This review synthesizes evidence on chronic endometritis, finding it impairs endometrial receptivity and ART outcomes, and that CD138 staining is the diagnostic gold standard, with antibiotics improving pregnancy rates.

Abstract

Chronic endometritis (CE) is a persistent, often asymptomatic inflammatory condition of the endometrium, increasingly recognized as a potential contributor to infertility and recurrent implantation failure. Despite its clinical significance, CE remains underdiagnosed due to a lack of standardized diagnostic criteria and its subtle clinical presentation. Objective: This review aims to synthesize the current evidence on the pathophysiology, diagnosis, and treatment of CE, highlighting its impact on reproductive outcomes and the effectiveness of therapeutic interventions. A comprehensive literature review was conducted, analyzing 85 peer-reviewed studies published in the last decade, of which 65 were deemed relevant and retained for further analysis. These studies were selected based on their relevance to the pathophysiology, diagnostic methodologies, and treatment outcomes for CE, focusing on their implications for fertility and assisted reproductive technologies (ARTs). The findings suggest that CE is associated with impaired endometrial receptivity, increased inflammatory markers, and reduced implantation and pregnancy rates with ARTs. Histopathological assessment using CD138 immunostaining remains the gold standard for diagnosis, while hysteroscopy and molecular microbiological techniques provide complementary diagnostic value. Antibiotic treatment has been shown to significantly improve implantation rates and pregnancy outcomes, particularly in women with recurrent implantation failure. Emerging therapies, including probiotics and regenerative medicine approaches, are being explored as potential adjuncts to the conventional treatment. Early and accurate diagnosis of CE is essential for optimizing reproductive outcomes. Standardized diagnostic protocols and individualized treatment strategies are crucial for improving implantation success and pregnancy rates in affected women. Future research should focus on refining the diagnostic methods and exploring novel therapeutic options to enhance endometrial health and fertility outcomes.
