Abstract

Semen is considered a diagnostic fluid in forensic science which helps in diagnosis of sexual assault. The present study was conducted to determine semen biomarkers in vaginal fluid in suspected rate victims.

The present study found 20 rape victim out of 94 women. In all, vaginal swabs were obtained. In this, Semen cytology (SC), prostate-specific antigen (PSA) and Y chromosome DNA was detected with polymerase chain reaction.

Maximum victims were seen in age group 10–20 years (32) followed by 20–30 years (29), 30–40 years (28), 40–50 years (4) and >50 years (1). It was found that 20 cases were found to be positive of rape. Sensitivity of SC was found as 70%, PAS as 80% and PCR as 100%. Specificity of SC was 88%, PSA 92% and PCR as 96%. Table III shows various primers used in the study.

Semen biomarkers such as SC, PSA and Yc-DNA are widely used and accepted methods for detection of offense. They have high specificity and sensitivity rate.
