O-234 Indication for fertility preservation in patients with endometriosis

Abstract

Abstract Endometriosis is a complex gynecological condition that not only causes debilitating symptoms but also significantly impacts fertility. As the disease affects approximately 10% of women of reproductive age, addressing fertility preservation strategies becomes paramount. The conventional treatments for endometriosis, such as medical therapy and surgery, often fail to fully address its adverse effects on ovarian reserve and reproductive potential. Consequently, there is a growing interest in exploring fertility preservation options, particularly oocyte cryopreservation (OOC), for endometriosis patients. Despite the prevalence and impact of endometriosis on fertility, comprehensive data and guidelines specifically tailored to fertility preservation in this population remain scarce. The available evidence suggests that endometriosis, particularly when it involves ovarian endometriomas, is associated with a significant reduction in ovarian reserve, as indicated by lower levels of anti-Müllerian hormone (AMH). Surgical interventions, often necessary for managing endometriosis-related complications, can further compromise ovarian function and diminish fertility prospects. However, recent studies have shed light on the potential benefits of OOC in preserving fertility for endometriosis patients. OOC offers a minimally invasive approach with no impact on ovarian reserve compared to other fertility preservation techniques. Despite the lack of randomized controlled trials, our retrospective data have demonstrated promising outcomes, with a notable number needed to treat (NNT) of 16 for one successful pregnancy. This underscores the significance of discussing and considering OOC as part of the treatment plan for endometriosis patients, especially those at risk of ovarian compromise due to the disease or its management. The decision to pursue fertility preservation through OOC should be made on a case-by-case basis, taking into account various factors such as disease severity, patient age, ovarian reserve, and treatment history. French guidelines recommend considering OOC for endometriosis patients with bilateral ovarian endometriomas larger than 3 cm or those with endometriomas on a single ovary. Initiating fertility preservation discussions early, preferably before surgical intervention, allows patients to make informed decisions regarding their reproductive future. It is crucial to acknowledge the challenges and uncertainties associated with fertility preservation in endometriosis patients. Socio-economic factors, patient preferences, and the lack of clear criteria for selecting candidates for OOC pose significant hurdles. Furthermore, the effectiveness and cost-effectiveness of OOC in this population warrant further investigation. In addition to OOC, alternative fertility preservation options, such as ovarian tissue preservation, could be considered, particularly in cases where ovarian stimulation is not feasible or declined by the patient. However, data on the efficacy and safety of ovarian tissue preservation specifically in endometriosis patients are limited, highlighting the need for further research in this area. In conclusion, fertility preservation, particularly through OOC, holds promise for mitigating the adverse effects of endometriosis on ovarian function and fertility. While uncertainties persist, integrating fertility preservation discussions into the comprehensive management of endometriosis is essential. This ensures that patients are empowered to make informed decisions about their reproductive health and maximizes their chances of achieving desired fertility outcomes despite the challenges posed by endometriosis.
