Cenforce is a sildenafil-based medicine marketed for the treatment of erectile dysfunction (ED) in adult men. Sildenafil belongs to the PDE5 inhibitor class and works by increasing blood flow to the penis during sexual stimulation, helping achieve and maintain an erection. For men with ED, sildenafil may improve erection quality and the ability to maintain an erection during sexual activity. It does not increase sexual desire and requires sexual stimulation to produce an erection. The appropriate strength should be determined according to individual health, response, and medical history.
