At present, there is no lifelong birth control ring in the clinic, and most of them need to be removed. Because different birth control rings have different durations of use, the time of removal is also different. In most cases, birth control rings are left in the uterine cavity for a maximum of 5-10 years, after which they need to be removed. If it is not removed on time, the contraceptive effect of the IUD will decrease. Moreover, if it has been placed for too long, during the process of removing the IUD, there is a possibility that the IUD may break or the IUD itself may become embedded, which will not be easy to remove, and it will be necessary to remove the IUD by using a hysteroscope or even by cutting open the uterus. In addition, if the patient does not remove the IUD before menopause, the patient’s uterus gradually shrinks after menopause, and the IUD will irritate the patient, resulting in abnormalities such as increased leukorrhea, infection, or abdominal pain, and removal of the IUD is also very difficult.
