Abstract
Fifteen patients, age 16 to 55, presented with amenorrhea-galactorrhea-hyperprolactinemia. Pituitary function was evaluated by bolus injections of insulin, luteinizing hormone-releasing hormone (LHRH), and thyrotropin-releasing hormone (TRH) in 13 and by LHRH and TRH in 2. Responses to growth hormone (GH), thyroid-stimulating hormone (TSH), cortisol (F), luteinizing hormone (LH), follicle-stimulating hormone (FSH), and prolactin were measured. GH, TSH, and F responses were normal in most cases. LH responses were decreased (P less than 0.025) in patients with abnormal sellar tomography, whereas FSH responses tended to decrease with elevated prolactin levels. Prolactin responses were absent in five of the seven cases which could be evaluated. The clinical value of such testing appears to be limited to an individualized basis, although some prognosis of ovulatory response to bromocriptine therapy may be obtained from the gonadotropin response.
