There are roughly the following reasons:
Viral infection
Virus infection is the most common cause of testicular atrophy of children and adolescents, especially the epidemic mump virus, commonly known as "gill" disease.When the testicles are attacked by this virus, the sperm tissue in the testicles will be destroyed, the testicular volume is reduced, and the texture becomes soft.
Damage or impact
Injurbed scrotum or testicular parts, impact injuries occur, causing scrotal hematoma or testicular laceration. Even if trauma healing, the testicular will be in insufficient blood supply for a long time and atrophic.
Belly severe orchitis
The testicular swelling and pain when the disease can last for many days.Testosomial tissue destruction was caused by bacterial violations, resulting in atrophy of testicular tissue.
Affordance of radioactive substances
Anyone who has a long period of contact with radioactive substances, such as long -term professional personnel such as X -ray and isotopes, if it is not well protected, it will cause testicular atrophy.
Endocrine disease
Testicles are an endocrine organs that mainly produce androgen, and many of them command endocrine organs, such as pituitary gland, adrenal glands, and lower part of the mound brain. They will interfere with the function of the testicles and cause testicular atrophy.
Impact
Long -term use of certain toxic drugs, such as arsenic, or estrogen drugs that repeatedly use antiarophic, such as alumolopol, can cause testicular atrophy.
