Intrauterine Microbiota in Chronic Endometritis Patients Based on 16s rRNA sequencing Analysis

Chronic endometritis (CE) is a disease of continuous and subtle inflammation occurred in the endometrial stromal area, which is often asymptomatic or present with non-specific clinical symptoms. This study investigated the composition and distribution of the intrauterine microbiota of 71 patients who underwent hysteroscopy during the routine clinical inspection of infertility. Among them, patients who diagnosed as chronic endometritis (CE) were allocated into CE group (n = 29) and others into non-CE group (n = 42).
