This review synthesizes, from PubMed/UpToDate/eLibrary literature from the past decade, evidence on how the uterine microbiota and “endometrium bacterial contamination” may contribute to adenomyosis pathogenesis. It discusses diagnostic approaches to characterize uterine cavity microbiota, emphasizing cultural and molecular methods such as 16S rRNA–based analysis, and proposes a paradigm in which bacterial contamination triggers cell modifications that amplify a vicious cycle of pathology and progression. A key caveat is that the paper is based on analysis of previously published studies rather than new primary experiments, and it centers on mechanistic concepts drawn from heterogeneous work. Relevance to endometriosis: the review frames adenomyosis within a broader context of endometriosis as a multifactorial, incompletely understood disease and repeatedly uses parallels between endometriosis and adenomyosis pathogenesis concepts, though the paper’s main focus is adenomyosis and uterine microbiota mechanisms.

Abstract

Endometriosis is a multifactorial disease that affects mainly women of reproductive age. The exact pathogenesis of this disease is still a mystery. The analysis of modern etiology concepts and mechanisms of adenomyosis development were carried out. The review includes data from foreign articles published in the PubMed, UpToDate, eLibrary databases over the past ten years. A number of works presenting studies of the uterus microbiota and its influence on the disease development were analyzed. The possibilities of cultural and molecular genetic diagnostic methods, in particular 16S rRNA, in studying the state of the uterine cavity microbiota are described. The modern paradigm of the development and progression of adenomyosis provides for the presence of endometrium bacterial contamination which, in turn, is a trigger for cell modifications activating a vicious circle of pathology.
