title: [Effect of steroids with anti-androgenic properties on the androgenic and myotrophic activity of testosterone and its various derivatives].
abstract: Experiments were conducted on castrated male rats. The effect of antiandrogen 17,17-dimethyl-18-norandrostadien-4,13-one-3 on the androgenic and myotrophic activity of testosterone and of some of its modified analogues, preparations with anabolic action, was studied. The intensity of the antihormonal effects depended not only on the antiandrogen dose used, but also on the dose of the agonist preparation. The author suggests a modification of the method used to assess the biological action of antiandrogens, consisting in a single administration of the "anabolic" preparation with a prolonged action and a 7-day administration of antiandrogen to castrated animals.
