When a man is sexually stimulated, the release of nitric oxide occurs in the erectile tissue of the penis. Nitric oxide activates an enzyme called guanylate cyclase, leading to an increase in cyclic guanosine monophosphate (cGMP) levels. This process causes the smooth muscles in the blood vessels of the penis to relax and widen, allowing increased blood flow to the penis, resulting in an erection.
