hormone(redirected from testicular hormone)
Also found in: Thesaurus, Medical, Encyclopedia.
a. A substance, usually a peptide or steroid, produced by one tissue and conveyed by the bloodstream to another to effect physiological activity, such as growth or metabolism.
b. A synthetic compound that acts like a hormone in the body.
2. Any of various similar substances found in plants and insects that regulate development.
[From Greek hormōn, present participle of hormān, to urge on, from hormē, impulse; see er- in Indo-European roots.]
hor·mon′al (-mō′nəl), hor·mon′ic (-mŏn′ĭk) adj.
1. (Biochemistry) a chemical substance produced in an endocrine gland and transported in the blood to a certain tissue, on which it exerts a specific effect
2. (Biochemistry) an organic compound produced by a plant that is essential for growth
3. (Biochemistry) any synthetic substance having the same effects
[C20: from Greek hormōn, from horman to stir up, urge on, from hormē impulse, assault]
horˈmonal, hormonic adj
1. any of various internally secreted compounds formed in endocrine glands that affect the functions of specifically receptive organs or tissues when transported to them by the body fluids.
2. a synthetic substance that acts like such a compound when introduced into the body.
3. any of various plant compounds, as auxin or gibberellin, that control growth and differentiation of plant tissue.
[1900–05; < Greek hormôn, present participle of hormân to set in motion, stimulate, derivative of hormḗ impetus, impulse]
hor•mo′nal, hor•mon•ic (-ˈmɒn ɪk, -ˈmoʊ nɪk) adj.
A substance produced in one part of the body, especially in an endocrine gland, that has an effect on another part of the body, to which it is usually carried in the bloodstream. Hormones regulate many biological processes, including growth and metabolism.
Did You Know? On the inside, humans are bathing in a sea of hormones, chemical compounds that regulate many essential activities in the body. A lot of hormones are produced in glands known as endocrine glands, such as the thyroid gland, pancreas, and ovaries, and travel from there through the bloodstream before arriving at their target sites of action. Specialized cells of the nervous system also produce hormones. Hormones are not found only in humans, but also in all other animals and plants. The variety of different functions hormones have is astounding. Insulin, secreted by the pancreas, regulates the absorption of sugars in the body. Thyroid hormones regulate the rate of cell metabolism and affect many other processes, including reproduction. Growth hormone, secreted by the pituitary gland, controls growth of the body. Estrogen and testosterone control sexual development. Some of the hormones released in the brain, known as endorphins, act as natural painkillers. When the amounts of these or other hormones are abnormal, disease can result. Too little insulin causes diabetes, too little estrogen weakens the bones of older women, and too much growth hormone causes people to grow without stopping. Fortunately, these diseases can usually be treated, either with hormones made artificially in laboratories or by operating on the affected gland.
A chemical messenger that is produced in one part of an organism and acts in another part.

secretion - a functionally specialized substance (especially one that is not a waste) released from a gland or cell

Adrenalin, adrenaline, epinephrin, epinephrine - a catecholamine secreted by the adrenal medulla in response to stress (trade name Adrenalin); stimulates autonomic nerve action
glucagon - a hormone secreted by the pancreas; stimulates increases in blood sugar levels in the blood (thus opposing the action of insulin)
gonadotrophic hormone, gonadotrophin, gonadotropic hormone, gonadotropin - hormone secreted by the anterior pituitary gland and placenta; stimulates the gonads and controls reproductive activity
insulin - hormone secreted by the isles of Langerhans in the pancreas; regulates storage of glycogen in the liver and accelerates oxidation of sugar in cells
