reproductive system
immotile sperm ( J:338084 )
• spermatozoa are immotile and spermatozoa incubated in a capacitating medium exhibit a severe decrease in overall motility
small seminiferous tubules ( J:338084 )
• lumen of seminiferous tubules is on average smaller than wild-type tubules
small testis ( J:338084 )
• the testis to body weight ratio is reduced
abnormal spermatogenesis ( J:338084 )
• defects in spermatogenesis, with impaired nuclear condensation
• seminiferous tubules show impaired production of spermatids
abnormal sperm flagellum morphology ( J:338084 )
• sperm flagella show deformities
abnormal sperm axoneme morphology ( J:338084 )
• sperm flagella show disrupted axonemes
abnormal sperm midpiece morphology ( J:338084 )
• mature spermatozoa show disorganized mitochondria sequestered in cytoplasmic droplets
• sperm flagella show incomplete midpieces
abnormal sperm head morphology ( J:338084 )
• 100% of spermatozoa have abnormal head shapes
abnormal acrosome assembly ( J:338084 )
• abnormal acrosome biogenesis with lack of acrosomal cap formation
globozoospermia ( J:338084 )
• spermatozoa have round, granular heads, instead of the hook-like shape
absent acrosome ( J:338084 )
• sperm heads have no acrosomal cap
detached acrosome ( J:338084 )
• spermatozoa show abnormal dissociation of the acrosome and the granule during cap biogenesis in the testis
abnormal sperm nucleus morphology ( J:338084 )
• sperm heads have misshapen nuclei
abnormal spermiogenesis ( J:338084 )
• spermatozoa show abnormal dissociation of the acrosome and the granule during cap biogenesis in the testis
• the testicular form of SPACA1 in round spermatids is aberrantly retained indicating abnormal sperm maturation
male infertility ( J:338084 )
• males are sterile despite the formation of copulatory plugs

endocrine/exocrine glands
small seminiferous tubules ( J:338084 )
