Manyuele Ring, also known as Manyuele IUD, has a small high-tech sustained-release layout of 1 piece of progesterone, which can ensure that a small amount of progesterone is released into the ovary every day after being placed in the ovarian cavity for five or six years, making the cervical environment, intrauterine environment and ovarian endometrium unsuitable for pregnancy, thus obtaining a very reliable contraceptive effect. At the same time, because the ovarian endometrium is dormant, it also plays a role in reducing menstrual flow and shortening menstrual bleeding time.
