reproductive system
abnormal sperm head morphology ( J:350937 )
• 47% of sperm heads exhibit bluntness in the hook regions
• however, the acrosome appears normal
asthenozoospermia ( J:350937 )
• straight line velocity, curvilinear velocity, and average path velocity of spermatozoa are reduced after 10 minutes of incubation in a capacitation medium
• however, the percentage of motile spermatozoa is comparable to wild-type
reduced male fertility ( J:350937 )
• males are subfertile
• in the presence of cumulus cells and intact zona pellucida, the in vitro fertilization rate of spermatozoa is decreased
• in the absence of cumulus cells, in vitro fertilization rate of spermatozoa is decreased
• however, the decreased fertilization rate of spermatozoa is rescued by removing both cumulus cells and zona pellucida
impaired sperm penetration of zona pellucida ( J:350937 )
• the decreased fertilization rate of spermatozoa is rescued by removing both cumulus cells and zona pellucida, indicating that zona pellucida penetration is impaired
