The reason why the testicles are easily injured is that the scrotum hangs the testicles outside the body like a bag and loses the protection of fat. Some people will say that the penis grows outside is a functional need, and the testicles are so fragile that it is inconvenient to ride a bike or sit on a stool, and it is easy to become a fatal hole for the enemy to attack. This is really a major failure of human evolution.
In fact, from a medical point of view, it is mainly because the balls are afraid of high temperature. 36 to 37 degrees Celsius is too high for testicles. One of the functions of scrotum is to make the testicular temperature slightly lower than the body temperature by two degrees, which is higher than the sperm survival.
Because of external reasons, the balls are very fragile parts, and the first thing to avoid is trauma. Ball games, riding injuries or being kicked can cause injuries. Le Jia, for example, was involved in the sliding bar training of fire fighters, and his testicles clung to the pole, resulting in closed testicular injury. Therefore, when a football player launches a free kick, he suddenly becomes a "squatting faction" that protects his balls, that is, to protect his lower body and avoid damaging his testicles.
How serious is the pain of testicular injury? There is a joke that goes around like this: a person can bear the pain of 45del (unit, in fact, dol, the Latin word for pain, dol is its abbreviation), and the pain a woman bears when giving birth is 57del, which is roughly the pain caused by breaking 20 bones. When a man is kicked to the egg, the pain is 9000del, which is equivalent to having 160 children at the same time, or breaking 3200 bones. Although this weird scientific measurement unit has not been recognized by the industry, it is really an unforgettable pain!
Because of the contusion and rupture caused by external force, if the inside of the testicle is still good, then the testicle can be used normally after sewing the outer epidermis. If the testicle is broken, it means that the testicle is broken inside, which will be irreparable and can only be removed or shrunk by itself. The fractured testis loses the function of spermatogenesis. Even if there is no serious trauma, testicular torsion will occur.
Even without any stimulation, just because the testis develops too fast in adolescence, it will also lead to torsion of the spermatic cord. That is, the fixed structure of testis in scrotum is imperfect, and the blood vessels in the system twist and twine together, and the blood does not circulate, resulting in testicular necrosis. Of course, the incidence of testicular torsion is also a small probability event, but once it happens, it is very likely that testicular necrosis will be caused by poor blood circulation in the testis.
Fortunately, if there is only one testicle, and this testicle is healthy and normal, it will not have a great impact on male sexual desire. Many men with only one testicle can still show strong sexual desire and have no obstacles to sexual life.
So even if Le Jia has only one egg left, it will not affect fertility, let alone masculinity. (You can imagine that Bruce Lee didn't become a mother because of this.). Just like a person with a kidney can live a normal life, the attention and care for another person is higher than that of ordinary people. Just as double insurance becomes single insurance, you need to pay special attention to safety.
Fortunately, Mr. Le himself already has a daughter, and even he himself said that he was good at freezing sperm. This is the real rainy day!
Daily, egg health care:
A. the most important thing is: avoid local high temperature for a long time! Don't shower at high temperature for a long time, especially in winter;
B. It is not advisable to sit for a long time. You should walk from time to time, and the sitting posture can be less subtle.
C try to avoid wearing tight and airtight pants for a long time.
D try to wear light-colored underwear, and the material should be comfortable and breathable.
Testis is an important organ that makes you shy. Don't forget to pay more attention to it!
