Under normal circumstances, men may experience sperm overflow 1-2 times a month, the exact number and timing of which are related to each individual’s physical condition and cannot be generalized. During puberty, men’s testicles secrete a large amount of androgens, which can promote the production of a large number of sperm, which together with seminal plasma make up semen. When the semen reaches a certain saturation state, after being stimulated by the outside world, the cerebral cortex’s will to sex decreases and can be discharged by way of seminal emission, i.e. “seminal overflow”, which is a normal physiological phenomenon and may occur 1-2 times a month, mostly during sleep. In adult men, it is mainly caused by long-term sexual inactivity. If it occurs frequently, you need to pay attention to more rest and not to overexert yourself. In addition, inflammation can also persistently stimulate the glans and cause seminal emission, which should be treated promptly in a hospital. If semen cannot be released for a long time, it can easily cause impotence, prostatitis, etc. The quality of semen becomes poor and can also lead to psychological problems.
