reproductive system
• in epididymis
• synaptic failure at pachytene stage
• tubules contain only early spermatogenic cells, no post-meiotic germ cells
• increased level of apoptosis
• 3-fold lower weight
• vacuolization and seminiferous epithelium degeneration starting between P10 and P16
• between P10 and P16
• persistent double-stranded breaks at pachytene stage
• fewer homozygous mice born than expected from heterozygote interbreeding: 207:440:59 wt:het:hom

endocrine/exocrine glands
• tubules contain only early spermatogenic cells, no post-meiotic germ cells
• increased level of apoptosis
• 3-fold lower weight
• vacuolization and seminiferous epithelium degeneration starting between P10 and P16

mortality/aging
• fewer female than male mice survive: at 2 weeks female:male ratio is 32:68

cellular
• in epididymis
• persistent double-stranded breaks at pachytene stage
