ADENOMYOSIS
This study has some limitations. First, this trial was conducted only in China. Second, endometrial biopsy was not performed, owing to ethical principles, and no obvious anomalies in the endometrial thickness of patients were detected by ultrasonography. Third, this trial was limited to 12 weeks of treatment, and future research to assess the long-term effects of mifepristone therapy for adenomyosis is still needed.
