The IUD is easy to remove because it is a contraceptive device with a tail wire. Also known as the levonorgestrel intrauterine device (IUD), the IUD is a safe and effective form of contraception. It also works by releasing 25ug of levonorgestrel per day and is therefore very effective in treating abnormal uterine bleeding such as adenomyosis, endometriosis, endometrial polyps and excessive menstrual flow. The validity period of the Manned Ring is 5 years, but for adenomyosis it is only valid for 3 years. Generally, you can wear the IUD after your menstruation. As long as the IUD is in the uterine cavity, it can play a role in contraception and treatment of abnormal uterine bleeding, and the IUD can be removed after your menstruation.
