Other normal temperature variations include those related to the menstrual cycle. [19] [20] The temperature regulator's set point is reset during infections to produce a fever. [17] [21] [22] Organisms are capable of adjusting somewhat to varied conditions such as temperature changes or oxygen levels at altitude, by a process of acclimatisation.
Cortisol is a steroid hormone in the glucocorticoid class of hormones and a stress hormone. When used as medication, it is known as hydrocortisone. It is produced in many animals, mainly by the zona fasciculata of the adrenal cortex in an adrenal gland. [1] In other tissues, it is produced in lower quantities. [2]
[13] [21] In the condition, circulating testosterone levels are within or slightly above the normal male range, but DHT levels are low (around 30% of normal), [22] [better source needed] and the ratio of circulating testosterone to DHT is greatly elevated (at about 3.5 to 5 times higher than normal). [13]
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.
Testosterone (medication) Testosterone (T) is a medication and naturally occurring steroid hormone. [9] It is used to treat male hypogonadism, gender dysphoria, and certain types of breast cancer. [9][10] It may also be used to increase athletic ability in the form of doping. [9] It is unclear if the use of testosterone for low levels due to ...
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 (AR). Anabolic steroids have a number of medical uses, [1] but are also used by athletes to increase muscle size, strength ...

The pharmacology of testosterone, an androgen and anabolic steroid (AAS) medication and naturally occurring steroid hormone, concerns its pharmacodynamics, pharmacokinetics, and various routes of administration. Testosterone is a naturally occurring and bioidentical AAS, or an agonist of the androgen receptor, the biological target of androgens ...
