Aim: To analyze modern approaches to the diagnosis and treatment of genital endometriosis. Key points. Endometriosis is one of the most common gynecological diseases, affecting mainly women of reproductive age, the main manifestations of which are chronic pelvic pain and infertility. Constant pelvic pain, which reduces the quality of life, leads to the fact that patients are in a state of prolonged stress, and they have behavioral disorders. According to the latest world recommendations, drug treatment is the first line of therapy for endometriosis, if pregnancy is not a priority at this stage. There are many imaging methods for diagnosing this disease, but the search for non-invasive markers of endometriosis that can reliably confirm the diagnosis is still ongoing. Conclusion. An interdisciplinary approach and the choice of adequate treatment for endometriosis at each stage of a woman's life can limit unnecessary surgery and better meet the needs of patients. Keywords: endometriosis, adenomyosis, chronic pelvic pain, progestins, dienogest, endometriosis markers.
