Abstract

Rat oral mucosa microsomal Δ<superscript>4</superscript>-3-ketosteroid-5α-A-ring reductase enzyme system, reducing testosterone and 4-androstenedione, was found to be inducible by systemic administration of medroxyprogesterone acetate (MPA). MPA, when used in a mixture with testosterone and/or 4-androstenedione in vitro, acted as a competitive inhibitor of the reduction of these substrates. [ABSTRACT FROM AUTHOR]
