 The objective of this study is to evaluate the performance of the MiOXSYS System as it measures sORP in semen samples with various degrees of semen quality. The MiOXSYS System is comprised of the MiOXSYS Analyzer and disposable, single-use MiOXSYS Sensors. Thirty microliters 30 uL of neat semen is required for each test. sORP results from each semen sample will be compared to their corresponding results on the WHO semen analysis parameters 5th Edition Laboratory Manual for the Examination and Processing of Human Semen 2010, which is the current methods for assessing semen quality.
