A Bit of Viagra History
The drug – Viagra appeared about 15 years ago. The German company conducted a study of drugs for the treatment of cardiovascular diseases. One of the side effects of the drug was the appearance of an erection in the presence of sexual excitement. Viagra appeared in the course of its further development. Since then, Viagra has saved many families, brought pleasure to many women and men.
What does Viagra Do?
When there is sexual excitement, an erection appears. That is, Viagra is produced to increase the blood flow into the penis to achieve and maintain the erection.
If a man took Viagra he should be sexually excited to achieve an erection: caresses, hugs, kisses. Then, under the influence of Viagra, an erection appears, which is supported and kept by this ED drug throughout intercourse. When sexual intercourse is completed, the excitement disappears, and the drug loses its effect. The effect of Viagra persists for 5 hours but there are cases when the effect lasts for a greater period of time. More details about how long does viagra last are given here.
Viagra: Effective or Not?
Since sexual excitement depends on the level of testosterone, Viagra is less effective in people with a low level of the male sex hormone.
The drug acts weakly on men having certain diseases, for example, diseases of the inner blood vessels’ lining (endothelium). If it produces not enough substance, which is a mediator of erection, then Viagra effect is insignificant. This is observed in patients with diabetes or metabolic syndrome. This erectile dysfunction drug is contraindicated in women. Viagra is ineffective in people with severe atherosclerosis. Having such diagnosis, the vessels cannot expand but an erection is an expansion of the penile arteries.

Sexual intercourse is a kind of stress for the body because of the load on the cardiovascular, respiratory, muscular, central nervous systems. If a person cannot endure these loads, then Viagra won’t be safe. Inform your doctor before starting Viagra about the diagnosis you have in the medical history.
