Abstract:
Objective To elucidate the neurological mechanism of the referred pains in pelvic floor associated with the prostate. Methods The rat prostate was electrically stimulated, then the elicited action potentials (AP) of the lumbar and sacral nerves and the compound muscle action potentials from the external sphincter muscle of anus were detected. Results Action potentials from the iliohypogastric, genitofemoral, lateral femoral cutaneous, femoral, sciatic nerves compound muscle action potentials (CMAP) from the anal external sphincter were recorded. Conclusion Electric stimulation of the prostate can induce action potentials of the lumbar and sacral efferent nerves through the spinal reflex, resulting in referred pains in the perineal and pelvic areas due to muscle contraction.
