When a man is sexually aroused a series of reactions occurring at a molecular level in the brain and the bloodstream result in the dilation of the penile arteries and blood vessels. This increases the flow of blood to the fleshy tissue running the length of the penis, known as the corpa cavernosa. The corpa cavernosa then become engorged with blood, which swells and stiffens the penis into an erection.

Erectile dysfunction occurs due to an insufficient flow of blood to the penis when arousal occurs, this can be due to health problems such as high blood pressure or high cholesterol. The blood flow is restricted due to the constriction of the blood vessels by a natural enzyme of the body called phosphodiesterase type 5, or PDE5. The PDE5 enzyme acts as a vasoconstrictor, which contracts the cells lining blood vessels.
Viagra’s main active ingredient is sildenafil citrate which, like other forms of erectile dysfunction treatment, is a PDE5 inhibitor that restricts the action of the PDE5 enzyme on the cells of the blood vessels. The blood vessels can then increase the blood flow to the corpa cavernosa and produce an erection. Viagra should be taken around thirty minutes prior to intercourse and the erection produced can last from between two to four hours.
