STERILITY AND THE ENDOCRINES 251 
spite of this fact endocrine stimulation produced re- 
sults. Last but not least, the psychological effect pro- 
duced by the renewing or revitalizing of a dormant 
function was capable in these five cases of so changing 
the outlook on life that bodily vigor and mental activity 
were substituted for morbid forebodings. 
The question of grafting or implanting testes is a 
satisfactory procedure in the majority of cases, but as 
sex dysfunction is pluriglandular in its entirety, it is 
necessary to ascertain the metabolic rate and function 
quotient of the other secretory glands before operative 
procedure is advised. In a testicular implant case in 
which operation was performed some time ago, it was 
necessary to resort to thyroid feeding after the implan- 
tation in order to co-ordinate the vis a tergo of the 
secretory equilibrium, the patient being myxedematous 
as well as suffering from hypogonadism. 
I am now working with a solution composed of the 
salts of the blood, the concentration being isotonic with 
the blood serum, into which the gland of the donor is 
placed to facilitate its state of resistance, during the 
interim between removal and implantation. By this 
method the functioning power of the gland may be kept 
infa highly nourished state. The spermatogenic func- 
tion of the testes is not endogenous, but pluriglandular 
in its sequence. In other words, sex dysfunction, or 
testicular dysfunction, is hypoendocrinism, rather than 
hypogonadism.
