Evaluation of Lipid Membrane Peroxidation, Mitochondrial Membrane Potential and Oxidative Stress on Bull Semen Frozen with Reduced Sperm Number after Colloidal Single Layer Centrifugation

Sperm quality assays have increased in number in the last 10 years. Most of these assays are flow cytometry based in application and are modified from assays that have been developed to measure somatic cell function. The goal of any sperm quality assay should be to advance the clinicians/researchers understanding of sperm cell function and the relationship to fertility. While these assays appear to measure somatic cell-like functions in sperm there tends to be little understanding how the results of these assays relate to fertility.
