The subject of undescended testis has been of great interest to one of us (J. S. E.) for over twenty years. In previous publications we have reported our results of operative treatment. Our point of view has changed somewhat and has been broadened by the work of other surgeons in this field and by our own increased experience. In this communication we are concerned chiefly with the newer methods of treatment now in vogue— the attempt to bring undescended testes into their proper position in the scrotum by the use of hormones. Those in which we are interested are the gonadotropic hormones derived from the anterior lobe of the pituitary gland and similarly acting water-soluble substances derived from the urine of pregnant women.
The literature during the past five or six years has been replete with reports of brilliant results by this mode of therapy. Some of the reports are
