#235 : The Impact of Endometrial Scratch Performed in Mid-Luteal Phase on the Endometrium Whole Genome Transcriptomic Profiles in Following Menstrual Cycle

Abstract

Background and Aims: To verify whether endometrial scratch in mid-luteal phase affect the genomic characteristics of peri-implantation endometrium in the following cycle. Method: A Retrospectively self-control cohort study was conducted in a university assisted reproductive unit. A total of eight women with recurrent implantation failure were included. Each participant had endometrial biopsy twice, one biopsy was done on day LH+7 in a natural cycle, and the second biopsy was performed on day LH+7 of the following cycle. R package was used for identifying differentially expressed genes between the first biopsy group and the second biopsy group, and for gene set enrichment analysis. Results: The paired sample showed no significant difference in gene expression profiles of endometrium before and after endometrial scratch. Conclusion: It suggests that endometrial scratch performed during previous mid-luteal phase did not affect the genomic profiles of endometrium on day LH+7 in women with recurrent implantation failure.
