Mr. Wang in recent years due to excessive work pressure, physical fitness significantly decreased, conjugal life is also more and more incompetent, time is getting shorter and shorter, very distressed. Because of gullible advertising, said the penile dorsal nerve selective excision can be completely cured, Mr. Wang was moved. After the surgery, the short duration of conjugal life not only did not improve, but also the erectile function decreased significantly. Mr. Wang therefore regretted it and was in pain. The first thing you need to do is to consider cutting off a few nerves on the penis to reduce sensitivity, because the time of conjugal life is less than 2 minutes, the wife’s satisfaction rate with the husband is less than 50%, and the training is still not adjustable. The cause of primary premature ejaculation is still unclear. Current research has found that patients with primary premature ejaculation not only have psychosomatic abnormalities, but also have organic lesions, i.e. high excitability of the dorsal sensory nerve of the penis, short ejaculatory latency and low ejaculatory stimulation threshold, so that premature ejaculation is easily induced during sexual intercourse. Selective dorsal penile nerve branchotomy reduces penile excitability and thus prolongs intravaginal ejaculation latency, thus achieving the goal of treating premature ejaculation. A total of three main nerves in the median and both sides are preserved, and the rest are all cut off, so that surgical complications can be avoided while achieving surgical results. The efficacy of dorsal penile nerve amputation is related to the number of nerve branches cut during the operation. Too many branches of the dorsal penile nerve will increase the risk of complications such as penile numbness and erectile dysfunction; too few will not achieve the surgical treatment effect. Dr. Chen introduced that normally the branches of the dorsal penile nerve should be two, but patients with primary recalcitrant premature ejaculation have as many as 8-9, individuals even 13, too many too dense nerve distribution in the glans coronal groove, resulting in a high sensitivity to sexual stimulation, once entering the vagina or even just touching the vaginal opening will appear a touch, a ejaculation like a note, that is “severe premature ejaculation”. . The penile sensory pathway starts from the sensory apparatus in the skin of the penis, the head of the penis, the urethra and the corpus cavernosum of the penis, and sends out nerve fibers that fuse to form the dorsal penile nerve bundle, joining other nerve fibers to become the intrapubic nerve, which then ascends to the spinal cord via the dorsal root of the sacral nerve, and after the receptors are activated, pain, temperature and tactile information is transmitted to the hypothalamus and the cortical layer through the dorsal penile nerve, the pubic nerve, the spinal cord and the spinal thalamic bundle for sensation. With contact stimulation, nerve impulses from the penile skin and the penile head are transmitted through the dorsal penile nerve to initiate and maintain a reflex penile erection. Therefore, after performing penile sensitive nerve block, the sensitivity of the penile head can be reduced, the ejaculatory stimulation threshold can be increased, the ejaculatory latency can be prolonged, and the quality of sexual life of patients can be improved. But now, the scope of application of dorsal penile nerve selective excision has been arbitrarily expanded. Originally, this surgery can benefit some male patients and give them a harmonious family, but after many people cut, not to say goodbye to premature ejaculation, but to say goodbye to the “man” completely. The patient’s condition is compounded by the fact that the economy, body and mind are suffering a serious blow. The last thing you need to do is to be cautious about the selective excision of the dorsal nerve of the penis. And I hope that you prefer a combination of Chinese and Western medicine treatment.
