Tropic hormones are hormones produced and secreted by the anterior pituitary which target endocrine glands.[1] Tropic hormones include:
- Thyroid-stimulating hormone (TSH or thyrotropin) – stimulates the thyroid gland to make and release thyroid hormone.[2]
- Adrenocorticotropic hormone (ACTH or corticotropin) – stimulates the adrenal cortex to release glucocorticoids.[3]
- Luteinizing hormone (LH) – stimulates the release of steroid hormones in gonads—the ovary and testes.[4]
- Follicle-stimulating hormone (FSH) – stimulates the maturation of eggs and production of sperm.[5]
The hypothalamus controls the release of tropic hormones by secreting a class of hypothalamic neurohormones called releasing and release-inhibiting hormones—which are released to the hypothalamo-hypophyseal portal system and act on the anterior pituitary.[6]
