Dorsal penile nerve block is a method of treating premature ejaculation, but before this procedure, relevant tests must be performed to determine that over-sensitive glans nerve transmission is the main cause of premature ejaculation: the tests are 1. penile glans sensitivity check; 2. drug test (after the glans penis is coated with anesthetic cream to reduce glans sensitivity, sexual life is tested, and if the symptoms can be improved and the sexual life time is significantly prolonged, it is positive). If it is suggested that the dorsal penile nerve is too sensitive and the drug test is positive, it is suitable for dorsal penile nerve block treatment and may have a better result after the operation. And even for premature ejaculation caused by high glans sensitivity line, external anesthetic or condom intercourse can completely reduce the sensitivity of glans and achieve the purpose of treating premature ejaculation. The same applies to this treatment, not to mention the indications are very strict, as some private male hospitals advertise that they can “get rid of the disease”. This is why international guidelines for premature ejaculation recommend caution and do not recommend surgical treatment.
