取精液分析患者的射精后尿液标本。对样本进行了精子的存在、数量和形态的检查。在171例精液中含有精子的患者中，84.8%的精液中有精子。射精后而不是射精前精子的存在及其在空洞第一部分的浓度表明，精子尿是射精后尿路冲洗的结果。Peus中的精子数量只占射出精子的一小部分，而且是可变的。PEUS与精液精子数呈显著正相关，但在少精子症和正常精子症患者中，PEUS计数有相当大的重叠。PEUS中形态正常的精子百分率反映了精液中形态正常的精子百分率。结论是，尽管PEUS反映了精液的一些特征，但单个PEUS不能作为单个患者直接精液分析的准确替代品。然而，它可以用来确定与适当的对照组相比，暴露于危险生态条件或已知会对精子发生产生不利影响的药物的人群是否减少了精子数量。
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.
