The causes of endometritis in women may include unclean sex, infection of the lower genital tract, and unregulated uterine operations. 1. Unclean sex: due to multiple sexual partners and unclean sex, germs invade the uterus, thus causing endometritis. 2. Lower genital tract infection: frequent vaginal irrigation, lower genital tract pathogens retrograde into the uterine cavity, will cause endometritis. 3. Unstandardized uterine operations: when there are unstandardized uterine operations such as placing or removing the birth control ring, abortion, scraping, etc., it is easy to cause germs to invade the uterus, which will lead to endometritis. Female endometritis is a common type of gynecological inflammation, which occurs for many reasons. Endometritis in women requires further consultation with an obstetrician and gynecologist.
