How Viagra works
-A man takes a Viagra® pill.
-The sildenafil citrate enters his bloodstream and flows throughout his body.
-The sildenafil citrate attaches to the PDE5 enzyme in his penis and disables most of it.
-When the man becomes sexually aroused, the brain sends the normal message to the NANC cells in his penis, which produce nitric oxide as usual.
-The nitric oxide creates cGMP, which starts relaxing the arteries in his penis.
-Since the PDE5 has been disabled, the cGMP in the penis does not break down.
-Instead, it builds up and lets the arteries in the penis fully dilate.
-His penis inflates with blood, and the man gets a full erection.
