1 One of these hormones (prolactin) acts on the milk-making tissue, building up the milk supply. 2  The other hormone (oxytocin) causes the breast to push out or release the milk already there. 3  This release of milk is known as the let-down reflex (sometimes called the milk ejection reflex). The more often your babyâs sucking causes a let-down and the more milk that is removed from your breasts, the more milk will be made. 2  Respond to your babyâs feeding cues. 3  Crying is a late sign of hunger. 4  Breastfeed your baby often.
Mammary gland. The mammary gland is a gland located in the breasts of females that is responsible for lactation, or the production of milk. Both males and females have glandular tissue within the breasts; however, in females the glandular tissue begins to develop after puberty in response to estrogen release.Mammary glands only produce milk after childbirth. During pregnancy, the hormones progesterone and prolactin are released.The progesterone interferes with prolactin, preventing the mammary glands from lactating. During this time, small amounts of a pre-milk substance called colostrum are produced.ammary glands only produce milk after childbirth.
