Oxidative stress differentially impacts male and female bovine embryos depending on the culture medium and the stress condition

Male and female embryos are known to differ for their metabolism and response to environmental factors very early in development. The present study aimed to evaluate the response to oxidative stress of male and female bovine embryos at the morula-blastocyst stages in terms of developmental rates, total cell number and apoptotic rates in two culture conditions. Embryos where cultured in a medium supplemented with either 5% fetal calf serum (FCS) or 4  mg/mL bovine serum albumin and a mixture of insulin, transferrin and selenium (BSA-ITS).
