Viagra, or sildenafil, primarily works by increasing blood flow to the penis. This happens through a specific mechanism involving a chemical called cGMP.
Normally, an enzyme called PDE5 breaks down cGMP, limiting blood flow. Viagra inhibits PDE5. This inhibition allows cGMP levels to rise. Higher cGMP levels relax the muscles in the blood vessels of the penis, leading to increased blood flow and facilitating an erection.
The effect is localized. While Viagra influences blood flow, it doesn’t significantly boost energy levels throughout the body. Increased blood flow to the penis is the key action.
Important Note: Viagra’s impact on blood flow is specific to certain blood vessels. It does not generally increase overall energy levels or provide a generalized boost to circulatory systems.
Consult your doctor before using Viagra, especially if you have underlying health conditions.
