The analysis of condom traces has recently been added to the standard forensic examination protocol of sexual assault and rape cases. Several recent studies have thus focussed on the detection of condom components and classification of the chemical profiles using statistics, obtaining very promising results. The purpose of the present article is to critically review the literature regarding condom chemical analysis. A large analytical panel of both destructive and non-destructive methods has been proposed for the analysis of condom traces, each offering completely different analysis type and thus complementary information. However, few studies have considered these traces within a human matrix, which is necessary to establish an accessible protocol for forensic laboratories to allow this type of analysis. Additionally, issues remain concerning reproducibility, sensitivity, and the validation of analytical parameters. Considering that the demand for condom residue analysis is increasing, there is a definite need for further research on the forensic analysis of condom traces in order to offer quality services to the criminal justice system.
近年来，避孕套痕迹分析已被纳入性侵犯和强奸案件的标准法医检查协议中。因此，最近有几项研究集中在使用统计学方法检测避孕套成分和分类化学特征上，取得了非常有前景的结果。本文旨在批判性地回顾有关避孕套化学分析的文献。已经提出了一个大型的分析面板，包括破坏性和非破坏性方法，用于分析避孕套痕迹，每种方法都提供了完全不同的分析类型，因此提供了互补的信息。然而，很少有研究考虑到这些痕迹在人类基质中的存在，这对于建立法医实验室可访问的协议以允许进行这种类型的分析是必要的。此外，在可重复性、灵敏度和分析参数的验证方面仍存在问题。考虑到对避孕套残留物分析的需求不断增加，确实需要对避孕套痕迹的法医分析进行进一步研究，以便为刑事司法系统提供优质服务。
