What causes anal hair in men?

The male body is very different from the female body. First, the physiological structure is different, and second, the appearance is different. The difference in physiological structure is the most important difference, but both men and women have excretion openings such as the anus and urethra. However, the gender characteristics of the male anus and urethra are more obvious, and some men even grow a lot of hair in the anus. So, why do men grow anal hair?

Anal hair refers to the body hair around the anus, which exists in both men and women. Adult men's anal hair is usually denser than that of adult women. Anal hair is connected to pubic hair and thigh hair. Many people believe that anal hair is actually part of pubic hair.

During the growth and development period, in addition to the obvious functions of the body, male secondary sexual characteristics such as pubic hair are also obvious. Pubic hair grows widely and is mostly triangular. Some people also grow pubic hair in the anus. This is a normal physiological phenomenon and there is no need to worry. It is recommended to maintain good hygiene and wash it after bathing or defecation.

Causes of growth:

The growth of hair around the anus is a physiological phenomenon, so don't worry. In fact, humans evolved from apes, and apes have hair all over their bodies, including around the anus. With evolution, human hair has become increasingly scarce, but the area around the anus has not evolved yet, that's all. The growth of hair on certain parts of the human body is mostly genetic, and it is also related to the local climate. Generally speaking, people in hot places have less or thinner hair, and the opposite is true in cold places, but this is not absolute. In addition, the growth of pubic hair has a lot to do with human secretion. If more hormones are secreted, the human body will naturally grow hair. Generally speaking, adults have hair, it's just a matter of how much. With evolution, human body hair has become increasingly scarce, and anal hair, like wisdom teeth and appendix, is a trace organ of humans.

effect:

Anal hair can keep the anus ventilated and can also exclude bacteria that are about to invade the anus to prevent bacterial infection. However, too dense anal hair may allow fecal bacteria to attach to the anal hair.
