How does viagra work

Viagra

To understand how viagra works. First, you need to understand the process of how a man gets an erection. When a man gets sexually aroused the nervous system in the erectile tissue of your penis releases nitric oxide (NO) 

Man getting erections may seem pretty basic but they’re more complicated. Getting an erection involves annexation between your heart, blood vessels, hormones, nerves, and even your mood. 

During a man getting a get an erection cGMP (cyclic guanosine monophosphate) causes tissues in the penis to relax. the result of that blood flows into the penis and is trapped—up to eight times more blood than when the penis is flaccid. After some time this trapped blood gets released, the erection subsides, and blood flow returns to normal.

PDE-5(Phosphodiesterase type 5) is an enzyme that breaks down a molecule called cGMP, resulting in vasoconstriction or the narrowing of blood vessels.

Some time high levels of PDE-5 are found in the penis, lungs, and retina. PDE-5 is also found throughout the body within the smooth muscle cells of blood vessels and muscles. 

Viagra works for men by blocking PDE-5. When PDE-5 is blocked, cGMP does not get broken down. As a result of that, the tissues in the penis stay relaxed and engorged with blood.

If a man does not turn on, man’s brain will not stimulate the release of any nitric oxide and a man will not produce any cGMP.

ED (Erectile dysfunction) is when a man experiences issues getting an erection. Or keeping it long enough for sex. It’s also known as ED or impotence. It happens when insufficient blood streams to the penis, preventing an erection.

It’s been proven to help men with all degrees of ED. but remember one thing takes only when you need it.
