adrenomedullary hormones  substances secreted by the adrenal medulla, including epinephrine and norepinephrine.

androgenic hormone  androgen.

anterior pituitary hormones  those produced in the adenohypophysis (anterior pituitary), including corticotropin, follicle-stimulating hormone, growth hormone, luteinizing hormone, prolactin, and thyrotropin.

antidiuretic hormone  vasopressin.

cortical hormone  adrenocortical h.

corticotropin-releasing hormone  (CRH) a neuropeptide elaborated mainly by the median eminence of the hypothalamus, but also by the pancreas and brain, that stimulates the secretion of corticotropin.

ectopic hormone  one released from a neoplasm or cells outside the usual source of the hormone.

eutopic hormone  one released from its usual site or from a neoplasm of that tissue.

fibroblast growth hormone  a peptide hormone secreted by the adenohypophysis that is a potent mitogen of vascular endothelial cells and a regulator of tissue vascularization.

follicle-stimulating hormone  (FSH) one of the gonadotropic hormones of the adenohypophysis; it stimulates ovarian follicle growth and maturation, estrogen secretion, and endometrial changes characteristic of the first portion of the menstrual cycle in females, and stimulates spermatogenesis in males.

follicle-stimulating hormone–releasing hormone  (FSH-RH) luteinizing hormone

gonadotropic hormone  gonadotropin.

gonadotropin-releasing hormone  (Gn-RH)

1. luteinizing hormone

2. any hypothalamic factor that stimulates release of both follicle-stimulating hormone and luteinizing hormone.

growth hormone  (GH) any of several related hormones secreted by the adenohypophysis that directly influence protein, carbohydrate, and lipid metabolism and control the rate of skeletal and visceral growth; used pharmaceutically as somatrem and somatropin.

growth hormone–releasing hormone  (GH-RH) one elaborated by the hypothalamus, stimulating release of growth hormone from the adenohypophysis.

inhibiting hormones  hormones elaborated by one body structure that inhibit release of hormones from another structure; applied to substances of established clinical identity, while those whose chemical structure is still unknown are called inhibiting factors.

interstitial cell–stimulating hormone  luteinizing h.

lactation hormone , lactogenic hormone prolactin.

local hormone  a substance with hormonelike properties that acts at an anatomically restricted site.

luteinizing hormone  (LH) a gonadotropin of the adenohypophysis, acting with follicle-stimulating hormone in females to promote ovulation as well as secretion of androgens and progesterone. It instigates and maintains the secretory portion of the menstrual cycle and is concerned with corpus luteum formation. In males, it stimulates the development and functional activity of testicular Leydig cells.

luteinizing hormone–releasing hormone  (LH-RH) a glycoprotein gonadotropic hormone of the adenohypophysis that acts with follicle-stimulating hormone to promote ovulation and promotes secretion of androgen and progesterone. A preparation of the salts is used in the differential diagnosis of hypothalamic, pituitary, and gonadal dysfunction and in the treatment of some forms of infertility and hypogonadism.

melanocyte-stimulating hormone , melanophore-stimulating hormone (MSH) one of several peptides secreted by the anterior pituitary in humans and in the rhomboid fossa in lower vertebrates, influencing melanin formation and deposition in the body and causing color changes in the skin of amphibians, fishes, and reptiles.

neurohypophysial hormones  posterior pituitary h's.

ovarian hormones  those secreted by the ovary, such as estrogens and progestational agents.

parathyroid hormone  a polypeptide hormone secreted by the parathyroid glands, which influences calcium and phosphorus metabolism and bone formation.

placental hormones  those produced by the placenta during pregnancy, including chorionic gonadotropin and other substances having estrogenic, progestational, or adrenocorticoid activity.

plant hormone  phytohormone.

posterior pituitary hormones  those released from the neurohypophysis (posterior pituitary), including oxytocin and vasopressin.

progestational hormone 

1. progesterone.

2. see under agent.

releasing hormones  hormones elaborated in one structure that cause the release of hormones from another structure; applied to substances of established chemical identity, while those whose chemical structure is unknown are called releasing factors.

sex hormones  the estrogens and androgens considered together.

somatotrophic hormone , somatotropic hormone growth h.

somatotropin-releasing hormone  (SRH) growth hormone

steroid hormones  those that are biologically active steroids; they are secreted by the adrenal cortex, testis, ovary, and placenta and include the progestogens, glucocorticoids, mineralocorticoids, androgens, and estrogens.

thyroid hormones  thyroxine, calcitonin, and triiodothyronine; in the singular, thyroxine and/or triiodothyronine.

thyroid-stimulating hormone  (TSH), thyrotropic hormone thyrotropin.

thyrotropin-releasing hormone  (TRH) a tripeptide hormone of the hypothalamus, which stimulates release of thyrotropin from the adenohypophysis and also acts as a prolactin-releasing factor. It is used in diagnosis of mild hyperthyroidism and Graves' disease, and in differentiating among primary, secondary, and tertiary hypothyroidism. A synthetic preparation is called protirelin.

follicle-stimulating hormone

n. Abbr. FSH

A glycoprotein hormone of the anterior pituitary gland that stimulates the Graafian follicles and assists in follicular maturation and in the secretion of estradiol. It also stimulates the epithelium of the seminiferous tubules and assists in inducing spermatogenesis. Also called follitropin.

Follicle-stimulating hormone (FSH)

A hormone produced by the pituitary gland that stimulates the follicles in the ovaries to swell and release ripe ova. Doctors sometimes use its levels in a woman's blood to evaluate whether she is in menopause.

follicle-stimulating hormone (FSH),

a gonadotropin that stimulates the growth and maturation of graafian follicles in the ovary and promotes spermatogenesis in the male. It is secreted by the anterior pituitary gland. FSH-releasing hormone produced in the median eminence of the hypothalamus controls the release of FSH by the pituitary. Increasing amounts of FSH are secreted in the postmenstrual or resting phase of the menstrual cycle, causing a primordial follicle to develop into a mature graafian follicle containing a mature ovum. The graafian follicle produces estrogen, which reaches a high level before ovulation and suppresses release of FSH. In males FSH maintains the integrity of the seminiferous tubules and influences all the stages of spermatogenesis. It may be used to treat some conditions. One form with luteinizing hormone (menotropins) is derived from the urine of postmenopausal women.

one of the gonadotropic hormones of the anterior lobe of the pituitary gland that stimulates the growth of graafian follicles in the ovary, and stimulates spermatogenesis in the testis. Abbreviated FSH.
