A simple technique for the identification of the different spermatogenetic stages of Onchocerca volvulus is described. It is practicable for large-scale examinations in the field. The reproductivity of male worm populations can be assessed and directly correlated with the corresponding female worm populations. The activity of male filariae decreases with the increasing age of the worm population. Only few male worms transmit spermatozoa during mating, but spermatogenesis is continous also in very old male individuals. These old male filariae store high numbers of spermatozoa and cease their migration between the nodules.
本文描述了一种用于鉴定盘尾丝虫不同生精阶段的简单技术。该技术适用于野外大规模检查。可以评估雄虫群体的繁殖力，并将其与相应的雌虫群体直接关联。雄丝虫的活性随着虫群年龄的增加而降低。只有少数雄虫在交配时传递精子，但在非常老龄的雄虫个体中精子发生也是持续的。这些老龄雄丝虫储存大量精子，并停止在结节之间的迁移。
