Clinical Significance:
Prolactin is secreted by the anterior pituitary gland and is required for normal breast development and lactation in women. Prolactin levels will rise throughout gestation. In the absence of breast feeding, prolactin levels will return to normal within three weeks after birth. Abnormally high levels of prolactin are often associated with female infertility, impotence and infertility in males, primary hypothyroidism, and pituitary tumors.
