OBJECTIVE The aim: Determination of regional blood origin in cases of sexual violence, establishing the possibility of using prostaglandin F2alpha as a marker of blood of menstrual origin. PATIENTS AND METHODS Materials and methods: The material for the study were samples of vaginal fluid, menstrual blood and capillary blood from females, the age distribution of women was carried out according to the gynecological classification according to the age periods of women's lives depending on the functional state of their reproductive system: the first group - women at the age of 18-29, the second group - women at the age of 30-45. RESULTS Results: Among objects of biological origin, fluids, especially blood, occupy an important place. The content of PGF2α has age fluctuations: its content is higher by 6-12% in women aged 30-45 than in women 18-29 years old. PGF2α levels above 13.1 ng / mg of dry tissue are a reliable sign of blood of menstrual origin, which is very important in determining the regional origin of blood in forensic examinations for sexual violence / sexual crimes. CONCLUSION Conclusions: In cases of sexual violence against women, in addition to recording external harm, attention should also be paid to the examination of objects of biological origin, identification by species, sex, regional, organ or cell.
