When your partner touches you sexually, your brain sends signals to your endothelial cells ordering them to secrete Nitric Oxide. This Nitric Oxide once released in the blood vessels of penis has the function of activating guanylyl cyclase. Guanylyl cyclase is an enzyme which performs the ritual of converting GTP into cGMP. cGMP dilates the blood vessels of the muscles of the love organ due to which blood seeps in the penile muscles. As the muscles get filled with blood, penis is erected. Those men who suffer from impotence are unable to develop sufficient level of cGMP in the vessels of their penis to cause dilation which would then result in filling of muscles of the penis Viagra improves impotence by increasing the quantity of cGMP in the blood vessels of penis. It should be noted that Viagra never increases the quantity of cGMP by increasing its synthesis instead it does so by protecting cGMP from the attack of phosphodiesterase(PDE), an enzyme which breaks down cGMP into GMP.
Viagra is commonly known by the nick name "blue pill" owing to the blue color of its tablets.
