A physician involved in the long push to change the name PCOS to PMOS takes us behind the scenes of this subtle yet consequential change

Rachel Feltman: For Scientific American โ€™s Science Quickly, Iโ€™m Rachel Feltman.

As you may recall from one of our recent news roundup episodes , the condition long known as polycystic ovary syndrome, or PCOS, is in the process of getting an official rebrand. The new nameโ€”polyendocrine metabolic ovarian syndrome, or PMOSโ€”was crafted with the intention of minimizing misconceptions about the disease and increasing the accuracy of diagnoses. But while changing one letter in an acronym might seem like a small shift, this new name is the result of years of international collaboration between clinicians, patients and even marketing consultants.

Todayโ€™s guest, Anuja Dokras, was one of the leaders of this 14-year effort . Sheโ€™s the director of the recently renamed Penn PMOS Center at Penn Medicine in Philadelphia. Sheโ€™s also the Founderโ€™s Professor of Obstetrics and Gynecology and Womenโ€™s Health at the University of Pennsylvania.

Feltman: Thank you so much for coming on to talk with us today.

Feltman: In reading about this name change, I was really impressed at what a huge, multiyear, you know, international effort it was. I would love to start with just sort of, when this began.

When did you and your colleagues start to talk about this being an issue that needed to be addressed?
