The name Polycystic Ovary Syndrome has caused confusion for years because ovarian cysts are not required for someone to have PCOS. What are commonly described as “cysts” in PCOS are actually ovarian follicles. Experts have raised concerns for years that the name doesn't accurately represent the complexity of the condition. This I can personally confirm.
That is one reason the transition to Polyendocrine Metabolic Ovarian Syndrome (PMOS) feels meaningful to me.
