• despite abnormal sperm motility, male mice exhibit normal fertility
hairpin sperm flagellum ( J:148050 )
• mutant sperm frequently exhibit flagellar bending (typically up to 180 degrees) at the annulus at the junction of the midpiece and the principal piece
asthenozoospermia ( J:148050 )
• the percentage of motile spermatozoa is reduced compared to in wild-type mice
• sperm exhibit defective flagellar beat pattern and lack of forward progression unlike wild-type sperm
