To avoid potential deviation in the results and to further estimate the effects of confounding factors and P on pregnancy outcomes, we adjusted for female age at transfer, infertility duration, gravidity, parity, number of miscarriages, BMI, basal E2, basal FSH, AMH, genetic category, endometrial thickness, days of embryonic development, E2 on the trigger day, and Gn total dose. Here, AMH is linked to Infertility.
