论证。作为受害者或犯罪者生物特征的一部分，性别鉴定在法医调查中起着重要的作用，并可以使成功查明身份的数量增加50%。在之前发表的研究中，更多关注指纹在性别鉴定中的作用，而手掌印至今为止受到的关注较少。

该研究的目的是估计手掌印脊的密度，并使用特定人群（埃及人）的性别参数制定一个鉴定性别的方程式。

材料与方法。该研究涉及来自埃及开罗市的200名相当健康的年轻人（113名男性和87名女性，年龄在18-22岁）。手掌印是通过颜料方法而取得的，然后确定手掌印每四个区域掌纹脊的密度。

结果。女性手掌所有区域的脊密度均高于男性，双手所有区域的统计差异较高 （p <0.001 ）。右手掌辨别能力最明显的区域为第四（P4），左侧为第一（P1）。同时，我们能够确定性别，准确率为70%。同时，我们能够以高达70%的准确率确定性别。

结论。研究结果表明，在法医学中使用手掌印作为确定性别的工具是可行的，可以将可疑病例的数量减少50%。
