Like all things, the dose matters! A moderate amount of exercise can increase levels of hormones in the body including testosterone, cortisol, prolactin, and oxytocin — all of which play a role in your sex drive. Exercise also improves blood flow and reduces risk factors for diseases that are associated with sexual dysfunction including cardiovascular disease, obesity, and diabetes. A weekly exercise duration of 160 minutes has been shown to improve symptoms of erectile dysfunction that were related to improved cardiovascular and metabolic health.[1] Performing pelvic floor (i.e., Kegel) exercises may also strengthen lower pelvic muscles and improve erectile function and satisfaction. On the other hand, extreme levels of exercise may cause libido to fall drastically.
