Why do testicles appear larger sometimes and smaller sometimes?

The testicle is an important male reproductive organ and also the most vulnerable one among male organs. It can affect male fertility. Reproduction and having children have always been the responsibility of men since ancient times, so all men pay special attention to this issue. Some male friends find that their testicles are sometimes big and sometimes small. What's going on? Is it a normal phenomenon? Does it have any impact on physical health?

The testicle is an important organ for maintaining male reproductive function and sexual characteristics. The size of the testicle is related to age. Before the age of 12, the testicle of children is in a relatively quiescent period, and the general volume is 1 to 4 ml. After the age of 12, boys enter puberty and the testicle volume increases rapidly.

The testicular volume of adult males is 16-25 ml, with an average of 19.8 ml. After the age of 60, men enter the aging stage, and the testicular volume gradually shrinks. After the age of 70, the testicular volume shrinks to less than 16 ml.

Does testicle size affect fertility?

If the testicles of adult men are too large or too small, it will affect their fertility to some extent and should be taken seriously. Generally speaking, under normal circumstances, the volume of the testicles is about 15~25 ml and the texture is relatively firm, indicating that the testicles have better spermatogenesis function.

If the testicles are small and soft, it means that the ability to produce sperm may be affected to a certain extent, thus affecting pregnancy. However, this is only a preliminary judgment and requires semen examination for analysis.

If the volume of both testicles of an adult male is less than 10 ml, it is considered microtestis, which may cause sexual dysfunction or male infertility. Too small testicles may cause spermatogenesis disorders, low sperm count or no sperm, which may lead to loss of fertility.

The scrotum will shrink when the surrounding environment is relatively cold and humid. If the testicles have not entered the abdomen, there will be no major problem. The scrotum expands when it is hot and shrinks when it is cold. It appears loose and sagging when it is hot or the clothes are too warm. It shrinks and becomes smaller when it is cold or the clothes are not enough, just like a natural air conditioner, keeping the temperature of the testicles about 15 degrees Celsius higher than the body temperature to ensure the normal production of sperm by the testicles.

Are male friends who have read the above content relieved about this situation? This shows that the testicles are very smart and understand the physical phenomenon of swelling when hot and contracting when cold. The testicles are also easily infected by bacteria, so male friends should pay special attention. Once you feel unwell, go to the hospital for a check-up to make yourself feel more at ease.
