PCOS guidelines: 2023 refines 2018, it does not reverse it

Did the 2023 PCOS guideline change everything? Not really. It builds on 2018 with the same evidence-based core, just a cleaner diagnostic pathway and broader recognition of what PCOS affects^[1].

The biggest diagnostic shift is refinement: adults still use the established framework, but 2023 simplifies the algorithm and adds AMH as an alternative to ultrasound in adults only^[2][3].

That matters because PCOS is not only a fertility diagnosis. The 2023 guidance more clearly flags metabolic risk factors, cardiovascular disease, sleep apnea, and very common psychological features^[4][5].

It also pushes care to be more practical and patient-centered: better clinician education, evidence-based patient information, improved models of care, and shared decision making^[6][7].
