The thyroid-stimulating hormone (TSH) is secreted by the pituitary gland, a pea-sized gland in your brain, and is part of the endocrine system. TSH regulates the thyroid gland, and the production of the thyroid hormones T4 (thyroxine) and T3 (triiodothyronine) that control your metabolism, growth and development, as well as body temperature.
