It turns out that men's underwear can harm a man. The thing 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 the temperature of the body, for this they are brought out. If the temperature of the testicles is equal to and higher than body temperature, then there will come "death" to testosterone and sperm. Therefore, tight-fitting underwear harms the sexual health of men.
This can be confirmed by the fact that in such a densely populated country as India, men wear the so-called sarongs, which give complete freedom to the testicles. These include Arabs, Chinese with their free pants.
In order not to interfere with the production of sperm and testosterone, a man should walk in wide underpants, preferably from cotton material, in no case not in synthetic ones, as synthetic fabric "does not breathe", producing excessive heating. At night you need to sleep without panties. Care must be taken to ensure that the testicles remain in the free hanging, rather than being pressed by underwear to the body.
Such “pests” for men’s sexual health include tight jeans, mobile phones on their belts or in trouser pockets, a working laptop on their knees, etc.
