**1. Introduction**

Female sexual offenders [FSO] are among the most radically unrepresented sexual offenders in the criminal justice system. Some studies suggest that anywhere from 15 to 20% of sexual offenses are committed by females [1, 2]. Among the studies of female sexual offenders, one accepted explanation was that female sexual offenders might have more significant personal abuse histories than their male counterparts [3]. The CDC's Adverse Childhood Experiences (ACEs) study revealed that nearly 25% of females and 16% of males who reported being abused as a child advised that at least one of their sexual offenders was female [4]. FSOs tend to offend across genders and with a wide range of ages [5]. Also, female sexual offenders tend to have young victims, compared to male offenders, which causes a very particular set of problems for these victims, including neurological, behavioral, and other significant outcomes [5, 6]. The impact of female-specific sexual offending is a phenomenon related to, but different from, that generated by male child sexual offenders—the purpose of this chapter to explore to understand female sexual offenders' characteristics in the literature.
