Abstract

Objective: To examine the usefulness of a trial cycle of hormone replacement therapy (HRT) and endometrial biopsy before the actual ET cycle in recipients of donated oocytes. Design: Retrospective review. Setting: Clinical practice at the South Texas Fertility Center, San Antonio, Texas. Patient(s): Thirty-six concurrent patients who underwent a trial cycle of HRT with endometrial biopsy before the ET cycle with donated oocytes fertilized in vitro. Intervention(s): Patients ≤40 years of age received 100 mg of IM progesterone in oil daily; patients <40 years of age received 50 mg daily. Endometrial biopsies were performed during the late luteal phase of the trial cycle. Main Outcome Measure(s): Histologic dating of the biopsy specimens was correlated with the chronologic date of the biopsy. Result(s): Five of 20 patients ≤40 years of age had out-of-phase biopsies. All 16 patients <40 years of age had in-phase biopsies. All out-of-phase biopsies subsequently were corrected with higher doses of progesterone. Pregnancy rates after fresh and frozen ETs were not significantly different between the two age groups. Conclusion(s): Patients ≤40 years of age are at risk of having out-of-phase endometrial biopsies while they are receiving standard HRT despite receiving higher doses of progesterone. Trial HRT cycles with endometrial biopsies are recommended.
