By examining the rates of genital injury, sperm detection, significant acid phosphatase (ACP) and prostate specific acid phosphatase (PAP) activity of 633 women reported that they were raped, we analyzed the significance of these factors as proof of rape. METHODS: We retrospectively reviewed the medical records of genital injury, sperm detection, ACP and PAP activity of 633 women who had visited National Police Hospital to report forced sexual intercourse from September 1st, 2005 to March 31st, 2007. RESULTS: The rate of having genital injuries was 16.27% and the rate of detecting sperm in vagina was 36.6% in 633 female victims. The total detection rate of ACP (>300 U/L) was 30.4% and the detection rate of ACP (>300 U/L) was lower than 50% if the time interval was over 24 hrs after being raped even though sperm was detected in vaginal smear. The ACP activity and PAP activity showed almost same results. CONCLUSION: The rates of genital injury, sperm detection, significant ACP activity (>300 U/L) were lower than we expected. Therefore even though these factors are important evidences proving that the victims were raped, it is not easy to conclude that the victims were not raped just because these factors does not fully supporting the case.
Key Words: Rape, Sperm, Genital injury, Acid phosphatase (ACP) activity
