Bariatric surgery reverses obesity-associated secondary hypogonadism (MOSH) in men, leading to increased total and free testosterone levels and improved sexual function.
If you are a severely obese man with low testosterone, bariatric surgery can naturally restore your hormone levels and sexual function by reversing the obesity that was suppressing your hormones.
GoodSupportsMEDIUM confidence
Increase in total and free testosterone levels as well as SHBG and gonadotropins (simultaneous increases in LH and FSH). MOSH reversal that occurred early after surgery and was nearly complete.
Why this rating
Supported by prospective studies, though some studies show mixed results on sexual dysfunction improvement.

- Bariatric surgery leads to long-term nutrient deficiencies (anemia, neuropathies, osteoporosis) due to malabsorption and reduced gastric acid, requiring lifelong monitoring and supplementation.Strong
- Bariatric surgery induces early, pronounced improvements in hepatic and peripheral insulin sensitivity and glycemic control that occur independently of significant weight loss, primarily through anatomical remodeling of the gastrointestinal tract.Good
- Bariatric surgery resolves Polycystic Ovary Syndrome (PCOS) symptoms, including menstrual irregularities and hirsutism, and improves fertility in obese women, largely through weight loss and hormonal normalization.Good

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
