There are a lot of men, especially the elderly ones, who have a problem with erection. Not only is this a personal issue, but it can actually affect relationships too for obvious reasons. Sexual intercourse is a vital part of any intimate relationship, especially for married people. It is a good thing that there is a drug that can be used in treating erectile dysfunctions- Viagra.

Viagra, medically referred to as Sildenafil Citrate, can also treat pulmonary arterial hypertension. It was discovered and developed by British medical scientists and then the Pharmaceutical giant Pfizer made it very big in the United States.

How does Viagra work?

Viagra works by inhibiting the body’s cGMP-specific phosphodiesterase type 5. This is an enzyme that can delay cGMP’s degradation that is responsible in regulating the penis’ blood flow. In essence, it can build up cGMP , thus, enlarge the penis size. The larger the amount of cGMP in the penis, the greater is the amount of blood that flows, which leads to erection.

Notice that when a man is sexually aroused, his arteries in the penis tend to widen and relax. As such, more blood can flow to the penis which causes it to become erect and harden. When taking Viagra, the veins that are responsible for carrying blood away from the penis are suppressed. Less blood is flowing out of the penis and more blood coming in, which results in erection.
