This is what the structures look like. Essentially, through sexual intercourse, a woman becomes infected with Gonorrhea or Chlamydia and possibly other infections that relate to upper genital tract infection and disease, including bacterial vaginosis. These infections ascend, infect the cervix (Gonorrhea and Chlamydia actually reside in the cervix), come up into the upper genital tract by traveling along the endometrial lining, traveling along the tubal structures, and actually can infect all of the pelvis to cause inflammation.
