The human body has many organs, which one is the cleverest? Medical experts have discussed this interesting question. As a result, the testicle is recognized as the "smartest organ".
In some dialects of China, because the shape of testicles is similar to eggs and other eggs, testicles are often called "eggs"; When you describe a person who is very capable and capable, but also smart, exposed and publicized, you will say that he is very "capable".
In fact, the testicle is indeed a "capable" organ. First of all, it knows the cold and the heat. The testicles are hidden in the scrotum. When the weather is hot, it will adjust the scrotum to relax and speed up heat dissipation; When the weather is cold, the scrotum will tighten and lift to save heat and reduce heat dissipation. In this way, according to the environmental temperature, the testicles can keep themselves at the best temperature at all times.
Secondly, the testicles also have a strong sense of self-protection. When humans are in a tense and dangerous state, the testicles will quickly lift up and be tightly wrapped by the scrotum to avoid danger.
Finally, the testicle is still an active molecule. It does not follow the movements of the scrotum and body. When a posture is tired, it will move its muscles and bones by itself. If you observe carefully, you can find that the testicle will twist in the scrotum.
The testicle is not only smart, but also the "lifeblood" of men. From a medical point of view, the role of testicles in human body is mainly to produce sperm and androgens. Two testicles can produce 70 million - 1 per day. There are 500 million sperm, which bear the heavy responsibility of inheriting the family, and its importance is self-evident. Androgen is an important material to form and maintain male characteristics. A normal man can only win the praise of "strong, brave and enterprising" under the action of androgen. Androgens also stimulate the growth, development and maturation of male organs such as epididymis, prostate, penis, and stimulate and maintain the secondary sexual characteristics of men, such as strong bones, developed muscles, deep and thick voice, prominent laryngeal nodes, long beard, etc.
