For many male friends, ejaculation is an instinctive reflex. However, for some adolescent boys with immature sexual functions, they are actually very curious about ejaculation. Many children ask: How can sperm be ejaculated? Today we will explain the process of male ejaculation from a professional perspective. We hope that everyone can learn more about physiological knowledge and do a good job of safety and hygiene. Male ejaculation is one of the important processes of human reproduction. The following is a scientific explanation of the ejaculation process. First, before erection, the testicles will undergo cell division to produce sperm, which will produce semen. When stimulated psychologically or physically, the penis will become erect, and then the penis will continue to be excited through friction and other means. At this time, the bulbourethral gland will secrete fluid as a lubricant. When the stimulation is strong enough, the vas deferens will send sperm to the posterior urethra to prepare for ejaculation. Under the lubricating effect of the bulbourethral gland secretion, sperm and prostatic fluid are discharged together. 1 Sperm division is relatively fast, and the number of sperm contained in the semen of one ejaculation is hundreds of millions. The testicles will produce sperm autonomously, and they usually accumulate in the vas deferens. This is to prepare for later ejaculation. When the amount of sperm in the vas deferens reaches a certain amount, it needs to be discharged. 2 When a man is psychologically stimulated, or his penis is physically stimulated, the arteries of the penis dilate, the veins contract, and under the pressure, the penis becomes engorged and erect. With continued stimulation (usually rubbing the penis), the bulbourethral glands secrete fluid as a lubricant. 3 When the stimulation is strong enough, the epididymis' vas deferens will contract, sending semen to the posterior urethra (at this time, the urethral bulb secretion plays a lubricating role), the seminal vesicle contracts, and the seminal vesicle secretion and prostatic fluid are discharged from the urethra along with the sperm. This process is usually accompanied by great pleasure. Note: When sperm accumulates to a certain amount in the vas deferens, it needs to be discharged in time, otherwise it may affect the imbalance of hormone secretion in the body. Of course, it is not good to discharge too much. After ejaculation, due to the sudden air pressure, the penis cannot erect again in a short time. |
