Antioxidant supplementation, effect on post‐thaw spermatozoan function in three sturgeon species
Contents 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 sper...
