reproductive system
reduced male fertility ( J:293896 )
• male mice produce fewer offspring compared with wild-type mice
decreased fertilization frequency ( J:293896 )
• spermatozoa exhibit decreased fertilization of cumulus-free oocytes compared with wild-type spermatozoa
• however, fertilization of cumulus-intact and zona pellucida-free oocytes is normal
