reproductive system
• decreased number of ovarian follicles
|
small ovary
(
J:195265
)
• reduced size at 45 days of age but increased number of stromal cells
|
• normal number of seminiferous tubules but diameter of tubules is 30-50% of normal
|
small testis
(
J:195265
)
• reduced testis size
|
• testicular hypoplasia but hyperplasia of interstitial cells
|
• few chiasmata found
|
• prophase I checkpoint is not triggered
• fail to form stable divalents in normal numbers
|
• chromosomes often fail to form a metaphase plate
|
• autosomal pairing is normal but defects in synapsis
• double strand breaks form normally but repair may be delayed or inefficient as inferred from persistent RAD51 foci
|
• blocked
|
• blocked
|
• normal X-Y pairing but defects in synapsis
|
• block at diakinesis of meiosis I
• apoptosis is common in spermatocytes at that point
