Patient's question:
NoDoctor's answer:
The effective period of an intrauterine device (IUD) is generally as follows: metal rings can be stored for 20 years, V-shaped silicone rubber rings for 7-10 years, and T-shaped copper-coated rings for 10-15 years. If necessary, a new ring can be inserted at the same time as removal. The ideal time for removal is 3-7 days after the menstrual period has ended.
