Endometriosis is an often painful condition characterised by the development of tissues similar to the lining of the womb outside the uterus. It often affects the ovaries, fallopian tubes and the tissue lining the pelvis.

Endometriosis can provoke pain, especially during menstrual periods, as well as fertility problems. Endometriosis significantly affects quality of life due to pain, fatigue, mental health issues, and infertility, often hindering daily activities, including work or school.

Its cause is unknown, as well as there is no known way to prevent this disease. There is no cure, but its symptoms can be treated with medicines or, in some cases, surgery.

Key facts (World Health Organisation):

• Endometriosis affects approximately 10% (190 million) of women and girls of reproductive age worldwide.
• There is currently no known cure for endometriosis and treatment is usually aimed at controlling symptoms.
• Early diagnosis and effective treatment are crucial, yet often limited, especially in low- and middle-income countries.
