Studies on the distribution patterns of certain components in split ejaculates provide information on the origin of seminal constituents in the reproductive tract. In this regard, a simple fractionation method of whole ejaculates has been developed. Human ejaculates after collecting as a whole, were almost equally divided into five fractions through liquefaction known vesicular, prostatic and testicular components were measured in these subsequently liquefied fractions. Levels of vesicular components increased while that of prostatic components decreased gradually and significantly in the subsequent fractions. This change pattern agrees well with that of the fractions in split ejaculates. But the change pattern for spermatozoal concentration was statistically invalid. The bases of these observations have been discussed. The results suggest that studies on the distribution patterns of seminal components in the parts separated during gradual liquefaction can give preliminary ideas about their origin in the reproductive tract like split ejaculation technique.
对分段射精中某些成分分布模式的研究提供了有关生殖道中精液成分来源的信息。在这方面，已开发出一种简单的全精液分级方法。收集后的人类全精液经液化后几乎平均分为五个部分，随后在这些液化部分中测量已知的精囊、前列腺和睾丸成分。在随后的部分中，精囊成分水平升高，而前列腺成分水平逐渐且显著下降。这种变化模式与分段射精中各部分的变化模式非常吻合。但精子浓度的变化模式在统计学上是无效的。已对这些观察结果的依据进行了讨论。结果表明，对逐渐液化过程中分离出的部分精液成分分布模式的研究可以像分段射精技术一样，对其在生殖道中的起源给出初步概念。
