The corpa cavernosa then become engorged with blood, stiffening and swelling, making the penis erect.
Erectile Dysfunction affects One in Ten Men
Erectile dysfunction occurs when there is an inadequate supply of blood to the penis during arousal or sexual activity. The blood supply is restricted by the contraction of the penile arteries and blood vessels. This is caused by a naturally occurring vasoconstrictor of the body, called phosphodiesterase type 5, more commonly referred to as PDE5. The PDE5 enzyme causes the contraction of the cells lining the arteries and blood vessels, thus restricting the blood supply to the penis.
Viagra is a PDE5 inhibitor which renders the enzyme inert. The blood vessels are then free to dilate and increase the blood flow to the corpa cavernosa, giving the man an erection. Viagra will only be effective if the man is in a state of sexual arousal as PDE5 will only be present at this time.
