Sample item

Which hormone is primarily responsible for milk production?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Prolactin

Prolactin stimulates mammary milk synthesis after delivery, while oxytocin causes milk ejection in response to suckling and other stimuli.

Option by option

  • A. Prolactin (correct)

    Correct: prolactin drives milk synthesis.

  • B. Oxytocin

    Oxytocin causes milk let-down rather than production.

  • C. Progesterone

    Progesterone withdrawal permits lactogenesis but is not the primary secretory hormone.

  • D. Estrogen

    Estrogen levels fall after delivery and do not drive milk production.
