What is it

After the baby is born, the placenta is delivered with the body's natural contractions, without routine Pitocin or controlled cord traction.

How your body works here

After the baby is born, the uterus shrinks sharply, which shears the placenta off the uterine wall. Baby-led breastfeeding and skin-to-skin trigger natural oxytocin pulses that both deliver the placenta and clamp down the open blood vessels where it was attached. Active management gives synthetic oxytocin to guarantee that clamp-down and reduce hemorrhage risk; physiologic management relies on the body's own oxytocin surge.

Evidence summary

WHO and ACOG recommend active management to reduce hemorrhage risk in most settings. Physiologic third stage may be appropriate for select low-risk situations with experienced support.
