ED 101

Erectile dysfunction can be an utterly confusing condition for a man when he first encounters the symptoms. Everything else in the body will seem to be working fine, but the lack of an erection when there is sexual stimulation should give a hint to the man that there is something amiss. While many people rush to a local doctor or online pharmacy to Buy Generic Viagra as a way of curing the problem, it is a better idea for the man to first learn about erectile dysfunction, or ED, to know exactly how it affects the body and how a medication like generic Viagra fights this problem.

In a man who has no issues with ED, there are a few enzymes that control how his body reacts to sexual stimuli. When a man is mentally aroused, brain signals are sent to these enzymes and blood is allowed to enter the penis where it helps to make an erection. On the other hand, this action does not happen in a man with ED because the enzymes are no longer in balance. Specifically, it is the PDE5 enzyme that is overproduced and is causing the problem. While the brain signal reaches many of the enzymes, there are still PDE5 enzymes that have not received the instruction to let blood go to the penis. This means that an erection is actively blocked, but Viagra Online helps to correct the issue.

When a man with ED takes his first dose of generic Viagra, the ingredients of the drug are absorbed into the blood and travel to the penile muscles where the PDE5 is located. With a specific mechanism of action, the ingredients become bound to the PDE5, thus letting the brain signals once again translate into the presence of a physical erection if there is mental arousal.
