What is the normal size of testicles for men?

"Testicles" refers to the male testicles, which are the factories for producing sperm and metabolizing male hormones. In normal men, the size of the testicles on both sides is not exactly the same. According to surveys, the right testicle is slightly larger than the left one, and even for people of the same age, the size of the testicles is quite different. However, in adult men, the volume of the testicles is more than 15ml and not less than 12ml, and its function is normal. The size can be understood by ultrasound examination or physical examination by a professional doctor.

1. Is it not okay if the testicles are small?

In clinical medicine, we often encounter some adult men whose testicles are smaller than normal people, so they are worried about affecting their sexual and reproductive functions. In fact, it is not possible to draw a conclusion whether small testicles will affect male sexual and reproductive functions. It still needs to be analyzed in depth in combination with the actual situation.

There are many reasons for small testicles. If physiological testicles are small, there is no need to worry too much as long as they do not affect body functions. Physiological testicular shrinkage should be taken seriously. If the spermatogonia or spermatocytes of the seminiferous tubules are involved, sperm cannot be produced or normal sperm cannot be produced. If the interstitial cells that metabolize androgens are involved, the growth and development of male genitalia and male secondary characteristics (such as beard growth, lower voice, prominent Adam's apple, firmness, etc.) may be affected. The most common diseases that may cause physiological testicular shrinkage include viral infection orchitis, taking a lot of estrogen, hypopituitarism and persistent high fever.

2. The male testicles are not the same size. Is that okay?

The testicles of ordinary people are not the same size, but the difference is generally not very big. Some people's testicles are different in size since childhood, and the difference is sometimes very obvious. This is often caused by congenital symptoms. The small testicle on one side may cause the compensatory enlargement of the testicle on the same side, which further increases the difference in the size of the testicles on both sides. If the testicles on both sides used to be similar in size, and one side suddenly enlarged significantly recently, you should go to the hospital for examination in time. When one side of the testicle is enlarged, accompanied by fever and local pain, it may be epididymitis or orchitis. If the enlarged testicle is not accompanied by any symptoms, you should consider the possibility of testicular tumors and check it in time without any hesitation.

Traumatic and mumps virus erosion can cause testicular atrophy, which in turn causes the testicles to be different in size. In addition, scrotal enlargement or shrinkage caused by lesions in tissues other than the testicles in the scrotum should be distinguished from testicular lesions.
