Milk production is stimulated by which hormones?

Explanation:
Milk production is driven by prolactin, which stimulates the mammary alveolar cells to synthesize and secrete milk. Progesterone helps prepare the mammary glands during pregnancy and, with its fall after birth, removes inhibition so lactation can begin. Oxytocin, by contrast, triggers milk let-down rather than production. Estrogen and testosterone have roles in gland development and other processes but are not the primary drivers of milk synthesis. So the combination of progesterone and prolactin best explains milk production.
