Fildena 100 mg works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), leading to increased blood flow to the penis during sexual stimulation. This enhanced blood flow helps men achieve and maintain a firm erection, thereby improving erectile function. Erectile dysfunction can significantly impact a man's self-esteem and sexual confidence. By effectively treating ED, Fildena 100 mg can restore confidence in one's ability to perform sexually, leading to a more satisfying and enjoyable sexual experience.
