The frequency of dream emission is considered normal and should be analyzed on a case-by-case basis, not as a generalization. Dream emission is a kind of seminal emission, which occurs when dreaming. Usually, after men enter puberty, they may have 2-3 times a month or 1-2 times a week, which is a normal physiological phenomenon. After puberty, the male body reaches a certain level of androgens, and the functions of the sex organs gradually develop and improve, so the dream emission will be controlled to a certain extent. As long as the dream emission is not accompanied by dizziness, tinnitus, insomnia, palpitation, lumbar and knee weakness, mental depression and other symptoms, you can not worry too much. If the above-mentioned uncomfortable symptoms appear, you can consider visiting the urology department of a regular hospital to be judged by a professional doctor whether there are pathological reasons. It is recommended that men pay attention to physiological hygiene, underwear should not be too tight, avoid excessive tension and fatigue, do not combine work and rest, do not contact unhealthy pictures or books, etc.
