A hormone secreted by the hypothalamus that stimulates release of thyrotropin.
- ‘In patients with primary hypothyroidism, there is increased production of thyrotropin-releasing hormone, which may stimulate prolactin release.’
- ‘Low levels of thyroid hormone result in increased levels of the thyrotropin-releasing hormone, which increases prolactin secretion.’
- ‘Suckling, stress, dehydration, exercise, sexual intercourse and sleep increase the basal secretion rate from the pituitary gland, as do estrogen, thyrotropin-releasing hormone and possibly serotonin.’
- ‘The thyrotropin-releasing hormone level is another test of thyroid function.’
- ‘Secretion of TSH (also called thyrotropin), the final member of the glycoprotein hormone family, is stimulated by thyrotropin-releasing hormone, TRH from the hypothalamus.’
