reproductive system
asthenozoospermia ( J:98301 )
• significant alterations in sperm velocities, amplitude, and forward movement indicating decreased sperm motility compared to wild-type, however did not observe reduced migration of sperm in the female genital tract
• greater decrease in sperm motility than in triple homozygous Tnp2/Hist1h1t/Mcsp mice
reduced male fertility ( J:98301 )
• litter size was sharply reduced when mutant males were mated to wild-type females
impaired fertilization ( J:98301 )
• only 8%-15% of wild-type oocytes were fertilized by mutant sperm (compared to 84.8% by wild-type sperm), but 71-75% of the fertilized oocytes developed into normal blastocysts (compared to 61.5% of the controls)
impaired binding of sperm to zona pellucida ( J:98301 )
• reduced binding of sperm to zona pellucida from wild-type females
