Testosterone also impacts pre-pubescent penis size by providing penile tissue with girth and density. The drop in testosterone values is mainly due to significant impairment of Leydig cells brought upon by hypogonadism. Leydig cells are located in the testes and serve to create testosterone and androgen.
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.
That's why 21-carbon steroids are denoted as C 21-steroids, 19-carbon steroids are denoted as C 19 steroids, and so on. [29] The androgen backdoor pathways occur without the involvement of testosterone (T) and/or androstenedione (A4), which are part of the conventional, canonical (classic) [30] [31] [11] androgenic pathway.

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.
Anabolic steroids influence cellular differentiation while favoring the development of muscle cells over fat-storage cells. [138] Research in this field has shown that structural modifications in anabolic steroids are critical in determining their binding affinity to ARs and their resulting anabolic and androgenic activities.

Penile cancer, or penile carcinoma, is a cancer that develops in the skin or tissues of the penis. Symptoms may include abnormal growth, an ulcer or sore on the skin of the penis, and bleeding or foul smelling discharge.
The symptoms of hypogonadotrophic hypogonadism, a subtype of hypogonadism, include late, incomplete or lack of development at puberty, and sometimes short stature or the inability to smell; in females, a lack of breasts and menstrual periods, and in males a lack of sexual development, e.g., facial hair, penis and testes enlargement, deepening ...
The medication has also been used as a topical gel to treat small penis in pre- and peripubertal boys with mild or partial androgen insensitivity syndrome. [23] [2] [24] Androstanolone was found to be effective in the treatment of advanced breast cancer in women in the 1950s, although it was used in very high doses and caused severe virilization.
