Abstract
This study determined: the effects of α-tocopherol on apoptotic and necrotic levels of cumulus cells after in vitro maturation of bovine oocytes; whether exposure to α-tocopherol facilitates the development of bovine enclosed oocytes to metaphase II; and the effects of this antioxidant on apoptotic and necrotic levels of granulosa cells cultured in vitro. In conclusion, supplementation with α-tocopherol on in vitro maturation of bovine oocytes has a detrimental effect on the ability of oocytes to reach metaphase II, increasing the number of apoptotic and necrotic cumulus cells of bovine cumulus oocyte complexes (COC). This antioxidant showed a slight improvement in the viability of cultured granulosa cells at a concentration of 100 µM. Key words: Bovine, oocyte maturation in vitro, antioxidant, α-tocopherol
