WebJun 14, 2024 · Secretion of the thyroid hormones T4 (thyroxine) and T3 (triiodothyronine) is regulated by pituitary thyroid-stimulating hormone (TSH) ( figure 1 and figure 2 ). TSH secretion, in turn, is controlled through negative feedback by thyroid hormones (see "Thyroid hormone synthesis and physiology"). WebTSH then stimulates cells in your thyroid to release thyroxine or T4 (80%) and triiodothyronine or T3 (20%) into your bloodstream. These two hormones prevent your pituitary gland from producing more TSH if the levels of thyroxine and triiodothyronine are too high, thus completing the cycle. When T4 and T3 levels drop, the cycle starts over again.
