Does Losing Weight Improve Erectile Dysfunction?

For men with overweight or obesity, losing weight may improve erectile dysfunction, although the benefit varies. Research suggests that meaningful weight loss can improve erectile-function scores, but a specific amount of weight loss does not guarantee a particular percentage of improvement. Excess weight contributes to ED through multiple mechanisms: it reduces testosterone levels, impairs blood flow to the penis, and increases inflammation that damages blood vessels. A landmark study of 110 obese men with ED found that those following a weight loss program had restored normal erectile function in 31% of cases after two years. Weight loss may support cardiovascular and metabolic health and can improve some factors associated with erectile function. Because persistent ED can also be related to cardiovascular disease, diabetes, medications, hormonal conditions, or other causes, it is important to discuss it with a healthcare professional.
