In vitro-produced embryos are less viable than their in vivo counterparts. It is known that the developmental speed is a reliable marker of embryo viability. One of the major factors impairing in vitro embryo development is oxidative stress. The aim of the study was to evaluate oxidative stress and lipid peroxidation in bovine in vitro-produced embryos that reached different developmental stages at the end of culture. Abattoir-derived oocytes were matured in vitro in TCM-199 with 15% bovine serum, 0.5mugmL(-1) of FSH, 5mugmL(-1) of LH, 0.8mM L-glutamine and 50mgmL(-1) of gentamicin. Mature cumulus-oocyte complexes (COC) were fertilized in Tyrode's modified medium, supplemented by 5.3 SImL(-1) of heparin, 30muM penicillamine, 15muM hypotauri...
