Abstract

OBJECTIVE

To evaluate the relationship between sperm motility parameters and sperm morphology.

METHODS

Seven hundred and eighty-three semen samples were tested. Sperm motility parameters were analyzed by computer-aided sperm analysis (CASA) , and sperm morphology assessed by automated sperm morphology analyzer (ASMA). The cases were classified based on the World Health Organization criteria. Morphologically 241 of the samples were normal and the other 542 abnormal.

RESULTS

VCL, WOB, VAP of the morphologically abnormal group were significantly higher than those of the normal group (P < 0.05, P < 0.001), while MAD, LIN, STR of the abnormal group were significantly lower (P < 0.05, P < 0.001). There were significant positive correlations between the morphologically normal sperm rates and MAD, LIN, WOB, STR, and a significant negative correlation between the morphologically normal sperm rate and ALH.

CONCLUSION

Morphological abnormality of sperm is often accompanied with weak motility, which is probably attributed more to some factors that coact on both sperm motility and morphology than to the influence of sperm morphological abnormality on sperm motility.

摘要

目的

评估精子活力参数与精子形态之间的关系。

方法

对783份精液样本进行检测。精子活力参数采用计算机辅助精子分析（CASA）进行分析，精子形态通过自动精子形态分析仪（ASMA）进行评估。病例根据世界卫生组织标准进行分类。形态学上，241份样本正常，另外542份异常。

结果

形态异常组的曲线速度（VCL）、直线性（WOB）、平均路径速度（VAP）显著高于正常组（P < 0.05，P < 0.001），而形态异常组的平均角位移（MAD）、线性度（LIN）、摆动性（STR）显著低于正常组（P < 0.05，P < 0.001）。形态正常精子率与MAD、LIN、WOB、STR之间存在显著正相关，与平均侧摆幅度（ALH）之间存在显著负相关。
