Spermaspuren in der gerichtlichen Medizin

Abstract

Furnishing proof of human seminal stains is part of daily forensic work in investigations of sexual crimes. In the last two centuries different methods have been described for confirming putative sperm traces. These methods ranged from identification of the smell and appearance of the stain, to simple chemical reactions such as precipitation of crystals and enzymatic proof of acid phosphatase, which are now enhanced by analytic methods of modern molecular biology. This discourse gives a review of the development of different forensic methods for detection of sperm traces, illustrated with historical case studies.

Diagnostic Value of PSA and AP Tests for the Detection of Spermatozoa in Postmortem Swabs from the Genital and Anal Region in Males

“…We believe that one of the strengths of our study is the usage of methods that are everyday forensic practice, including microscopic evaluation of the presence of spermatozoa which is still considered the gold standard . Lunetta et al.…”

“…PSA was discovered and further analyzed in the 1960s and 1970s, while the application and evaluation of PSA testing for forensic purposes started in the 1980s and 1990s . AP was first described in the forensic literature in the 1940s .…”

AP was first described in the forensic literature in the 1940s . The application of PSA and AP for the evaluation of sexual activity prior to death in postmortem cases has been studied on vaginal swabs, and one study found good agreement between the results for PSA testing and microscopic detection of spermatozoa in 85% of investigated cases .…”
