In real life, the testicle refers to the male reproductive organ, and the testicle is very important to the male reproductive organ. If the testicle has a disease, it will easily affect the quality of semen and easily cause some diseases of the reproductive system. Testicular displacement is also a common symptom, which may be caused by the elongation of the testicular frenulum and requires surgery for treatment. What to do if the testicles are dislocated? reason 1. The frenulum of the testicle is too long, causing the testicle to move up and down to a large extent. In this case, the testicle can easily twist, causing pain and testicular necrosis. 2. Incomplete cryptorchidism: Although the testicles have descended into the scrotum, the testicular frenulum has not formed, so the testicles can still move with the contraction of the spermatic cord. If they are not in the scrotum, the possibility of malignancy is very high, and it often affects the spermatogenesis function. If this is the case, you should have surgery and go to the urology department of the hospital. Structural characteristics The surface of the testicle is covered with a thick fibrous membrane called the tunica albuginea. The tunica albuginea thickens along the posterior edge of the testicle and protrudes into the testicle to form the testicular septum. From the septum arise numerous connective tissue septa that divide the testicular parenchyma 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. Spermatogenesis The internal structure of the testis is wrapped by a layer of tough tissue on the outside, called the white membrane, which protects the testis. The white membrane thickens and extends inward, dividing the testis into many small chambers, which are called testicular septa and testicular lobules. Normal men generally have 200 to 300 lobules, which are filled with testicular parenchyma, where sperm is produced, called seminiferous tubules. If a small piece of testicular parenchyma is cut and placed under a microscope for observation, it can be seen that the seminiferous tubules are thin tubes. |
