The Inner Workings of the Little Blue Pill: Viagra

For some men it may not be enough to know that Viagra works. They want to know how this drug works, and it just so happens that learning the way this pill helps men “get it up” is quite intriguing.

The Mechanics of Viagra Simplified

Viagra is swallowed and then it takes between 30 to 60 minutes for it to absolve into the bloodstream. From here it is distributed throughout the body in order to improve circulation.

This improved circulation is what helps a man get an erection. As the sildenafil citrate substance of this medication reaches the penis, an amazing action takes place.

The enzyme PDE5 is then inhibited, in order to prevent an erect penis from flattening (becoming flaccid). If flaccidity of a penis is prevented, a man’s member stays hard for longer times.

However, you have to understand that all this only usually happens if a man is stimulated. Viagra works if a man is “turned on” somehow to sex, usually by touch but it could be a voice or sound that is sexual or sensual that causes stimulation which leads to arousal.

When a man is sexually stimulated, cyclic guanosine monophosphate (cGMP) is produced. This substance relaxes blood vessel and artery muscles, which leads to more room for blood flow into the erectile chambers of the penis.

This all takes place until sexual arousal stops. Usually this is after a man has ejaculated and achieved orgasm, or after about four hours-which ever comes first.
