MICROANATOMY

Detailed explanation-1: -Prolactin. Prolactin is necessary for the secretion of milk by the cells of the alveoli. The level of prolactin in the blood increases markedly during pregnancy, and stimulates the growth and development of the mammary tissue, in preparation for the production of milk (19).

Detailed explanation-2: -The hormone prolactin controls the amount of milk you produce, and your body begins producing prolactin early in pregnancy. At first, the high levels of estrogen, progesterone and other pregnancy hormones suppress prolactin. Once you deliver the placenta, those pregnancy hormones drop and prolactin takes charge.

Detailed explanation-3: -Your central nervous system, immune system, uterus and mammary glands are also capable of producing prolactin. The following factors can contribute to prolactin creation in these tissues: Nipple stimulation.
