- Description
- Reactive oxygen species (ROS) are implicated in all aspects of cellular functions. While the importance of ROS as signalling molecules is well described, ROS are also associated with stress pathologies. Within the reproduction field, there are associations with reduced fertility as a result of lipid peroxidation, protein dysfunction, premature cell death and DNA damage which readily occur in spermatozoa. These oxidative insults can arise in vivo, or in vitro as a result of sperm storage, purification and processing. Following a brief description of the production, homeostasis and functions of ROS in mammalian sperm function, this review paper will focus on describing the predominant sources of ROS in the ejaculate, the effects of ROS on a cellular and molecular level, and the actions of ROS from the whole animal perspective. There is highlighting of some studies, which have revealed the mechanisms for these observations, along with some strategies to ameliorate or prevent the instigation of the oxidative stress cascade before irreversible damage to spermatozoa occurs.
