Can you get a pelvic infection from untreated B. V.?

Bacterial vaginosis is usually not serious. In some cases, however, it can cause infections in the uterus and fallopian tubes. It is important to treat bacterial vaginosis, especially before having an IUD inserted, an abortion, or tests done on the uterine lining. Both tricniasis and bacterial vaginosis have been linked to an increased risk of transmission of human immunodeficiency virus (HIV) and other ually transmitted diseases.
