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.
