reproductive system

abnormal sperm principal piece morphology ( J:352416 )

♂ • sperm with attenuated principal piece

♂ • however, no obvious abnormalities in manchette structure of spermatids

abnormal sperm fibrous sheath morphology ( J:352416 )

♂ • 54% of sperm show fiber sheath abnormalities in the flagella

♂ • the fibrous sheath is either unrecognizable or partially lost

kinked sperm flagellum ( J:352416 )

♂ • approximately 25% of sperm exhibit bent tails

short sperm flagellum ( J:352416 )

♂ • approximately 33% of sperm exhibit short tails

oligozoospermia ( J:352416 )

♂ • mice exhibit diminished sperm count

decreased sperm progressive motility ( J:352416 )
