What causes vulva itch?

Itching in the vulvar region can result from irritation, allergy, inflammation, infection or cancer. Many of the infections that can cause vulva itch are contagious. Other conditions that cause vulva itch are not contagious.

Infectious causes of vulva itch

Vulva itch may be caused by infections including:

  • Bacterial vaginosis (imbalance of bacteria in the vagina leading to overgrowth of certain types of infections)
  • Genital herpes (sexually transmitted disease caused by the herpes simplex virus type 1 or 2)
  • Pubic lice (also called “crabs”; parasitic insects that live in the pubic hair)
  • Scabies (contagious skin disease caused by small mites)
  • Tinea cruris (“jock itch” or “ringworm of the groin”; fungal skin infection)
  • Trichomoniasis (sexually transmitted disease caused by the protozoan parasite Trichomonas vaginalis)
  • Yeast infection

Other causes of vulva itch

Vulva itch can also be caused by other diseases, disorders or conditions including:

  • Allergic reactions
  • Atopic dermatitis or eczema
  • Atrophic vaginitis (thinning and inflammation of vaginal tissues related to a drop in estrogen levels)
  • Chemical irritants, such as soaps, feminine hygiene products, perfumes, lubricants, douches, or creams
  • Lichen simplex chronicus (chronic skin condition associated with itching and scratching and thickening of the skin)
  • Precancerous changes of the vulva
  • Psoriasis (itchy skin condition associated with skin irritation and redness, often with areas of thickened, red skin with white flaky patches)
  • Vulvar cancer

  • Is there anything that seems to make it better or worse?
  • Do you have any other symptoms?
  • Have you been intimate with anyone who has similar symptoms?
  • Are other areas of your body affected?
  • What medications are you taking?

What are the potential complications of vulva itch?

Irritation and allergy can occur as a result of exposure to soaps, feminine hygiene products, perfumes, lubricants, douches, creams, or latex.
