Work path for Generic Viagra
 
When a man is sexually excited, the penis experiences immediate effect with increased blood flow that results in an erection. Generic Viagra works by increasing blood flow to the penis, as well as causing penile muscles to relax. This medication just initiates healthy erection but never generates erection on consumption. This is a common misconception that has led to widespread disappointment. Scientists have found in research that in men suffering from erectile dysfunction, an enzyme constricts blood flow to the penis. This enzyme is known as phosphodiesterase type 5 better understood as PDE5. Generic Viagra stores blood flow in an already-stimulated penis by inhibiting the action of this enzyme.
