Results are presented as mean (SD), min-max, unless stated otherwise. Some participants underwent more than one stimulation cycle; therefore, the number of cycles is higher than the number of donors.
*Blastocyst morphology assessed according to the Gardner and SART grading systems.
†Kruskal-Wallis test p value = 0.0359.
AMA, advanced maternal age. BMI, body mass index. HP-hMG, highly purified human menopausal gonadotropin. POR, poor ovarian reserve. r-hFSH, recombinant human follicle stimulating hormone, r-hLH, recombinant human luteinising hormone.
