To determine the optimal time to perform the endometrial biopsy for the detection of "out-of-phase" endometrium.Two endometrial biopsies were performed during a single menstrual cycle in each subject. The patient's chronological day was determined by counting forward from the midcycle LH surge, as assessed by urinary LH detection. The "early" biopsy was done on day LH + 7.4 +/- 0.8, and the "late" biopsy on day LH + 11.6 +/- 0.7. Each biopsy was independently read by two pathologists and was considered out of phase if the histologic date wasor = 3 days delayed compared with the chronological date.Infertility practice of an academic teaching hospital.Thirty-three ovulatory women seeking evaluation for infertility.Number of patients with out-of-phase endometrium detected by the early versus the late biopsy.There was a significantly greater detection rate for out-of-phase endometrium using the early biopsy (12.1% to 18.2% incidence depending on the observer) compared with the later biopsy (6.1% to 9.1% incidence). A majority of the early out-of-phase biopsies corrected by the time of the later biopsy.Our findings indicate that an endometrial biopsy performed in the midluteal phase may detect a greater number of women with delayed endometrial maturation during the temporal window of embryo implantation. The observation that most of the women with out-of-phase midluteal biopsies had normal late luteal endometrium may represent a cryptic form of luteal phase deficiency. |
