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.
In general, androgens such as testosterone promote protein synthesis and thus growth of tissues with androgen receptors. [16] Testosterone can be described as having anabolic and androgenic effects, though these categorical descriptions are somewhat arbitrary, as there is a great deal of mutual overlap between them. [17]
As an anabolic (metabolism-related) hormone, testosterone plays a vital role in building and maintaining muscle mass. Studies show men with low testosterone levels experience muscle loss and ...
However, these progestins are testosterone derivatives and do have significant androgenic/anabolic activity, sometimes producing acne and other mild androgenic effects in women. Conversely, in men, these drugs may actually have functional antiandrogen effects due to their potent progestogenic and hence antigonadotropic activity and capacity to ...
Elevated androgen levels caused by use of androgen supplements can inhibit production of LH and block production of endogenous androgens by Leydig cells. Without the locally high levels of androgens in testes due to androgen production by Leydig cells, the seminiferous tubules can degenerate, resulting in infertility.
Women with complete androgen insensitivity syndrome (CAIS), who have a non-functional androgen receptor (AR) and are immune to the androgenic effects of DHEA and other androgens, have absent or only sparse/scanty pubic and axillary hair and body hair in general, demonstrating the role of DHEA and other androgens in body hair development at both ...
In particular, the oral route is subject to a high first-pass effect, which results in high levels of testosterone in the liver and consequent hepatic androgenic effects, as well as low potency due to first-pass metabolism in the intestines and liver into metabolites like dihydrotestosterone and androgen conjugates.
