Acting as a second messenger molecule, cGMP regulates the activity of calcium channels as well as intracellular erectipe proteins that affect the relaxation of corpus cavernosum smooth muscle. Estimates of the prevalence of chronic ED in the United States have varied, partly because of differences in methodology and populations in epidemiologic studies. This is likely because most of the L-arginine that is ingested is metabolized or broken down before it gets a chance to reach the bloodstream, whereas L-citrulline is not Please review our Terms and Conditions of Use and check box below to share full-text version of article.
