Materials and Methods: Retrospective review of sexual assault records at the Police General Hospital between January 1 and December 31, 2013.

Results: Six hundred thirteen females, including 358 non-consensual and 255 consensual, were included. Most of both groups were between 13 and 15-year-old, and single. In the consensual victims, 63.92% were assaulted by their lovers, while 30.73% of nonconsensual victims were assaulted by their friends. The non-consensual victims had higher rate of injury than consensual victims. The location of most injuries in both groups were hymen (30.45% vs. 10.59%, p<0.000), followed by labia minora (15.92% vs. 7.06%, p = 0.001), vagina (4.19% vs. 1.96%), external genitalia (3.07% vs. 2.75%), and labia majora (1.68% vs. 1.57%). Consensual victims did not have more injuries more than non-consensual victims (4.31% vs. 1.40%, p = 0.026). Laceration wounds were found the most (28.49% vs. 10.59%, p<0.000) in non-consensual and consensual group. In addition, abrasions (13.97% vs. 5.88%, p = 0.001), and contusion wounds were found the least (8.94% vs. 3.14%, p = 0.004).

Conclusion: Most of the victims were 13 to 15-year-old, single, and knew the assailants. In the non-consensual group, laceration, abrasion, and contusion wound were found more often, with statistical significance, at hymen and labia minora than in the consensual group. An interesting point is that similar wounds were found in sexual organs of consensual or non-consensual victims. This may help diagnose the wounds of the assaulted victims with unclear profiles.
