mortality/aging
early reproductive senescence ( J:85108 )
• females exhibited premature reproductive senescence

reproductive system
decreased germ cell number ( J:85108 )
• observed in both 129S6/SvEvTac and C57BL/6 genetic backgrounds, however a more severe depletion was observed in the C57BL/6 background
seminiferous tubule degeneration ( J:85108 )
• ~3% were severely degenerated, on a 129S6/SvEvTac genetic background
small testis ( J:85108 )
• ~2-fold smaller than those of heterozygotes on a 129S6/SvEvTac coisogenic background
early reproductive senescence ( J:85108 )
• females exhibited premature reproductive senescence
abnormal spermatogenesis ( J:85108 )
• a proportion of spermatocytes progressed through spermatogenesis to produce functional spermatozoa
abnormal male meiosis ( J:85108 )
• elevated frequency of mispaired meiotic chromosomes
reduced female fertility ( J:85108 )
• putatively due to a diminished population of primordial germ cells during migration into the genital ridge
• male fertility was not impaired
