RESUMO
OBJECTIVE: This study aimed to review recent data that affected the clinical management of infertility associated with endometriosis. DATA SOURCES: We completed a PubMed review of all articles that included the following keywords: endometriosis, infertility, IVF, and ART. STUDY SELECTION: A study was selected based on the pertinence of the topic addressed in relation to the study's set objectives. DATA EXTRACTION AND SYNTHESIS: All identified articles were first assessed based on a review of the abstract. Pertinent articles were reviewed in depth. CONCLUSION: Endometriosis interferes with natural conception primarily by altering the quality of gametes-oocytes and sperm-and early-stage embryos. On the contrary, recent data indicate that gametes and early-stage embryos are not altered in the case of ART. Surgery-a classical approach in yesteryears-does appear to improve ART outcomes and may affect ovarian reserve and the number of oocytes retrieved in ART. Surgery is thus more rarely opted for today and only when necessary; proceeding to fertility preservation prior to surgery is recommended. When ART is performed in women with endometriosis, it is recommended to use an antagonist or progesterone-primed ovarian stimulation approach followed by deferred embryo transfer. In this case, GnRH (gonadotropin releasing hormone) agonist is preferred for triggering ovulation, as it limits the risk of cyst formation as well as ovarian hyperstimulation syndrome. Frozen embryo transfers are best performed in E2 (estradiol) and progesterone replacement cycle.
