It causes a reduction in blood flow to the heart, brain and extremities, and can lead to heart attacks and strokes. Because it can also reduce blood flow to the penis, arteriosclerosis can lead to impotence. It accounts for most cases of impotence in men over 60 years of age. When veins in the penis cannot hold blood to maintain an erection, venous leak occurs. This is another cause of impotence.
Venous leak can be a result of injury, disease, or damage to the veins in the penis.
Other nerve disorders, such as multiple sclerosis, Parkinson's disease and Alzheimer's disease may also result in impotence. Medication There are over 200 prescription drugs that may directly cause or contribute to impotence. Among these are drugs for high blood pressure, heart medications, antidepressants, tranquilizers and sedatives. Remember, even if you suspect drug-related impotence, do not discontinue taking prescription medication without first consulting your physician. Chronic use of non-prescription recreactional drugs such as alcohol, as well as use of illegal drugs, can also cause impotence.
