Abstract

OBJECTIVE: To determine whether exposure of developing endometrium to supraphysiologic E2 levels during controlled ovarian hyperstimulation (COH) in IVF cycles inhibits endometrial receptivity.

DESIGN: Retrospective analysis of IVF-ET and ovum donation data.

SETTING: Tertiary-care teaching hospital.

PATIENT(S): Four hundred ten patients(age) and their associated ovum recipients.

MAIN OUTCOME MEASURE(S): Implantation, pregnancy, and delivery rates.

RESULT(S): Ovarian response to COH (duration of stimulation, peak E2 level, area under the curve for E2 exposure, and number of oocytes retrieved) was similar for IVF-ET patients and ovum donors. Donors were younger than IVF-ET patients (mean age, 27.5 +/- 0.2 years vs. 30.4 +/- 0.1 years). A similar number of embryos with similar number of blastomeres were transferred in IVF-ET patients and ovum recipients. The fragmentation rate at time of transfer differed slightly between groups (5.2 +/- 0.2% vs. 4.3 +/- 0.3%). Implantation, pregnancy, and delivery rates did not differ between IVF-ET patients and recipients of donor oocytes.

CONCLUSION(S): Exposure of the developing endometrium to controlled ovarian hyperstimulation during IVF cycles does not inhibit embryo implantation or affect pregnancy and delivery rates.
