An inflammatory skin condition that produces itching, white thickened patches, splitting, and over time the fusion or loss of vulval structures. Sex becomes painful because the skin tears and because the entrance narrows. It is very often mistaken for thrush or for menopausal dryness for years, and the delay matters because untreated it causes permanent scarring and carries a small increased cancer risk.

A new lump, ulcer, or non-healing sore on the vulva needs urgent assessment — this condition carries a small increased cancer risk.
Persistent itching that has been treated as thrush repeatedly without resolving needs a proper examination.
What the condition itself tends to do
Editorial categories, not percentages, and never a prediction about you. Each links to the fuller picture of that change.
Burning, tearing, or aching pain with penetration. Pain is never a symptom to work around with a product — it is the one entry on this list that always deserves assessment.
Less natural lubrication, a tight or raw feeling, or discomfort that arrives during rather than before sex. Medicines cause this either by drying mucous membranes generally or by lowering oestrogen.
Wanting sex less often, or losing the spontaneous interest that used to arrive on its own. This is the effect people most often assume is psychological and most often is not only psychological.
The body responds less, or much more slowly, even when the interest is there. Blood flow, nerve signalling, and hormone levels all feed this, and medicines can act on any of the three.
Condition or treatment?
The treatment is a prescribed topical steroid used long term, which is not something this site can advise on beyond saying that it is the standard of care and that under-using it is the common failure. Moisturisers and lubricants make it more comfortable; they do not treat it.
For almost every condition on this site, the condition and the medicines that treat it both affect sex — by different mechanisms, on different timescales, and with different answers. Being able to say which half you are asking about is the single most useful thing you can bring to an appointment, and it is the thing patients are least often given.
No medicine class on this site is a standard treatment for this, which is itself useful to know — if a treatment is being suggested, it is worth asking what it is expected to do.
What helps
A bland emollient and a glycerin-free lubricant reduce friction and splitting alongside prescribed treatment.
Stop all soaps, washes, and fragranced products on the area entirely.
Regular review matters here more than for most skin conditions, because of the small cancer risk.

Common questions
How does lichen sclerosus affect sex?
An inflammatory skin condition that produces itching, white thickened patches, splitting, and over time the fusion or loss of vulval structures. Sex becomes painful because the skin tears and because the entrance narrows. It is very often mistaken for thrush or for menopausal dryness for years, and the delay matters because untreated it causes permanent scarring and carries a small increased cancer risk.
What are the most common sexual effects of lichen sclerosus?
The effects reported most often are pain during penetration and vaginal dryness or less natural lubrication. Reported does not mean inevitable — the picture varies a great deal between people, and most people have more than one thing contributing at once.
Is it lichen sclerosus or the treatment for it?
The treatment is a prescribed topical steroid used long term, which is not something this site can advise on beyond saying that it is the standard of care and that under-using it is the common failure. Moisturisers and lubricants make it more comfortable; they do not treat it. Timing is the most useful clue you have: an effect that appeared within weeks of starting or changing a treatment points at the treatment, while one that predates it points at the condition. Never stop, pause, or change a prescribed treatment to find out — take the timeline to the person who prescribed it.

When should I raise this with a clinician about lichen sclerosus?
Sooner than most people do, and specifically without waiting: A new lump, ulcer, or non-healing sore on the vulva needs urgent assessment — this condition carries a small increased cancer risk.
Educational information about what a diagnosed condition tends to do — not a diagnosis, not a way to work out whether you have something, and not advice about your treatment. Conditions on this page overlap, and most people with a long-term condition have more than one thing affecting them at once. Nothing here can examine you or run a test. Pain, bleeding, or a new and unexplained symptom always deserves assessment.
