A study was carried out to evaluate the andrological parameters in 540 human semen specimens divided into groups according to sperm counts. The parameters were: motility percentage and grade, percentage of viability and of morphologically normal sperm and immature cells. The Duncan multiple range test and the Kruskal-Wallis test with multiple comparison of ranks were used in the statistical analyses. Of particular interest, among other our findings, were the significant differences obtained by comparing the group with sperm counts up to 5 x 10(6) per ml semen and that with counts ranging from 5.1 to 10 x 10(6) per ml semen. This was true for all parameters with the exception of semen volume. Comparison of the oligozoospermic groups (up to 20 x 10(6)/ml) with those having higher sperm counts also showed significant differences. There was a trend towards improvement of the examined parameters with the increase in sperm density, but with a remarkable heterogeneity particularly within the oligozoospermic groups. In all groups motility, viability and morphological normality of sperm showed a positive correlation with each other. "Normal values" of the parameters studied could be derived from scatterplot charts over the entire range of sperm counts and from the statistical evaluation of the grouped material.
开展了一项研究，以评估540份人类精液标本的男性生殖参数，这些标本根据精子计数分为不同组。参数包括：活力百分比和等级、存活率百分比、形态正常精子和未成熟细胞的百分比。统计分析采用邓肯多重极差检验和带有秩次多重比较的克鲁斯卡尔 - 沃利斯检验。在我们的其他研究结果中，特别值得关注的是，将每毫升精液精子计数高达5×10⁶的组与每毫升精液计数在5.1至10×10⁶之间的组进行比较时，除精液体积外，所有参数均存在显著差异。少精子症组（每毫升精液精子计数高达20×10⁶）与精子计数较高的组进行比较时也显示出显著差异。随着精子密度的增加，所检查的参数有改善的趋势，但特别是在少精子症组内存在明显的异质性。在所有组中，精子的活力、存活率和形态正常性之间均呈正相关。所研究参数的“正常值”可从整个精子计数范围内的散点图以及分组材料的统计评估中得出。
