A man will get an erection when sexually aroused either physically or mentally due to an intricate series of chemical reactions which result in an increased blood flow to the penis. The arteries and blood vessels leading to the penis become dilated allowing an increased blood flow to the corpa cavernosa, the two fleshy structures running along the length of the shaft of the penis. The corpa cavernosa then become engorged with blood, stiffening and swelling, making the penis erect.
Erectile Dysfunction Medicine Without a Prescription
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.
The ease with which men can order Viagra prescription medication has meant that it has become an easily treatable and manageable condition. Now that men can order Viagra online it is even simpler for sufferers of erectile dysfunction to pursue active happy sex lives.
