Does the IUD cause vaginal dryness as side effect?
Hormonal IUDs (such as the Mirena® or Kyleena®) may cause vaginal dryness in a small percentage of users, mainly due to local progestin effects. Copper IUDs do not typically affect vaginal lubrication.
Detailed Medical Explanation
Hormonal IUDs release progestin, which can cause local thinning and dryness of the vaginal tissues in some women, though this is less common than with birth control pills. The copper IUD is hormone-free and does not affect oestrogen levels, so dryness is not expected. Any new vaginal symptoms after IUD insertion should be discussed with your doctor to rule out infection or other causes. NHS: IUD Side Effects.
Clinical Context
If you notice vaginal dryness after starting a hormonal IUD, discuss it with your clinician. Simple remedies or alternative contraception may be advised if symptoms persist.
Evidence-Based Approaches
Guidelines support reviewing hormone-related side effects and personalising contraception choices. Most women tolerate IUDs well, but alternatives are available if symptoms are bothersome. RCOG: IUD & Vaginal Symptoms.
