When your eyes watch any sexualy provoking scene or brain thinks of any sexual thought, signals are sent from the brain to the penis triggering erection. Signals from the brain reach the vessels of penis through the nerves. The vessels in response make Nitric Oxide in their endothelial cells. Nitric oxide once formed is pushed out from these cells and enter the lumen of the vessels where it stimulates the activation of guanylyl cyclase. Guanlyl cyclase splits GTP into cGMP. cGMP plays an important role in erection because its function is to dilate the blood vessels of the penis. Dilation of blood vessels causes the blood to ooze out from these vessels and enter the spaces inside the erectile tissue of the penis. Filling of the spaces causes erection. Viagra triggers erection by rendering an enzyme called phosphodiesterase unable to perform its action. Phosphodiesterase normally converts cGMP into GMP. When this enzyme is blocked, concentration of cGMP increases. Increased concentration of cGMP helps achieve strong erection.
