Learning about Viagra An international study of middle-aged and older men shows that erectile dysfunction (ED) becomes more common as men age, no matter where they live. Up to 82% of men experience improved erections with VIAGRA. That means more than 4 out of every 5 couples who try VIAGRA benefit from it. VIAGRA improves erections in most men regardless of how long they have had ED, what caused it, or how old they are. And the effectiveness of VIAGRA has been proven in clinical studies of thousands of patients. |
