Examining the genital microbiome of male partners of women with recurrent bacterial vaginosis

Official title: The Penile Microbiome in Partners of Women With Recurrent BV and Its Response to Decolonization Protocol

Run by Hadassah Medical Organization · NCT05963711 · Data updated 2026-11-12

This study is testing if the bacteria in the genital area of men can affect how often their female partners get bacterial vaginosis and whether cleaning with a certain solution can help reduce this risk.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include male partners of women participating in the vaginal microbiome transplantation study who are willing to comply with the study protocols.

Probably not a fit

Patients who have skin diseases affecting the penile area or known sensitivities to chlorhexidine gluconate may not benefit from this study.

What this trial studies

This study investigates the role of the male partner's genital microbiome in the recurrence of bacterial vaginosis (BV) in women undergoing vaginal microbiome transplantation. It aims to determine if the penile microbiome contributes to BV recurrence and whether disinfection using chlorhexidine gluconate can eliminate BV-associated bacteria. The study involves male partners of women who are participating in a related vaginal microbiome transplantation study and requires adherence to a condom use protocol. The findings could provide insights into the sexual transmission dynamics of BV.

Why it matters

Potential benefit: If successful, this study could lead to improved strategies for preventing recurrent bacterial vaginosis in women by addressing the role of male partners.

How similar studies have gone: While previous studies have not shown benefit from treating male partners for BV, this approach of examining the male microbiome in conjunction with vaginal microbiome transplantation is novel.
