What is the normal size of a boy’s testicles?

“"Testicles" refer to men's testicles. The testicles are the processing plants that produce sperm and mainly metabolize male hormones. In normal men, the size of the testicles on both sides is not exactly the same. According to the survey, the male testicles on the right side are slightly larger than those on the left side. Even among people of the same age group, the size of the testicles is quite different. However, in adult men, the volume of testicles is above 15ml and not less than 12ml, and its functions are normal. You can know the size by just touching it through B-ultrasound examination or physical examination by a professional doctor.

In clinical medicine, we often encounter some adult men whose testicles are smaller than ordinary people, so they are worried about affecting male sexual and reproductive functions. In fact, it is not possible to draw a conclusion as to whether small testicles will affect male sexual and reproductive functions, and it requires in-depth analysis based on the actual situation.

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

The average man's male testicles are different in size on both sides, but the difference is generally not very big. Some men's testicles have had different sizes on both sides since childhood, and the difference is sometimes very obvious. This may be caused by congenital diseases. Small testicles on one side may cause compensatory enlargement of the male testicles on the same side, further increasing the size difference between the two testicles. If the testicles on both sides were basically similar in size in the past, but one testicle suddenly appears to be significantly enlarged recently, you should go to the hospital for examination immediately. When one side of the testicle is enlarged and accompanied by fever and local pain, it may be epididymitis or orchitis. If testicular enlargement is not accompanied by any symptoms, you should consider whether there is a testicular tumor, and you should check it in time and don't leave it to chance.

Trauma, mumps virus infection and erosion can cause testicular atrophy, thus causing the testicles on both sides to become smaller. In addition, the enlargement or reduction of the vagina caused by disease of tissues other than the testicles should be distinguished from testicular disease.
