Suggestion: Scrotum not only reduces its function as an external barrier, but also has a peculiar function of regulating temperature from the perspective of fertility to protect the testis inside at a suitable temperature. As long as you observe carefully, you can find that when you are in a cold environment, the scrotum skin will shrink and thicken, which will make the scrotum tense and reduce the surface area. At this time, the temperature of testis in scrotum can be protected from decreasing. On the contrary, in the high temperature environment, the scrotum skin naturally relaxes and shrinks, making the scrotum droop and increasing the surface area. At this time, it is beneficial to radiate body temperature, prevent the temperature in scrotum from rising, and protect testis from producing sperm in a suitable temperature environment. Therefore, the contraction and relaxation of scrotum is a normal physiological regulation phenomenon. This is true of all men with normal development.
Because many people don't understand this truth, they often see their scrotum contract and relax, which leads to misunderstanding. For example, some men mistakenly think that the scrotum is smaller and the testicles are smaller, and even mistakenly think that they are stunted and afraid of infertility. In fact, this situation is just an illusion caused by the function of scrotum lifting and contracting, which makes the testicles rise close to the groin and not easy to touch all. Some people mistake scrotal prolapse as a sign of weakened sexual ability, and they are worried, which is even more nonsense.
Physical fatigue, weaker sexual function than ordinary people, may be due to other aspects of the body, or it may be because of too much work pressure and mental fatigue. In this regard, find the reason, pay attention to adjustment, strengthen exercise, you can slowly recover.
