The control group did not receive any treatment. Vaginal mucosa was collected after 3 and 12\u2009months of treatment. The former was used for 16S rRNA sequencing, and the latter was used for pathological evaluation. Vaginal health and voiding function were assessed using the vaginal health index (VHI) scale and the UDI\u20106 scale at 3 and 12\u2009months after treatment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The results showed that both treatments reduced alpha diversity in the vaginal flora. Additionally, the abundance of 65 genera differed significantly between the treatment and control groups, with an increase in potentially beneficial bacteria such as <jats:italic>Lactobacillu<\/jats:italic>s, <jats:italic>IheB3_7<\/jats:italic>, <jats:italic>Mycoplasma urealyticum<\/jats:italic>, and <jats:italic>Streptococcu<\/jats:italic>s. In addition, the VHI and UDI\u20106 scores improved in both treatment groups compared to the control group after 3\u2009months. Whereas VHI and UDI\u20106 scores were close to baseline in the estrogen group, and remained significantly improved in the CO<jats:sub>2<\/jats:sub> laser group after 12\u2009months. Pathological results showed that both methods improved the vaginal health status of patients with GSM after 12\u2009months of treatment. However, the CO<jats:sub>2<\/jats:sub> group exhibited a more significant increase in type III collagen.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Both CO<jats:sub>2<\/jats:sub> laser and estrogen therapies can regulate the vaginal flora imbalance of GSM and improve the corresponding symptoms.
