How Viagra Works
Viagra’s effectiveness lies in its ability to enhance blood flow to the penis, which is crucial for achieving and maintaining an erection. Here’s how it works:
- Inhibition of PDE5: Viagra inhibits the enzyme phosphodiesterase type 5 (PDE5), which regulates blood flow in the penis.
- Increased cGMP Levels: By blocking PDE5, Viagra increases levels of cyclic guanosine monophosphate (cGMP), a molecule that relaxes smooth muscle and dilates blood vessels.
- Erection Facilitation: Enhanced blood flow leads to improved erections when combined with sexual arousal.

- Enhanced sexual confidence and performance.
