The sperm motility characteristics of 140 men (percentage motile and average velocity of all sperm in motion; percentage progressive and the average velocity of sperm swimming more than 15 microns/sec) were determined using a laser-Doppler technique and correlated with other aspects of sperm quality, including the concentration and the proportion of abnormal and dead sperm in the ejaculate. In addition, the influence of the length of the period of abstinence, the viscosity of seminal plasma and the volume of the ejaculate were also assessed. The four motility characteristics were all highly correlated with each other. The magnitude of all four parameters increased in an exponential fashion with increasing sperm number up to 400 x 10(6) per ejaculate. At higher numbers, no further improvement in motility was observed. Moreover, increasing sperm number was associated with a decline in the proportion of sperm exhibiting abnormalities in morphology but with an increase in viable sperm 30 min after ejaculation. The relative viscosity of the ejaculates had generally no influence on sperm motility. In contrast, certain of the sperm motility characteristics, including the average velocity, were significantly negatively correlated with the length of the abstinence period.
采用激光多普勒技术测定了140名男性的精子活力特征（活动精子的百分比和所有活动精子的平均速度；进行性运动精子的百分比和游动速度超过15微米/秒的精子的平均速度），并将其与精子质量的其他方面进行关联，包括精液中精子的浓度、异常精子和死精子的比例。此外，还评估了禁欲时间长短、精浆粘度和射精量的影响。这四种活力特征彼此之间都高度相关。随着每次射精精子数量增加至400×10⁶，所有四个参数的数值均呈指数方式增加。精子数量更高时，未观察到活力有进一步改善。此外，精子数量增加与形态异常精子比例下降相关，但与射精后30分钟时活精子数量增加相关。射精液的相对粘度通常对精子活力没有影响。相比之下，某些精子活力特征，包括平均速度，与禁欲时间长短呈显著负相关。
