    Polycystic ovary syndrome (PCOS) has been renamed to polyendocrine metabolic ovarian syndrome (PMOS) after extensive scientific discussion.

  • 2

    The new name PMOS was chosen to provide a more accurate description of the condition, which does not always involve ovarian cysts.

  • 3

    The renaming process involved nearly 22,000 stakeholders, including doctors, researchers, and patients, emphasizing the need for stigma reduction and scientific accuracy.

  • 4

    While PMOS maintains a reference to the female reproductive system, it avoids the term 'ovary' to allow for broader implications and avoid stigmatization.

  • 5

    Concerns remain about the name change's impact on marketing and rebranding efforts for organizations previously associated with the PCOS acronym.
