New studies suggest that Sexual dysfunction that commonly occurs in morbidly obese men improves after gastric bypass surgery. Dr. Ramsey M. Dallal from Albert Einstein Healthcare Network, in Philadelphia and colleagues measured the degree to which 97 morbidly obese men suffered from sexual dysfunction and then analyzed the change in sexual function after substantial weight loss following gastric bypass surgery.

After losing an average of two thirds of their excess weight, men experienced significant improvements in all domains of the BSFI (Brief Male Sexual Function Inventory) scores, with the amount of weight loss proportional to the degree of improvement.

"Sexual function improves substantially after gastric bypass surgery to a level that reaches or approaches age-based norms." According to Dr. Dallal "Sexual dysfunction in this population is not likely secondary to psychological illness and not necessarily secondary to the presence of diabetes and hypertension."
