reproductive system
oligozoospermia ( J:91621 )
• the number of spermatozoa in the cauda epididymis is reduced about 50%
teratozoospermia ( J:91621 )
• abnormal flagella and sperm heads are seen
hairpin sperm flagellum ( J:91621 )
• the mutant sperm flagellum is often folded back towards the sperm head instead of being straight and elongated
• however, the composition of the mitochondrial sheath appears unaffected
abnormal sperm head morphology ( J:91621 )
• mutant sperm heads are severely malformed and abnormally oriented with respect to the flagellum
abnormal acrosome morphology ( J:91621 )
• mutant sperm heads lack a discernible well-developed acrosome
asthenozoospermia ( J:91621 )
• sperm motility is significantly decreased
abnormal spermiogenesis ( J:91621 )
• transformation of round spermatids into spermatozoa is abnormal
• regional separation of differentiation stages is disturbed
male infertility ( J:91621 )
• male, but not female, mutants are infertile
impaired sperm penetration of zona pellucida ( J:91621 )
• sperm are unable to penetrate the zona pellucida
