What is erectile dysfunction?

This is one of the problems caught under the general heading of impotence. It describes a man who is unable to get an erection at all or who gets an erection but then loses it before sexual intercourse is complete.

What causes it?

Erectile dysfunction (ED) can be a symptom of a more serious underlying health problem and, as a result of medical guidelines, all doctors now treat men with ED as heart patients until this possibility is excluded. The causes range from an accident leaving physical damage to the penis itself or the back, surgery in the groin area, e.g. to remove prostate cancer, to major depressive disorders which can result in a loss of libido. Depending on your medical history, there can be a number of tests involved to give you a comprehensive diagnosis and peace of mind when the more serious disorders and diseases are eliminated. When booking an appointment with your doctor, always make sure you allow enough time for a thorough examination.

How does levitra work?

Forming an erection is simple plumbing. Your body opens a value to let a lot more blood into the penis. As this blood is absorbed by the sponge-like tissue, the swelling pinches the veins that should drain the blood out. This forces the penis to inflate as an increasing amount of blood is pumped in. This process depends on the muscles getting the right signals at the right time to open and close the value letting the blood in. Levitra prevents the premature release of phosphodiesterase type 5 (PDE5) which shuts down the valve. This allows the erection to form and remain until sexual activity is completed. Obviously, the medical explanation is more complicated with different groups of muscles being required to dilate to contract, but the principle is the same.
