Endometrial hyperplasia can be treated by wearing the Manned Ring, which is a highly effective progestin slow-release system that can release the highly effective progestin levonorgestrel in a quantitative amount every day, which can treat endometrial hyperplasia and can play a role in contraception. It can also treat gynecological diseases such as adenomyosis and excessive menstruation. Endometrial hyperplasia is divided into atypical endometrial hyperplasia and endometrial hyperplasia without atypia. For younger women, if they have abnormal uterine bleeding and pathological examination shows endometrial hyperplasia, they can have intrauterine placement of the IUD, which can play a role in contraception and can also effectively treat endometrial hyperplasia. However, 3 months after IUI, it is recommended to perform hysteroscopic endometrial scraping again to understand the status of the endometrium after IUI and whether it is in a reversed state or not, if the endometrium is normal, it can be observed again.
