One testicle on top and one on the bottom

Every man attaches great importance to the health of his testicles. After all, only healthy ones can defend their rights as fathers. However, in real life, many people suffer from testicular diseases. So is it normal to have one testicle on top and the other on the bottom? In fact, it should be said that this is the normal position of normal male testicles. If there are no other abnormal symptoms, there is no need to worry too much. Let's learn about common knowledge related to testicles below.

Normal male testicles are usually one large and one small, one high and one low, so don't worry too much. Moreover, the height of the testicles will change with the temperature. When the temperature is low, the testicles will shrink and pull closer to the abdomen. When the temperature is too high, the testicles will drop to enhance heat dissipation.

If the testicles are inside the scrotum, there is no problem, it is not a matter of height. If not, an ultrasound must be done to confirm the location of the testicles to determine whether it is abnormal.

The surface of the testis is covered with a thick fibrous membrane called the tunica albuginea. Along the posterior edge of the testis, the tunica albuginea thickens and protrudes into the testis to form the septum testis. From the septum testis, many connective tissue septa extend and divide the testicular substance into many testicular lobules.

The testicular lobule contains the convoluted seminiferous tubules, the epithelium of which can produce sperm. The connective tissue between the tubules contains interstitial cells that secrete male hormones.

The seminiferous tubules combine to form the straight tubules, which enter the testicular septum and interweave to form the rete testis. From the rete testis, 12 to 15 efferent ductules emerge, exiting the upper part of the posterior edge of the testis and entering the epididymis.

Testicles are male internal reproductive organs. Normal men have two testicles, one on the left and one on the right side of the scrotum. Testicles are oval and grayish white. Adult testicles are 3.5-6 cm long, 2.3-4 cm wide, 2-2.8 cm thick, and each testicle weighs 16-67 grams. Generally, the left testicle is about 0.5 cm lower than the right testicle. Some people have one testicle that is larger than the other, or one that is higher than the other. If the difference is not too big, it is normal.

There are a large number of curved seminiferous tubules in the testicles, which contain interstitial cells. The seminiferous tubules are where sperms are produced. The number of sperms produced in a person's lifetime is astonishing. One ejaculation of 3-4 ml contains 300-400 million sperms, and as few as 100-200 million. The number of sperms produced in a lifetime can reach more than 1 trillion. The production of sperms is easily affected by many factors such as temperature. If the temperature around the testicles is too high or affected by chemical toxins, sperm production will be hindered.

Interstitial cells produce androgens, which are closely related to male secondary sexual characteristics and physiological functions.

When the testicles descend from the inguinal canal, they may not descend into their normal position in the scrotum, causing ectopic testicles. Ectopic testicles are rare, and their clinical significance and treatment principles are generally the same as those of occult testicles. If the diagnosis is clear, surgical treatment should generally be considered, because androgen therapy is generally ineffective. Orchiopexy as early as possible before puberty can usually restore normal testicular function.
