Levels of ORP were measured in 25 samples from men presenting for routine infertility work-up and were expressed as millivolt (mV)\/10<sup>6<\/sup>&nbsp;sperm\/ml. Frozen-thawed samples were examined for post-thaw total motility (TM%), progressive motility (PM%), total sperm count (TSC) and ORP. The cryo-survival rate (CSR) was calculated as post-thaw TM\/pre-freeze TM \u00d7 100. Data are provided as median and interquartile range (25th and 75th percentiles). The post-thaw TM% (10.0% [4.00%, 15.1%]), PM% (5.88% [2.97%, 9.33%]) and TSC (12.5 [10.0, 17.5] \u00d7 10<sup>6<\/sup>&nbsp;sperm) were significantly lower than the pre-freeze TM% (45.9% [32.9%, 59.1%], PM% (31.5% [24.4%, 40.0%] and TSC (120 [90, 250] \u00d710<sup>6<\/sup>&nbsp;sperm) (p &lt; .001). Post-thaw ORP (2.62 [2.52, 3.13] mV\/10<sup>6<\/sup>&nbsp;sperm\/ml) was significantly higher than pre-freeze ORP (0.73 [0.54, 1.21] mV\/10<sup>6<\/sup>&nbsp;sperm\/ml; p &lt; .001). The CSR was 21.7% (11.3%, 31.9%). The post-thaw seminal ORP was negatively correlated with post-thaw TM% (r = -.5; p = .02), PM% (r = -.41; p = .03), TSC (r = -.60; p = .03) and CSR (r = -.52; p = .01). Increased levels of ORP are significantly correlated with poor post-thaw sperm quality and CSR.<\/p>\n","protected":false},"template":"","tags":[72],"producto":[92],"revista":[103],"class_list":["post-3425","publicacion","type-publicacion","status-publish","hentry","tag-mioxsys","producto-mioxsys","revista-first-international-journal-of-andrology"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.8 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>High Levels of Oxidation-Reduction Potential in Frozen-Thawed Human Semen Are Significantly Correlated With Poor Post-Thaw Sperm Quality - Fertil Ib\u00e9rica<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/fertiliberica.es\/publicacion-cientifica\/high-levels-of-oxidation-reduction-potential-in-frozen-thawed-human-semen-are-significantly-correlated-with-poor-post-thaw-sperm-quality\/\" \/>\n<meta property=\"og:locale\" content=\"pt_PT\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"High Levels of Oxidation-Reduction Potential in Frozen-Thawed Human Semen Are Significantly Correlated With Poor Post-Thaw Sperm Quality - Fertil Ib\u00e9rica\" \/>\n<meta property=\"og:description\" content=\"Abstract This study examined the relationship between oxidation-reduction potential (ORP) in frozen-thawed semen and the post-thaw sperm parameters.
