A Study to Analyze the Microbiome and Immunology of the Lower and Upper Female Reproductive Tract in Women with Endometriosis

Overview

About this study

The purpose of this study is to map the female reproductive tract microbiome in patients with and without endometriosis to seek correlations of the microbiome to endometriosis, to determine if lower reproductive tract microbiome is predictive of upper reproductive tract changes by comparing composition of the microbiome in the lower and upper reproductive tracts, to explore immunologic differences in patients with and without endometriosis, compare presence of immunologic factors and cells between ectopic and eutopic endometrium, and to compare systemic immune system characteristics in patients with and without endometriosis using mass cytometry of peripheral blood samples.
