Question

Which hormone stimulates the secretion of milk in female?

• A. LH
• B. Prolactin
• C. Oxytocin
• D. Progesterone

Answer 1

The correct option is B Prolactin

Prolactin (lactogenic hormone) is the hormone that stimulates milk secretion in lactating women. Prolactin stimulates mammary glands to produce milk. During pregnancy, prolactin helps in breast enlargement but due to the presence of high levels of progesterone and estrogen, milk secretion does not happen. Once women deliver, both progesterone and estrogen hormones levels drop and prolactin helps in secretion of milk.

So the correct answer is "Prolactin".
