Notes: data are reported as mean (standard deviation) or median [25–75%] or % (ratio). Abbreviations: FSH, follicle-stimulating hormone; E2, serum estradiol; hCG, human Chorionic Gonadotropin; OPU, oocytes pick-up; OSI, ovarian sensitivity index; MII, metaphase II; MI, metaphase I; ET, embryo transfer; cCPR, cumulative clinical pregnancy rate. 1 Calculated as: no. retrieved oocytes/FSH total dose × 1000. 2 Calculated as follows: MII rate: (no. MII oocytes/no. retrieved oocytes); fertilization rate: (no. fertilized oocytes/no. inseminated oocytes); cleavage rate: (no. embryos/no. fertilized oocytes); implantation rate: (no. gestational sacs/no. transferred embryos).
