Bacterial Vaginosis and Pregnancy: What's the Connection?
The bacteria that cause bacterial vaginosis can sometimes infect the uterus (womb) and fallopian tubes (tubes that carry eggs from the ovaries to the uterus). This type of infection is called pelvic inflammatory disease (PID).
PID can cause infertility or damage the fallopian tubes enough to increase the future risk of ectopic pregnancy and infertility. Ectopic pregnancy is a life-threatening condition in which a fertilized egg grows outside the uterus, usually in a fallopian tube, which can rupture.
Pregnant women with bacterial vaginosis are more likely to have babies who are born premature or with low birth weight (less than 5 pounds).
