Dosage is carefully balanced to produce an erection that lasts about two hours, and patients learn how to inject themselves. Urologists recommend that drug use be limited...

-- When arteries to the penis have become constricted, surgery can sometimes restore blood flow. In one operation, called an endarterectomy, the blood vessel is opened and scraped clean. Doctors also bypass blockages by grafting sections of an abdominal artery around narrowed branches of the iliac artery that lead to the...
A third technique being used to clear blood vessels is balloon angioplasty, in which a tiny collapsed balloon is threaded into a blocked passage and inflated. Atherosclerotic plaque is crushed against the artery walls, widening the blood pathway. Yet another delicate operation entails tying off penile veins that fail to...
