The Role of Fertility Preservation in Women with Endometriosis: A Systematic Review.

OBJECTIVE: To summarize the available evidence concerning fertility preservation techniques in the context of women with endometriosis. DATA SOURCES: We searched for studies published between 1984 and 2019 on endometriosis and Assisted Reproductive Technology outcomes. We searched MEDLINE and PubMed and performed a manual search of reference lists within identified studies. METHODS OF STUDY SELECTION: A total of 426 articles were identified, and 7 studies were eligible to be included for the systematic review. We included all published studies, excluding reviews, case reports, and animal studies. TABULATION, INTEGRATION, AND RESULTS: Despite a significant increase in the number of studies addressing fertility preservation over the study period, we found a relative lack of evidence addressing the use of fertility preservation techniques in women with endometriosis. The studies identified included 2 case reports, 1 histological science study, and 4 retrospective cohort studies. CONCLUSION: Women with endometriosis may benefit from fertility preservation techniques. However, there currently is a paucity of data in this population, especially when compared with other indications for fertility preservation. Although much knowledge can be translated from the oncofertility discipline, we have identified and discussed endometriosis-related changes to ovarian reserve and oocyte health that justify further well-designed research to confirm that fertility preservation outcomes are similar for women with endometriosis.
