Endometriosis Impact on Oocyte Quality

Overview

The aim of this study is to evaluate the impact of endometriosis on folliculogenesis and oocyte quality. To do so, a metabolomic approach will be conducted in order to analyze the follicular fluid. This evaluation will be completed by a transcriptomic analysis from the cumulus cells of the oocyte. The normal and pathological oocyte cohort after controlled ovarian stimulation will be also characterized by identifying the oocyte leading to live birth.

Endometriosis pathophysiology remains under controversy. Among the various issues raised, that of his involvement in an implantation failure related to an alteration of the endometrium is advanced by some authors. For others, infertility would be linked to an alteration of the oocyte quality responsible for embryonic development impairment leading to a lack of implantation. Several research groups have also mentioned the association of the two mechanisms. The oocyte quality evaluation is also subject to controversy. Indeed, its morphological approach remains the most commonly used in routine at the IVF laboratory. However, this tool remains limited and to date, no correlation between oocyte morphology and ART outcomes have been established. In this context, there is a real need to use functional approaches such as genomics, transcriptomics, proteomics and metabolomics. However, the clinical validation and application of these functional tools have to be evaluated from a human pathology model such as endometriosis.
