Q. Does Viagra effectively treat ED regardless of its cause? Or is it intended only for some forms of impotence?
A. Viagra and the other oral ED drugs that followed in its wake are all designed to treat ED that’s caused by insufficient blood flow to the penis, the largest single cause of impotence. If your ED has its origins in psychological causes or results from a congenital or traumatic injury to the arteries that supply blood to the pelvic region, your doctor can recommend alternative therapies.
It is possible that Viagra might have a placebo effect on men whose ED is not vascular in nature, but it probably won’t work over the long haul in such situations. Those who are suffering from ED that is psychological in origin would be better served through psychological counseling, while surgical intervention might be required to resolve injury to the arteries in the pelvic region.
