The Adult Male Rape Victim: Forensic Description of a Series of 57 Cases.

A retrospective analysis on 57 adult male victims of sexual violence has been performed. Age, nationality and anamnesis of the victims, location of the assault, type of violence, number and identity of the assailants, presence of physical injuries, lapse of time between the assault and the request of medical assistance, and toxicological and semen detection tests were analyzed. Victims were mostly in the 31- to 40-year age group. Ten victims referred themselves as either active homosexuals or bisexuals. Forced oral and/or anal penetration was registered in 86.8% of cases, mostly performed by a single assailant. Anogenital injuries were recorded in 61.4% of cases, whereas extragenital injuries in 35.1%: abrasions and perianal reddening were the most frequent acute anogenital marks, whereas the head and lower limbs were the body parts most commonly affected by blunt trauma. No clinically severe injuries were found. Anal and perianal swabs for semen detection tested positive in less than 20% cases, whereas oral swabs always tested negative. When performed, nearly 50% of cases tested positive in drug tests, above all for psychoactive substances. No definite forensic diagnosis in terms of confirmation of rape was possible on the basis of type and topography of injuries.
