Could you please compare the actions of the hormones Prolactin and Oxytocin?
After birth, the mother’s estrogen and progesterone levels decrease thus causing the anterior pituatary to produce prolactin. Prolactin gets the breast ready to secrete milk. During lactation prolactin also synthesizes the milk. Prolactin production is stimulated by the infant suckling. Oxytocin is also a hormone that plays a role in lactation. Just as prolactin is stimulated by infant suckling, so is oxytocin. As the infant suckles, the posterior pituary is triggered to produce oxytocin. Oxytocin is responsible for the milk ejection reflex. This reflex is accomplished by oxytocin stimulating the myoepithelial cell around the nipple and allowing the milk to be expressed through the ducts and out the nipple.
