Ejaculation is the occurrence of ejaculation when there is no sexual activity. It is common in adolescent males and is generally a normal physiological phenomenon. According to the time of occurrence of spermatorrhea, it can be divided into dreamy emission and spermatorrhea: it occurs during the sleep and dreaming process and is called spermatorrhea when it occurs during waking.
Sperm emission generally occurs after sexual maturity in men, but is rare in men before the age of 12. By the age of 14, the incidence is about 25%, about 55% at the age of 16, about 70% at the age of 18, and up to 80% at the age of 20.
Generally, it is a normal physiological phenomenon. After puberty, the male internal genitalia gradually matures, and the testicles continuously produce sperm. The secretion of accessory gonads such as the epididymis, prostate, and seminal vesicles constitutes seminal plasma. When sperm and seminal plasma are stored to a certain extent, they need to be excluded from the body.
Too little or too much ejaculation can cause distress for young people. It is normal for healthy unmarried men to ejaculate 1-2 times a month. Under normal circumstances, it is common for unmarried men to ejaculate 4-5 times a month. The frequency distribution can be uneven. It is also normal for some people to ejaculate once in 1-2 weeks over a period of time, but repeatedly over another period of time. If ejaculation occurs too frequently, several times a week or several times a night, even when awake, it is important to find the cause.
If there is frequent ejaculation during sexual activity, multiple times a week or even multiple times a night, or if there is sexual desire, it is pathological ejaculation, which may be caused by the following reasons:
Psychological factors, manifested as a lack of sexual knowledge and excessive attention to sexual issues, cause the cerebral cortex to be in a persistent state of excitement and induce ejaculation;
Excessive fatigue, if physical or mental labor is excessive, can also induce ejaculation;
Inflammatory stimuli, such as foreskin inflammation, seminal vesiculitis, or prostatitis, can also lead to ejaculation;
Local stimulation, such as tight clothing and heavy bedding during sleep, can also induce ejaculation by stimulating the external genitalia.
