• despite their reduced epididymal size and sperm count, male mice produce normal litter sizes when mated with wild-type females and are technically fertile
• in vitro, cauda epididymal sperm show small but significant reductions in total, progressive, and hyperactive motility and increased local (twitching, nonprogressive) motility before capacitation
• after capacitation, sperm show normal total and hyperactive motility, a slight increase in progressive motility, and a small reduction in local motility, suggesting that differences in motility parameters are relatively minor
• later stages of spermatogenesis are negatively impacted
• at 7-8 weeks of age, epididymal sperm count is significantly lower than that in wild-type males
• males show a high frequency of morphological defects in cauda epididymal sperm
• incorrect head-to-neck connections are commonly observed
• club-shaped and triangular head morphologies and incorrect head-to-neck connections are commonly observed
• abnormal sperm head structures are observed during spermiogenesis
• in vitro capacitated sperm show slight alterations in the pattern of capacitation-induced protein tyrosine phosphorylation, with decreased abundance of several minor phosphoproteins
• at 7-8 weeks of age, epididymal weight is significantly lower than that in wild-type males
• however, testis weight is normal
• following in vitro capacitation, the rate of A23187-induced acrosome reaction in cauda epididymal sperm is significantly lower than that in wild-type sperm
• however, in the absence of induction, sperm show the same low frequency of spontaneous acrosome reactions as wild-type sperm
• an in vivo competitive artificial insemination trial showed that the average % of embryos produced per female by mutant epididymal sperm is about one-sixth of that produced by wild-type sperm (14.4% versus 85.6%), indicating impaired sperm fertilizing capacity
• in an IVF assay, sperm show a significantly reduced ability to penetrate the zona pellucida than wild-type sperm, resulting in a lower frequency of sperm retained in the perivitelline space or fused with the ooplasm
