What is the normal size of testicles?

Most male friends do not know how to take care of their testicles, and they always have problems of one kind or another. This will naturally lead to serious consequences. They may even feel that their testicles are swollen. In fact, the normal size of testicles is not that big. If they are too big, it may be due to testicular swelling or other diseases. You must closely observe changes in your body.

The testis is located in the scrotum, one on each side, and the left side is generally 1 cm lower than the right side. The testis is slightly flattened oval with a smooth surface, divided into inner and outer sides, front and back edges, and upper and lower ends. The front edge is free; the back edge has blood vessels, nerves and lymphatic vessels entering and exiting, and is in contact with the epididymis and the testicular part of the vas deferens. The upper end and the back edge are attached to the epididymis head, and the lower end is free. The outer side is convex and the inner side is flat. The testis grows rapidly with sexual maturity, and shrinks and becomes smaller with the decline of sexual function in old age.

The testicles need to maintain normal physiological functions at an optimal temperature of about 35 degrees Celsius, while a body temperature of 37 degrees Celsius is harmful to their functions. Some patients with cryptorchidism (embryo development disorders cause the testicles to fail to descend to the scrotum normally) have their testicles in an environment of excessively high temperatures for a long time, and their testicles cannot function normally. Their sexual functions are very poor or even nonexistent.

Since the testicles have high requirements for temperature, the scrotum is responsible for regulating the temperature of the testicles. When the temperature of the testicles is too low, the scrotal skin contracts to prevent heat loss; when the testicles are overheated, the scrotal skin relaxes to dissipate heat. Men should be able to easily understand the above changes in their scrotum.

But it must be clear that the temperature regulation function of the scrotum has certain limits. When the temperature changes beyond its regulation range, the physiological function of the testicles will inevitably be damaged. Therefore, be kind to your testicles, because this will affect the heat dissipation of the testicles. Similarly, sitting on a loose sofa for a long time will also affect the heat dissipation of the lower body. In daily life, it is recommended to wear slightly loose pants and keep the lower body ventilated and dry, so that the testicles have a relaxed working environment, so that they can play the greatest physiological function. There are "sac bag" underwear on the market, which can effectively assist in heat dissipation and maintain a healthy testicular environment.
