A method for the evaluation of the local antiandrogenic action of 5α-reductase inhibitors on human skin

Abstract
A method was developed for the 1st time that allows the evaluation of the effect of therapeutic concentrations of 5.alpha.-reductase inhibitors [progesterone] in human skin without applying radioactivity to the skin. The method makes it possible to determine whether inhibition is found only at the application site or in other parts of the skin.
