    Penile lichen sclerosus (PLS) is a chronic inflammatory disease affecting uncircumcised males, leading to symptoms like whitening and thickening of the foreskin.

  • 2

    Uncircumcised men have a higher prevalence of pathogenic bacteria, with significant differences in microbiota compared to circumcised individuals.

  • 3

    The study investigates the penile microbiome in males with histopathologically confirmed lichen sclerosus compared to healthy controls.

  • 4

    Potential factors contributing to lichen sclerosus include infection, chronic irritation, autoimmune reactions, and immune system dysregulation.

  • 5

    The study aims to clarify the relationship between microbiome alterations and lichen sclerosus, addressing gaps in previous research.
