Sequential low-dose step-up and step-down protocols with recombinant follicle-stimulating hormone in polycystic ovary syndrome: prospective comparison with step-down protocol

摘要

Purpose To assess the differences in follicular development comparing two sequential low-dose step-up and step-down protocols (A: 37.5 IU/day, B: 75 IU/day) with a step-down protocol (C: 150 IU/day) using recombinant human follicle stimulating hormone (rFSH) in women with polycystic ovarian syndrome (PCOS).
