The endometrium can be removed, often in cases of excessive menstruation or overgrowth of the endometrium, etc. The endometrium needs to be removed and will not return to menstruation afterwards. If the endometrium is partially removed, it may also be possible to have a second period. The current medical development for hyperplasia or excessive menstruation can be better treated with an intrauterine Mannorrhea ring because the damage is after all smaller and the side effects are less. The IUD is a highly effective progestin that can cause the endometrial lining to become thinner after being inserted into the uterine cavity, which will reduce the menstrual flow and will inhibit the growth of the endometrial lining, which will slow down the hyperplasia of the endometrium. It is better to use the Mannorrhea ring, but of course there is no contraindication to the use of the Mannorrhea ring for the appropriate treatment.
