Ejaculation during sleep is a normal phenomenon. The reason for this is that the body is too tired after overexertion, and when the body enters deep sleep, the muscles of the whole body relax, and thus seminal emission occurs. If you do not have sex for a long time, it will lead to excessive storage of semen in the seminal vesicles, and the elevated pressure in the seminal vesicles will discharge the excess semen through the ejaculatory ducts. If the sensitivity of the penis is too high, the underwear fibers and materials are too rough will rub the glans and cause the body to develop an ejaculatory reflex. The normal frequency of ejaculation is about 3-4 times a month, more than this frequency belongs to the pathological state, it is necessary to be examined and treated. It is recommended to go to the urology department of the regular hospital and complete the relevant examinations, and can be treated by taking western medicine and Chinese medicine soup.
