There are several types of erectile dysfunction or male impotence. The first is arteriogenic in which the arteries which supply blood to the penis do not have enough blood to cause an erection. This is a more common occurrence when there is narrowing of the arteries from a disease such as diabetes or in the elderly. Individuals who have high blood pressure or have had an injury in the genital region can also have a blockage in the artery that supplies the penis. An injury is more commonly found in young men. These can happen following eight fracture of the pelvis or in cyclists who sustain friction in that region which can cause a thrombus to develop in the artery.
Impotence resulting from injuries are actually very common but often unsuspected. Patients who have sustained an orthopedic or urologic injury may find that after the fractures have healed they are impotent. Fortunately if they are evaluated by an andrologist who takes the complete history the causative agent may be discovered.
