Viagra decreases erectile dysfunction symptoms by helping you get and keep an erection. Erections happen when a protein called cyclic guanosine monophosphate (cGMP) is released, causing more blood to flow into your penis. Then, another protein called phosphodiesterase-type 5 (PDE-5) breaks down cGMP, stopping the erection. In people having difficulty with erections, PDE-5 may work too quickly. Viagra works by blocking PDE-5 from working. This way, blood flow to the penis can occur and not be stopped by PDE-5.
