The past two decades have seen a continuing explosion of new information on the physiology of penile erection and the pathophysiology of ED. These new discoveries not only enhance our understanding of the disease process but also provide a solid basis for improving our diagnosis and treatment. We can expect that the application of new research tools and information in molecular biology, signal transduction, growth factors, microarrays, and stem cells will bring the investigation of erectile function and dysfunction to an even higher level in the near future.
