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]
MDCalc was founded by two emergency physicians, Graham Walker, MD, and Joseph Habboushe, MD, MBA, [5] and provides over 500 medical calculators and other clinical decision-support tools. [6] The MDCalc.com website was launched in 2005. [5] In 2016, MDCalc launched an iOS app, [7] followed by an Android app in 2017. [8]
Testosterone supplementation is also known to reduce the threshold for aggressive behavior in men. [10] The drug is a synthetic androgen and anabolic steroid and hence is an agonist of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT).

Figure 2. Numbering of carbon atoms in a prototypical steroid nucleus [3] The androgen backdoor pathways are vital for creating androgens from 21-carbon (C 21) steroids, known as pregnanes. A 21-carbon steroid is a steroid molecule with 21 carbon atoms, [25] hence, their chemical formula contains C 21. For example, the chemical formula of ...
As such, the distinction between the terms anabolic steroid and androgen is questionable, and this is the basis for the revised and more recent term anabolic–androgenic steroid (AAS). [70] [75] [218] David Handelsman has criticized terminology and understanding surrounding AAS in many publications.
Dihydrotestosterone (DHT, 5α-dihydrotestosterone, 5α-DHT, androstanolone or stanolone) is an endogenous androgen sex steroid and hormone primarily involved in the growth and repair of the prostate and the penis, as well as the production of sebum and body hair composition.
