What is it
During a vaginal exam, a small plastic hook is used to make a tiny opening in the membranes, releasing amniotic fluid.
How your body works here
The amniotic sac normally cushions the baby's head and slowly bulges against the cervix during contractions. Rupturing it removes that cushion so the head presses directly on the cervix, and the sudden change in intrauterine pressure plus prostaglandin release from the exposed membranes usually intensifies contractions. It also starts a time window during which bacteria from the vagina can travel upward.

Risks (R)
- Once broken, the clock starts on infection risk over time.Review sources ↓
- Cord prolapse if the head is not well applied.Review sources ↓
- Loss of amniotic cushion may make contractions feel stronger.Review sources ↓
Alternatives (A)
- Wait for spontaneous rupture.Review sources ↓
- Continue labor without AROM and reassess.Review sources ↓
