Here is the English translation of the provided text: "11 years with T-rings, no discomfort, should I replace them?"

Patient's question:

No

Doctor's answer:

Alright, the IUD has reached its expiration period and should be removed from the uterus in a hospital in time to prevent it from deforming or becoming ineffective inside the uterus. Generally, metal IUDs can be stored for 20 years, silicone rubber V-shaped IUDs can be stored for 7-10 years, and copper-coated T-shaped IUDs can be stored for 10-15 years. A new IUD can also be inserted at the same time as the removal.
