[b][url=https://www.genericday.com/aurogra-100-mg.html]Aurogra 100[/url][/b] mg works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). This enzyme normally breaks down cyclic guanosine monophosphate (cGMP), a substance that helps to relax and widen the blood vessels in the penis. By inhibiting PDE5, Aurogra allows cGMP to remain active for a longer period, which increases blood flow to the penis when a man is sexually stimulated. This results in a firm and lasting erection.
