We're not ovary-acting. Ovarian cysts are so last decade... plus they never really were an actual part of this diagnosis, anyway
The old name for this condition is officially dead (well, being phased out); start using "Polyendocrine Metabolic Ovarian Syndrome" instead. A massive global consensus report appeared in The Lancet on May 12, 2026 with the update and the 56 organizations that agreed to the change.
This helps patients understand that their symptoms involve far more than just ovaries.
Why the new label? Polycystic was always a misnomer. Patients often worry about "cysts" that are simply follicles arrested in their development phase. Rather than being a condition affecting just the ovaries, PMOS is now easier to think about as a multisystem condition associated with diabetes, obesity, and even sleep apnea.
Diagnosis Once other disorders are ruled out, adults ≥20 years require two of the following for a diagnosis:
• Irregular periods
• Hyperandrogenism (clinical or biochemical)
• One of the following
Elevated anti-Müllerian hormone (AMH), OR
Polycystic ovaries on ultrasound ... (actually should we change that to Poly-follicular?)
Adolescents aged 10-19 require the first 2 for a formal diagnosis.
EXAM TIP:
Do not get tricked by the name. Review the above list to think about how you can diagnose this without using ultrasound - it is not mandatory. You can diagnose this condition using clinical hyperandrogenism and menstrual history alone in most adults.
CLINIC TIP:
Let's make the PMOSt of it! Don't miss the cardiovascular risk factor screening and management for these patients with this metabolic syndrome that affects many endocrine organs.
