Abstract

Background: Several studies have reported over-representation of psychiatric disorders among patients with Klinefelter' Syndrome (KS), with forensic complications.

Objective: Consider determinants of sexual assault in patient with KS.

Review: In this work, we present the case of Jules, 23 years old, with KS, benefiting from steroid replacement therapy, convicted of rape of a minor and evaluated in this context. We question here the role of his genetic pathology and of his hormonal treatment in this sexual assault.

Findings: According to evidence from the literature, it is not possible to determine with certainty the fair value of each factor and their impact on the occurrence of the sexual criminal act. Indeed, although the crime rate among KS subjects is higher than in the general population, the majority of them have never been in trouble with the law; moreover, these subjects were no more likely to commit violent sexual acts than were criminals without KS. As for hormonal treatment, it seems that testosterone is better viewed as a facilitator of initiating an aggressive response than as a primary inductor.

Conclusion: In conclusion, the onset of sexual violence that accompanied the introduction of hormonal treatment into a patient with KS suggests an effective involvement of steroid replacement therapy, even small, in the criminal act. This must incite clinicians to extreme prudence and to take account of multidisciplinary expertise (psychiatrist, endocrinologist) in order to reconsider the continuation of the treatment in this particular forensic context. Finally, we discuss other factors that can precipitate such a violent act.
