Testosterone is the primary male sex hormone and androgen in males. [3] In humans, testosterone plays a key role in the development of male reproductive tissues such as testicles and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair.
However, they are not typically sources of energy; in mammals, they are normally metabolized and excreted. Steroids play critical roles in a number of disorders, including malignancies like prostate cancer, where steroid production inside and outside the tumour promotes cancer cell aggressiveness.

Trenbolone is an androgen and anabolic steroid (AAS) of the nandrolone group which itself was never marketed. [clarification needed] Trenbolone ester prodrugs, including trenbolone acetate (brand names Finajet, Finaplix, others) and trenbolone hexahydrobenzylcarbonate (brand names Parabolan, Hexabolan), are or have been marketed for veterinary and clinical use.
A steroid hormone is a steroid that acts as a hormone. Steroid hormones can be grouped into two classes: corticosteroids (typically made in the adrenal cortex, hence cortico-) and sex steroids (typically made in the gonads or placenta ). Within those two classes are five types according to the receptors to which they bind: glucocorticoids and ...
List of steroidogenic enzymes. Steroid desmolases. Cholesterol side-chain cleavage enzyme (20,22-desmolase) – steroid synthesis. 17,20-Lyase (17,20-desmolase) – androgen synthesis. Steroid hydroxylases. 11β-Hydroxylase – corticosteroid synthesis. 17α-Hydroxylase – androgen and glucocorticoid synthesis.
Corticosteroid. Cortisol ( hydrocortisone ), a corticosteroid with both glucocorticoid and mineralocorticoid activity and effects. Corticosteroids are a class of steroid hormones that are produced in the adrenal cortex of vertebrates, as well as the synthetic analogues of these hormones.
Steroids. Legal status. In Wikidata. Glucocorticoids (or, less commonly, glucocorticosteroids) are a class of corticosteroids, which are a class of steroid hormones. Glucocorticoids are corticosteroids that bind to the glucocorticoid receptor [1] that is present in almost every vertebrate animal cell.
Anabolic steroids, also known as anabolic-androgenic steroids (AAS), are a class of drugs that are structurally related to testosterone, the main male sex hormone, and produce effects by binding to the androgen receptor. Anabolic steroids have a number of medical uses, [1] but are also used by athletes to increase muscle size, strength, and ...
