Endometriosis impacts fertility by altering the crucial early dialogue between the embryo and the uterine lining. This study reveals molecular changes in endometriosis patients that disrupt this interaction, affecting in vitro fertilization (IVF) success.
Area of Science:
- Reproductive Biology
- Immunology
- Genomics
Background:
- Endometriosis affects 10% of women of reproductive age, with a known link to infertility.
- The precise mechanisms connecting endometriosis and infertility require further elucidation.
Purpose of the Study:
- To investigate the molecular mechanisms underlying the association between endometriosis and infertility.
- To compare IVF outcomes in women with and without endometriosis.
- To analyze the early embryo-endometrial dialogue in the context of endometriosis.
Main Methods:
- Retrospective analysis of IVF outcomes using euploid embryos in healthy versus endometriosis patients.
- Construction of an interactome network using RNAseq data from normal endometrium and blastocysts.
- Analysis of public RNAseq data from endometriosis patients to identify interactome alterations.
Main Results:
- Endometriosis patients required more IVF attempts, but pregnancy progression was similar once achieved.
- The embryo-endometrial interactome in normal endometrium is enriched in tissue remodeling, angiogenesis, and immune regulation pathways.
- Endometriosis alters these pathways and increases immune cell frequency/activation (NK, CD4+, CD8+), potentially disrupting embryo-endometrial dialogue.
Conclusions:
- Key molecular processes in early embryo-endometrial-immune cell interaction are affected by endometriosis.
- These alterations likely contribute to the fertility issues observed in endometriosis patients.
- Understanding these molecular disruptions may lead to improved fertility treatments for endometriosis.
