Viagra is treatment for erectile dysfunction, when the brain sends signals to "member" to become erect, but it can't do so.
The brain sends the message to the "member" in the form of NO. There is a natural catalyst of NO found near the "member," which cuts down the amount of NO. Normally, there is still enough NO to cause an erection, but not in all cases.
So...Viagra blocks the catalyst from cutting down the amount of NO, thus leaving enough NO to cause an erection.

How can you give a man an erection with a pill? You can't give a man a pill loaded up with a general smooth-muscle relaxer like phentolamine -- that would cause all of the smooth muscle throughout the man's body to relax, and that might create a lot of problems. What you need is a drug that acts only on the smooth muscle in the arteries of the penis.
To understand how to make a penis-specific drug, think about the way blood flows in your body. Your body has just one pump -- the heart. But different parts of the body need different amounts of blood at different times.
For example:
* If you eat a big meal, your body needs to send more blood to the stomach and intestines to help with digestion.

It releases NO which is a metabolite good for erection since the blood is retained in the penis
