    TLDR Minoxidil works better than nitroglycerin for treating impotence with fewer side effects.
    A study conducted 31 years ago compared the effectiveness of topically applied minoxidil, nitroglycerin, and a placebo in facilitating erections in patients with organic impotence. The study found that minoxidil was more effective than nitroglycerin and placebo in increasing diameter, rigidity, and arterial flow of the penis. The highest activity was found in neurogenically impotent patients, and fewer side effects were found with minoxidil than with nitroglycerin. The study proposes minoxidil as a long-term therapeutic agent for organic impotence.
