202 THE INTERNAL SECRETIONS 1920 



velous. His eyes brightened, his countenance became 

 animated, his mentation was accelerated, and he took 

 on a temporary vigor that was phenomenal, but as fleet- 

 ing as a drink of whiskey. The sex glands immediately 

 became the subject of the keenest investigation, and it 

 was found that they have the greatest degree of auton- 

 omy. There is virtually no dependence whatever upon 

 the central nervous system ; for it was found that ani- 

 mals may conceive, and give birth to their young and 

 suckle them, with their spinal cords severed. The ova- 

 ries may be removed from the pelvis, and tucked away 

 in the axilla, without arresting menstruation, save for 

 a month or two. The effect of the sexual glands on the 

 body development and other glands of internal secre- 

 tion is marvelous. For centuries it has been known 

 that the castration of an animal increased its fat, and 

 this operation has been employed by animal breeders 

 for commercial purposes. 



The influence of the sex glands is stimulating to the 

 thyroid, and when this stimulus is removed, the les- 

 sened activity of the thyroid lowers oxidation and fat 

 accumulates in the tissues. It is for this reason that 

 many individuals take on flesh from 45 to 50. It is an 

 indication of what has been termed "hypogonadism," 

 the testicles or ovaries are degenerating. 



In the treatment of obesity, which can safely and 

 surely be remedied by the administration of thyroid ex- 

 tract, the effectiveness of this medication is greatly 

 enhanced by the addition of an extract of the corre- 

 sponding sex gland. On the other hand, the pituitary 

 (anterior) has a stimulating effect on the testicles; 

 for when the greater part of this gland is removed, the 

 testicles atrophy in a very short time. 1 Hence, in all 

 conditions, where an increased action of the testicle is 

 desired, combine pituitary with your spermin medica- 

 tion, and you will increase the effectiveness of your 

 treatment.
