This pathology affects 1 in 10 women worldwide. Chronic pelvic pain is the main complaint of patients with endometriosis, which causes the most discomfort and has a strong impact on the quality of life. Today, the main generally accepted criterion for the severity of pain is the volume of the affected tissue, but most often it does not correspond to the real pain sensations of the patients. In this review of the literature, we have identified and compared the main pathophysiological mechanisms of the development of pain in endometriosis, which help to answer some urgent questions. We have identified 6 mechanisms that sequentially activate and reinforce each other's action, leading to the formation of persistent pain syndrome. There are still gaps in the pathophysiological mechanisms described by us, which requires additional clinical studies. A better understanding of the pathophysiology of pain in endometriosis will help improve diagnostic capabilities, as well as treatment that will be directed at each link in the pathological process.</p></abstract><trans-abstract xml:lang="ru"><p>Эндометриоз – хроническое заболевание, которое сопровождается хронической тазовой болью и бесплодием. Данная патология поражает 1 из 10 женщин во всем мире. Хроническая тазовая боль – основная жалоба пациенток с эндометриозом, которая доставляет наибольший дискомфорт и оказывает сильное влияние на качество жизни. На сегодняшний день основным общепринятым критерием тяжести болевого синдрома является объем пораженной ткани, но наиболее часто он не соответствует реальным болевым ощущениям пациенток. В данном обзоре литературы мы выделили и сопоставили основные патофизиологические механизмы развития болевого синдрома при эндометриозе, которые помогают ответить на некоторые актуальные вопросы. Мы определили 6 механизмов, которые последовательно активируют и усиливают действие друг друга, приводя к формированию стойкого болевого синдрома. В описанных нами патофизиологических механизмах по-прежнему имеются пробелы, что требует проведения дополнительных клинических исследований. Лучшее понимание патофизиологии боли при эндометриозе поможет улучшить диагностические возможности, а также лечение, которое будет направлено на каждое звено патологического процесса.</p></trans-abstract><kwd-group xml:lang="en"><kwd>endometriosis</kwd><kwd>pain syndrome</kwd><kwd>chronic pelvic pain</kwd><kwd>pathophysiology</kwd><kwd>mechanisms</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эндометриоз</kwd><kwd>болевой синдром</kwd><kwd>хроническая тазовая боль</kwd><kwd>патофизиология</kwd><kwd>механизмы</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Simoens S, Hummelshoj L, D'Hooghe T.
