The Embryo-endometrium Multifaceted Interface: Endometrial Cavity Molecular Microbiobial and Transcriptomic Signatures in Predictinf Pregnancy Outcome in Infertile Patients Undergoing Assisted Reproduction Technology Procedures

Sponsor: IRCCS San Raffaele

Summary

In reproductive medicine, a fundamental challenge is to evaluate the endometrial health status during the embryo implantation window as a limiting step in predicting the success of treatments of assisted reproduction technology (ART). Some highthroughput tools, recently developed by private genomics companies, are available in the market even if they have not been independently validated and have different limitations. We propose a prospective cohort study with the aim of validating the reliability and increasing efficacy of these tools. Endometrial fluid samples will be collected non-invasively from women undergoing ART cycles and isolated genetic materials will be subjected to 16S rRNA gene sequencing for microbiota profiling and to RNAseq analysis of RNA content of extracellular vesicles previously recognized as a tissue proxy in predicting endometrial receptivity. Clinical pregnancy rate/first cycle will be the target outcome used to assess the resulting predictive models. Ultrasonographic features of the endometrium will also be collected and accounted for in the predictive model.
