Are all human testicles the same size?

Testicles are an important part of the male body. Although for male friends, even if the testicles are missing, it will not affect the male's sexual function and erection, but if the testicles are missing, it will have a serious impact on the male's sperm. Because the main function of the testicles in the male body is to store and produce semen, but are the testicles of every man the same size?

The human testicle is a very magical body part. 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.

So, what is the normal size of human testicles? Of course, due to differences in objective conditions such as race and body shape, human 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.

The importance of testicles to men is self-evident. In fact, if there are no obvious symptoms such as pain, few people pay attention to whether their testicles are normal. The long axis of the testicles of healthy adults is about 3.5 to 4 cm. Normal testicles should be able to fit into the arc of the OK gesture. It is not a big deal if they are a little loose or a little tight.

However, if the testicles are atrophied, it may be the cause of infertility. If they cannot be inserted at all, it may be a testicular disease. It is best to see a urologist for examination. It is said that this test method is very encouraging, because few people usually measure the size of their testicles. When they hear about such a simple and easy method, they can't help but find a deserted place to "measure" it.

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.
