tubules are absorbed in the testis proper, or are carried to the 

 epididymis where they are absorbed along with the greater part 

 of the spermatozoa which were present at the time the testis 

 was elevated to the abdominal cavity. 



4. Absorption of the germinal epithelium from a cryptorchid 

 testis into the blood stream does not affect the integrity of the 

 scrotally-retained normal testis. 



5. Spermatozoa will remain alive in the germinal passages of 

 the guinea pig for longer than nine days. Following their loss 

 of motility they rapidly lose their tendency to clump, but 

 degeneration of mature spermatozoa takes place slowly, and 

 especially so in the ductus deferens. It has been determined 

 that a given spermatozoon in the male genital passages though 

 retaining its capacity for motility for nine days, may retain its 

 morphological identity for over 100 days. 



6. Venous stasis through ligature of the internal spermatic 

 vein of testes allowed to remain in the scrotum does not produce 

 the degeneration complex seen in testes retained in the abdominal 

 cavity.
