Physical causes: About 8 in 10 cases of ED are due to a physical cause. In most cases due to physical causes (apart from injury or after surgery) the ED tends to develop slowly. So, you may have intermittent or partial ED for a while, which may gradually get worse. If the ED is due to a physical cause, you are likely still to have a normal sex drive (libido) apart from if the cause is due to a hormone problem. In some cases, ED causes poor self-esteem, anxiety, and even depression. These reactions to ED can make the problem worse. Canadian pharmacy cialis pfizer best online pharmacy for levitra

Some studies suggest that men who have made lifestyle improvements experience increased rates of success with oral medications. A few causes of impotence may be iatrogenic (medically caused). How does an erection normally occur? The neurotransmitters which are released in the penis cause another chemical to be made called cyclic guanosine monophosphate (cGMP). An increase of cGMP causes the arteries in the penis to dilate (widen). This allows extra blood to flood into the penis. The rapid inflow of blood causes the penis to swell into an erection. The swollen inner part of the penis also presses on the veins nearer to the skin surface of the penis. These veins normally drain the penis of blood. So, the flow of blood out of the penis is also restricted, which enhances the erection.
