Abstract

Background: Semen is the one of the important Forensic Sample recovered from the scene of crime however the time of recovery may differ from fresh to months.

Material and Method: Semen Samples were kept at room temperature for a period of 3–6 months at room temperature to know the amount of quantitative Deoxyribo Nucleic Acid [DNA] recovery from these samples.

Results: We were able to recover intact DNA for about first 3–6 weeks after which the DNA yield was decreased drastically and after two months hardly any intact DNA recovered from these samples.

Conclusion: There is a significant chances of intact DNA recovery in seminal samples with one day of sample analysis. The liquid semen samples recovered from scene of crime after about 1–2 months is merely considered as waste.
