This study utilized non-metric dimensional scaling ordination and UniFrac analysis to evaluate beta diversity in gastrointestinal and urogenital microbial compositions. The researchers compared patients with endometriosis against control subjects, stratifying the data by whether participants were receiving oral contraceptive pills or not. Key findings highlighted distinct microbial community structures between the endometriosis group and controls within both the gut and urogenital tracts, noting variations based on hormonal treatment status. This paper is centrally about endometriosis — specifically investigating the association between urinary estrogens, estrogen metabolites, and the microbiome composition in affected patients.

Abstract

Patients with endometriosis (P-EOSIS) and control subjects (control) were either receiving or not receiving hormonal treatment (OCPs). A. Gastrointestinal tract. B. Urogenital tract. (No-OCPs samples: fecal: n = 9; vaginal swabs: n = 8; OCPs samples: fecal: n = 20; vaginal swabs: n = 20).
