Values expressed as mean±standard deviation (SD). p-value < 0.05 was considered statistically significant. AMH: anti-Müllerian hormone; 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 complemented with Kruskal-Wallis test. bChi-square test. cLow-high comparison. dMiddle-high comparison.
