An online tool for predicting ovarian responses in unselected patients using dynamic inhibin B and basal antimüllerian hormone levels.

Early inhibin B might be a novel biomarker for predicting ovarian response in IVF cycles. Limiting the two prediction models to the high and the very-low risk groups would achieve satisfactory performances and clinical significance. These novel models might help in counseling patients on their estimated ovarian response and reduce iatrogenic poor or excessive ovarian responses.
