  1. Abbreviations: FSH follicle-stimulating hormone; LH Luteinizing hormone; E2 estradiol;
  2. Statistical differences were calculated using the non-parametric Kruskal-Wallis H test, except for “type of fertilization” where the chi-square test was used
  3. Significant at P < 0.05. Values are expressed as mean ± standard deviation unless stated otherwise
