The secret of “balls”: what size is normal for testicles?

It is said that the penis is a male-specific organ, which is not wrong in itself. However, compared to the penis, the testicles also have a very special side and are also a male-specific organ. I believe that many men do not know much about testicles. What is the normal size of testicles?

What is the testicle

The male reproductive glands of humans and animals are organs that produce sperm and secrete male hormones. Humans have one testicle on each side, which is an oval solid body covered with a smooth and tough white membrane. The white membrane penetrates deep into the testicle and divides the testicle into many cone-shaped lobules. The lobules are filled with tortuous seminiferous tubules, where sperm is produced. The stratified epithelium in the seminiferous tubules is composed of spermatogenic cells and supporting cells. The interstitial cells between the seminiferous tubules can secrete male hormones. The spermatogenic function of the testicle begins in puberty (average age 15), gradually declines in old age, and even stops completely.

Testicles are magical body parts

The human testicle is a very magical "part" of the body. Appropriate temperature is an important condition for sperm production in the testicle. The expansion and contraction of the scrotum has the function of regulating temperature. When the external temperature rises, the scrotum expands to expand the heat dissipation area; conversely, the scrotum shrinks to keep warm. In the late stage of fetal development or shortly after birth, the testicles of humans descend from the abdominal cavity into the scrotum.

What is the normal size of human testicles?

Of course, due to differences in objective conditions such as race and body shape, people's testicles are not the same size, but the difference is not great. Medical experts point out that the normal size of a man's testicles is about the same size as the circle formed by the thumb and index finger. It is said that men only need to make an OK sign to put on the testicles. If it is very loose or cannot be inserted at all, it is best to see a doctor as soon as possible.
