## Most Common Site of Injury in Sexual Assault **Key Point:** The genital tract — particularly the vulva, vagina, and perineum — is the most frequently injured site in cases of sexual assault, occurring in 40–60% of rape cases. ### Anatomical Vulnerability The genital region bears the direct force of penetrative assault and is highly vascularized with thin, delicate mucosa prone to: - Lacerations and abrasions - Bruising and ecchymosis - Bleeding and blood staining - Hymenal tears (in adolescents and young women) ### Frequency of Injuries by Site | Site | Frequency | Type of Injury | |------|-----------|----------------| | Genital tract (vulva, vagina, perineum) | 40–60% | Lacerations, bruising, abrasions | | Anal region | 15–25% | Fissures, lacerations, bleeding | | Oral cavity/pharynx | 5–15% | Bruising, lacerations, petechiae | | Breasts/chest | 10–20% | Bruising, bite marks | | Extragenital sites (arms, legs, neck) | 30–40% | Defence injuries, restraint marks | **High-Yield:** Absence of genital injury does NOT exclude sexual assault — consensual intercourse and some forced intercourse may leave no visible injury, particularly in post-menopausal women or those with elastic tissues. ### Clinical Pearl Defence injuries (scratches, bruises on forearms, hands, neck) are often more common than genital injuries because the victim attempts to resist or protect herself. However, the **genital tract remains the single most common site of direct assault injury**. ### Forensic Documentation All injuries must be: 1. Photographed with scale and consent 2. Described in detail (size, shape, color, location) 3. Documented on a body map 4. Correlated with the victim's account **Warning:** The absence of injury does NOT negate the allegation of rape — many assaults involve psychological coercion without physical trauma.
