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 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 in-coming blood fills the corpora cavernosa, making the penis expand. Currently, any man who wishes to have erectile function can do so regardless of the etiology of the problem. Many therapeutic options are available, and the task of the physician is to help the patient seek the best solution. Finding a trained and understanding physician who is willing to take the time to understand the patient's problem is the first step in identifying which therapeutic option will ultimately be most appropriate and successful.
