reproductive system
• 24% of cauda epididymis spermatozoa exhibited abnormal sperm head morphology due to acrosome malformation
• however, chromatin condensation in the sperm nucleus appeared normal
|
• 30% of acrosomes in epididymal sperm appeared indented and/or partially detached from the nuclear envelope
• similar abnormal acrosomes were observed in spermatids within the testis
|
• many acrosomes were not attached to the nuclear envelope
|
• reduced migration of sperm from the uterus to the oviduct was noted
|
• all homozygous males were infertile
|
• sperm have an impaired ability to penetrate the zona pellucida and fertilize oocytes
