The diagnostic criterion for chronic endometritis (CE) is abnormal plasma membrane infiltration of the endometrial stroma. However, because most of CE patients have no obvious symptoms, some symptomatic patients are often confused with symptomatic treatment of pelvic inflammatory disease and vaginitis, so CE are often ignored in the clinic. In recent years, with the progress of the human microbiology program and human assisted reproductive technology, more and more studies suggested that there was a potential relationship between CE and reproduction-related diseases such as repeated pregnancy loss, repeated implantation failure and endometriosis. This article reviewed the research progress of CE and reproduction-related diseases.
