The nerves to the prostate come from the pelvic plexus, including sympathetic and parasympathetic nerves. Sympathetic nerve excitation, so that the prostate, seminal vesicles and ejaculatory ducts smooth muscle contraction, prompting semen discharge, while the sympathetic nerve so that the internal urethral sphincter and prostatic sphincter contraction, but inhibit the contraction of the forced urethral muscle, so that the bladder neck and the prostate part of the urethra closure, thus preventing the urine discharge, and preventing the reflux of semen in the ejaculation of semen. Parasympathetic nerves mainly stimulate the secretion of prostatic follicles, which produce prostatic fluid and participate in the composition of semen. When the parasympathetic nerves are excited, the urethral muscle contracts and the urethral sphincter and prostatic sphincter are dilated to promote urination. The sympathetic and parasympathetic nerves belong to the vegetative nerves, if there is a vegetative nerve disorder, sympathetic nerve over-excitement may appear difficult to urinate, parasympathetic nerve over-excitement occurs to force urination, and this is most likely to be the case is that the ultrasound examination of the size of the prostate gland is not very large, that is to say, it is not the prostate enlargement affects the urination, then where is the problem? The most likely problem is two areas, one is the prostate contractile function, and the other is the bladder contractile function. And both of these areas are innervated by sympathetic and parasympathetic nerves. What is the principle of acupuncture for prostate? Since the neurovascular bundle controlling the prostate and bladder is from the pelvic plexus all the way down, extending the outer wall of the rectum down through the prostate and bladder, and finally to the dorsal plexus nerves in the sponge body. Therefore, using acupuncture needles with electricity and accurately stabbing the needles into the neurovascular plexus near the bladder and rectum to stimulate bladder contraction and the neurovascular plexus of the outer wall of the rectum, which leads to blood supply and nerve nutrition to the prostate gland and also regulates the disorders of the vegetative nerves. This in turn improves urinary function.
