The enzymatic activities of aminotransferases AST and ALT have been measured in the semen of a group of 98 subjects undergoing fertility studies, correlated with spermatic density and motility. An AST/ALT ratio was obtained for all patients. The results indicate that there exists a correlation between both enzymes' activities and spermatic density and motility. In two cases of excretory azoospermia, an elevated AST/ALT relation was obtained, while in two cases f secretory azoospermia a low AST/ALT ratio was seen. Aminotransferase values can thus be considered a useful piece of data in the evaluation of seminal quality, and the AST/ALT ratio used more specifically in te discrimination of the various types of azoospermia.
在一组98名接受生育能力研究的受试者的精液中，检测了转氨酶AST和ALT的酶活性，并将其与精子密度和活力进行了关联。计算了所有患者的AST/ALT比值。结果表明，这两种酶的活性与精子密度和活力之间存在相关性。在两例排泄性无精子症患者中，AST/ALT比值升高，而在两例分泌性无精子症患者中，AST/ALT比值较低。因此，转氨酶值可被视为评估精液质量的有用数据，而AST/ALT比值更具体地用于区分各种类型的无精子症。
