What is the normal size of male testicles?

The testicles of a normal adult are approximately 4.5*3*2.5cm. Convert the volume of testicles to about 12~37ml.

When the testicular volume is less than 13ml, it usually indicates that the testicular volume is small, which may be caused by congenital testicular dysplasia or testicular atrophy. Under normal circumstances, it can be treated with testosterone propionate, testosterone undecanoate capsules and other drugs. If the testicular volume is significantly larger than before, you should consider whether acute inflammation, trauma or other reasons have caused the testicular enlargement. If this happens, you should go to the hospital for further examination.

In addition, for newborns or children, the testicle size is smaller, mainly because the testicles have not yet begun to develop at this time, and the level of testosterone produced by the testicles is low. Compared with adolescence, the testicular volume of older men is also smaller than that of younger men, which is related to the lower level of androgen secreted by the testicles. If the ultrasound is normal, secretion of androgens is normal, and fertility is normal, even if the size is too small, it can be normal.
