From: Post-thaw ATP supplementation enhances cryoprotective effect of iodixanol in rat spermatozoa
The effect of OptiPrep™ on cooled rat sperm motility. The effect of OptiPrep™ on cooled rat sperm motility was evaluated using total and progressive motility (a) and VAP (b) 1 and 3 h after initiation of cooling to 4 °C with different concentrations of OptiPrep™ of rat spermatozoa. *P < 0.05 v.s. 1 h after cooling within same iodixanol treatment groups. n = 6
