THE ORGANS OF REPRODUCTION 95 



is also noticeable in animals. Thus stags when 

 castrated young do not develop antlers; and even 

 if the operation is performed after the antlers have 

 appeared, the animals no longer shed them annu- 

 ally. If horns are on they fall off. This is true of 

 sheep. The cock loses its plumage, its wattles and 

 its characteristic male type of voice. 



The records of castration in the female are 

 meager. The operation is rarely performed before 

 puberty, and after this stage has been reached, the 

 changes are not so marked. This applies also to 

 domestic animals. The few experiments that have 

 been performed make it seem likely that one of 

 the functions of the female genital organs is to 

 suppress a tendency to revert to the male type; in 

 their absence the duck and pheasant, for example, 

 assume male plumage. 



In both the male and female, whether man or ani- 

 mal, castration is followed by an accumulation of 

 fat in the body, making it appear that the general 

 metabolism of the system has been disturbed. 



The results of castration can be observed in those 

 persons whose sexual organs have for one reason 

 or another not developed normally. Professor 

 Tandler refers to such "eunuchoids" as "tall, or if 

 complications are absent, at least not stunted in 

 growth; they show the typical fat distribution of 

 eunuchs. The skeletal dimensions are character- 

 ized by an especial length of extremities. There
