It turns out that men's underwear can harm a man. The fact is that for the normal functioning of the male genital organs, in particular the testicles, a certain temperature is necessary. The temperature of the testicles should be 3.3 degrees lower than body temperature, for this they are brought out. If the temperature of the testicles is equal to and higher than body temperature, then testosterone and spermatozoa will die. Therefore, tight-fitting underwear damages the sexual health of men.
This can be confirmed by the fact that in such a densely populated country as India, men wear so-called sarongs, which give complete freedom to the testes. Here you can take the Arabs, the Chinese with their free pants.
In order not to interfere with the production of sperm and testosterone, a man should walk in wide underwear, preferably of cotton material, not in any way synthetic; synthetic fabric "does not breathe", producing extra heat. At night you need to sleep without panties. It is necessary to take care that the testicles remain in the free vis, and not pressed underwear to the body.
Such “pests” of the sexual health of a man include skinny jeans, mobile phones on a belt or in trouser pockets, a working laptop on the knees, etc.
