Prolactin LabCorp

Prolactin is secreted by the pituitary gland. There are only two major functions of prolactin, which is to induce milk production and develop nerve cells. Levels of prolactin that are more elevated have been associated with tumors involving the lungs, pituitary gland, and the kidneys. Prolactin is sometimes used by doctors to evaluate sexual dysfunction of unknown cause in both men and women. It seems that higher levels of prolactin may disrupt normal orgasm. Some drugs, supplements, and certain diseases may disrupt normal prolactin blood levels. These include hypothyroidism, antidepressants, estrogen, opioid pain killers, diuretics, and L-arginine.
