Treatment With Peripheral Nerve Stimulation of the Pudendal Nerve in Patients With Erectile Dysfunction

Erectile dysfunction is known as any alteration that produces a modification in the erectile response, whether of organic, psychogenic or relational cause. In this case the pudendal nerve is addressed, since it has its origin in the sacral plexus, deriving from the S2, S3 and S4 nerve branches. Its fibers have different innervation, being the pudendal nerve a mixed nerve, and estimating that it has 30% of autonomic innervation, and 70% of somatic innervation (50% sensory and 20% motor). Peripheral percutaneous nerve stimulation (proposed treatment) is performed with a needle to stimulate the peripheral nerves in such a way as to stimulate most of the area of the structure, stimulating sensory and motor nerve endings of the deeper tissues.
