Occasional seminal emission has no effect on men’s health, but seminal emission caused by diseases is not beneficial and needs to be treated for the cause. Semen leakage generally refers to the situation that semen flows out by itself when there is no sexual intercourse. Generally, during the metabolic period of young and middle-aged men, the testes generate a large number of sperms, which gradually mature in the epididymis and are finally stored in the seminal vesicles, while semen, which is constantly being produced but unable to be discharged, overflows due to overfilling, which is known as spermatozoa. It is usually a normal physiological phenomenon, which can improve the lower abdominal swelling caused by excessive semen, and also reduce bad habits such as excessive masturbation. However, other pathological causes can also cause seminal emission, such as phimosis, prepuce, urethritis or congenital underdevelopment. If frequent seminal emission is accompanied by other uncomfortable symptoms, it is recommended to consult a doctor to clarify the cause of the problem and follow the doctor’s instructions.
