IVF in vitro fertilization
*P < 0.05 was considered statistically significant
a P values: Mann–Whitney U test for the duration of infertility, basal serum LH level, proportion of mature oocytes and rate of good quality embryos; t test for other continuous variables; chi-square or Fisher’s exact test for categorical variables
