Ejaculation in dreams is called dream ejaculation, which is a normal physiological manifestation of males after entering puberty. As men enter puberty, androgen secretion is high and gonadal secretion is high. At this time, there will be too much sperm storage, and when it exceeds a certain level, it will happen to discharge itself out of the body. There are usually certain triggers, such as receiving a certain amount of sexual stimulation, or watching something erotic, which leads to a sleep with related images to induce ejaculation. Occasional ejaculation does not require any treatment and is a normal physiological phenomenon. However, if the phenomenon of ejaculation occurs frequently, it is necessary to go to the hospital for further examination to rule out the presence of psychological factors. It is also necessary to check the external genitalia to see if there is local irritation, excessive accumulation of foreskin scale, excessive prepuce, prepuce or glansitis, which causes chronic glans irritation and produces frequent ejaculation.
