The Science Behind the Wonders of Viagra
Viagra has been known to give men an erection or help them sustain one during sexual intercourse. But do you know how does do this particular job? Well, Viagra contains an essential ingredient Sildenafil Citrate that increases the blood flow to certain areas of the body, including the penis. The process of erection begins all the way up inside the brain. When a person is sexually stimulated, nerve signals are sent from the brain to the penis. However, when a person suffers from erectile dysfunction, the flow of blood gets deteriorated. This is due to the action of an enzyme known as Phosphodiesterase Type 5 (PDE 5). The enzyme PDE5 causes a constriction in the arteries and doesn’t allow blood flow properly. Sildenafil Citrate present in Viagra blocks the action of PDE 5 and relaxes the smooth muscles present in the walls of the blood vessels, including the penis. It enables the production of cGMP that is responsible for the contraction and dilation of blood vessels. When a person is sexually stimulated, nitric oxide is released into the penis. This allows cGMP to be produced properly and blood can easily flow to the penis. As more and more blood flows, a pressure is created. This leads to an erection. The effects of Viagra are known to last for a period of 4-5 hours. However, this may vary from one person to another depending upon factors such as age, metabolism, lifestyle, health conditions, etc. It is, therefore, essential to reach out to a medical professional who can determine the exact cause of the problem by performing diagnosis and running various tests. Let your doctor know about your medical history in detail so that he can provide the utmost treatment to you.
Meanwhile, if you don’t get the desired benefits of Viagra, there are other PDE 5 inhibitors that can help you.
