If it is diagnosed that there is a low threshold of nerve function, which causes premature ejaculation produced by local hypersensitivity of the glans, then the recommended treatment methods: a. The use of drug topical treatment, such as commonly used time-delay ointment, more than containing the ingredients of lidocaine or bupivacaine, applied externally to the glans, can reduce the sensitivity of the surface, play the role of surface anesthesia to achieve the purpose of prolonging sex life. However, because of the use of surface anesthetics and resulting in reduced local sensation, it may cause inadequate erection or cause the penis to fail to erect during sexual intercourse. And each time it is used, the duration is relatively short. Second, the dorsal nerve of the penis can be treated with surgery to cut off the fibers of the redundant dorsal penile nerve and retain 3-4 trunks to achieve a reduction in local sensitivity in the future, but not a complete loss of glans sensation. However, the surgery has certain risks, which may lead to bleeding, infection or glans necrosis, foreskin necrosis, or complete loss of sensation and other risks.
