Effect of time on oxidation-reduction potential in semen and seminal plasma Academic Article uri icon


  • Objective Oxidation-reduction potential (ORP) is a novel measure of oxidative stress or redox imbalance in biological fluids. Reactive oxygen species (ROS) are highly reactive and have a very short half-life. ROS levels in the seminal ejaculate should be measured within an hour after collection to prevent a reduction in ROS levels over time. The traditional methods of measuring seminal ROS are time sensitive and time consuming, making it difficult to use them for diagnostic purposes. It would be highly advantageous to employ a method that is independent of semen age and provides results in real time. The objective was to assess the effect of time on static ORP (sORP), which provides a snapshot of current redox balance, and capacity ORP (cORP) which is indicative of the amount of antioxidant reserves available. Design Prospective study measuring ORP in semen and seminal …
