How to regulate the ejaculation center

Ejaculation center - In the process of ejaculation, the corpus cavernosum is involved in the erection mechanism, while the urethra and corpus cavernosum are related to semen discharge and orgasm. During the male sexual acknowledgment period, the erect penis elongates the urethra, straightens the originally bent pipe, and the transverse diameter of the urethra can exceed twice its original size. The bulb of the urethra stretches a cavity that is three times larger than during the quiet period, and the urethral orifice opens with stimulation.

During sexual intercourse, the sympathetic nerves release a large amount of norepinephrine, which speeds up the transport of sperm from the epididymis to the vas deferens. The vas deferens and the ejaculatory duct are the channels for transporting sperm, and the vas deferens is also the treasure house of sperm that has been awakened. Under the action of norepinephrine released by sympathetic nerves, the epididymis, vas deferens, and ejaculatory ducts shrink in a coordinated manner one after another, not to mention the rhythmic strong contraction, driving semen into the posterior urethra. The vas deferens fluid can be directly injected into the posterior urethra without entering the seminal vesicle.

Under the control and control of sympathetic nerves, the smooth muscles of the seminal vesicles shrink peristally and discharge their secretions into the posterior urethra. Sympathetic nerve gratitude can shrink the smooth muscle of the prostate, excrete prostatic fluid, shrink the bladder sphincter, discharge semen into the urethra, and seal the bladder neck refractionally. It also prohibits the reverse entry of semen into the bladder and the prohibition of urine entering the urethra. Now, with the cooperation of the large segment muscles of the perineum, the semen is radiated out of the body through the urethra. At the same time, the bulb of the urethra is accompanied by rhythmic narrowing, resulting in a euphoric aftertaste. It started with 2 to 3 particularly violent contractions, followed by several weak contractions. The degree of sexual pleasure and orgasm varies depending on the soul pattern and the intensity and timing of sexual gratitude.
