Erection begins with sexual stimulation. Sexual stimulation can be tactile (for example, by touching the penis) or mental (for example, by having sexual fantasies). Sexual stimulation or sexual arousal generates electrical impulses along the nerves going to the penis and causes the nerves to release nitric oxide, which in turn increases the production of cyclic GMP (cGMP) in the smooth muscle cells of the corpora cavernosa. The cGMP causes the smooth muscles of the corpora cavernosa to relax and allow rapid blood flow into the penis. The incoming blood fills the corpora cavernosa, making the penis expand. And just what exactly does nitric oxide do? Blood vessels use the chemical as a signal to surrounding muscles to relax, which increases blood flow -- a necessity for staying erect. generic levitra online no prescription
