Bacteria from a sexually transmitted infection in the cervix climb up into the uterus, fallopian tubes, and sometimes the belly, causing infection and scarring that never fully heals.
Invading Army Breaches the Castle Gate
Your cervix is a castle gate with a thick mucus moat—bacteria are the invading army. When the gate thins (during menstruation) or is forced open (by sexual contact pushing germs through), soldiers breach the wall and occupy the castle (uterus). They then march up the fortress towers (fallopian tubes), which have guards with sweeping brooms (cilia) meant to push invaders back down. But the castle's own defense troops (white blood cells) flood the towers with so much firepower—enzymes and inflammatory chemicals—that they destroy not just the invaders but also the broom-wielding guards and the tower walls themselves, leaving behind rubble and scarring. If the army is not defeated quickly by antibiotics, they fortify a stronghold (abscess) that can explode, spilling soldiers into the kingdom's streets (peritoneal cavity) and bloodstream, turning a localized siege into a empire-wide catastrophe.
