Fertility is rapidly restored once hormone-releasing IUDs like Kyleena are removed1

In a study of 1452 parous and nulliparous women aged 18-35 years:

  • About 71% of 163 women wishing to become pregnant conceived within 12 months after removal of Kyleena

  • If Kyleena is removed and the patient does not want to become pregnant, she should use another method of birth control

  • Patients who do not want to become pregnant should be provided a new Kyleena or another type of contraception

  • If a patient with regular cycles wants to start a different birth control method, remove Kyleena during the first 7 days of the menstrual cycle and start the new method immediately thereafter or start the new method at least 7 days prior to removing Kyleena if removal is to occur at other times during the cycle
