What this trial studies
This trial investigates the impact of the contraceptive method Phexxi on the vaginal microbiome, specifically its ability to promote lactic acid-producing lactobacilli. It employs a pre-post study design, assessing participants' vaginal microbiome before and after a four-week course of Phexxi. The primary outcomes include an increase in beneficial lactobacilli and a reduction in symptoms of vulvovaginitis. The study is conducted at Queen's Medical Center, where eligible patients will be approached by clinicians for participation.
Why it matters
Potential benefit: If successful, this study could lead to improved management of bacterial vaginosis and vulvovaginal candidiasis in women.
How similar studies have gone: While the approach of using Phexxi is novel, similar studies have shown promise in modifying the vaginal microbiome to improve health outcomes.
