  1. Statistical differences were calculated using the Mann–Whitney U-test. Values are expressed as mean ± standard deviation unless indicated otherwise
  2. Clinical pregnancy rate, Spontaneous abortion rate, Live birth rate, Ectopic pregnancy rate, and Multiple pregnancy rate were calculated using the chi-square test or Fisher’s exact test
  3. Results are significantly different at P < 0.05
