Endometriosis is when the cells that line the uterus or endometrium, grow in places outside the uterus (such as the pelvis). Around 10% of women of reproductive age are affected by endometriosis. It is quite a common condition, especially in women over 30 who have not yet had children. Endometriosis is a common cause of infertility, as severe endometriosis can distort the tubes and ovaries. It may also block the egg’s release by causing scar tissue or cysts.
