مستخلص:	It has been suggested that a progesterone/estradiol ratio (P/E2) ≥ 1.0 on the day of human chorionic gonadotropin (hCG) administration indicates premature luteinization and might be associated with an adverse pregnancy; however, a lower limit of this ratio has not been determined. We aimed to identify a lower limit of P/E2 that correlates significantly with an increase in adverse pregnancies in patients undergoing a prolonged in vitrofertilization/intracytoplasmic sperm injection therapy.
