Abstract: This study addresses the delicate issue of sexualized relationships in the family, with particular reference to the phenomenologies of sexual abuse and incest, as well as to the role and stages of scientific investigation of forensic medicine in their detection. If, from a legal point of view, incest refers to situations in which family morality is violated (which is the object protected by Article 564 of the Italian Criminal Code) through the performance of sexual acts that cause public scandal, in social perception the notion of incest is referred to all those cases in which sexual violence is performed between subjects belonging to the same family.
