Updated application of penile electrophysiological examination in the diagnosis and treatment of male sexual dysfunction

Electrophysiological examination of penile nerves involves detection of somatic and autonomic nerves, including dorsal nerve somatosensory evoked potential, cavernous muscle reflex, skin sympathetic response, cavernous electromyography, and others, which plays an important role in the diagnosis of male sexual dysfunction, such as ED and premature ejaculation, as well as in the selection of treatment methods and evaluation of therapeutic effects. Due to the complex mechanisms of the brain, spinal cord and peripheral nerve pathways relating to erectile and ejaculatory centers in men and many unknown areas in penile electrophysiological techniques, penile electrophysiological examination has not been widely accepted by doctors and patients. Further studies are needed to provide more scientific and convincing evidence in this field.
