Sperm overflow (refers to spermatorrhea) is not a manifestation of kidney goodness; the appearance of this phenomenon is mainly considered to be related to psycho-psychological factors, somatic disease factors and other factors. 1. Psychological factors: long-term indulgence in pornographic books, videos, often in the erotic impulse; lack of correct sexual knowledge, or the existence of tension, anxiety and other bad moods, can be triggered by seminal emission. 2. physical disease factors: such as phimosis, phimosis, glansitis, adenitis of the seminal vesicles, prostatitis and lumbar spinal cord damage, etc., can also be triggered by spermatorrhea. 3. Other factors: excessive physical weakness, fatigue, frequent sexual intercourse, frequent masturbation, or wearing too tight underwear or too thick bedding may also trigger seminal emission. Occasional occurrence of this phenomenon is mostly considered as a physiological phenomenon; if frequent spermatorrhea, we should be alert to the possibility of disease factors, and must go to the regular hospital as soon as possible to seek medical treatment.
