[Reducing oxidative DNA damage by adding antioxidants in human semen samples undergoing cryopreservation procedure].
To evaluate the protective effects of oxidative DNA damage by adding antioxidants: ascorbate, catalase (CAT), and superoxide dismutase (SOD) in human semen samples undergoing cryopreservation procedure. ⋯ Supplementation of ascorbate or CAT reduces the level of ROS that induces sperm nuclear DNA damage, and improves the human sperm quality in the process of freeze-thawing.
