Abstract:

Oxidative stress caused by elevated reactive oxygen species (ROS) is one of the predominant causes of both male and female infertility.Oxidative stress conditions cause either cell death or senescence by oxidation of cellular molecules including nucleic acid,proteins,and lipids.It is particularly important to minimize oxidative stress when in vitro fertilization is performed for the purpose of assisted reproduction.On the other hand,the beneficial roles of ROS,such as intracellular signaling,have become evident.The antithetical functions of ROS make it more difficult to overcome the problems caused by oxidative stress.This paper summarizes the research progress of the mechanism of action of ROS in oogenesis and in the process of embryonic development.
