WHO definition of premature ejaculation: 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 before reaching a full erection for sexual intercourse, the difficulty is not caused by a prolonged lack of sexual intercourse. Sensory hypersensitivity/hyperexcitability of sensory nerves in the penis is one of the causes of premature ejaculation, and the treatment of premature ejaculation may be achieved by surgically selecting to cut off part of the sensory nerves so that nerve impulse afferents are reduced. This is the theoretical basis of dorsal penile neurectomy. However, the effectiveness and safety of the procedure have not been confirmed by the industry. The effectiveness rate in foreign literature is less than 50%; domestic clinical studies conclude that the efficacy is very inaccurate and the technique itself is not perfect, at most, it can be used as a scientific research study with full consideration of patients’ wishes and definitely not for clinical promotion. In addition to common complications such as infection and bleeding, dorsal penile neurectomy is associated with more serious complications such as penile numbness and erectile dysfunction. However, this procedure, which is almost rejected in the professional field, has been greatly exploited by some private male hospitals and carried out in full swing, causing lifelong regrets to some patients.
