Of 500 patients seen because of rape, semen was identified in vaginal secretions by the identification of spermatozoa in 61%, by an acid phosphatase value of 50 units or more in 40%, and by the identification of a foreign blood group substance or a high titer of own blood group substance in 16%. The addition of the determination of the acid phosphatase to the search for spermatozoa identified semen in only 1.4% more patients, or a total of 62.4%. Identification and titers of blood group substance were confirmatory only, but further characterized the source of the semen in 25% of those patients with spermatozoa. Spermatozoa were identified for as long as 48 hours, and elevated acid phosphatase was not found after 18 hours. Acid phosphatase was elevated in only 62% of patients with spermatozoa.
在因强奸前来就诊的500名患者中，通过鉴定阴道分泌物中的精子，61%的患者被检测出精液；通过酸性磷酸酶值达到或超过50单位，40%的患者被检测出精液；通过鉴定外来血型物质或自身血型物质的高滴度，16%的患者被检测出精液。在寻找精子的同时增加酸性磷酸酶的检测，仅使多1.4%的患者检测出精液，即总共62.4%的患者检测出精液。血型物质的鉴定和滴度仅起确认作用，但在25%有精子的患者中进一步确定了精液的来源。精子可被鉴定长达48小时，18小时后未发现酸性磷酸酶升高。仅62%有精子的患者酸性磷酸酶升高。
