Follicular factors, serum estradiol, and outcome of pregnancy following in vitro fertilization and embryo transfer.
Success rate of in vitro fertilization and embryo transfer (IVF-ET) depends upon clinical and laboratory variables. This study compared follicular measurements and serum estradiol (E2) between 23 delivered and 23 nonpregnant controls following IVF-ET. E2, number of large follicles (no.), E2/no. ratio, total diameter of large follicle (TD), and the E2/TD ratio were compared between the two groups and between 23 women who delivered and 10 who aborted. E2 (P = 0.03), E2/no. (P = 0.006), and E2/TD (P = 0.005) were found to differ significantly between delivered and controls and between delivered and those who aborted.
