Roles of reactive oxygen species in the regulation of luteal function

Ephemerality and prolongation of luteal function have been matters of great concern in reproduction for many years. However, their control mechanisms are very complex and differ among mammals. Recently, evidence has indicated that reactive oxygen species may play important roles in the regulation of luteal function. Reactive oxygen species are present in most somatic cells and are involved in apoptosis, or 'physiological cell death'. In the corpus luteum, reactive oxygen species also exert luteolytic effects as well as some paradoxical luteotrophic effects. This paper discusses the possible roles of reactive oxygen species in the control of luteal function.
