How big is a normal testicle?

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

The testicles (testis) are located in the scrotum, one on each side. Generally, the left side is slightly lower than the right side by 1cm. The testis is a slightly flat oval with a smooth surface, divided into inner and outer sides, front and back edges, and upper and lower ends. its leading edge is free ； The posterior edge has blood vessels, nerves and lymphatic vessels entering and exiting, and is in contact with the testicular part of the epididymis and vas deferens. The upper end and posterior edge are attached to the head of the epididymis, and the lower end is free. The outer surface is more convex and the inner surface is flatter. The testicles grow rapidly with sexual maturity, and shrink and become smaller as sexual function declines in old age.

In order for the testicles to maintain normal physiological functions, the optimal temperature it requires is about 35 degrees Celsius, and a body temperature of 37 degrees Celsius will damage its function. Some patients with cryptorchidism (embryonic development disorder that causes the testicles to fail to descend to the scrotum normally) have poor or even no sexual function because their testicles have been exposed to excessively high temperatures for a long time.

Since the testicles have high temperature requirements, the scrotum takes on the important task of regulating the temperature of the testicles. When the temperature of the testicles is too low when exposed to cold, the scrotal skin contracts to prevent heat loss; when the testicles are overheated, the scrotal skin relaxes and dissipates heat. Men should 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 regulatory range, the physiological functions of the testicles are inevitably damaged. So, 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 also affects the heat dissipation of the lower body. In daily life, it is recommended to wear slightly looser pants and keep the lower body ventilated and dry so that the testicles have a relaxed working environment and can maximize their physiological functions. There are "bag" underwear on the market, which can effectively assist in heat dissipation and maintain a healthy testicular environment.
