Insulin resistance and compensatory hyperinsulinemia drive hyperandrogenemia in PCOS by disrupting the hypothalamus-hypophysis-ovary axis and directly stimulating ovarian steroidogenesis, creating a self-perpetuating vicious cycle.
For women with PCOS, managing insulin resistance is likely more critical for symptom control than focusing solely on reproductive aspects. Strategies that improve insulin sensitivity (such as dietary changes or specific medications like metformin, though not detailed here) may help reduce androgen levels and improve ovarian function.
Insulin appears to disrupt all components of the hypothalamus-hypophysis-ovary axis, and ovarian tissue insulin resistance results in impaired metabolic signaling but intact mitogenic and steroidogenic activity, favoring hyperandrogenemia, which appears to be the main culprit of the clinical picture in PCOS. In turn, androgens may lead back to IR by increasing levels of free fatty acids and modifying muscle tissue composition and functionality, perpetuating this IR-hyperinsulinemia-hyperandrogenemia cycle.

- 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
