Anabolic processes build organs and tissues. These processes produce growth and differentiation of cells and increase in body size, a process that involves synthesis of complex molecules. Examples of anabolic processes include the growth and mineralization of bone and increases in muscle mass.
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.
Steroid hormones help control metabolism, inflammation, immune functions, salt and water balance, development of sexual characteristics, and the ability to withstand injury and illness. The term steroid describes both hormones produced by the body and artificially produced medications that duplicate the action for the naturally occurring steroids.
In human biology, the testosterone–cortisol ratio describes the ratio between testosterone, the primary male sex hormone and an anabolic steroid, and cortisol, another steroid hormone, in the human body. [1]
Some type of commonly prescribed steroids could lead to changes in the structure of the brain, researchers have claimed. Prolonged use of systemic glucocorticoids – widely used to treat ...
Whereas testosterone produced both anabolic and androgenic effects, despite the lack of clear boundaries between these effects, as there is a great deal of mutual overlap between them, [118] the relative potency of these effects exerted by testosterone can depend on various factors and is a topic of ongoing research. [119] [120]
