    Study Notes

    Hormones and Milk Production

    • Prolactin is the primary hormone responsible for milk production.

    Lactogenesis II

    • The hormone prolactin triggers the onset of milk production (Lactogenesis II).
    • The suckling of the baby by the mother triggers the release of prolactin, which in turn triggers Lactogenesis II.

    Regulation of Milk Production

    • Prolactin primarily regulates the volume of milk produced.

    Stimulating Milk Production

    • Frequent and effective suckling by the baby can stimulate milk production in mothers.
    • Skin-to-skin contact between the mother and baby can also stimulate milk production.

    Delaying Lactogenesis II

    • Stress, anxiety, and pain can delay Lactogenesis II in some mothers.
    • A caesarean section or other complications during childbirth can also delay Lactogenesis II.
