*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; BMI, body mass index; FSH, follicle-stimulating hormone; AFC, antral follicle count; GT, gonadotropins; E2, estradiol; P, progesterone; MII, metaphase II
Note: Standard reference ranges: FSH: 1-9.2 mIU/mL
