The harm of chronic epididymitis lies in: 1. Chronic epididymitis is prolonged and the course of the disease is long, which seriously affects the daily work and life of the patients, and increases the economic burden and psychological burden of the patients, and it may be complicated by acute infections, which affect the testicles, and the function of the testicles will be affected in serious cases. 2. In patients with chronic epididymitis, the bacteria will pollute the seminal vesicles, prostate gland, and urethra during sperm discharge, which will be complicated by vesicoureteritis, prostatitis, and urethritis etc. 3. In patients with chronic epididymitis, the epididymal tubules and vas deferens may be blocked by inflammatory substances, thus affecting the discharge of sperms from the body, and if the disease is bilateral, it may cause sterility. Therefore, patients with chronic epididymitis should be treated timely, early and standardized to avoid serious adverse consequences.
