318 THE PHYSIOLOGY OF REPRODUCTION 



Kn auer ^ h as described experiments upon rabbits in wbicb 

 he removed the ovaries from the normal position and grafted 

 them upon the mesometrium or between the fascia and the 

 muscle of the abdominal wall. He found that they could be 

 successfully implanted on both peritoneum and muscle, but 

 that some portion of the grafted ovary invariably died. The

rest, however, remained functionally active, and continued to 

 produce ova which were capable of being fertihsed. Knauer 

 states that whereas castration in female rabbits produced a 

 premature menopause, the uterus undergoing atrophy, this 

 result was prevented by a successfully transplanted ovary. 

 Knauer also experimented upon dogs and obtained similar 

 results.
