Infertility duration (years) 3.69 ± 2.64 3.44 ± 2.09 NS
BMI (kg/m2) 23.06 ± 3.47 22.87 ± 3.50 NS
Type of infertility    NS
 Primary infertility 326 (61.0%) 834 (60.1%)  
 Secondary infertility 208 (39.0%) 554 (39.9%)  
Basal FSH (IU/L) 7.61 ± 2.56 7.76 ± 2.72 NS
Basal LH (IU/L) 3.86 ± 1.91 4.05 ± 2.13 NS
Basal E2 (pg/ml) 44.84 ± 21.44 47.30 ± 31.22 NS

  1. Abbreviations: FSH follicle-stimulating hormone, LH luteinizing hormone, E2 estradiol
  2. Statistical differences were calculated using the Mann–Whitney U-test, except for “type of infertility,” for which the chi-square test was used
  3. Results are significantly different if P < 0.05. Values are expressed as mean ± standard deviation unless indicated otherwise (Type of infertility is expressed as the number of IVF cycles)
