renal/urinary system
N |
• no abnormalities are found in the kidney
|
reproductive system
• the few mature sperm found in the cauda epididymis showed morphological abnormalities, with less than 0.5% of total sperm being both motile and viable
|
• the flagellar membrane of the rare surviving spermatozoa found in the epididymides are usually ruptured, with the electron-dense microtubules of flagellar axonema dispersed and/or disorganized
|
• sperm counts in the testis and the cauda epididymis are significantly reduced by greater than 5-fold and greater than 20-fold, respectively
|
• there is a greater than 20-fold reduction in the number of viable sperm found in the cauda epididymis
|
• testes weight is significantly lower than controls (80 mg vs. 94 mg in wild-type males)
|
• morphological abnormalities are first observed in the elongating spermatids of stages VIII-X
• many of the spermatids prematurely detach from Sertoli cells and degenerate before sloughing off into the lumen
|
• male mice are not capable of siring offspring
|
endocrine/exocrine glands
• testes weight is significantly lower than controls (80 mg vs. 94 mg in wild-type males)
