Seminal fructose, citric acid and acid phosphatase were estimated from 23 healthy males before vasectomy and three months later. Each subject had children and the men volunteered for sterilization because other possibilities of contraception were inapplicable. Vasectomy was performed under local anesthesia in the conventional manner. Semen of all patients was azoospermic three months after vasectomy. In this study, the amounts of seminal fructose and citric acid were significantly higher after vasectomy than before operation. The activity of seminal acid phosphatase was a little less, but the difference was not significant. The increase of seminal fructose and citric acid could be explained by the lack of spermatozoa, which normally use them into their metabolism.
对23名健康男性在输精管结扎术前及术后三个月测定了精液中的果糖、柠檬酸和酸性磷酸酶。每位受试者都有子女，这些男性因其他避孕方法不适用而自愿接受绝育。输精管结扎术采用常规方式在局部麻醉下进行。所有患者在输精管结扎术后三个月精液中无精子。在本研究中，输精管结扎术后精液中的果糖和柠檬酸含量显著高于手术前。精液酸性磷酸酶的活性略有降低，但差异不显著。精液中果糖和柠檬酸的增加可以用缺乏精子来解释，精子通常会将它们用于自身代谢。
