239 women consecutively treated by IVF or ICSI were retrospectively analyzed and early luteal serum E2 and P were measured on the day of ET. Transfer occurred after a variable in vitro culture period ranging from 4-7 days after ovulation
Receiver-operator curve analysis demonstrated that the E2/P ratio could differentiate between clinical pregnancies
These retrospective data may hold prognostic value regarding endometrial receptivity as reflected by E2/P measurements and may help improve IVF treatment outcome. Further prospective studies should be undertaken to confirm these observation.
