The invention relates to biomarkers associated with fertility, and methods of uses thereof. The invention describes sperm proteins associated with fertility and methods for evaluating a mammalian sperm sample. Preferred aspects relates to evaluating the fertility of bulls by measuring in spermatozoa the amount of one or more proteins selected from AK1, PEBP1, CCT5, CCT8, ELSPBP1, PSMA6 and BSP1. Also described are methods for assigning a fertility index to a mammalian semen sample, methods for enhancing the fertility of a mammalian semen sample and semen extenders for increasing fertility of mammalian spermatozoa. |
