Attenuation of cryopreservation-induced oxidative stress by antioxidant: Impact of Coenzyme Q on the quality of post-thawed buck spermatozoa.

The aim of this study was to determine the quality of post-thawed buck spermatozoa by attenuation of cryopreservation-induced oxidative stress using CoQ, a lipophilic antioxidant. Ejaculates at every sampling period were collected from four Mahabadi bucks, pooled and diluted in soybean lecithin-based extenders containing 0 (negative control, NC), 0.5 (CQ0.
