To examine the amount of variability in semen analysis results and whether there is any effect of season, 673 specimens provided by seven normal, healthy men (61-205 specimens/subject) over 72-324 weeks were assessed for sperm concentration, ejaculate volume, motility and motility index. Noticeable sample to sample variations were found. The largest proportion of the overall variance was due to within-subject differences, e.g., sperm concentration (54%), ejaculate volume (59%), percentage motility (96%) and motility index (74%). Although changes in semen-analysis results occurred over the year, no consistent trend was seen. No evidence was found to suggest that the differences were due to modifications of the methods employed by the laboratory, or to the change of season.
为了研究精液分析结果的变异性以及季节是否有任何影响，对7名正常健康男性（每人提供61 - 205份样本）在72 - 324周内提供的673份样本进行了精子浓度、射精量、活力和活力指数的评估。发现样本之间存在明显差异。总体方差的最大比例归因于个体内部差异，例如精子浓度（54%）、射精量（59%）、活力百分比（96%）和活力指数（74%）。尽管精液分析结果在一年中有所变化，但未观察到一致的趋势。没有证据表明这些差异是由于实验室采用的方法改变或季节变化所致。
