Is lichen sclerosus contagious or sexually transmitted?
Lichen sclerosus is neither contagious nor sexually transmitted. It cannot be passed on through sexual contact, skin-to-skin touch, or sharing personal items.
Detailed Medical Explanation
Lichen sclerosus is a non-infectious, inflammatory skin disorder. It is not caused by bacteria, viruses, or fungi, and does not spread from person to person, including through sexual activity. This is important to reassure women and their partners, as there is no risk to sexual partners. You can read more at the NHS and British Association of Dermatologists.
Clinical Context
Lichen sclerosus may cause concern due to its location on genital skin, but it poses no infectious risk to others. Addressing this misconception is a key part of supportive care. Our clinic can provide further reassurance and education for affected women and their partners: Vulval Skin Conditions Clinic.
Evidence-Based Approaches
Multiple studies confirm that lichen sclerosus is an autoimmune or idiopathic condition, not an STI. National guidelines recommend education to address misconceptions. See British Association of Dermatologists.
