The IUD needs to be replaced after 3-5 years, because the ring needs to have a certain lifetime limit. If the life expectancy exceeds a certain limit, first of all, the contraceptive effect will not be effective or will decrease, and it can cause an increase in the chance of infection in the uterine cavity and upstream infection, as well as the chance of ring dislocation and even ring displacement. Therefore, when the ring is more than 5 years old, it is better to actively replace the ring as much as possible to avoid some women staying until menopause when the ring can be planted at the base due to uterine atrophy. It is necessary to be hospitalized for a combined hysteroscopic surgery to help remove the ring and to avoid the ring from migrating into the pelvic cavity and traveling to various parts of the body, which can also have certain effects on the body.
