Abstract

X-ray microanalysis of human sperm cells in donor semen having a range of motilities from 0% to 85% showed that elemental composition is not strongly correlated with spermatozoal motility. Only copper in the midpiece was positively correlated with motility when high- and low-fertility groups were compared. Aging of cells in semen caused large changes in subcellular elemental concentrations as motility decreased, notably with uptake of zinc, but these changes were not reflected in the range of motilities in the clinical samples. Electrolyte balance as measured by sodium to potassium ratios also appeared not to be correlated with motility. Subcellular elemental distribution is not a major factor in determining sperm motility in normal human semen.

摘要

对供体精液中活力范围为0%至85%的人类精子细胞进行的X射线微分析表明，元素组成与精子活力没有很强的相关性。当比较高生育力和低生育力组时，只有中段的铜与活力呈正相关。随着精液中细胞老化，活力下降，亚细胞元素浓度发生了很大变化，尤其是锌的摄取，但这些变化并未反映在临床样本的活力范围内。通过钠钾比测量的电解质平衡似乎也与活力无关。亚细胞元素分布不是决定正常人类精液中精子活力的主要因素。
