When a man is sexually stimulated and aroused, a certain substance is released into erectile tissue called nitric oxide. This substance stimulates an enzyme that releases another substance called cyclic guanosine monophosphate, which in turn softens the cells of smooth muscle. This causes the blood vessels in the penis to dilate and as a result, blood flows to the penis more easily. Another effect of the medication is that the case of erectile tissue itself to fill with blood. As a result, awakens.
If a man is not sexually aroused, the brain will not provoke the release of nitric oxide and the body will not produce cyclic guanosine monophosphate.
