*To evaluate the LH effect on pregnancy outcomes, the higher LH group was taken as reference. aAdjusted for ET strategy (fresh vs. freeze-all), female age, infertility duration, baseline FSH and LH levels, total Gn dose, dose of GnRH antagonists and rLH supplementation, E2 levels at trigger day, and oocytes count. bAdjusted for dose of GnRH antagonists, progesterone and LH levels at trigger day, endometrial thickness at trigger day, and number of embryos transferred. cAdjusted for dose of GnRH antagonists, type and duration of infertility, baseline LH levels, E2 and LH levels at trigger day, and oocytes count. dAdjusted for the total Gn dose, dose of rLH supplementation, E2 levels at trigger day, oocytes count, number and stage of embryos transferred. eAdjusted for female age, duration of infertility, baseline FSH and LH levels, dose of Gn and rLH supplementation, E2 levels at trigger day, and oocytes count.
CLBR, cumulative live birth rage; LBR, live birth rate; FET, frozen-thawed embryo transfer.
