• N: normal phenotype

reproductive system

abnormal sperm flagellum morphology ( J:376129 )

♂ • sperm tails show curved and irregular morphology

♂ • sperm flagella show partially absent inner dynein arms but have the typical 9+2 axonemal structure and peri-axonemal structures

decreased sperm progressive motility ( J:376129 )

♂

asthenozoospermia ( J:376129 )

♂ • sperm motility, progressive motility, and swimming velocity are lower than in wild-type sperm

reduced male fertility ( J:376129 )

♂ • males show severely disrupted fertility

♂ • however, no differences in testicular size or testis/body weight ratio are seen and presence of spermatogenic cells are seen at different stages in the testes
