In order to completely prevent weaker erections from occurring, cenforce 100 mg works by enhancing the blood flow mechanism in the male genital area. Upon sexual stimulation, sildenafil comes into action and begins to reduce pulmonary pressure. It releases the tension that has built up in the spongy pelvic organ muscles and opens the blood vessels that supply the penis. Men can therefore more easily get and maintain rock-hard erections for longer than usual when they are sexually aroused.
