Vulvar lichen sclerosus is non-contagious and cannot be cross-infected, but it is hereditary and can skip generations. Additionally, it is important to maintain hygiene during sexual intercourse, preferably using condoms, as this is beneficial for the condition. Furthermore, regular physical exercise should be undertaken to enhance the body's resistance and immunity. It is important to keep the area clean and dry, avoid using soap or irritating substances for cleansing the vulva, and avoid consuming spicy or irritating foods.
