  1. PTD (preterm delivery:< 37 weeks of gestation), very PTD (very preterm delivery:< 32 weeks of gestation), LBW (low birth weight: birth weight < 2500 g);VLBW (very low birth weight: birth weight < 1500 g). Analyses were adjusted for age of embryo transfer, age of oocyte retrieval, infertility duration, endometrial thickness, embryo quality, number of embryos transferred, and embryo developmental stage
