Several endocrine and metabolic changes occur in hyperthyroidism, among which also changes in prolactin secretion are present. Causes are numerous. However, a decreased content of prolactin in secretory granules of the lactotrophic cells in the adeno-hypophysis gland, e.i. a decreased prolactin pool, should be especially emphasized. Prolactin secretion of the adeno-hypophysis gland was examined in 30 hyperthyroid patients. Normoprolacinaemia was diagnosed in basal conditions, but prolactin response was not so great during stimulation tests (test with thyrotropic hormone and eglonylic test) and suppression tests (L-DOPA and bromo-cryptic test). This finding suggests the existence of a decreased prolactin pool in hyperthyroidism.

D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D011388 Prolactin A lactogenic hormone secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). It is a polypeptide of approximately 23 kD. Besides its major action on lactation, in some species prolactin exerts effects on reproduction, maternal behavior, fat metabolism, immunomodulation and osmoregulation. Prolactin receptors are present in the mammary gland, hypothalamus, liver, ovary, testis, and prostate.
