Viagra is a PDE5 inhibitor. PDE5 can prevent your penile arteries from dilating. Because Viagra stops the production of PDE5, your arteries dilate and blood flows into your penis to cause the erection. The major advantage of this approach is that, without PDE5 in your blood stream, you respond naturally to sexual stimulation with an erection. Unlike the injection of an artificial chemical into the penis, Viagra does not itself cause the erection. All Viagra does is to remove an obstacle to the natural cause and effect. Once sexual intercourse has finished, your penis returns to its usual flaccid state until you are ready to go again.
