Endometriosis (EMs) is a chronic, estrogen-dependent, multi-systemic disease that affects approximately 190 million women worldwide. EMs can increase the risk of miscarriage, and even mild EMs can negatively affect fertilization and implantation rates. Some meta-analyses have reported that EMs increases the risk of adverse obstetric outcomes, such as preterm birth and cesarean section, and also increases the risk of neonatal hospitalization. In addition to affecting pregnancy outcomes in women of reproductive age, EMs has significant social and psychological impacts on women of all ages in multiple areas of life, and can further affect the entire family, leading to substantial economic burdens and reduced quality of life. Finally, due to the increased incidence of the disease in the offspring of EMs patients, long-term follow-up is also a key aspect of disease management. To improve clinical practice and enhance fertility in EMs patients, more evidence is needed to meet the key priorities of future research. Integrated analysis of comprehensive case resources and clinical data can provide a reliable research foundation for future personalized diagnosis and treatment. High-quality and traceable large biobanks are a crucial resource for exploring pathogenic mechanisms. Prospective cohort studies conducted on this basis are expected to investigate the impact of the disease on patient clinical outcomes and further explore the disease's pathogenesis, aiming to identify physiological pathways influenced by the epigenome, transcriptome, proteome, and metabolome. ...
