rough voice. They believe that men with hairy chests are more masculine, and their sexual function will also improve.
Therefore, to judge the strength of a man's sexual function, it is not necessary to obtain information from his appearance, but rather to judge it by getting along with each other. If a man discovers that he has sexual problems, he should seek medical attention in a timely manner.
