*After ANCOVA with antral follicle count (AFC) as a covariate.
Values are presented as mean (standard deviation) or number (%). A p value of <0.05 was considered significant.
The p value was calculated after log transformation for normal distribution.
rFSH, recombinant follicle-stimulating hormone; hp-hMG, highly purified-human menopausal gonadotropin; GnRH, gonadotropin-releasing hormone; PPOS, progestin-primed ovarian stimulation; GT, gonadotropins; E2, estradiol; P, progesterone; hCG, human chorionic gonadotropin; MII, metaphase II.
