Viagra is a small blue pill that is taken orally when one wants to have sex. It helps men to get erection consistently and keep it when they become stimulated sexually.
How Viagra Works Viagra enables men with erectile dysfunction to have response to sexual stimulation. Generally, Viagra increases blood flow to a man's penis, so that when he is sexually excited, he can be able to consistently get erection and keep it. Whenever a man has a sexual excitement, the arteries located in his penis relax and widen thereby allowing more flow of blood into his penis. The increased flow of blood results to a harder and erect penis. This happens because there is compression in the veins that carry away blood from the penis and therefore there is restriction in the flow of the blood out of the penis. Since there is more flow of blood in the penis and less flow out, the penis enlarges, which results to an erection. At times, blood vessels or nerves that are part of this process fail to function properly and when this happen a man may not get erection and keep it. When he is through with sex, the erection will definitely go away. This medication can treat psychologically based erectile dysfunction in men with vascular diseases. Those suffering from hypertension, depression, ischemic heart disease, diabetes and in men whose prostates are removed.
