Bariatric surgery resolves obesity-associated gonadal dysfunction (PCOS in women, MOSH in men) in the vast majority of severely obese patients, with resolution rates of 96% for PCOS and 87% for MOSH.

If you are severely obese and have been diagnosed with PCOS or Male Obesity-Associated Secondary Hypogonadism (MOSH), bariatric surgery is the most effective treatment for resolving these conditions. Unlike diet or medication which often only manage symptoms, surgery addresses the underlying metabolic drivers, leading to resolution in nearly all women with PCOS and most men with MOSH. Consult a bariatric specialist to see if you are a candidate.

After bariatric surgery, resolution of PCOS was found in 96% (95CI 89–100) of affected women and resolution of MOSH occurred in 87% (95CI 76–95) of affected men.
