What causes an ectopic pregnancy?
An ectopic pregnancy occurs when an embryo implants in a place other than the uterus, usually a fallopian tube. This occurs when an embryo cannot travel through a fallopian tube because it has been blocked, narrowed, damaged, or is abnormal. This can be caused by: previous infections including pelvic inflammatory disease; surgery including tubal sterilization, and; defects of the fallopian tube from birth.
