About this study

The purpose of this study is to determine if elevations in oxidative stress, as measured by oxidation-reduction potential (ORP), can distinguish between semen samples from men with abnormal semen parameters from those with normal semen parameters. Static ORP (sORP) results, measured by the MiOXSYS System- a novel technology, will be compared to the current World Health Organization (WHO) semen analysis parameters.
