A case of complete testicular feminization (Morris syndrome) in a male pseudohermaphrodite is described. The results of the hormone analyses and the histological features of the resected gonad are presented. The literature is reviewed with special reference to whether gonadectomy should be performed in the pre or post-pubertal period. We advocate early castration because of the high incidence of germ cell neoplasia and the possibility of virilization in case of incomplete androgenic resistance. Our approach is based on the satisfactory feminization achieved by exogenous estrogen therapy.
