WebIncreased TSH, in turn, stimulates the thyroid gland to produce and release more thyroid hormones (TH). The presence of a thyrotrope cell derived pituitary tumor would therefore lead to an increase in TRH, which would then cause an increase in TSH and an increase in thyroid hormones (TH). This is the most likely scenario, as indicated by option A.

In contrast, elevated blood levels of THs inhibit the release of TRH and TSH. During pregnancy, human chorionic gonadotrophin (hCG), produced by the placenta, binds to the TSH receptor and activates the maternal HPT axis, stimulating TH synthesis.
Webbut biologically subpotent TSH are found in the circulation in the presence of a reduced free T4. (38) Chronic TRH administration to such patients normalized the glycosylation process enhancing both its TSH-R binding affinity as well as its capacity to activate adenyl cyclase. This, in turn, can normalize thyroid function in such patients.
