With the significant improvement in the quality of life, people have higher requirements for food, drink, and clothing. However, many people easily neglect their underwear. In life, people do not have much demand for underwear as long as it is comfortable, but they do not know that tight underwear has become a new sperm killer and one of the factors contributing to male infertility.
Sperm survival time varies at different temperatures
The scrotum of the male sexual organ is surrounded by the testicle, which is the place where sperm is produced. Therefore, the most suitable temperature for sperm to survive is the temperature in the human body, which is 36.0 ℃ - 37 ℃. It is understood that sperm live for more than 4-8 hours in an environment of 37 ℃; The survival time of active in the vagina is 0.5 days; The active survival time in the cervix is 2-8 days, and the active survival time in the uterus and fallopian tubes is 2-2.5 days. It can be seen that the survival time of sperm is directly affected by temperature. The higher the temperature, the faster the sperm death rate.
Underwear can cause testicular temperature to rise sharply, strangling sperm
Whether the testicle produces sperm in the scrotum or the sperm survives in the body, it is affected by temperature. Because of this, in hot summer, the scrotum will relax; When the weather is cold, the scrotum will shrink into a crumpled small mass, tightly cling to the body, and adjust itself as the temperature changes. However, this balance has been damaged by tight underwear, tightly wrapping the scrotum, leaving it in a closed state. The lack of air circulation prevents the scrotal skin from radiating heat and cooling, thereby affecting the physiological function of the testicle, and it is possible to produce abnormal sperm, or even unable to produce sperm. At the same time, tight underwear restricts blood circulation, hinders the return of spermatic veins, and is very detrimental to sperm production and nutrition. In the long run, it can easily lead to adverse consequences of infertility in the future.
It is worth noting that the choice of underwear varies depending on individual circumstances. For example, for men who sweat a lot, pure cotton may not be the best choice. "Although pure cotton underwear absorbs sweat, it is not easy to dry, especially in summer. The sticky sensation of the vulva is not only uncomfortable, but can also cause scrotum inflammation, which can lead to itchy and painful reproductive system diseases.". Therefore, men should not be careless in choosing underwear, and comfort and appropriateness are the key points.
