Objective To investigate the effect of uterine artery embolization on ovarian function of patients with scar pregnancy. Methods From January 2012 to December 2016，patients with uterine scar pregnancy aged less than 40 years in Handan central hospital were randomized into the uterine artery embolization group （study Group）and other methods treatment group（control group），92 cases in each group. The patients were followed up for 3 years. The menstrual cycle length，follicle stimulating hormone（FSH），estradiol（E2）and the number of ovarian antral follicles of the two groups were regularly monitored and analyzed. Result In UAE group， the number of menstrual cycle，FSH，E2 and ovarian antral follicles were（30.12 ± 3.05）days，（5.10 ± 1.08）IU/L， （55.00 ± 11.07）pg/mL and（5.89 ± 1.47）in the 6th month，（29.97 ± 1.98）days，（5.24 ± 1.14）IU/L，（58.35 ± 12.23）pg/mL and（5.65 ± 1.67）in the 12th month，（30.17 ± 1.73）days，（5.43 ± 1.25）IU/L，（57.67 ± 10.87）pg/mL and（5.51 ± 1.67） in the 24th month，and（29.78 ± 2.1）days，（5.42 ± 1.29）IU/L，（59.00 ± 12.07）pg/mL， and（5.61 ± 1.65）in the 36th month after treatment，respectively. There was no significant difference in each period （all P > 0.05）. Conclusion Uterine artery embolization in the treatment of scar pregnancy and other treatment methods will not cause ovarian function and menstrual cycle changes in 3 years.
