PCOS is here to stay: does 'PMOS' truly reflect biological reality?

Area of Science:

• Reproductive Endocrinology
• Metabolic Disorders
• Medical Nomenclature

Background:

• Polycystic ovary syndrome (PCOS) is a complex endocrine disorder with significant metabolic and reproductive implications.
• The current nomenclature 'PCOS' is recognized as having limitations in fully encompassing the syndrome's multifaceted nature.
• A proposal to rename PCOS to 'polyendocrine metabolic ovarian syndrome' (PMOS) has emerged, reflecting contemporary scientific understanding.

Purpose of the Study:

• To critically evaluate the proposed renaming of PCOS to PMOS.
• To assess the conceptual, biological, and clinical implications of the new terminology.
• To examine the role of consensus methodology versus biological validity in disease nomenclature.

Main Methods:

• Critical analysis of the proposed PMOS terminology.
• Review of the rationale based on consensus and stakeholder engagement.
• Historical perspective on syndromic nomenclature.

Main Results:

• The proposed PMOS terminology may overemphasize endocrine and metabolic aspects, potentially underestimating ovarian dysfunction's centrality.
• The reliance on consensus methodology for the new name raises questions about its biological validity.
• The shift from PCOS to PMOS could represent a significant conceptual reframing of the syndrome, not just a terminological update.

Conclusions:

• The proposed transition from PCOS to PMOS warrants careful consideration due to potential conceptual and biological concerns.
• While patient and multidisciplinary input is crucial, consensus alone does not guarantee biological accuracy.
• The clinical utility and biological reflection of the proposed PMOS nomenclature remain subjects for further debate and investigation.
