At present, the crime against sexual freedom (rape) has been on the increase at the national level, so it is important to know and take into account that the sample or indication and/or evidence must be sent as soon as possible. The present research work entitled "Time as a determining factor to establish the presence of remains of Human Sperm in Biological samples in the Criminalistics Directorate PNP Lima 2017-2020", was carried out with the purpose of determining if time has an influence on the presence or absence of traces of human spermatozoa in the different types of absorbent support, such as preputial, vaginal and anal genital swabs, intimate garments (shorts and/or underpants) and clothing (trousers, blouse, shorts, polo shirts, bags, jackets, stockings), sheets, towels, toilet paper, rugs, bedspreads, non-absorbent supports, condoms, shoes, keys, glasses, flooring, the result of which was demonstrated with the certainty test (microscopic observation), applying the protocols of the Biology Laboratory Forensic – DIVLACRI – DIRCRI PNP. As a result of the analysis, it was obtained that time is not a determining factor in the presence of human sperm remains, however, it is important to mention that the type of support (absorbent) is the one that best preserves the presence of human sperm remains. Spermatozoa, as well as the adequate conservation and adequate sending of the sample to be analyzed.
