Feasibility of an Oral Intervention for Sexual Health in Transgender Men

Completed · Not applicable · Has a placebo group

Conditions studied: Vaginal Dysbiosis, Vaginal Disease, Molecular-bacterial Vaginosis

In brief

Transgender men (TGM) have a high incidence of sexually transmitted infected (STIs), including HIV, HPV and bacterial N. gonorrhea and C. trachomatis. In addition, TGM who start testosterone therapy (TT) experience significant vaginal morbidity that causes vaginal dryness and pain, due to the estrogen-inhibiting effects of TT on vaginal epithelium. Vaginal dysbiosis is a known contributor of increased STI risk and vaginal symptoms. In a future study, the investigators are planning a randomized trial of a 6-month oral Lactobacillus probiotics intervention in TGM on TT at the Callen-Lorde Community Health Center (CLCHC), New York City to determine whether this intervention can improve vaginal health in TGM on TT. In this study, the investigators will conduct a pilot and feasibility study to precede the main trial. The investigators will randomize 30 TGM on TT to receive either the intervention (consisting of Lactobacillus acidophilus GLA-14 and Lactobacillus rhamnosus HN001) or placebo (maltodextrin) for 4 weeks, evaluating the intervention's impact on vaginal microbiota and clinical outcomes, as well as its feasibility, acceptability, and adherence. This study will take place at the CLCHC Brooklyn site, aiming to gain pilot data, address feasibility and acceptability, and plan for the main trial accordingly.
