Despite the extensive use of gonadotrophin releasing hormone agonists (GnRH ag) for pituitary downregulation, the literature regarding their effect on ultrasound parameters for predicting ovarian responses are few and conflicting. The aim of this prospective study was to compare antral follicle count (AFC), ovarian volume and ovarian stromal blood flow measured by three-dimensional (3D) power Doppler ultrasound before and after pituitary downregulation.
