Post-ejaculatory urine samples ( PEUS ) were obtained from patients undergoing semen analysis. The samples were examined for the presence, number and morphology of sperm. Spermatozoa were found in PEUS of 84.8% of 171 patients whose semen contained sperm. The presence of sperm after, but not before, ejaculation and their concentration in the first part of the void indicated the spermaturia to be the result of urethral washing after ejaculation. The number of sperm in PEUS was a small and variable fraction of the ejaculated sperm. A significant positive correlation was found between the PEUS and the semen sperm count, but there was a considerable overlap of PEUS counts between oligospermic and normospermic individuals. The percentage of sperm with normal morphology in PEUS reflected that in semen. It is concluded that although PEUS reflects some of the semen characteristics, a single PEUS cannot serve as a precise substitute for a direct semen analysis in the individual patient. It can, however, be used for establishing whether populations exposed to dangerous ecological conditions or to drugs which are known to adversely affect spermatogenesis, have reduced sperm count by comparison to appropriate control groups.
射精后尿液样本（PEUS）取自接受精液分析的患者。对样本进行精子的存在情况、数量和形态检查。在精液中含有精子的171例患者中，84.8%的患者的PEUS中发现了精子。射精后而非射精前存在精子以及其在排尿第一部分中的浓度表明，血尿是射精后尿道冲洗的结果。PEUS中的精子数量是射出精子数量的一小部分且变化不定。PEUS与精液精子计数之间存在显著正相关，但少精子症患者和正常精子症患者的PEUS计数有相当大的重叠。PEUS中形态正常的精子百分比反映了精液中的情况。结论是，虽然PEUS反映了一些精液特征，但单个PEUS不能作为个体患者直接精液分析的精确替代方法。然而，它可用于确定暴露于危险生态条件或已知对精子发生有不利影响的药物的人群与适当对照组相比精子计数是否减少。
