Erectile dysfunction is the inability to obtain or maintain a satisfactory erection. The prevalence of erectile dysfunction varies with the age of the patient. About 16% of men between the ages of 50 and 59 will suffer from erectile dysfunction, and 44% of men between the ages of 70 and 75 will also suffer. But for this, it would be wise to take fildena 100 purple medicine. Because this pill improves the blood flow in men's penis and helps to get a better erection when sexually stimulated.
