What stimulates the let-down of milk?

Explanation:
Let-down of milk is the milk ejection reflex driven by oxytocin released from the posterior pituitary in response to nipple stimulation from suckling. Oxytocin causes the myoepithelial cells around the milk secretory units to contract, pushing milk into the ducts so it can be milked out. Prolactin, by contrast, stimulates milk production itself, not its ejection. Estrogen and growth hormone have other roles in the body and do not trigger the let-down reflex.
