Endometriosis significantly impacts the physical and mental health of women of reproductive age. While some patients can achieve pregnancy through surgery or in vitro fertilization (IVF), many still struggle with IVF failure due to poor oocyte quality. This presents a major clinical challenge that requires immediate attention. The causes of oocyte quality decline in endometriosis patients are diverse and have not yet been definitively identified. Furthermore, effective diagnostic mechanisms and therapeutic strategies remain elusive. To provide possible clinical solutions to improve pregnancy rates in patients with endometriosis, this review evaluates the current literature on the impact of endometriosis on oocyte quality, the possible mechanisms and management strategies of endometriosis leading to poor oocyte quality.
