Verified step by step guidance1
Identify the hormones listed in the problem: Estrogen, Prolactin, Progesterone, and Oxytocin.
Understand the role of each hormone in the context of childbirth and lactation: Estrogen and Progesterone are primarily involved in preparing the body for pregnancy and maintaining it, while Oxytocin is involved in milk ejection (let-down reflex).
Focus on Prolactin, which is specifically responsible for stimulating and sustaining milk production in the mammary glands after childbirth.
Recognize that Prolactin is secreted by the anterior pituitary gland and plays a crucial role in lactation by promoting the synthesis of milk proteins and other components necessary for milk production.
Conclude that Prolactin is the hormone responsible for sustaining milk production after childbirth, distinguishing its role from the other hormones listed.
