Introduction: Although bacterial vaginosis prevalence varies across countries and populations, recent systematic reviews and meta-analyses indicate that 23–29% of women of reproductive age are infected. Each year, 21.2 million (22.9%) women between the ages of 14 and 49 in the United States develop bacterial vaginosis. Microenvironments are interconnected with the endocrine, immune, and other organ systems and dependent upon external and internal environmental influences. In women between the ages of 15 and 44, bacterial vaginosis is the most common vaginal disorder, according to the Centers for Disease Control and Prevention.
In our nation, 93.4% of women who are of reproductive age have vaginalis; the percentage of cases with Gardnerella vaginalis alone is 22.6%, and 53.1% have it in combination with other anaerobic bacteria, which is a significant percentage. Our research is based on the lack of information about the vaginal environment of Mongolian women and factors influencing changes in the microenvironment. Our research is based on the lack of information about the vaginal environment of Mongolian women and factors influencing changes in the microenvironment. Goal: The objective is to study how age relates to the development of bacterial and fungal vaginitis through the analysis of vaginal swabs. Materials and Methods: For our study, we selected 100 women aged 20-59 through targeted sampling from clients who underwent vaginal smear tests at “Yu Bi Lab” laboratory and “Tsetsuu” diagnostic center in Ulaanbaatar in 2023. Vaginal smear analysis was conducted using Nugent’s criteria and Gram staining. Statistical analysis was performed by comparing pathogens among the participants based on age using Pearson’s correlation method. We obtained permission to conduct research.
Through the Etugen University Biomedical Ethics Comittee convention held on march 11,2024 Results: The study divided 100 women into four age groups to examine the vaginal environment with their age and the factors influencing it. The research aimed to understand how bacterial vaginitis and fungal vaginitis evolve during reproductive age and menopause. Among the age groups, women aged 20-29 had an average of 5.59±3.35 epithelial cells (n=32), those aged 30-39 had 6.10±3.29 (n=37), women aged 40-49 had 6.70±3.90 (n=17), and women aged 50-59 had the highest number of epithelial cells at 9.42±8.19 (n=14), representing 34% of the group. Conclusion
1. Women of reproductive and menopausal age experience changes in the vaginal environment due to various factors. This includes a decrease in the ratio of normal microorganisms and lactobacilli, an increase in the number of conditional pathogens, and the development of an alkaline environment in the vagina.
2. Bacterial vaginitis predominantly affects younger women, with symptoms often being subtle. In contrast, fungal vaginitis is more common among menopausal women. Lower estrogen levels in women in this age group cause lactobacilli to break down glycogen less efficiently into lactic acid, even though the number of lactobacilli is still normal. This research implies that suppositories and estrogen pills may help treat these problems for women between the ages of 40 and 59.

As a result of research exploration patronage appointments to the experts from the International Court institutes Mongolian investigators and the court, responsible for the prosecution of all subjects are interrelated trial research organizations on what industry experts dispute appointment, without question important to them in the case, We are hoping that we will improve awareness of the trial research group. This case will be much easier to defend the interests of participants in the dispute as a possible peace party funds to resolve the case easy to save money and time. Administrative regulations of the Criminal Procedure Code, Civil Procedure Code, Trial expert law has no regulation of expert safety circumstance, but regulated the case participants, and the integrity of the trial exploration object and rights. Moreover, it regulates about that expert must explore inton of criminal case. And there is problem that anyone can threat the experts because of lack of regulation about it. Therefore, Trial experts must provide bythe legal framework ensure in order to protect them from any pressure and subjectively impact.
