Nine hundred and sixteen men who had undergone bilateral vasectomy were followed up with semen analysis at monthly intervals. After an average of 10 ejaculations at least 35% of men still had non-motile sperms at the end of the first month. This persisted in four men even after 50 ejaculations or more. The reasons for, and the implication of the very slow clearance of spermatozoa after vasectomy are discussed.
916名接受双侧输精管结扎术的男性接受了每月一次的精液分析随访。平均射精10次后，至少35%的男性在第一个月末仍有不活动精子。即使在射精50次或更多次后，仍有4名男性存在这种情况。本文讨论了输精管结扎术后精子清除非常缓慢的原因及其影响。
