- W2046886868 abstract "OBJECTIVE: Levels of ROS <250 relative light units (RLU)/sec/X 10 sperm (RLU) seen in our lab for healthy men appear to be physiological. We compared semen parameters, total antioxidant level (TAC) and DNA fragmentation in infertile men with seminal ROS >250 to those men with ROS <250. DESIGN: Prospective clinical study. MATERIALS AND METHODS: ROS, TAC and sperm DNA fragmentation were measured in seminal ejaculates of 101 infertile men. ROS/TAC score was derived by principal components. Patients were divided into group 1: ROS <250 and group 2: ROS >250 RLU. RESULTS: Semen parameters, TAC, DNA fragmentation and ROS/TAC score in infertile men with low vs. high seminal ROS are shown in the table.TableGroup 1 (56.4%)Group 2 (43.6%)Variable(n = 57)(n = 44)P valueOR (95%CI)Sperm concentration47.9 (19.4-105.9)13.5 (4.8-35.5)0.0020.85 (0.76-0.94)aOdds ratios of high ROS are relative to increases in the variable of 10 units.(X 10mL)Sperm motility (%)66.5 (48-78.8)43 (19.5-66.3)0.0020.77 (0.65-0.91)aOdds ratios of high ROS are relative to increases in the variable of 10 units.Leukocytospermia0 (0-0)0 (0-0.8)0.0044.69 (1.64-13.4)bOdds ratios of high ROS are relative to increases in the variable of positive result.(X 10/mL)(12% positive)(40% positive)TAC (micromoles Trolox equivalent)2010 (1530-2560)1844 (1566-2336)0.430.88 (0.64-1.21)cOdds ratios of high ROS are relative to increases in the variable of 500 units.TUNEL+ (%)17.1 (9.6-32.7)28.3 (12.5-48.2)0.0361.25 (1.01-1.53)aOdds ratios of high ROS are relative to increases in the variable of 10 units.ROS-TAC score54.7 (50.5-59.4)41.4 (39.7-46.0)>0.0010.07 (0.03-0.21)aOdds ratios of high ROS are relative to increases in the variable of 10 units.OR = odds ratio; 95% CI = 95% confidence interval; Values are median and (25th - 75th percentiles), P-values by logistic regression.a Odds ratios of high ROS are relative to increases in the variable of 10 units.b Odds ratios of high ROS are relative to increases in the variable of positive result.c Odds ratios of high ROS are relative to increases in the variable of 500 units.

CONCLUSIONS: Infertile men with higher seminal ROS levels also have higher sperm DNA fragmentation. Patients with high ROS levels should be evaluated for DNA damage." @default.
