Cenforce FM 100 mg is a medication primarily used to treat erectile dysfunction (ED) in men. Its active ingredient, Sildenafil Citrate, is a well-known PDE5 inhibitor that helps improve blood flow to the penis, making it easier to achieve and maintain an erection when sexually aroused. Here’s how it works:

1. Increased Blood Flow: When a man is sexually stimulated, the blood vessels in the penis relax and widen, allowing more blood to flow in. Cenforce FM 100 mg boosts this process by inhibiting the enzyme PDE5, which normally restricts blood flow by breaking down the molecules that help widen blood vessels.
   
2. Improved Erection: With the increased blood flow, men are more likely to achieve an erection when they become sexually aroused.
   
3. Enhanced Sexual Experience: By helping maintain an erection longer, the medication can improve sexual performance and overall satisfaction. It can reduce the anxiety and stress that come with erectile dysfunction, which can sometimes be a barrier to intimacy and connection.
   

However, it’s important to note that Cenforce FM 100 mg only works when there is sexual stimulation—it doesn’t automatically cause an erection on its own.
Always consult with a healthcare provider before using any medication to ensure it's suitable for your specific health needs and to discuss any potential risks or side effects.
