Viagra and Working :
The name recognition of Viagra® is so good that nearly every adult in America has heard of the drug and can tell you what it does.
What Viagra® does is simple: When it works as intended, Viagra® causes a man who is sexually stimulated to get an erection.
How does Viagra® do that? And why does Viagra® work only if the man is sexually stimulated? For that matter, what causes an erection in the first place? In this article, we'll answer all of those questions and more...
For many people, talking about the penis is tough. This area of the body is considered private and is usually not discussed publicly. However, the penis is simply a part of the male anatomy designed to accomplish a task
the case of the penis, there are actually two tasks that it handles:
releasing urine from the bladder, known as urination
releasing sperm and seminal fluid from the prostate gland, known as ejaculation
Viagra® helps with the second task: ejaculation.
When things are working properly, ejaculation is a three-step process:
The man becomes sexually aroused.
The penis responds by becoming erect.
Stimulation of the penis causes ejaculation.
That sounds simple enough, but in many cases, step two does not happen, making step three difficult or impossible. Although the man is stimulated, the penis does not become erect. To understand why, you need to understand the technology of an erection...
When you want to move nearly any part of your body, you do it using muscles. Whether you are moving your fingers, toes, arms or legs, muscles do the work. Even when you stick your tongue out, you do it using muscles:
You think about moving some part of your body
The appropriate muscles contract
That part of the body moves
Muscles let you move your body voluntarily with precise control.
The penis, on the other hand, is completely different. There are no muscle contractions involved in making the penis erect. To become erect, the penis instead uses pressure.
Opening things up :
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.
If you are running in a marathon, your body needs to send more blood to your arm and leg muscles, and it may want to cut most of the blood flowing to the stomach (and other non-essential organs) in order to save oxygen for the legs.
