Identification of Semen
摘要
Semen is very important evidence in sexual assault cases. It is produced in post-pubescent males and is ejaculated in response to sexual stimulation. Clothes, beddings, and the victim’s body are common places where semen stains can be found in sexual assault cases. Its detection on evidence can help in confirming the involvement of a male perpetrator in the crime. It can also help in establishing penile penetration in sexual assault cases. Semen is a rich source of DNA as spermatozoa are the source of genetic information from one generation to another generation. Therefore, if DNA is successfully isolated, it can help in the individual identification of the perpetrator.
