The human testis is a very magical body "part". Proper temperature is an important condition for testicular spermatogenesis. Scrotal contraction can adjust the temperature. When the outside temperature rises, the scrotum will relax and the heat dissipation area will expand. On the contrary, scrotum contracts to keep warm. In the late stage of human fetal development or shortly after birth, testis descends from abdominal cavity to scrotum.
So, how big is a person's testicle to be normal? Of course, due to the differences in objective conditions such as race and figure, the size of human testicles is not the same, but the difference is not great. Medical experts point out that the normal size of male testicles is similar to the size of the circle formed by thumb and forefinger. It is said that a man can put his testicles in place with an OK gesture. If they are too loose or don't close at all, you'd better see a doctor as soon as possible. The importance of testicles to men is self-evident. In fact, if there are no obvious symptoms such as pain, few people will pay attention to whether their testicles are normal.
The long axis of healthy adults' testicles is about 3.5 to 4 cm, and it is also a good method to evaluate themselves with "OK test". Normal testicles should all conform to the arc of the OK gesture. It doesn't matter whether they are a little loose or a little tight. But if testicular atrophy, it may be the cause of infertility. If it can't be inserted at all, it may be testicular disease. You'd better have a urological examination.
It is said that this test method is very encouraging, because few people usually measure the size of their testicles. As soon as they heard that there was such a simple and easy method, they couldn't help but find a deserted place to "measure". The male gonad of human and animals is the organ that produces sperm and secretes male hormones. The human testis is an oval entity with a smooth and tough white film on its surface. The white membrane goes deep into the testis and divides it into many conical lobules. Leaflets are filled with curved seminiferous tubules in which sperm are produced. The stratified epithelium of seminiferous tubules consists of seminiferous cells and sertoli cells. Interstitial cells between seminiferous tubules can secrete androgens.
Testicular spermatogenesis begins in adolescence (average age 15 years old) and gradually declines or even stops in old age. The human testis is a very magical body "part".
