so I finally sat down and read the actual 2023 international pcos guideline update instead of just skimming summary articles, and one line stopped me cold. it says AMH can be used as an alternative to transvaginal ultrasound for confirming polycystic ovarian morphology, especially useful for lean patients where ultrasound findings get dismissed or missed. that’s exactly what happened to me.
my gyn never ordered an ultrasound at all, just did LH, FSH, testosterone, called it textbook pcos and moved on. i never questioned it bc the labs matched, but reading this made me realize how much of the diagnostic picture depends on which doctor happens to order which test that particular year. the guideline also pushes back on the “you don’t look like you have pcos” assumption, explicitly naming lean phenotype pcos with insulin resistance as underdiagnosed bc clinicians anchor on weight first.
that’s the piece nobody explained to me back in january. i’ve been logging cycle day, spiro timing, and energy crashes in careclinic since spring mostly bc i wanted charts instead of vague notes, and going back through the trend lines after reading this made a few odd energy dips make more sense once i lined them up with ovulation timing instead of just diet. anyone else’s diagnosis change shape once you actually read the source guideline instead of the patient-facing summary?
