Since prolactin was shown by Kleinberg and Frantz (1) to be a hormone separate from human growth hormone and since the development of radioimmunoassays for prolactin (2), the diagnosis of hyperprolactinemia as a cause of galactorrhea and amenorrhea has become common. Among unscreened women with amenorrhea, 15% to 25% may have elevated levels of prolactin; if one preselects for galactorrhea, the incidence is even higher (3).
