The most commonly used definitions are those of the American Psychiatric Association and the World Health Organization, with the former defining premature ejaculation as “persistent or periodic minimal stimulation prior to penetration. Ejaculation during or shortly after penetration and before the individual’s will, causing significant distress or affecting partner relationships.” The latter defines premature ejaculation as, “The inability to delay ejaculation with full enjoyment of lovemaking, as evidenced by one of the following: 1. Ejaculation before or soon after the onset of sexual intercourse (within 15 seconds); 2. Ejaculation occurring before reaching a full erection for sexual intercourse, where the difficulty is not due to a prolonged period of lack of sexual intercourse. Penile sensory hypersensitivity or excessive excitability of penile sensory nerves is one of the causes of premature ejaculation. Based on this theory, the treatment of premature ejaculation may be achieved by surgically cutting off part of the sensory nerves, causing a decrease in the sensitivity of the head of the penis and a decrease in the afferent nerve impulses, which prolongs the time it takes for the ejaculatory nerves to reach their thresholds of excitation. Surgical efficacy and safety has not been recognized by the industry, the domestic and foreign research results of this surgery, the limited domestic literature claimed to have as high as 90% effective rate, the foreign literature of the effective rate of less than 50%, and numerous complications. The operation even as a research operation, in China’s best conditions in the university hospital, there are the most stringent indications, surgical patients must also have the following conditions: 1, erectile function is normal; 2, married or have a fixed sexual partner, regular sex life of > 1 year; 3, severe premature ejaculation; 4, no other organic factors; 5, normal psychological quality; 6, the penis coated with local anesthetic effective; 7, wear Condom effective; 8, conventional sexual behavior therapy > 2 months is still ineffective; 9, the age of the general <40> 40 years old but a strong desire for surgery. After Harbin, Beijing, Shanghai and other megacities of the University Hospital clinical data summarized, the conclusion is: dorsal penile nerve block surgery efficacy is very inaccurate, the technology itself is not perfect, at most in full consideration of the patient’s wishes as a scientific research and absolutely can not be used for clinical promotion. In addition to the common complications of penile surgery such as infection, bleeding and incision splitting, dorsal penile nerve block is prone to more serious complications such as penile numbness and erectile dysfunction (ED) if too many branches of the dorsal penile nerve are cut. In general, partial severance of branches of the dorsal penile nerve does not affect erectile function, but it may result in penile numbness and a significant lack of sensation, which can diminish the function of penile reflex erection and affect erectile function. Elderly men are themselves prone to ED, and this procedure should never be used in the elderly or in patients with premature ejaculation in combination with ED. Dorsal penile nerve block is not mentioned in any urology textbooks. This procedure, which is almost denied in the industry, is widely used by private male hospitals and has become one of the main means of enrichment for private male hospitals, and patients with serious complications such as penile numbness and erectile dysfunction (ED) abound after the procedure.
