It is characterized by the inability to achieve or maintain an erection that is sufficient for sexual activity.

Viagra works by increasing blood flow to the penis, which can help to improve erectile function. It does this by inhibiting an enzyme calledphosphodiesterase type 5(PDE5), which is responsible for breaking down a molecule called cyclic guanosine monophosphate (cGMP). When cGMP levels are elevated, blood vessels in the penis relax and widen, allowing more blood to flow in and creating an erection.
