The best treatment plan for adenomyosis varies with age and severity. If the woman is young and has childbearing requirements, and the adenomyosis is mild, the best treatment option is to take ibuprofen extended-release tablets or diclofenac sodium at the onset of menstruation for symptomatic pain relief, and to prepare for pregnancy as soon as possible, since the adenomyosis may shrink completely and heal on its own after pregnancy. For younger women who do not want to have children, intrauterine insertion of the Mannorrhea ring should be considered for the treatment of adenomyosis, because it can treat adenomyosis and prevent pregnancy, and it can also reduce the menstrual flow significantly, as well as relieve pain. For older women who do not have a need to have children and whose adenomyosis symptoms are severe, the best treatment option is to consider laparoscopic or open surgery to remove the uterus, because after the removal of the uterus, adenomyosis can be completely cured. Therefore, the treatment for adenomyosis patients of different ages must be decided according to the patient’s condition.
