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.
Testosterone is the primary androgen — or male hormone — in your body. ... Other research shows that hypogonadism is associated with a testicular volume ... Anabolic steroids used to increase ...
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 ...
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]
Androgens are the precursors to estrogens in both men and women. In addition to their role as natural hormones, androgens are used as medications; for information on androgens as medications, see the androgen replacement therapy and anabolic steroid articles.
Steroid ring system. This is a list of androgens/anabolic steroids (AAS) or testosterone derivatives. Esters are mostly not included in this list; for esters, see here instead. The major classes of testosterone derivatives include the following (as well as combinations thereof):
Androgens: oxandrolone, oxabolone, nandrolone (also known as anabolic-androgenic steroids or simply anabolic steroids) Oestrogens: diethylstilbestrol (DES) and ethinyl estradiol (EE) Progestins: norethisterone, medroxyprogesterone acetate, hydroxyprogesterone caproate. Some steroid antagonists: Androgen: cyproterone acetate
An androgen prohormone, or proandrogen, is a prohormone (or prodrug) of an anabolic-androgenic steroid (AAS). They can be prohormones of testosterone or of synthetic AAS, for example, nandrolone (19-nortestosterone). Dehydroepiandrosterone (DHEA), DHEA sulfate (DHEA-S), and androstenedione may all be considered proandrogens of testosterone. [1]
