Researchers in sexual health and behaviour, National Institute of Mental Health and Charles University, Czech Republic

Kateřina Klapilová & Lucie Krejčová

Mgr. Kateřina Klapilová, Ph.D. (ECPS), and Mgr. Lucie Krejčová, Ph.D., are researchers at the Center for Sexual Health and Interventions at the National Institute of Mental Health and Charles University in the Czech Republic. Their research focus on sexual health and human sexual behaviour. Their work spans large-scale national studies of sexual behaviour and health, as well as experimental and psychophysiological research on sexual reactivity, preferences, and dysfunctions. They contribute to the development and evaluation of preventive and intervention programs targeting problematic and paraphilic sexual behaviour, and are involved in advancing evidence-based approaches to the prevention of sexually motivated crime, alongside educational initiatives for professionals in the field.

Revolutionizing the research, assessment, and treatment of paraphilic disorders: the role of virtual reality and artificial intelligence

Paraphilic disorders represent a heterogeneous group of conditions in which atypical sexual interests may cause distress, functional impairment, or harm to others. Despite decades of clinical and forensic work, significant gaps remain in their assessment, treatment, and prevention. Traditional approaches are constrained by methodological, ethical, and legal limits, while many at-risk individuals remain undetected and difficult to engage.
Emerging technologies offer ways to address these challenges. Artificial intelligence (AI) enables the creation of legally compliant, standardized, and demographically tailored visual stimuli for psychophysiological testing (e.g., penile plethysmography).
Projects such as the Philippe-Pinel virtual character generator and recent Czech initiatives with AI-generated static and dynamic stimuli—including nonverbal behavioral cues—improve ecological validity while respecting legal boundaries. Virtual reality (VR) adds immersive environments that support individualized risk assessment, treatment monitoring, and the development of “training arenas,” where patients can safely rehearse strategies and clinicians can observe change. Early feasibility studies in forensic psychiatry suggest benefits in anger regulation, impulsivity, and behavioral control.

Digital tools also show promise for prevention and outreach. Chatbots and avatars have been piloted as deterrence and redirection tools, for instance the reThink chatbot on Pornhub UK, which was associated with reduced CSAM searches and increased contacts with support services. Online CBT programs (e.g., Prevent It) and pilot motivational interviewing courses further illustrate how digital platforms can engage non-disclosing individuals, CSAM users, and incarcerated populations. Together, AI and VR innovations herald a transformative future for sexology, providing ethically sound, ecologically valid, and scalable tools for assessment, intervention, and prevention.
