Values expressed as mean±standard deviation (SD). p-value < 0.05 was considered statistically significant. BMI: body mass index; FSH: follicle-stimulating hormone;
LH: luteinizing hormone; β-HCG: beta-human chorionic gonadotropin; IU: international units; NS: not statistically significant. aANOVA test. bChi-square test.
