Feasibility of an Oral Intervention for Sexual Health in Transgender Men

The intervention is a mixture of two probiotics: 1) Lactobacillus acidophilus GLA-14 and 2) Lactobacillus rhamnosus HN001. These products will be combined into a single capsule/sachet with a dose of approximately 10\^10 colony forming units (CFUs) of GLA-14 (ATCC SD5212) and HN001 (ATCC SD5675) in a 4:1 ratio, using similar doses as recent studies using this product.

The placebo will of be Maltodextrin, a carbohydrate, packaged similarly to the intervention and having the same weight.
