The T-ring is a more commonly used birth control ring, which was used more in the past. The time limit for the use of the T-ring is 5-8 years, and after 5-8 years, you need to consider changing it. If you use it for too long, the birth control ring will shift, and after it shifts, it will lose its contraceptive effect and will lead to unwanted pregnancies, so patients who have had the T-ring put in, will need to consider changing it after about 5 years. Nowadays, there are many lifelong IUDs that do not need to be removed, so if you do not have the requirement to have children for the time being, you can also consider changing the IUDs that do not need to be removed.
