Abstract: Testicular displacement is a rare clinical presentation of blunt scrotal injury that may take place in road traffic accidents involving motorcycle occupants. We are presenting two cases of motorcycle occupant fatalities, 21 and 24 years of age, where testicular displacement and other signs of groin trauma have been determined. In both cases, discrete external signs of scrotal trauma were noted on examination, while unilateral and bilateral traumatic testicular displacement, respectively, have been documented at autopsy. For motorcycle occupants involved in collision, it is necessary to perform a thorough analysis of injuries, in particular to look for specific trauma arising from fuel-tank impact to genitalia and/or groin. These injuries are of great medico-legal importance both at postmortem and in clinical cases involving motorcycle occupants involved in collision.
