Endometriosis

Essential facts Endometriosis is the presence of endometrial-like (womb lining) tissue outside the uterus, which induces a chronic, inflammatory reaction. Up to one in ten women and up to 50% of infertile women are believed to have the condition, which can be painful and debilitating. It can have a significant impact on quality of life, and on the lives of partners. Research has found that men are often marginalised in relation to endometriosis, with little information and support available.
