Abstract | OBJECTIVES: METHODS: RESULTS: The total expected number of pregnancy was 171.9 for 2,387 subjects enrolled in the study. The number of observed pregnancies related to method failure was 32 cases. The contraceptive effectiveness rates for the above 4 groups were 80.9%, 85.3%, 90.6% and 67.3%, respectively. For the group received 10 mg mifepristone plus 5 mg anordrin, pregnancy rate was 0.7% which was significantly lower than that in 10 mg mifepristone alone group (2.2%, P < 0.05). The incidences of withdrawal bleeding were 9.2%, 4.9%, 3.4% and 6.7% for the 4 group respectively. Two groups received mifepristone in combination with anordrin showed significant lower incidence of withdrawal bleeding than those in mifepristone alone groups. CONCLUSION:
