N normal phenotype
reproductive system
• mice exhibit a 3-fold higher number of sperm with marked angulation of the tails
• spermatozoon forward motility is half that of wild-type counterparts
• cytoplasmic droplets are associated with angulations of the sperm tails, suggesting final maturation of the spermatozoa fails
• male mice sire litters that are half that in number compared to litters produced by wild-type males
