Abstract: Oxidative stress is involved in the defect of embryo development, reactive oxygen species (ROS) can originate from embryo metabolism or embryo surroundings. Some exogenous factors can improve the production of ROS and cause embryo developmental arrest, it seriously limits embryos related studies. There are many mechanisms to protect embryos against ROS, therefore, it is essential to combine with ROS resources and anti-oxidative mechanisms at different developmental phase, in order to improve the inner anti-oxidative efforts, control culture conditions and in practical operation but it is a complex problem to defend oxidative damage during embryo culture, and complete culture system, decrease the induction effects of outer factors on ROS, produce in vitro embryos effectively.

Key words: embryos; ROS; sources; anti-oxidative mechanisms
