Abstract：Objective To investigate the natural pregnancy and its influencing factors in patients with ovarian endometriosis（EMT）. Methods 68 cases of ovarian EMT patients were selected as the research objects.All patients were treated with surgery.The patients with natural pregnancy were included in the pregnancy group,and the non pregnant patients were included in the non pregnancy group.The age,body mass index（BMI）,lesion location,cyst diameter and whether to accept gonadotropin stimulation were compared between the two groups GnRH-a treatment,American Society of reproductive medicine EMT（R-AFS）stage,EMT fertility（EFI）score. Results Among the 68 patients,50 cases were naturally pregnant and 18 cases were not pregnant.Univariate analysis showed that the natural pregnancy of patients with ovarian EMT was not related to BMI and lesion location（P>0.05）,but might be related to age,cyst diameter,R-AFS stage and EFI score（P<0.05）.Logistic regression analysis showed that older age,cyst diameter≥3cm,R-AFS stage ≥ stage III,EFI score<7 were risk factors for non pregnancy in patients with ovarian EMT（or>1,P<0.05）.GnRH-a treatment was a protective factor for spontaneous pregnancy in patients with ovarian EMT（or>1,P<0.05）. Conclusion The natural pregnancy rate of patients with ovarian EMT is affected by many factors.The risk factors of non pregnancy are old age,cyst diameter ≥ 3cm,R-AFS stage≥stage III,EFI score<7.GnRH-a treatment is the protective factor of spontaneous pregnancy.
