Résumé
This review aims to evaluate whether severe endometriosis has an impact on the outcome of in vitro fertilisation (IVF), whether IVF is associated with specific complications in this context, whether a specific ovarian stimulation protocol is most appropriate, whether the endometrial condition progresses following ovarian stimulation, and whether endometrial cysts pose a specific problem for IVF. In patients with severe endometriosis, IVF represents an effective treatment option for infertility, as a complement to surgery. The prognostic parameters of IVF are identical to those of other patients. However, the risks related to the severity of endometriosis, particularly the risk of ovarian deficiency, need to be considered. Because of this issue, to which endometriosis-related pain often adds, IVF treatment should be initiated as early as possible, using appropriate protocols and after having fully informed the patient about the specific oocytes retrieval-related risks.
