Prevalence of Amsel-Defined Bacterial Vaginosis Before and After Transvaginal Ultrasound With Lubricant Application.

Emerging evidence suggests a link between hyperosmolal vaginal lubricants and bacterial vaginosis. In 80 patients undergoing transvaginal ultrasound with a standardized lubricant, we observed a significant increase in Amsel-defined bacterial vaginosis 1 to 13 days after transvaginal ultrasound compared with baseline, likely driven by heightened amine odor (odds ratio, 5.88; 95% confidence interval, 1.22-28.23).
