    The objective of this research is to measure how long the search for semen is prolonged in cases of possible sexual crimes, 2023. The sample consists of 100 vaginal and perianal swabs from alleged victims of sexual assault in Lima. The methodology adopted was observation, and a data collection sheet or checklist was used, within the framework of a non-experimental, quantitative research study. From the findings, it is observed that the persistence time in cases of alleged sexual assault crimes in 2023 is directly related to the investigation of semen, evidenced by a Spearman correlation coefficient of 0.753, which suggests a high correlation between the variables. Given that the p-value is 0.000 (less than 0.05), it is considered significant. Therefore, the null hypothesis is rejected, accepting the alternative hypothesis, concluding that the persistence time has a significant impact on the investigation of semen in cases of alleged sexual crimes in Lima, 2023. In addition, it is observed that, as time passes from the incident to sample processing, the presence of sperm and prostate-specific antigen (PSA) decreases.
