Prolactin is the hormone involved in milk secretion by alveolar cells in the mammary tissue. It stimulates the growth and development of mammary tissue during pregnancy, and levels rise after delivery. During breastfeeding, when the baby suckles, the anterior pituitary increases prolactin production and secretion, which stimulates breast milk production by the alveoli.
