Women with severe lichen sclerosus may not be able to have sexual intercourse because of either the pain or the scarring that narrows the entrance to the vagina. However, proper treatment for lichen sclerosus with a highly potent topical corticosteroid can help restore normal sexual functioning, unless severe scarring has already narrowed the vaginal opening. In this case, surgery may be needed to correct the problem, but only after the disease has been controlled.
