Antioxidant supplementation, effect on post-thaw spermatozoon function ...
Abstract: High levels of reactive oxygen species (ROS), which may be associated with reduced sperm quality, can be detected during cryopreservation of sperm of some species. Our objective was to investigate whether the addition of antioxidants to cryopreservation extenders influenced post-thaw sperm characteristics and fertility in Acipenser dabry anus,Acipenser sinensis and Acipenser baerii.
