Viagra work in physiological

Having added information on how an erection is simulated in the body is important. This will be very helpful in your comprehension of how Viagra works. When a man is sexually stimulated the following things tend to happen in the human body.

1. An impulse from the brain is sent to the penis. This impulse tells the penis to relax which in turn causes a reaction to the arteries.

2. This reaction makes the arteries to open up which allows blood to flow in the penile area.

3. When the blood flows in the penile area the arteries thicken and harden.

4. The veins carrying blood out of this constricts the penile area and the flow of blood out of the penis is restricted.

5. The above action of letting less more blood in and less blood out causes the penis to remain erect during sexual activity.

6. For men with erection difficulty, the nerves or blood vessels in the penis do not work properly and an erection is prevented. This is where Viagra comes in. It increases the blood flow to the penis. As such, when a man is sexually excited, he can get and keep an erection fit for having sex.

The time taken for Viagra to work in most men is about fourteen minutes. This information is made available after an extensive study on 228 males who have been successful with Viagra before. Viagra should be taken at least two hours of anticipated sexual activity. The reaction of the drug usually starts within thirty minutes and lasts for about four hours, which is more than enough for a good sexual experience.

Most part of our bodies moves on the principle of moving muscles to do a particular function. The penis however works on a different principle altogether; the penis has no muscles. So then one may wonder how does an erection occur if it does not have any muscles. As it is the common perception of most people that you need to have your muscles doing their proper function for the simplest of movements such as sticking your tongue out.

The penis works on blood pressure; yes when the penis is limp it has very little blood flowing in and is diverted by veins, which run out of the penile area. A good way of thinking of how the penis operates is to take the example of a balloon. No air and the balloon will remain limp but when inflated with air it is fully blown up.

The penis also works on the same principal when you are sexually stimulated your brains sends an impulse. This then starts the five step process that we have mentioned on top.
