In 33 patients with erectile dysfunction arterial inflow was measured by Doppler-sonography over the superficial dorsal and deep cavernous arteries in the proximal section after local application of 1.6 mg glycerol trinitrate (nitroglycerin) to the glans penis. With this test we were able to reveal a minimal increases in maximal systolic flow over both arteries at 29/66 measurement sites. This is thus an easier way of localizing penile vessels in the flaccid state. In no case did we see tumescence or rigidity.
