Varicocele testicular atrophy is usually caused by testicular nutritional disorders, higher temperatures, endocrine disorders and other reasons. 1. Testicular nutritional disorders: Testicular nutritional disorders will lead to the obstruction of venous blood flow, resulting in the emergence of varicocele, causing damage to the testicles, thus leading to the emergence of varicocele testicular atrophy. 2. Higher temperatures: Elevated testicular temperatures can lead to degeneration and atrophy of spermatogonia, resulting in varicocele, and then gradually developing into testicular atrophy. 3. Endocrine disorders: endocrine disorders will lead to abnormal hormone secretion, resulting in decreased sperm vitality, and at the same time, damage to testicular interstitial cells, leading to the emergence of varicocele testicular atrophy. It is recommended that patients go to the hospital for examination in a timely manner and always pay attention to body care.
