Chronic untreated epididymitis may lead to the decline of male sexual function, affect the fertility, and induce other urinary system diseases. 1. Decline in sexual function: Because epididymis is an important urogenital organ of men, it is of great significance to men’s health. If it is not effectively treated, it may lead to problems in men’s sexual function. 2. Affecting the fertility function: if chronic epididymitis remains untreated for a long time, it will cause damage to the spermatogenic function of men, which will lead to necrosis and azoospermia, affecting the fertility. 3. Induce other urinary system diseases: chronic epididymitis will also cause a series of complications such as prostatitis, seminal vesiculitis and cystitis. If you have chronic epididymitis, it is recommended that you go to a regular hospital as soon as possible to avoid delaying your condition.
