Abstract: There was a relatively stable reactive oxygen species (ROS) generation and scavenging system in the stallion semen. The stable system would be destructed when seminal was removed after centrifugation. Freezing and thawing process would not be effective removal of ROS, which would lead to the thawed sperm of various physiological functions, which directly affected the quality of frozen semen, by adding exogenous antioxidants could re-enable the semen of ROS generation and scavenging to achieve balance. This paper reviewed the ROS production system by stallion spermatoza and leukocyte, and ROS scavenge system by GSH-PX, CAT, SOD, VA, VE, and designed to provide some help to the people who studied stallion semen cryopreservation of sperm by ROS injury research.

Key words: stallion semen; free radicals; production; scavenge; system
