title: [The forensic value of morphologic-morphometric sperm differentiation in trace studies. I: Methods].
abstract: Proceeded from examination of sperm samples of 200 men, controls of sperm samples from 81 men during a determined period (5 sperm samples from each man within a period up to 70 days) and in view of trace-conditioned influences, the feasibility of a morphologic-morphometric differentiation of spermatozoa is demonstrated with sperm traces and comparative material. The following items are shown: necessary marginal conditions such as quantity and quality of spermatozoa available, application of the elaborated 37-item spermiocytogram in connection with the introduced indices of identification as well as the observance of a maximum period of 30 days between the formation of a criminologically relevant sperm trace and the separation of comparative samples. The method is used in group identification in terms of criminological identification theory.
