INTRODUCTION.: The present study investigates the relevance of genital abnormalities (GA) like cryptorchidism, hypospadias, and phimosis usually diagnosed in early childhood for the development of psychosexual problems and deficits in a sample of N = 163 convicted sexual homicide perpetrators. AIMS.: The first aim was to investigate the prevalence of early childhood GA in a sample of sexual homicide perpetrators. The second was to explore differences in the psychosexual development of participants with GA in early childhood compared with those without GA. It was expected that offenders with GA show specific problems in their psychosexual development compared with offenders without GA. METHODS.: The data for the present study were obtained by reanalyzing an existing database derived from a large-scale research project about sexual homicide. Using a predominantly exploratory design we, therefore, divided the total sample into two subgroups (with vs. without indicators of GA). MAIN OUTCOME MEASURES.: Main outcome measures were the number of sexual homicide perpetrators showing GA in early childhood and the differences of subjects with and without GA with regard to their psychosexual development (i.e., according to sexual deviant interests or sexual dysfunctions). RESULTS.: The prevalence of GA is substantially higher in this sample than epidemiological studies indicated in the normal population. This result provided first support for the importance of GA in the population of sexual homicide perpetrators. Further analyses indicate significant differences between both subgroups: Offenders with GA in early childhood showed indicators for more sexual dysfunctions (e.g., erectile dysfunction) in adulthood and a distinct tendency of more masochistic sexual interests. CONCLUSION.: Even if the exploratory design of the present investigation allows no causal conclusions between GA and sexual homicide offenses, the result provided support for the relevance of early childhood sexual diseases in the assessment (and treatment) of offenders who have committed severe sexual violence.
本研究调查了生殖器官异常（GA）如隐睾、尿道下裂和包茎在早期儿童中通常被诊断出的情况，对于性犯罪者样本中心理性别问题和缺陷的发展的相关性。目的：第一个目的是调查性犯罪者样本中早期儿童 GA 的患病率。第二个目的是探索早期儿童有 GA 与无 GA 的参与者之间的心理性别发展差异。预计与无 GA 的罪犯相比，有 GA 的罪犯在心理性别发展方面会表现出特定的问题。方法：本研究的数据是通过重新分析一个关于性犯罪的大型研究项目的现有数据库获得的。我们使用主要的探索性设计，因此将总样本分为两个亚组（有 GA 与无 GA）。主要结果测量：主要结果测量是早期儿童有 GA 的性犯罪者人数，以及有 GA 与无 GA 的受试者在心理性别发展方面的差异（即根据性偏离兴趣或性功能障碍）。结果：GA 的患病率在该样本中显著高于流行病学研究在正常人群中所表明的患病率。这一结果首次为 GA 在性犯罪者人群中的重要性提供了支持。进一步的分析表明，两个亚组之间存在显著差异：早期儿童有 GA 的罪犯在成年后表现出更多的性功能障碍（如勃起功能障碍）的指标，并且有明显的倾向于更多的受虐性兴趣。结论：即使本研究的探索性设计不允许在 GA 和性犯罪之间做出因果结论，但这一结果为在评估（和治疗）犯下严重性暴力罪行的罪犯时，早期儿童性疾病的相关性提供了支持。
