摘要: 背景 氧化应激和能量代谢是影响男/雄性个体精子质量的重要因素。但现有研究多为动物实验,缺少人群证据,并且以往研究多侧重于探究氧化应激和能量代谢对精子密度和活动力的影响,缺乏对精子运动速度和运动轨迹等男性生殖健康客观指标的具体参数的研究。目的 研究氧化应激和能量代谢相关生物学指标与男性精子密度、活动力、运动速度和运动轨迹等各参数之间的关系,为男性生殖健康的精准干预提供流行病学证据。方法 2021年6—12月在空军军医大学西京医院生殖医学中心招募109例志愿者作为研究对象,采集其精液样本,并应用计算机辅助精子分析系统(CASA)检测精子密度参数(精子密度、直线运动精子密度)、精子活动力参数〔精子总活力、前向运动率(PR)、非前向运动率(NP)〕、精子运动速度参数〔曲线速度(VCL)、直线速度(VSL)、平均路径速度(VAP)〕和精子运动轨迹参数〔平均侧摆幅值(ALH)、平均鞭打频率(BCF)、平均移动角度(MAD)、运动的直线性(LIN)、运动的摆动性(WOB)、运动的前向性(STR)〕。检测精液样本中丙二醛(MDA)、还原型谷胱甘肽(GSH)反映氧化应激水平,检测三磷酸腺苷(ATP)的水平评估能量代谢水平。应用一般线性模型(GLM)评估氧化应激指标和能量代谢指标与精子质量各参数之间的相关性。结果 共有67份精子样本用于检测氧化应激水平,42份精子样本用于评估能量代谢水平。GLM分析表明,氧化应激水平方面,MDA水平与直线运动精子密度、精子总活力、PR、NP、VCL、VSL、VAP、ALH、BCF、MAD、LIN、WOB、STR呈负相关(P<0.05);GSH水平与直线运动精子密度、精子总活力、PR、VSL、VAP,ALH、BCF、MAD、LIN、WOB、STR呈正相关(P<0.05)。能量代谢水平方面,ATP水平与直线运动精子密度、精子总活力、PR、NP、VCL、VSL、VAP,ALH、BCF、MAD、LIN、WOB、STR呈正相关(P<0.05)。结论 较高的氧化应激水平与精子活动力降低、精子运动速度减慢以及运动轨迹发生不利改变有关,而较高的ATP水平与男性精子活动力升高、运动速度加快以及运动轨迹发生有利改变有关。

Abstract:

Background

Oxidative stress and energy metabolism are important factors that affect sperm quality in male individuals. However, the majority of available studies are based on animal models, and evidence from human studies is still inadequate. Besides, most previous studies have paid more attention to the effects of oxidative stress and energy metabolism on sperm concentration and motility, with a little focus on their impact on sperm motility velocity and trajectory and other specific objective indicators evaluating the state of male infertility.

Objective

To investigate the effects of biological indicators related to oxidative stress and energy metabolism on sperm concentration, motility, movement velocity and trajectory in male adults, thus to provide epidemiological evidence for precise intervention of male reproductive health problems.

Methods

One hundred and nine volunteers were recruited as subjects from the Center of Reproductive Medicine in Xijing Hospital, Air Force Medical University from June to December 2021. Their semen samples were collected. The computer-assisted sperm analysis system was applied to detect sperm concentration parameters (sperm concentration, linear motion sperm concentration), sperm motility〔total sperm motility, progressive motility (PR), non-progressive motility (NP) 〕, sperm motility velocity parameters〔curvilinear velocity (VCL), straight-line velocity (VSL), average path velocity (VAP) 〕 and sperm motility trajectory parameters 〔mean amplitude of lateral head displacement (ALH), mean beat-cross frequency (BCF), mean angular displacement (MAD), linearity coefficient (LIN), wobble coefficient (WOB), straightness coefficient (STR) 〕. Besides that, the levels of malondialdehyde (MDA) and reduced glutathione (GSH) in semen samples were measured as oxidative stress markers, and the level of sperm adenosine triphosphate (ATP) was measured to assess the level of energy metabolism. General linear model (GLM) was used to evaluate the correlation of MDA and GSH and ATP with sperm quality parameters.

Results

A total of 67 sperm samples were used to examine oxidative stress level, and 42 sperm samples were employed to assess the level of energy metabolism. The analysis using the GLM demonstrated that in terms of oxidative stress level, MDA level was negatively correlated with linear motion sperm concentration, total sperm motility, PR, NP, VCL, VSL, VAP, ALH, BCF, MAD, LIN, WOB, and STR (P<0.05) ; the level of GSH was positively correlated with linear motion sperm concentration, total sperm motility, PR, VSL, VAP, ALH, BCF, MAD, LIN, WOB, and STR (P<0.05). In terms of energy metabolism, the level of ATP was positively correlated with linear motion sperm concentration, total sperm motility, PR, NP, VCL, VSL, VAP, ALH, BCF, MAD, LIN, WOB, and STR (P<0.05) .

Conclusion

Higher level of oxidative stress is associated with lower sperm motility, lower velocity of sperm movements, and the adverse change in sperm trajectory. While higher ATP level is related to higher sperm motility, higher sperm movement velocity, and the favorable change of sperm trajectory.
