What AFC predicts poor ovarian response?

AFC <5-7 follicles (2-10 mm) predicts poor ovarian response (POR) per Bologna criteria. POR: previous cancelled cycle or <4 oocytes retrieved, AMH <0.5-1.1 ng/mL, or advanced maternal age (≥40). Adjusted stimulation protocols needed.

What AMH indicates OHSS risk?

AMH >3.5 ng/mL or AFC >15 indicates high ovarian response. OHSS risk is elevated with AFC >20 and predicted >20 oocytes. GnRH antagonist protocols, trigger with GnRH agonist instead of hCG, and freeze-all approach reduce OHSS.

How does AMH correlate with live birth rate per IVF cycle?

AMH predicts quantity (oocyte yield) better than quality. Live birth rate per cycle decreases with age regardless of AMH level. Low AMH at young age still allows successful IVF. High AMH at advanced age does not predict success as well.

IVF AFC and AMH Oocyte Yield Prediction

Predict IVF oocyte retrieval number from antral follicle count (AFC) and anti-Müllerian hormone (AMH). AFC <5 or AMH <0.5 ng/mL indicates poor ovarian response; AFC >15 or AMH >3.5 ng/mL indicates high response risk for OHSS.
