Last week, PCOS got a major rebrand.

Polycystic ovary syndrome (PCOS) will now be known as polyendocrine metabolic ovarian syndrome (PMOS). The main critique of the old name was that it inaccurately described the condition, which affects about 1 in 8 women worldwide. It implied that ovaries covered in many pathological cysts are a central feature of the syndrome, and that is not the case.
