Hyperprolatcinemia mildly elevated serum prolactin level may be due to a nonfunctioning pituitary adenoma or craniopharyngioma compressing the pituitary stalk, but high prolactin levels are commonly associated with a prolactin secreting prolactinoma.

Complete resection is difficult because prolactin producing tumor looks like the surrounding normal pituitary. Most cases of true hyperprolactinemia are associated with amenorrhea or hormone deprivation in premenopausal women and can be managed by dopamine agonist or hormone replacement therapy respectively. A mildly elevated serum prolactin level may be due to a nonfunctioning pituitary adenoma or craniopharyngioma compressing the pituitary stalk, but high prolactin levels are commonly associated with a prolactin secreting prolactinoma.

It is worth noting that many premenopausal women with hyperprolactinemia do not have galactorrhea, and many with galactorrhea hyperprolactinemia hypothyroidism not have hyperprolactinemia. Kisspeptin, when administered exogenously, has the ability to reverse the hypogonadotropic effects of hyperprolactinemia and can also restore pulsatile LH secretion. Unlike other tropic hormones secreted by the anterior pituitary gland, prolactin secretion is controlled primarily by inhibition from the hypothalamus and it is not subject to negative feedback directly or indirectly by peripheral hormones. In addition, menstrual disturbancies do not relate to hyperprolactinaemia in hypothyroidism.
