What summer activities are most harmful to the scrotum?

In the hot summer, people always do their best to prevent heatstroke and keep cool. But many men overlook one thing: cooling down the scrotum. Many American surveys show that because modern men sit still for a long time, their scrotum is confined in a narrow space and difficult to breathe, which will increase their own temperature and affect sperm production. At the same time, infertility, which makes many young European men turn pale, is also closely related to their favorite fashion tight underwear. Too tight and non-breathable underwear may also cause problems such as scrotal eczema.

You should know that the scrotal skin is very sensitive to external temperature. When the temperature is low, the smooth muscle and levator testis of the scrotal fascia contract, raising the position of the testicles. The scrotal skin will shrink into dense wrinkles and retract to the perineum to prevent heat dissipation, which helps to keep warm. On the contrary, when the external temperature rises, the smooth muscle and levator testis relax, the testicles will drop and leave the body, and the scrotal skin will relax accordingly, increasing the heat dissipation area, which is conducive to local heat dissipation. The scrotum regulates the temperature inside the scrotum in this way.

But don't underestimate the ability of the scrotum, it is too important for human reproduction. Because temperature has a great influence on the testicular spermatogenesis process. The temperature inside the scrotum is about 2°C lower than the body temperature, which is the most suitable temperature for spermatogenesis; if the temperature is too high, spermatogenesis will be hindered or even completely stopped, and the secretion of testosterone will also decrease. These changes may lead to male infertility or sexual dysfunction.

Therefore, in summer, men should pay special attention to the care of the scrotum, which can be simply summarized as "two more and two less": more activities to give the scrotum more opportunities to dissipate heat; less sitting and less wearing tight underwear. Specifically, it can be divided into the following aspects: avoid long-term exposure to high temperature environment, try not to wear jeans; it is recommended that men take off their outer pants after returning home and wear a loose, thin, breathable cotton underwear; do not sleep on your stomach to avoid squeezing the scrotum, if conditions permit, you can sleep naked; take fewer saunas or hot baths; take a break every hour when driving or riding a car.
