The Mannuelle Ring does not usually reverse endometrial hyperplasia, however, it does inhibit endometrial hyperplasia. In addition to contraception, the IUD can stabilize the release of the progestin levonorgestrel, which leads to the inhibition of hormone-induced endometrial hyperplasia. It can also be used to treat gynecological disorders such as excessive menstruation and adenomyosis. However, Mannitol Ring does not have a therapeutic effect on the already hyperplastic endometrium. Adverse effects of MENCIL include spotting bleeding, menorrhagia, excessive bleeding and irregular bleeding; it is contraindicated in patients with lower genital tract infections, postpartum endometritis and cervicitis. It should be noted that there are certain risks associated with the use of Mannuelle Ring, and it should be used under the guidance of a specialist to avoid adverse effects.
