The process of production and secretion of milk from the mammary glands of a female is called lactation. The enlargement of breasts during pregnancy and the onset of milk secretion occur under the standards of hormones from the ovary and the anterior pituitary gland.But the continued secretion of milk depends upon the presence of a sucking child.If the newborn infant is not breast fed, the breasts stop secreting milk after a few days and decrease in size. This is called feedback control.
Milk contains an inhibitory peptide. If the mammary glands are not fullyemptied, the peptide accumulates and inhibits milk production.In most species milk comes out of a mother’s nipples. Progesterone influences the growth in size of alveoli and lobes of mammary glands but afterwards progesterone level drops which triggers the onset of copious milk production. Like progesterone,estrogen level also drops after birth. Secretion and storage of milk begins by the influence of prolactin hormone secreted from the anterior pituitary gland.However the ejection of milk is stimulated by the hormone oxytocin, released from the posterior lobe of the pituitary gland.
