Abstract

Cryopreservation induces sublethal damage to the spermatozoa, which leads to their reduced fertile life. The objective of this study was to investigate the effect of taurine, hypotaurine and trehalose as antioxidants on the function of the freezing-thawed sperm in Korean Jeju Black Bull. The semen...
