摘　　要：目的研究精浆氧化还原电位(ORP)和归一化氧化还原电位(nORP)与精子DNA碎片指数(DFI)、高DNA着色性(HDS)及运动参数的相关性,探讨其是否能作为评估男性生育潜能的生物标志物。方法选取2023年10月至12月于中国人民解放军北部战区总医院生殖医学科男科门诊就诊的309例男性作为研究对象。采用电极法检测精浆ORP、nORP,分析其与DFI、HDS、年龄、禁欲时间、精液量、精子总数、精子浓度、前向运动精子数、前向运动精子百分率、非前向精子数、非前向精子百分率、不动精子数、不动精子百分率、精子活动率、曲线速度(VCL)、直线速度(VSL)、平均速度(VAP)、线性指数(LIN)、直性指数(STR)及振动指数(WOB)的相关性;对nORP结果进行三等分,比较其与上述参数的差异。采用广义线性回归探讨nORP与HDS的关系,同时生成HDS与nORP的平滑曲线拟合。结果Pearson相关性及Spearman相关性分析显示,ORP和nORP均与精液量、不动精子百分率及DFI呈正相关,与前向运动精子数、前向运动精子百分率、精子活动率、VSL、VAP呈负相关(P<0.05);不同的是ORP还与禁欲时间、不动精子数呈正相关(P<0.05),与LIN、STR及WOB呈负相关(P<0.05),而nORP还与HDS呈正相关(P<0.05),与精子总数、精子浓度、非前向精子数、非前向精子百分率、不动精子数、VCL呈负相关(P<0.05)。nORP分组结果显示,精液量、精子总数、精子浓度、前向运动精子数、前向运动精子百分率、非前向精子数、非前向精子百分率、不动精子数、不动精子百分率、精子活动率、VCL、VSL、VAP、DFI、HDS组间比较差异有统计学意义(P<0.05);将nORP与HDS制作曲线拟合,对年龄及禁欲时间进行了调整。随着HDS的增加,nORP呈线性上升趋势。结论ORP、nORP都与精子DFI和主要运动参数相关,但nORP还与代表精子成熟度的HDS相关,更能反映精液质量,可作为评估男性生育潜能的生物�Objective To investigate the correlation between seminal plasma oxidation-reduction potential(ORP)and normalized ORP(nORP)with sperm DNA fragmentation index(DFI),high DNA staining(HDS),and motility parameters,and to explore whether these parameters can be used as biomarkers for evaluating male fertility potential.Methods A total of 309 men who attended the andrology clinic at the Department of Reproductive Medicine,General Hospital of Northern Theater Command,between October 2023 and December 2023,were selected in this study.We analyzed the correlation between seminal plasma ORP and nORP and parameters such as DFI using the electrode method,HDS,age,days of abstinence,semen volume,total sperm count,sperm concentration,sperm motility(forward motile sperm count,forward motile sperm percentage,non-forward sperm count,non-forward sperm percentage,immotile sperm count,immotile sperm percentage,and sperm motility rate),and motility indices(curvilinear velocity[VCL],straight-line velocity[VSL],average velocity[VAP],linear index[LIN],straightness index[STR],and wobble coefficient[WOB]).The nORP results were divided into three groups and analyzed in relation to each of the parameters mentioned above.A generalized linear regression model was used to assess the relationship between nORP and HDS,with smooth curve fitting performed to visualize this relationship.Results Pearson and Spearman correlation analyses revealed that both ORP and nORP were positively correlated with semen volume,percentage of immotile sperm,and DFI,but negatively correlated with forward motile sperm count,percentage of forward motile sperm,sperm motility rate,VSL,and VAP(P<0.05).Additionally,ORP was positively correlated with abstinence days and immotile sperm count(P<0.05)and negatively correlated with LIN,STR,and WOB(P<0.05).However,nORP was positively correlated with HDS(P<0.05),and negatively correlated with total sperm count,sperm concentration,non-forward sperm count,non-forward sperm percentage,immotile sperm count,and VCL(P<0.05).The nORP group
