Mono- and plurihormonal thyrotropic
pituitary adenomas: Pathological, hormonal and clinical studies in 12 patients.
When circulating levels of thyroid hormones are low, the hypothalamus responds by releasing TRH, which then stimulates thyrotropic
cells in the anterior pituitary to produce and secrete TSH.
TSH and thyrotropic
agonists: key actors in thyroid homeostasis.
Human chorionic gonadotrophin (HCG), produced by the fertilized egg, has a thyrotropic
The blunting of serum TSH levels could be due to the thyrotropic
action on the thyroid gland of elevated serum concentrations of hCG near the end of first trimester, with a mirror image between peak hCG values and a nadir of serum TSH values.
A failure of thyrotropic
function on the part of pituitary or an atrophy or destruction of the thyroid gland leads to an inability of the thyroid to produce sufficient hormone to meet the requirements of the body.

hormones in the blood of Friesian cows at various reproductive stages.
