Men engage in sexual intercourse, from erection to intercourse, and the end result is ejaculation. So have you ever thought about how ejaculation actually happens? The seemingly simple action actually has a complex physiological process. Normal ejaculation is a complex physiological reflex process involving the nervous system, the endocrine system and the urogenital system. 1. Ejaculation is a reflex arc: the nerve receptors in the skin of the penile foreskin ties in the process of sexual intercourse to obtain sexual stimulation transmitted to the center, the center will feedback signal transmission to the posterior urethra caused by the prostate seminal vesicles testes ejaculatory duct contraction, ejaculation in the posterior urethra, causing the posterior urethra pressure to increase, the signal is again transmitted to the center, causing the posterior urethra pressure to further increase, continuous feedback and negative feedback, and finally reach the ejaculation threshold This causes ejaculation. The above medical terms do not understand it, it does not matter an analogy: the penis is like a gun, semen is a bullet, pull the trigger to give the bullet power, the moment the bullet shot out is the ejaculation is complete! 2. what is the product of ejaculation? The product of ejaculation is of course “sperm”, i.e. semen is formed by a mixture of sperm, epididymal fluid, seminal vesicle fluid, prostate fluid, etc., the most important of which is sperm. The sperm travels from the husband’s reproductive tract, enters the deep vaginal fornix of the wife, arrives at the uterus through the cervix, reaches its destination, and begins a date with the egg, which blossoms successfully! The introduction of normal ejaculation is over, isn’t it interesting? But some people are not so lucky, they can not ejaculate or retrograde ejaculation, resulting in the inability to send sperm to travel normally, not to mention dating to the sister egg, what is going on? 1. failed sperm travel – no ejaculation! The first thing you need to do is to get a good idea of what you are getting into. The first thing you need to do is to take your wife to the hospital. This is where Xiao Ma is embarrassed to say that since getting married, Xiao Liu’s sex life is always without ejaculation. What disease does Xiao Liu have? Ejaculation disorder! It is a condition in which the penis can have normal erection and intercourse, but cannot ejaculate semen, or can ejaculate under other circumstances, but not in the vagina, and therefore cannot reach orgasm and obtain sexual pleasure. 2. wrong direction of sperm travel – retrograde ejaculation The above Xiao Liu is not ejaculation, there is a patient Xiao Li and his situation is similar, no semen out of the body, but have the feeling of ejaculation, he has retrograde ejaculation. Retrograde ejaculation is a disease in which there is normal penile erection, normal intercourse, and orgasm, and there are ejaculatory movements and sensations, but no semen is discharged from the urethra, and retrograde ejaculation to the bladder. It is clinically seen that sperm and fructose will appear in urine test after ejaculatory intercourse. 3. loss of control of sperm travel – premature ejaculation The first two cases do not have sperm discharge, while premature ejaculation on the sperm discharge, does not affect the sperm dating eggs, but affect the sexual experience, such people do not have the ability to extend or control ejaculation, by the wife, girlfriend scolded there is no —— said so much, understand male ejaculation The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things! The actual fact is that you can find a lot of people who are not able to get a good deal on this!
