Quizplus · Accepted Answer

Milk "letdown" or the release of milk from the breast occurs in response to the hormone oxytocin. Oxytocin is released in response to the suckling or nipple stimulation, which triggers the contraction of the milk ducts and leads to the release of milk. Prolactin is responsible for milk production, but not for milk letdown. Progesterone and estrogen play a role in breast development and preparation for lactation but not in milk letdown. Lactose is a sugar found in milk but is not responsible for milk letdown.
