The anterior position of the uterus does not increase the chances of success of medication abortion, on the contrary, it is likely to affect the chances of success of medication abortion in individual cases. The female uterus anterior position is mainly divided into three cases: first, the uterus mobility is very good, is due to the female body position change into anterior position, the female body position change may become horizontal position or posterior position. The success rate of drug abortion in this case is not subject to any, as long as more activities can increase the chances of success. Second, the uterus has inflammation or other reasons leading to adhesions, and the uterus is in anterior position, but there is no flexion. This situation will not affect the success rate of medication abortion, the patient medication abortion only need more activities, with blood circulation, promote uterine contraction of drugs, the success rate is still relatively high. Third, the uterus is excessively anterior flexion, the success rate of drug abortion is very low, because the anterior tilt of the pregnancy sac as well as the meconium will be very difficult to be discharged from the body smoothly, and gathered in the uterine fundus, so, this situation is not recommended to do drug abortion.
