The effects of 4 antiandrogens and stilboestrol on the cytosol receptor of the rat ventral prostate have been compared. Equimolar doses of cyproterone acetate, chlormadinone acetate, SC 9022 and flutamide inhibited the binding of dihydrotestosterone to the receptor complex in vivo by 44 to 50% whereas stilboestrol had no effect. In the in vitro studies an equimolar concentration produced similar effects to those observed in vivo with the exception of flutamide which had no effect. This technique provides a method for assessing and comparing the effectiveness of antiandrogens on the androgen receptor complex of the prostate.
