Do you think hairy men are more androgynous? Yes! It seems like sexual power is also stronger. Eh~~Really? In the end, it is not, to see to know ah! Men with a lot of body hair, giving people a feeling of extreme toughness. Compared to the fine flesh of the white-faced students, with this feature of the man for many women favored. The reason for this is twofold: one is because men have more body hair, natural form tough, can bring women more sense of security; one is because rumors that men have more body hair, sexual ability is strong, strong libido. The fact is really so, or some men and women wishful thinking? Body hair is mainly affected by androgens. The closest relationship with male physiological function is the testicles, because the testicles can produce androgens. The male testes produce androgens, which determine male physiological functions throughout life, from gender differentiation during embryonic life to secondary sexual characteristics changes during puberty, from maintenance of sexual function to fertility, and everywhere else. In addition, we need to note that hair at different body locations in men is not consistent with androgen levels. The most typical example is our hair. Men with high androgens are significantly more likely to lose their hair than those with low hormone levels. As a result, researchers have invented anti-androgen drugs to treat male hair loss. This is related to the expression of androgen receptors in different parts of the body, and scientists are still working on the mechanisms involved. It just goes to show how amazing the human body is. Androgens are the biological basis of male libido and sexual function, and can indeed be reflected to some extent by physical characteristics. We commonly see hypogonadism in patients with abnormal body surface. For example, some young patients, past puberty have not grown a beard, or only need to shave once a week, the voice is still a clear child’s voice, body hair is also very little; but in contrast, their fathers, male relatives and friends in the family, body hair are normal. There are also some men who have passed puberty and have not developed their genitals or grown pubic hair. These symptoms often suggest that we may have hypogonadism and need to go to the hospital. From a physiological point of view, secondary sexual characteristics can reflect, on some levels, a certain level of sexual strength in men. Body hair is mainly influenced by androgens, i.e. high androgen levels and relatively more body hair. However, we cannot ignore the role of genetics. For example, many European and American men have more body hair, obviously than yellow men, but their sexual ability is not necessarily stronger.
