The testicle is a slightly flattened ellipsoid with a smooth surface, divided into inner and outer sides, anterior and posterior edges, and upper and lower ends. The front edge is free; the rear edge has blood vessels, nerves and lymphatic vessels entering and exiting, and is in contact with the epididymis and the lower part of the vas deferens (testis). The testicles grow rapidly with sexual maturity, while the testicles of older men shrink and become smaller as their sexual function declines. Generally speaking, the scrotum will shrink when it is stimulated by excessive cold. This is normal and does not constitute testicular atrophy. Testicular atrophy in medicine means that the testicles were originally normal, but gradually shrank due to some reasons. The reasons are roughly as follows: Testicular atrophy: Viral infection Viral infection is the most common cause of testicular atrophy in children and adolescents, especially the mumps virus, commonly known as "mumps" disease. When the testicles are attacked by this virus, the spermatogenic tissue in the testicles will be destroyed, the testicles will shrink in size and become soft. Testicular atrophy: injury or impact Injury to the scrotum or testicles: Impact injuries may cause scrotal hematoma or testicular laceration. Even if the wound heals, the testicles will be in a state of insufficient blood supply for a long time and will atrophy. Inflammation Severe orchitis When the disease occurs, the testicles are swollen and painful, which can last for several days. Bacterial invasion causes testicular tissue destruction, leading to testicular tissue atrophy. Anyone who is exposed to radioactive substances for a long time, such as those who work with X-rays, isotopes, etc. for a long time, may develop testicular atrophy if they are not well protected. Endocrine diseases The testicle is an endocrine organ that mainly produces androgens. Diseases of many endocrine organs in the body, such as the pituitary gland, adrenal glands, and hypothalamus, can interfere with testicular function and cause testicular atrophy. Drug effects Long-term use of certain toxic drugs, such as arsenic, or repeated use of estrogen drugs that fight androgens, such as ethidol, can cause testicular atrophy. |
