Effect of oral administration of high‐dose nitric oxide donor l‐arginine in men with organic erectile dysfunction: results of a double‐blind, randomized, placebo‐controlled study

Abstract

Oral administration of L-arginine in high doses seems to cause significant subjective improvement in sexual function in men with organic ED only if they have decreased NOx excretion or production. The haemodynamics of the corpus cavernosum were not affected by oral L-arginine at the dosage used.
