Androstane is a C19 steroid with a gonane core. Androstane can exist as either of two isomers, known as 5α-androstane and 5β-androstane.

5α-Androstane

5β-Androstane

Synthetic androgens and anabolic steroids are androstane derivatives.

Some progestins, such as ethisterone and dimethisterone, are also androstane derivatives.
