There is no one most effective treatment for erectile dysfunction (ED), as the cause of ED can vary from person to person.
However, some treatments that may be effective for ED include oral medications such as phosphodiesterase inhibitors (such as sildenafil, tadalafil, and vardenafil), penile injections (alprostadil), vacuum erection devices, and surgery.
Lifestyle changes such as quitting smoking, losing weight if obese, exercising regularly, reducing stress levels, and eating a healthy diet can also help improve ED.
