The difference between seminal emission and spermatorrhea is that seminal emission is a normal physiological phenomenon, while spermatorrhea is a pathological phenomenon. Slippery semen is discharged on its own in dreams without sexual stimulation or in the waking state. Frequent will lead to dizziness, mental depression, long time will lead to premature ejaculation, impotence and other sexual dysfunction. It usually occurs in men who are addicted to tobacco and alcohol, irregular work and rest, and high stress, and is an abnormal pathological manifestation. Ejaculation, on the other hand, is the excretion of semen without sexual intercourse or masturbation, and usually occurs during sleep with sexual stimulation. The vast majority of adolescents experience seminal emission. It is normal to experience it once every 1 to 2 weeks. When the slippery semen occurs, we should adjust the routine of life as soon as possible, and go to the hospital as soon as possible once there is discomfort, so as not to delay the condition.
