Dear Reich Leader!
By order of Reich Leader (Reichsleiter) Bouhler I submit to you as an enclosure a work of Dr. Horst Schumann on the influence of X-rays on human genital glands.
Previously you have asked Senior Colonel [Oberfuehrer] Brack to perform this work, and you supported it by providing the adequate material in the concentration camp Auschwitz. I point especially to the 2d part of this work, which shows that by those means a castration of males is almost impossible or requires an effort which does not pay. As I have convinced myself, operative castration requires not more than 6 to 7 minutes, and therefore can be performed more reliably and quicker than castration by X-rays.
Soon I shall be able to submit a continuation of this work to you.
Heil Hitler!
[Handwritten] Your devoted,
