Do you want to know about how Viagra works. Through below steps you can learn about blood flow within the body and how it relates to the smooth muscle of the penis.

1. The brain sends signals to NANC cells in the artery.
2. The NANC cells release nitric oxide (NO). Nitric oxide acts as a molecule and stimulates an enzyme called guanylate cyclase
3. The guanylate cyclase converts a chemical called GTP into another chemical called cGMP
4. cGMP relaxes and increases blood flow.
5. Meanwhile, PDE is decomposing the cGMP and turning it back into GTP
6. There is a cycle - guanylate cyclase turns GTP into cGMP, and PDE turns cGMP into GTP. Nitric oxide turns the cycle on.

The Role of Viagra and how it increases the pleasure of erection
1. Increase the amount of nitric oxide produced in the penis
2. Increase the amount of cGMP produced in the penis in response to the nitric oxide
3. Eliminate the PDE in the penis so that the cGMP builds up instead of getting decomposed by the PDE

When a man suffers from erectile dysfunction there could be many reasons behind it. But one of the most common reason found in older men is that their arteries in the penis aren't dilating enough when the brain sends the signal. The man is aroused and the nerves in the penis are producing nitric oxide, but the amount of cGMP produced isn't enough to maintain an erection. The way that Viagra goes about solving this problem is quite ingenious.

Viagra is one of the most popular drugs sold online. The drug aces every other successful pharmacy’s record of top-sellers. With erectile dysfunction becoming a major, embarrassing problem for men, the availability of ED treatment drugs like Viagra makes impossible things possible – men get a new leash of sexual life, thanks to the availability of the blue pill. However, Viagra is not something that can be chewed or consumed like other harmless pill. People have lot of notions about the drug, which bring us to the risks and benefits involved in buying Viagra online.
