Abstract:The pattern of follicular and luteal phase levels of serum estradiol-17 beta (E2) and progesterone (P) are compared between 5 conception (group P) and 27 nonconception (group N) cycles of patients undergoing in vitro fertilization and embryo transfer. Follicle growth was induced with human pituitary gonadotropin and controlled by daily ovarian ultrasonography measuring the follicular diameters. Group N has significantly (p less than 0.025) higher E2 levels from day -10 up to d-6 as compared with the group P. T… Show more
