• lack appreciable levels of round and elongated postmeiotic spermatids

azoospermia
(
J:216246
)
• epididymides are devoid of mature spermatozoa
|
• about 20% of tubules contain multiple apoptotic cells
|
• most tubules are highly vacuolized
|
small testis
(
J:216246
)
• severe reduction in size
|
• severe reduction in weight
• weight is similar to controls at P14 but reduced by 3 weeks of age
• weigh only 30% of wild-type at 8 weeks of age
|
• arrest at the late pachytene stage
|
• absence of markers for post-meiotic cells indicates a block in male meiosis
• no diplotene or later stages of meiosis are seen indicating a failure to progress beyond the pachytene stage of meiosis
|
• males, but not females, are infertile
|
endocrine/exocrine glands
