Androstane is a C19steroidalhydrocarbon with agonane core. Androstane can exist as either of twoisomers, known as5α-androstane and5β-androstane.

• 
  5α-Androstane
• 
  5β-Androstane

5α-Androstane is reported to be effective as anandrogen, in spite of having nooxygen containingfunctional groups.^[1][2]

Androstanes are steroid derivatives with carbons present at positions 1 through 19.
