Review of consequences of pregnancy in women with endometriosis

Background: Endometriosis is a chronic debilitating disease, characterized by endometrial tissue outside the uterus. It does not absolutely prevent fertilization, any possible relationship between endometriosis and pregnancy is important. This study aimed to review the consequences of pregnancy in women with endometriosis.Methods: This review was conducted by searching the keywords such as endometriosis, pregnancy retrograde menstruation in international databases including Pubmed, Science Direct, SID and Google Scholar; 60 papers were extracted, 10 papers were removed, finally, 50 papers from 2005 to 2016 were listed and data were extracted.Result: Pregnancy and live birth are protective factors for developing endometriosis. Menstruation does not occur during pregnancy or sometimes, lactation; therefore, some women experience fewer menstrual cycles. This may reduce the probability of retrograde menstruation and may be a protective factor for endometriosis. The results of epidemiological studies show the relationship between the endometriosis and premature birth, preeclampsia and increased caesarean delivery. In women with endometriosis compared to women without endometriosis, tubal pregnancy occurs nearly three times and abortion occurs nearly two times more; moreover, the risk of placenta previa, bleeding before childbirth with no clear cause and bleeding after birth may increase.Conclusion: These findings indicate that patients may require special care during their pregnancy. Finally, further studies are needed on pregnancy in these patients, and for confirming the results of this project in other populations and ethnicities with larger samples.
