Viagra effect on ED; what needs to be present in adequate levels for viagra to result in an erection?
Viagra-like drugs artificially shore up cyclic GMP levels by inhibiting its breakdown and will produce an adequate erection provided there is sufficient nitric oxide to stimulate enough cyclic GMP.
Although we now realize that they do stimulate NO, they do not fully correct deficiencies of NO due to poor lifestyle choices. Think of a simple analogy of a fire hose that will become distended if the nozzle is partially closed off, but not if the fire hydrant is partly shut or there is not enough water in the system. It is crucial to have enough NO production for erection to occur, with or without the use of drugs.
