Ejaculation in the twenties may be a normal physiological phenomenon, or it may indicate an abnormality, such as local inflammatory lesions, central nervous system lesions, external stimuli, and so on. 1. Normal physiological phenomenon: some men with delayed puberty, or no masturbation habits and no sex life for a long time, semen leakage in his twenties may also occur, generally belong to physiological phenomena, do not need to worry too much. 2. Abnormal phenomenon: (1) Local inflammatory lesions: local infections of the sex organs or urinary system, such as phimosis, phimosis, urethritis, prostatitis, etc., these lesions can stimulate the sex organs and spermatorrhea. (2) central nervous system lesions: when the cerebral cortex is not functioning properly, it loses its inhibition of the sex center, leading to increased excitability of the erection and ejaculation centers, which can trigger seminal emission. (3) external stimulation: sleeping with too thick a blanket, too tight pants, too hot a blanket, cold feet, may induce spermatorrhea. If you are in your twenties and suffer from prolonged spermatorrhea, you should consult a doctor to clarify the cause of the disease and carry out relevant treatment if necessary.
