Sildenafil for Prostate Cancer

Sildenafil, which is trademarked as Viagra, is an oral drug which may improve the flow of blood to the penis when the flow of blood has been altered as a result of prostate cancer treatment. Sildenafil was originally developed as a drug that was hoped to improve blood flow to the heart. What researchers found was sildenafil was much more effective in improving blood flow to the penis. Sildenafil is a medical treatment known as a PDE-5 inhibitor used for sexual impotence that is caused biological factors. Most prostate cancer treatments commonly cause impotence as a side effect because some treatments shut off veins that lead into the penis. Sildenafil works by relaxing the smooth muscles in the penis and allowing more blood to flow in. Sildenafil is not an aphrodisiac and will not work as an potency enhancer without proper arousal. Men who have undergone prostate cancer treatment and who are anxious about engaging in sexual relations again may not benefit from sildenafil. Changes in biological function are not always responsible for impotence.
