[Call attention to the role of chronic endometritis in recurrent pregnancy loss].

Chronic endometritis (CE) refers to the persistent inflammation of endometrium and is closely associated with infertility. Recurrent pregnancy loss (RPL), which has complex etiological factors, is two or more pregnancy loss of a couple before 20 weeks. However, CE is found in approximately 30% RPL patients, indicating that the endometrial immune microenvironment disorder caused by CE may play important role in RPL. Therefore, we should pay high attention and give CE screening to the RPL patients. Due to the inconsistent diagnostic criteria of CE, the relationship between RPL and CE remains controversial. Antibiotic is the primary treatment of CE. Using the higher CE diagnosis value can ensure effective treatment to RPL patient, and avoid the abuse of antibiotic. The effective treatment of CE can improve the pregnant outcomes of RPL patient.
