Obesity suppresses testosterone levels, which increases the risk of erectile dysfunction and decreased sex drive in obese men. A study on lean and obese rats led by Tongjian You from the University of Massachusetts Boston found that eight weeks of aerobic exercise increased blood and testicular testosterone in obese animals. Exercise reduced fat cell inflammation in the obese animals, which might be the reason for improved testosterone secretion. Inflammation is linked to poor metabolic health, which increases the risk of chronic diseases and impairs sexual performance. Exercise can partially reduce the metabolic effects of obesity.
