debated causes of PCOS is oxidative stress (OS) ( Murri et al. 2013 , Desai et al. 2014 ). However, it has not been established whether oxygen stress affects the development of PCOS or whether it is only a secondary disorder resulting from

control this process and considers the current means by which post-ovulatory ageing can be prevented or delayed. Specifically, in light of recent research, we revisit the proposal that oxidative stress may act as the ‘trigger’ for a cascade of other events

presence of oxidative stress and hypoxia is especially important in the placenta because they facilitate development by promoting angiogenesis, proliferation, and differentiation ( Pringle et al. 2010 , Chiarello et al. 2020 ). In contrast, excessive
