Cenforce 120 is a medication used to treat erectile dysfunction (ED) in men, containing 120 mg of sildenafil citrate as its active ingredient. Sildenafil works by increasing blood flow to the penis during sexual stimulation, helping men achieve and maintain an erection. Cenforce 120 works by blocking the enzyme PDE5, which regulates blood flow in the penis. By inhibiting PDE5, the medication allows for stronger and longer-lasting erections. However, it does not increase libido or sexual desire; it only aids the physical process of erection.
