Anabolic steroid use and testosterone replacement therapy (TRT) have been found to cause testicular atrophy through similar mechanisms. [2] [1] [17] Anabolic steroids and TRT are both used (either by prescription or illicitly) to mimic the effects of testosterone produced by the body, such as building muscle and maintaining sex drive.
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.
Testosterone levels increase in adolescence after puberty and into early adulthood, and naturally decline over time, usually starting in a man’s 40s or fifties. However, this drop now seems to ...
Dehydroepiandrosterone (DHEA) is a steroid hormone produced in the adrenal cortex from cholesterol. [5] It is the primary precursor of both the androgen and estrogen sex hormones. DHEA is also called dehydroisoandrosterone or dehydroandrosterone. Androstenedione (A4) is an androgenic steroid produced by the testes, adrenal cortex, and ovaries.
Some examples of virilizing effects are growth of the clitoris in females and the penis in male children (the adult penis size does not change due to steroids [medical citation needed]), increased vocal cord size, increased libido, suppression of natural sex hormones, and impaired production of sperm.

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.
Androstanolone, or stanolone, also known as dihydrotestosterone (DHT) and sold under the brand name Andractim among others, is an androgen and anabolic steroid (AAS) medication and hormone which is used mainly in the treatment of low testosterone levels in men. [2] It is also used to treat breast development and small penis in males. [2]
