Why are the testicles wet?

Many male friends will find that their testicles are always wet if they pay attention. This situation will make many friends who don't understand confused about what is going on and think that there is something wrong with their body. In fact, this situation is a normal reaction and is good for the body. So why are the testicles wet? Let's learn more about it through the following introduction, hoping to help friends.

Studies have shown that male testicles are very afraid of high temperatures, and the scrotum is always wet. In fact, this is how the low temperature effect is achieved. The sperm, the "messenger" of male fertility, is produced by the two testicles growing in the scrotum, and the testicles produce sperm at a temperature that is very sensitive. When the body temperature is 37°C, the appropriate temperature for the testicles to produce sperm is 35°C; if the temperature is too high, the spermatogenesis function will be impaired or even completely stopped. Therefore, the scrotum achieves this "low temperature" through the following methods.

Therefore, keeping the private parts moist all year round can ensure the fertility of men. Scrotal moisture is an important part of ensuring male fertility. The sperm, the "messenger" of male fertility, is produced by the two testicles growing in the scrotum, and the production of sperm by the testicles is sensitive to temperature conditions. When the body temperature is 37°C, the suitable temperature for the production of sperm by the testicles is 35°C; if the temperature is too high, the sperm production function will be hindered or even completely stopped. Therefore, the scrotum achieves this "low temperature" through the following methods:

①The skin is very thin and has abundant sweat glands. If the surrounding environment or the internal temperature of the body rises slightly, the scrotal skin will sweat to dissipate heat;

② The skin has many wrinkles, which increases the surface area of ​​the skin, and thus increases the surface area for sweating and heat dissipation;

③The skin is rich in blood vessels, which can quickly remove excess heat from the scrotum;

④ There is a thin layer of muscle under the scrotal skin, which is very sensitive to temperature changes. When the temperature inside the scrotum rises, it relaxes, allowing the surface area of ​​the scrotal skin to expand and sweating to dissipate heat easily. On the contrary, when the temperature inside the scrotum drops, it shrinks, causing the surface area of ​​the scrotal skin to shrink and reducing sweating to dissipate heat;

⑤ The scrotum hangs down outside the body's internal organs. This position reduces the impact of the body's internal organs' temperature.

Through the above introduction, we know why the testicles are wet. Generally speaking, it is a normal physiological reaction, so don’t worry too much. We should pay attention to the hygiene of the genitals in normal times, and the underwear should be breathable and comfortable. If you find other abnormal conditions, go to the hospital for examination.
