| androstadienes | Derivatives of the steroid androstane having two double bonds at any site in any of the rings. (12 Dec 1998) |
| androstane | The parent hydrocarbon of the androgenic steroids. For structure, see steroids. (05 Mar 2000) |
| androstane-3,17-diol | <chemical> The unspecified form of the steroid. It has been implicated as a regulation of gonadotropin secretion. Many of its metabolites possess androgenic activity as well. Pharmacological action: anabolic steroids. Chemical name: Androstane-3,17-diol (12 Dec 1998) |

| androstanedione | 5alpha-Androstane-3,17-dione;a steroid metabolite, of which the 5b isomer is also known. (05 Mar 2000) |
| androstanes | The family of steroids from which the androgens are derived. (12 Dec 1998) |
| androstanols | Androstanes and androstane derivatives which are substituted in any position with one or more hydroxyl groups. (12 Dec 1998) |
| androstatrienes | Derivatives of the steroid androstane having three double bonds at any site in any of the rings. (12 Dec 1998) |
| androstene | Androstane with an unsaturated (i.e., -CH==CH-) bond in the molecule. (05 Mar 2000) |
| androstenediol | 5-Androsten-3b,17b-diol;a steroid metabolite differing from androstanediol by possessing a double bond between C-5 and C-6. (05 Mar 2000) |
