Summary
There is strong observational evidence that sexual activity plays a key role in Bacterial Vaginosis (BV) acquisition and recurrence. Microbiological data support the contribution of sexual transmission to the pathogenesis of BV through the exchange of BV-associated bacteria (BVAB) between sexual partners. Although BV epidemiology strongly suggests sexual transmission, treatment of sexual partners is not recommended, based on prior treatment studies of male partners of women with recurrent BV, which showed no benefit with male treatment. Nevertheless, male condom use is highly protective against recurrent BV. This study aims to evaluate the male-partner's genital microbiome as a potential source of BV-recurrence in women undergoing vaginal microbiota transplantation (NCT04517487), and whether disinfection can eliminate BV-associated penile microbiome.

Interventions
In case BV associated bacteria will be identified (using molecular sequencing) in male samples, decolonization attempt will be conducted, using a daily wash for 5 days with chlorhexidine gluconate 4%. Following decolonization attempt, male participants will undergo re- sampling, to assess for microbiome changes. In case there is no change in microbial composition, partners will be instructed to repeat decolonization protocol, and apply a 2 cm diameter volume of 2% clindamycin cream topically to the head of the penis and upper shaft (under the foreskin if uncircumcised) twice daily for seven days following repeated decolonization. Re-sampling will follow.
