Dorsal penile neurectomy, also known as selective dorsal penile neurectomy, is a procedure that is still controversial. The principle of the procedure is as follows: The penile sensory pathway starts from the sensory apparatus in the penile skin, penile head, urethra and penile corpus cavernosum, and sends out nerve fibers to fuse to form the dorsal penile nerve bundle, which joins other nerve fibers to become the internal pubic nerve, and then ascends to the spinal cord via the dorsal root of the sacral nerve, and the receptors are activated to transmit pain, temperature and tactile information through the dorsal penile nerve, pubic nerve, spinal cord and spinal thalamus bundle to hypothalamus and cortical layer for perception. 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. Selective dorsal penile neurectomy is a treatment for premature ejaculation by cutting off part of the dorsal penile nerve that conducts nerve impulses to reduce the sensitivity of the penis and glans, raise the ejaculatory stimulation threshold, and prolong the ejaculatory latency. The surgery was not introduced for a long time, foreign doctors began to try the surgery 10 years ago, but only 5 years ago in China, only a handful of large hospitals in China can do it, the doctor who can skillfully operate this surgery is very few, patients should choose a doctor with experience and risk, the efficacy is guaranteed. However, dorsal penile nerve amputation is a controversial surgical procedure. Some doctors and scholars advocate this surgical treatment for patients with severe glans sensitivity leading to premature ejaculation and for whom conventional non-surgical treatment is ineffective. However, most doctors do not advocate the use of dorsal penile neurectomy to treat premature ejaculation. The effect of dorsal penile neurectomy in the treatment of premature ejaculation is not exact, and many patients do not have significant improvement in premature ejaculation after the operation. 2, dorsal penile neurectomy is likely to cause intractable complications such as glans numbness, lack of sexual pleasure and penile erectile dysfunction (impotence). More seriously, nerve damage is non-regenerable, and it is easy to cut the nerve, while it is almost impossible to restore the cut nerve. 3, the root cause of premature ejaculation is the poor ability of the brain to control ejaculation. Sensitivity of the penis and glans sensation is not the main cause of premature ejaculation. Most patients with premature ejaculation, through medication and sexual behavior training, can prolong intra-vaginal intercourse time and achieve the desired effect of treating premature ejaculation, there is no need for surgery. 4. The use of surface anesthetics such as lidocaine gel during sexual intercourse is inexpensive and can completely eliminate the factor of penile and glans sensation sensitivity, and there is no need for invasive neurectomy. Therefore, to treat premature ejaculation, do not easily do dorsal penile neurectomy. To see premature ejaculation and other male diseases, it is best to go to the urology department or male department of a regular tertiary hospital to avoid being deceived.
