In total, 847 patients, except for azoospermic patients were investigated. At the time of each patient＇s first consultation, semen parameters were measured using SMASTM or CellSoft 3000TM, and production of reactive oxygen species was measured using a computer-driven LKB Wallac Luminometer 1251 Analyzer. The patients were divided into two groups： reactive oxygen species - positive and negative. The semen parameters within each group were measured using one of the two computer-assisted semen analyzer systems and then compared. Correlations between reactive oxygen species levels and sperm motion parameters in semen from the reactive oxygen species - positive group were also investigated. Reactive oxygen species were detected in semen samples of 282 cases （33.3%）. Sperm concentration （P 〈 0.01; P 〈 0.01）, motility （P 〈 0.01; P 〈 0.05）, and progressive motility （P 〈 0.01; P 〈 0.01） were markedly lower in the reactive oxygen species - positive group than in the reactive oxygen species - negative group. Among the sperm motion parameters in the reactive oxygen species - positive group, sperm concentration （P 〈 0.01; P 〈 0.01）, motility （P 〈 0.05; P 〈 0.01）, mALH （P 〈 0.05; P 〈 0.01）, and progressive motility （P 〈 0.05; P 〈 0.01） also showed inverse correlations with the logarithmic transformed reactive oxygen species levels. Therefore, this study demonstrated that excessive reactive oxygen species in semen damage sperm concentration, motility, and other sperm motion parameters.展开更多
