Seminal emission is a condition in which semen is spontaneously emitted without sexual intercourse, and there are physiological and pathological differences. In Chinese medicine, the phenomenon of semen ejaculation is called semen emission or semen loss. If you have a dream but shed semen, it is called “dream sperm”; if you shed semen without a dream or even shed semen on your own when you are awake, it is called “slippery semen”. Most of them are caused by kidney deficiency, or heart-kidney disconnection, or damp-heat injection. In western medicine, it can be seen in circumcision, prepuce, urethritis, prostate disorders and so on. Dreaming and spermatorrhea is often the first stage of waking spermatorrhea, and dreaming and spermatorrhea are two different symptoms of spermatorrhea with different severity. It should be noted that seminal emission is not menstruation, so there is no regularity to seminal emission. It is normal to have seminal emission before, but now it has disappeared. Especially when men enter middle age, it almost ceases to occur.
