Cox proportional hazard modeling (Table 4) using the enter method by the age of women, BMI, AFC, duration of infertility, type and causes of infertility, basal FSH, cycle number, embryo pooling strategy, number of stimulation cycles per woman, number of oocytes obtained per woman, and total number of transferable embryos per woman, revealed that the embryo banking, age of women, number of stimulation cycles per woman were strongly associated with the CLBR after adjusting other confounding factors. This evidence concerns the gene BRD2 and Infertility.
