* Testosterone derivatives: direct derivatives of testosterone not falling into the groups below
* 4,5α-Reduced/dihydrogenated testosterone derivatives: dihydrotestosterone
Dihydrotestosterone (DHT, 5α-dihydrotestosterone, 5α-DHT, androstanolone or stanolone) is an endogenous androgen sex steroid and hormone. The enzyme 5α-reductase catalyzes the formation of DHT from testosterone in certain tissues includ ...

* 19-Demethylated testosterone derivatives: 19-nortestosterone (nandrolone) derivatives
* 17α-Alkylated testosterone derivatives: methyltestosterone and ethyltestosterone derivatives

Vinyltestosterone (also known as 17α-vinyltestosterone, 17α-vinylandrost-4-en-17β-ol-3-one, and 17α-hydroxypregna-4,20-dien-3-one) is a synthetic anabolic–androgenic steroid (AAS) that was never marketed. However, two 19-nortestosterone der ...

The last group consists of progestins with mostly only very weak androgenic/anabolic activity.

Commentary
17α-Ethynylated testosterone derivatives are potent progestins with only very weak androgenic/anabolic activity and are used as oral contraceptives or for the treatment of gynecological conditions in women. They are invariably classified as progestins rather than as AAS. 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 functionalantiandrogen
