Stress, lack of sleep, lack of exercise, and vascular diseases can contribute to erectile dysfunction. For about 70% of men, taking PDE-5 inhibitors like Viagra helps, with the effect only occurring with sexual stimulation. If medications are not effective, there are alternative therapies such as vacuum pumps, injections into the corpus cavernosum, urethral applications, or implants. Lifestyle changes such as increased physical activity, reduced alcohol consumption, sufficient sleep, and stress reduction are important measures for preventing erectile dysfunction.
