reproductive system
oligozoospermia ( J:108395 )
• the number of sperm in the semen was approximately 0.01% of wild-type
teratozoospermia ( J:108395 )
• almost all sperm from mutant mice showed abnormal morphologies, such as large round heads, short tails, and multiple tails
multiflagellated sperm ( J:108395 )
• multiple sperm tails
short sperm flagellum ( J:108395 )
• short sperm tails
globozoospermia ( J:108395 )
