The underwear is a little too tight. What should I do?

About "underwear is a little too tight." Don't wear it when sleeping at night, wear it when going out. Does this also affect? " ：

Let's start with the developmental characteristics of testis.

In the embryonic stage, the testis is located behind the peritoneum and the scrotum is not formed. At birth, the scrotum forms and the testicles descend into the scrotum. Why don't testicles hide in the body like ovaries, but hang outside the body? Because the testis is suspended in the vulva wing, the temperature there is lower than that in the body 1.5 ~ 2.5℃. That temperature is conducive to the normal development of testis. If the testicles haven't dropped into the scrotum after the baby is born, it is called cryptorchidism. Because the testes of cryptorchidism patients are in the internal temperature environment, the tissues that produce sperm in their testes cannot develop normally. Experiments have proved that if the temperature of animal testis is artificially raised, the sperm produced by testis will undergo tissue degeneration.

If you wear tight and airtight underwear and squeeze your testicles and penis tightly on the crotch wall, it is not equal to artificially heating your testicles! In addition, the volume of testis and penis increases rapidly during adolescence. The volume of adult testis is 17 ~ 50 times that of prepubescent testis, and the volume of adult penis is 10 ~ 14 times that of prepubescent children. If you add a "spell" to them, won't it hinder their growth?

Second, we should start with the state of the penis. During the day, due to intense study and other activities, coupled with sexual and moral restrictions, the nerves that make the penis erect (which makes the penis stiff after cavernous congestion) are suppressed, and the penis is in a weak state. At night, after the brain is in a state of full rest, the nerves that make the penis erect are often released, so that the penis is in an erection state in waves. The penis erects at night, indicating that its development is in a normal state. Wearing tight underwear will limit penis erection and may lead to frequent nocturnal emission.

If it is in the form of nocturnal emission, it is completely normal physiological phenomenon and can be ignored. But if frequent nocturnal emission is caused by human factors, it is not normal. Frequent nocturnal emission can cause insomnia, dizziness, fatigue, listlessness and other symptoms, affecting study and normal life, and may also cause a certain psychological burden.

Therefore, whether you should wear tight underwear also needs your careful consideration.
