Abstract
Purpose: To investigate if the late follicular phase echo pattern is associated with pregnancy outcome in donors vs recipients. Methods: Infertile donors sharing eggs with recipients were retrospectively evaluated. The endometrial echo patterm was evaluated onthe day of human chorionic gonadotropin injection in donors and on the day before progesterone was given to recipients. Results: Almost twice as many donors conceived when the triple-line pattem was found compared to isoechogenic (IE)(51.5% or 52/101 vs 27.3%e or 6/22) but there were inadequate numbers in the IE group to show a significant difference. There was not even a trend for adifference in recipients (55.2%,37/67 vs. 53.8%,14/26). Conclusions: The trend in this study for higher pregnancy rates in COH cycleswith triple-line isoechogenic pattermn in the late follicular phase will prompt a study of a larger group of patients undergoing IVF-ET inthe modern era. If confirmed one treatment option would be to freeze and defer transfer to an estrogen/progesterone cycle.
