A prolactin test measures the amount of this hormone in the bloodstream. In a woman who breastfeeds, the nursing baby's demand for milk actually controls the mother's supply. When a baby sucks at the breast, the woman's pituitary gland releases more prolactin into her blood, increasing her milk production.
What is hyperprolactinemia? Hyperprolactinemia is a condition in which a person has higher-than-normal levels of the hormone prolactin in the blood. The main function of prolactin is to stimulate breast milk production after childbirth, so high prolactin levels are normal in pregnancy. Prolactin also affects the levels of sex hormones (estrogen and testosterone) in both women and men. Prolactin is made by the pituitary gland, a pea-sized organ found at the base of the brain.
