Probiotics help to provde optimum balance in the intestines probiotics species competitive blocks toxics substances and growth of unwanted species in their struggle for space and food. Lactogyn is the first oral probiotics wich protects vaginal flora. The most researced probiotic is the Lactobacillus rhamnosssus. The goal of this study is to exam influence of probiotics to cytological smear test including: reliability for easier detection of atypical cells; false positive and false negative test; faster cytodiagnostic; incidence of invasive diagnostic procedures and incidence of intraepithelial and invasive changes of the lower genital tract. This study involved two groups of patient: the first one included 50 patients who has been taken specific probiotic therapy after taking cytological cervical smear test. The second one included 50 patients who has taken specific probiotic therapy before taking cytological cervical smear test. In the second group we discovered: statistically lover number od invasive diagnostic and therapeutic methods and statistically higher number of patients without invasive methods. It was statistical higher incidence of cytological smears with inflammations and ASCUS (atypical squamous cells undetermined significance) in the second group of patients. Lactogyn treatment with other medicament therapy provides: faster and better cytological diagnostic, decreases the number of cytological tests and invasive diagnostics methods per women, decreases the number of false positive and false negative tests and the percent of unsatisfactory tests and borderline satisfactory tests
