High Levels of Oxidation-Reduction Potential in Frozen-Thawed Human Semen Are Significantly Correlated With Poor Post-Thaw Sperm Quality

Abstract This study examined the relationship between oxidation-reduction potential (ORP) in frozen-thawed semen and the post-thaw sperm parameters. Levels of ORP were measured in 25 samples from men presenting for routine infertility work-up and were expressed as millivolt (mV)/106 sperm/ml. Frozen-thawed samples were examined for post-thaw total motility (TM%), progressive motility (PM%), total sperm count (TSC) […]
