Introduction

Structural magnetic resonance imaging (MRI) of the brain is increasingly being used to investigate possible neuroanatomic correlates of the various erotic age-preferences. Five such preferences are commonly distinguished in adult subjects, according to the category of persons who are most attractive sexually to the subject: pedophilia (prepubertal children in Tanner Stage 1, generally age 10 or younger), hebephilia (early pubertal children in Tanner Stages 2 and 3, generally ages 11 through 14), ephebophilia (late pubertal adolescents in Tanner Stage 4, generally ages 15 and 16), teleiophilia (adults in Tanner Stage 5, between the ages of physical maturity and physical decline), and gerontophilia (the elderly).

Three MRI-based studies of pedophilic patient samples have been published to date. Schiffer et al. (2007) analyzed 18 patients and 24 healthy, non-offender controls, hypothesizing differences in frontal and OCD-related brain structures. They applied small volume...
