TESTOSTERONE
| Pronunciation (US): |  | (GB): | |
I. (noun)
Sense 1
Meaning:
A potent androgenic hormone produced chiefly by the testes; responsible for the development of male secondary sex characteristics
Classified under:
Hypernyms ("testosterone" is a kind of...):
androgen; androgenic hormone (male sex hormone that is produced in the testes and responsible for typical male sexual characteristics)
Context examples:
As men age, the level of the male hormone testosterone usually drops.
(Hormone treatment studied in older men, NIH)
Treatment with cyproterone alone results in incomplete suppression of serum testosterone levels.
(Cyproterone acetate, NCI Thesaurus)
Administration of this agent may suppress testosterone production by both the testes and the adrenals to castrate-range levels.
(Abiraterone, NCI Thesaurus)
This species is nonmotile, catalase and urease positive, acid-fast, oxidase negative, hydrolyzes casein, elastin, esculin, hypoxanthine, testosterone, and tyrosine, but not xanthine, produces acid phosphatase, and reduces nitrate.
(Nocardia brasiliensis, NCI Thesaurus)
Nilutamide preferentially binds to androgen receptors and blocks androgen receptor activation by testosterone and other androgens; this agent may inhibit androgen-dependent growth of normal and neoplastic prostate cells.
(Nilutamide, NCI Thesaurus)
There are also health conditions that only affect men, such as prostate cancer and low testosterone.
(Men's Health, NIH)
This species is nonmotile, catalase and urease positive, reduces nitrate, hydrolyzes esculin, hypoxanthine, and xanthine, but not casein, elastin, testosterone, or tyrosine.
(Nocardia otitidiscaviarum, NCI Thesaurus)
Anabolic steroids are made in the laboratory from testosterone (a male hormone).
(Anabolic steroid, NCI Dictionary)
A steroid hormone that is a mixture of alpha and beta isomers, which have different orientations for the hydrogen group at position 5. 5alpha-androstanedione is a metabolic precursor for both testosterone and estrone.
(Androstanedione, NCI Thesaurus)
Abiraterone inhibits the enzymatic activity of steroid 17alpha-monooxygenase (17alpha-hydrolase/C17,20 lyase complex), a member of the cytochrome p450 family that catalyzes the 17alpha-hydroxylation of steroid intermediates involved in testosterone synthesis.
