Cenforce 100mg works by relaxing the blood vessels in the penis and increasing blood flow when a man is sexually aroused. This increased blood flow helps to achieve and maintain a firm and satisfying erection. It’s important to note that Cenforce 100mg only works in the presence of sexual stimulation—it doesn’t create an erection on its own or increase sexual desire. The Cenforce 100mg dose is considered a standard and effective strength for men with moderate to severe ED. It’s typically taken 30 to 60 minutes before sexual activity, and its effects can last up to 4 to 6 hours, depending on the individual.
