OTHER GENITAL ORGANS 



In this section I shall consider certain structures, 

 or organs, that play important roles in regard to the 

 reproductive functions. We shall see that, with the 

 exception of the testicles, it is hardly likely that they 

 are organs of internal secretion in the strict sense ; but 

 because various writers, even to-day, regard them as 

 hormonopoietic organs it is necessary briefly to consider 

 their status in this respect. And, in the first place, 

 I would again emphasize the fact that, while every cell 

 in the body has internal secretory functions in regard 

 to itself, these do not justify us in placing individual 

 cells in the same category as the thyroid and the rest 

 of the indubitable regulators of metabolism in general. 



UTERUS 



The uterus Some years ago I expressed the opinion, on certain 



secretion™* 1 theoretical grounds, that the uterus might be an organ 

 forming an internal secretion, and this secretion I called 

 1 uterin ' 1 ; and Bond 2 described experiments which 

 showed, he thought, that the uterine secretion influences 

 the growth of the corpus luteum. 



At a later date, Fellner 3 conducted experiments the 

 results of which led him, also, to assume that the uterus 

 elaborates an internal secretion. 



Moreover, Ancel and Bouin 4 believe that in rabbits
