Abstract
IT HAS been shown that appreciable regression of human prostatic and mammary neoplasms occurs in some cases after bilateral adrenalectomy (Huggins and Bergenstal, 1951; 1952) with the use of cortisone acetate as maintenance substitution therapy. Since these tumors are neoplasms which are known to be influenced by sex hormones, it became important to know whether cortisone acetate had androgenic or estrogenic effects and if this compound could modify significantly the physiologic action of sex hormones on the accessory sex structures. These experiments will demonstrate that cortisone acetate does not stimulate the canine prostate nor the uterus of the rat but inhibits partially the action of diethylstilbestrol on the uterus.
Kochakian (1944) found that the implantation of a pellet of cortisone in castrate male mice did not cause growth of the accessory reproductive structures. The administration of cortisone acetate to intact male rats did not greatly modify the histological
