摘要
目的:探讨年龄和pH值对精子质量相关指标的影响。方法:2020—2021年来本院进行精液常规检测者1246例(不包括无精子症者)为研究对象,根据年龄分为≤30岁组、31-35岁组、≥36岁组,以精子活力及运动参数作为精子质量研究指标,观察不同年龄组和精液pH值组精子活力及运动参数。结果:不同年龄组精子总活力[运动活跃型精子(PR)+非运动活跃型精子(NP)]、PR、路径速度(VAP)、直线速度(VSL)、曲线速度(VCL)、直线精子活力均有差异(P<0.01),且随年龄增长各指标均下降。精液pH值与NP呈现负相关关系(r=-0.064,P<0.05)。精液pH 7.2时PR+NP、PR、VCL最高;精液pH 8.0时VAP和VSL最高,NP最低。结论:精子活力、运动参数随年龄增长而降低,并且在精液pH 7.2-8.0时最好。
Objective:To explore the influence of age and semen pH value of adult males on their sperm quality indicators.Methods:A total of 1246 adult males(excluding azoospermia)who came to hospital for semen routine detections from 2020 to 2021 were selected as the research objects.According to the age,these males were divided into three groups,which included the males with aged≤30 years in group A,the males with aged 31-35 years in group B,and the males with aged≥36 years in group C.Sperm motility and kinematic parameters were selected as the indicators of sperm quality,and which of the males with different age and with different semen pH were observed.Results:The values of progressive sperm(PR),total sperm motility(PR+non-progressive sperm(NP)),velocity of average path(VAP),velocity of straight-line(VSL),velocity of curve line(VCL),and straight-line sperm motility of the males had significantly difference among group A,B,and C(P<0.01),and which of the males had decreased with their age increase.There was a significant negative correlation between the semen pH value of the males and their NP value(r=-0.064,P<0.05).The values of PR+NP,PR,and VCL of the males with the semen pH value of 7.2 were the highest.The values of VAP and VSL of the males with the semen pH value of 8.0 were the highest,but the NP value of the males with the semen pH value of 8.0 was the lowest.Conclusion:The sperm motility and kinematic parameters of the adult males decrease with their age increase,and which are the best when their semen pH values of the males are 7.2-8.0.
