Symptoms caused by holding back semen include seminal emission, impotence, and prostatitis. 1.Semen loss:Men holding back their semen will cause the prostate sphincter to be pressurized, leading to muscle degeneration and inability to control semen, resulting in semen loss. 2. Impotence:If the ejaculation process is forcibly terminated, it will result in the flow of semen back, but the reproductive organs and central nervous system are still continuously excited. Holding back the semen for a long time will reduce the sensitivity, resulting in the penis not being able to have a normal erection, resulting in impotence. 3. Prostatitis:The prostate gland is very close to the urethra, and holding back semen will lead to semen reflux. The semen reflux will impact the prostate gland, causing inflammation and infection.
