Why do my testicles become smaller?

The testicle is a very important organ for men. Its main function is to produce and store sperm. Once the testicle is abnormal, it often leads to loss of fertility. Sometimes the testicle will become smaller. So what is the reason?

What do normal testicles look like?

To know whether the testicles are normal, let's first learn about the relevant knowledge of the testicles. Before the age of 10, the testicles are in a relatively dormant stage, usually only 1-3 ml. After the age of 10, children enter puberty and the testicles grow rapidly. At the age of 17 or 18, the volume of the testicles can reach the normal adult level. The testicle volume of Chinese adult men is 12-25 ml, which is slightly smaller than that of Western white people.

After the age of 60, men enter the stage of sexual aging and the testicle volume gradually shrinks. Based on these normal values, as long as the testicle volume is measured, it is possible to compare whether the size of the testicle is normal.

Will smaller testicles cause infertility?

The testicles are responsible for the production of sperm, so if they become smaller, it means that your fertility will decline or even become infertile. The smaller the testicles, the greater the possibility of no sperm and the greater the possibility of not being able to produce offspring. The normal testicle size of yellow men is 15-25 ml per side, the testicle size of white men is about 20-30 ml, and the testicles of Africans are larger. If it is less than 12 ml, it may lead to low spermatogenesis, and even smaller testicles will lead to loss of fertility.
