Flourish Vaginal Care System to Establish Neovaginal Microbiome

Not Applicable

Completed

• Conditions: Neovaginal Microbiome

• Registration Number: NCT05372770
• Lead Sponsor: Vaginal Biome Science

Brief Summary

This study examines whether use of a commercially-available vaginal wellness system is able to establish a microbiome in transgender women.

Detailed Description

Very little is known about the neovaginal microbiome, but it has been described as being a polymicrobial state similar to bacterial vaginosis (BV) in cis women. The Flourish Vaginal Care System is a commercially-available over-the-counter vaginal wellness kit that helps relieve symptoms of BV. This study is intended to determine whether that kit could also help transgender women who have recently undergone gender-confirming surgery to establish a neovaginal microbiome that is dominated by lactobacilli, as observed in healthy cis women. This could increase health and subjective satisfaction of the neovagina. This study examines the (neo)vaginal microbiome in transgender women with and without using Flourish, as well as a group of healthy cisgender women.

Primary Outcome Measures

Name	Time	Method
Vaginal microbiome	Collections at time 0, 6 weeks, and 6 months	Observation of changes in the composition of the vaginal fluid microbiome over six months using commercially available next-generation sequencing kit (16s rRNA). Biomes will be categorized to "community state type" (Ravel 2011), and genus- or species-level relative abundance will be compared.
Vaginal pH	Collections at time 0, 6 weeks, and 6 months	Observation of changes in vaginal pH over six months by pH strip

Secondary Outcome Measures

Name	Time	Method
VSQ	Collections at time 0, 6 weeks, and 6 months	Responses to the Vulvovaginal Symptoms Questionnaire
