N normal phenotype

Annulus and mitochondrial disruption in Slirptm1.2Pjle/Slirptm1.2Pjle sperm

mortality/aging
• number of homozygous pups is at lower than the expected Mendelian ratio at weaning

reproductive system
N
• normal sperm production and normal testis weight
• abnormal gap at the mid-piece/annulus junction
• less defined mitochondrial cisternae and the mitochondrial matrix appears more electron dense
• significant decrease in progressive motility but no significant difference in total sperm motility
• sire smaller litters when crossed to wild-type females(average litter size 4.5 pups compared to 6.9 pups for wild-type males)
