But after puberty, administration of testosterone does not affect penis size, and androgen deficiency in adult men only results in a small decrease in size. [56] Growth hormone (GH) and insulin-like growth factor 1 (IGF-1) are also involved in penis size, with deficiency (such as that observed in growth hormone deficiency or Laron syndrome ) at ...
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.

[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.
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). [ 10 ] [ 5 ] It has strong androgenic effects and moderate anabolic effects, which make it useful for producing masculinization and suitable for androgen ...
