摘要:In this issue, three articles have focused on endometriosis classification and terminology (International Working Group of American Association of Gynecologic Laparoscopists (AAGL), European Society for Gynaecological Endoscopy (ESGE), European Society of Human Reproduction and Embyology (ESHRE) and World Endometriosis Society (WES), 2021a; International Working Group of AAGL, ESGE, ESHRE and WES, 2021b; Hudelist et al., 2021). These articles touch on different aspects of the topic but they all have a common message: a universally accepted endometriosis “language” is urgently needed. A language that will unify us on terminology we use as well as on the way we describe and classify endometriosis in its various phenotypes and severity.
