Patients in control group were give Gestrinone with oral,and in observation group were give left acetylene connaught progesterone intrauterine placed treatment slow-release system. The information of pain scores,menstruation, uterine volume,endometrial thickness were recorded. Results After treatment,pain score,menstrual quantity, uterine volume and endometrial thickness in observation group were（1. 85 ± 0. 57）,（45. 37 ± 11. 94）ml, （129. 47 ± 8. 67）mm^3 ,（4. 02 ± 2. 04）mm,significantly lower than the control group（（4. 82 ± 2. 07）,（61. 47 ± 12. 07）ml,（148. 54 ± 12. 47）mm^3 ,（6. 35 ± 2. 64）mm）,and the differences between groups were statistically significant（t = 5. 397,6. 047,5. 334,4. 681 respectively;P 〈 0. 05）.
