Telomere length in bovine sperm is related to the production of reactive oxygen species, but not to reproductive performance

Abstract excerpt

Over the last decades, selection in cattle has mainly been based on milk production rather than on reproductive efficiency. While, when applied, focus on reproduction has involved females, attention has barely been paid to males and, if so, it has only looked at classical sperm quality parameters. In effect, variables such as telomere length have been missed, despite the fact that longer telomeres have been...
