Is it okay to judge a man by his appearance?

There has been a popular saying that a man's sexual ability can be judged based on his appearance, such as his body shape, nose size, baldness, body hair, Adam's apple size, and even palm lines. Internet celebrity "Mu Zimei" once collected photos of male fans' hands on Weibo, and commented on their genital size and sexual ability one by one, which further fueled this saying. Can a man's sexual ability really be seen from his appearance?

Body shape

Muscle growth is inseparable from the role of male hormones. Males with well-developed muscles can basically indicate that their male hormones are normal. Male animals often show off their appearance to attract female animals. In fact, humans are similar. Men with well-developed muscles and strong physiques will also attract the attention of women. Women subconsciously believe that such men have strong reproductive ability and have advantages in passing on the family line. In addition, physical exercise can promote the secretion of male hormones, and sexual life requires a certain amount of physical strength. Muscular men who exercise frequently are likely to score high in sexual performance.

In contrast, men who are too thin or obese may not have such strong sexual abilities. Especially for fat people, medicine believes that fat accumulation is related to the increase of estrogen in the body. The increase of estrogen inhibits the production of androgen. Fat people are prone to problems such as high blood lipids and arteriosclerosis, which affect the blood supply capacity of blood vessels and of course the blood vessels of the penis. In addition, fat people lack exercise and endurance, which will also reduce their sexual ability. At this point, I can't help but think of the pot-bellied "12-second" official.

Adam's apple

Like the beard, Adam's apple is one of the secondary sexual characteristics of men. In addition to genetic factors, it can reflect the secretion of male hormones to a certain extent.

However, there is a type of men who are tall but thin, with long arms, inconspicuous Adam's apples, and almost no beards. In folk terms, they look a bit like eunuchs. They often go to the hospital for infertility. In fact, their genitals are also small, pubic hair is sparse or even absent, and sexual function is also poor. This type of man may suffer from "Klinefelter syndrome", also known as "congenital testicular dysgenesis". Their chromosomes have an extra "X" than ordinary men, and they often need to take drugs to help restore their male characteristics.

Hair

Some women hate bald men and regard them as a symbol of aging, while some women have a stronger taste and prefer bald men.

From the perspective of traditional Chinese medicine, the kidneys are responsible for reproduction and hair. Male baldness may be caused by kidney qi deficiency.

Western medicine doesn't think so. According to Western medicine theory, testosterone is the most important male hormone in the male body, mainly secreted by the testicles. Testosterone combines with an enzyme in the human body and is converted into dihydrotestosterone. In addition to maintaining a man's normal sexual desire, dihydrotestosterone can also stimulate muscle growth, promote body hair growth, and mature hair. Too much dihydrotestosterone will enter the hair follicles, causing the hair follicles to mature prematurely, resulting in a shortened hair growth cycle and premature hair loss. Hair loss means that his body has high levels of male hormones, or that his body is more sensitive to male hormones. Compared with normal people, their sexual desire is naturally stronger.

However, sexual desire and sexual ability are two different things. Sexual desire refers to whether one wants to do it, while sexual ability refers to whether one can do it. In general, baldness is not a sign of strong sexual ability, nor is it a sign of poor sexual ability.

Body hair

Men with "manliness" are particularly attractive to women. In terms of appearance, "manliness" is not only associated with well-developed muscles, but also with more body hair, a large Adam's apple, and a deep voice. In particular, men with sideburns and thick chest hair are more often considered to be masculine and have higher sexual function.

In fact, the amount of body hair is more closely related to genetic factors, but it is also a reflection of the level of male hormone secretion. As mentioned earlier, although androgen can also affect sexual function, the relationship is not proportional. Male sexual function requires the coordinated operation of multiple systems such as endocrine, nerves, muscles, and blood vessels. It cannot be judged by only male hormones.

Nose, palm

This is just a joke and has no scientific basis. It is said that men with big noses also have big genitals and extraordinary sexual abilities. It is also widely believed that judging sexual ability through palmistry is based on which the size of a man's genitals and sexual function are evaluated one by one.

In fact, there is no scientific basis for such claims. Take the nose for example. The shape of the nose is more related to race and genetics. If a high and straight nose means strong sexual ability, then aren't all white people full of energy? Then why is there "Viagra" on the market? Judging sexual ability by palmistry is just a joke.

Sexual ability is a reflection of a man's overall physical and mental health.

A man's sexual ability cannot be determined by the size of a certain part of his body, but is a reflection of his comprehensive physical and mental health, such as his congenital genetics, acquired endocrine system, nervous system, muscle tissue, vascular function, body metabolism, and nutritional status.

It is also related to educational background, sexual knowledge, sexual experience, etc. Men who are born with abundant body hair, well-developed muscles, and strong physique only have better capital in sexual function, but if the acquired conditions are not good, it is also useless.
