Clinically speaking, the translucent ring examination is to find out whether the position of the ring is normal or not through X-ray. Once the position of the IUD is abnormal, it will not work as a contraceptive in the clinic, so it is very important for women who have the IUD to have an annual fluoroscopy. After the implantation of the IUD, it will play a good role in contraception for the majority of women, but some women may still get pregnant despite the implantation of the IUD. Therefore, it is recommended to go to the hospital for examination as soon as possible to rule out the possibility of pregnancy once menopause occurs in the clinic. In addition, women who have an IUD must know how long the IUD is valid for, after the expiration date, the IUD will not work as a contraceptive and should be replaced with a new one in a timely manner.
