Penile plethysmography
Koudelková, Zuzana ; Harabiš, Vratislav (referee) ; Hrozek, Jan (advisor)
This bachelor´s thesis focuses on methods that examine volumetric changes of genital organs (especially for volume changes in male sexual limb). These changes are used in the sex diagnosis. The most common type of examination is to determine sexual preference of the patient. The aim of this work is to describe how have been the changes investigated previously and how they are investigating in the routine practice now. Find out which are their limits. Try to build a new type of sensor which could help to better evaluate the volume changes. And try to create a program in LabVIEW environment in which the measured data is displayed and stored.

: Sexual reactivity of teleiophilic and pedophilic men to audio stimuli (a replication study)
Vagenknecht, Václav ; Klapilová, Kateřina (advisor) ; Weiss, Petr (referee)
The assessment of pedophilic sexual preferences is an important part of forensic and research practice. Standardization of methods and stimuli used across sites is missing, making data transferability and comparability more difficult. The aim of this study was to investigate if the stimuli used in the USA and Canada are able to reliably distinguish between pedophilic and control subjects in the Czech Republic, based on their elicited sexual arousal. A stimuli set was first translated into Czech and voice recordings were created for the narratives. Sexual arousal was measured using circumferential penile plethysmography. 29 pedophilic (15 heterosexual; 14 homosexual) and 26 control (12 heterosexual; 12 homosexual) participants took part in the study. The sample comprised mostly non- delinquent individuals. The results revealed a significant difference in the subjective sexual arousal ratings as well as sexual reactivity between pedophiles and control participants in response to both child and adult stimulus categories. Correlation analysis revealed a significant positive relationship between subjective ratings and sexual reactivity to both child and adult stimulus categories. The results indicate that the audio recordings are a suitable tool to distinguish between pedophiles and controls. The...

Comparison of Accuracy and Precision of Sexodiagnostic Methods of Penile Plethysmography and Viewing Time
Trojan, Ondřej ; Weiss, Petr (advisor) ; Zvěřina, Jaroslav (referee) ; Pastor, Zlatko (referee)
Charles University Prague, Czech Rep. Raculty of Philosophy Department of Psychology Doctoral Theses Comparison of Accuracy and Precision of Sexodiagnostic Methods of Penile Plethysmography and Viewing Time Ondřej Trojan, 2017 Abstract The diagnosis of pedophilia denotes (according to ICL 10) the erotic preference for prepubescent or early pubescent children. Penile plethysmography (PPG) measures the reaction of these men in respon- se to either visual stimuli or to erotic narrative stories including child objects. Penile plethysmography is quite an intrusive assessment method, so viewing time (VT) might be a good alternative if it is shown to be compapratively accurate. Several studies in the past have shown inconsistent data, therefore more research is needed to confirm its validity in distinguishing responses to the preferred age category of pedophilic men. Method: Participants were 30 self-referred admitting paedophiles aged between 18 and 55 in the experimental group and 30 heterosexual gynephile men in the comparison group. A set of photographs depicting naked adults in addition to male and female children across 6 age categories ranging from young infants to adolescents was used; the same set of 38 stimuli were used to measure PPG (first) and VT(after). PPG apparatus was used to measure penile...
