What is it?

Endometriosis is a condition where the uterine lining (endometrium) grows on pelvic structures outside the uterine cavity. In early-stage endometriosis there is usually little, if any, visible evidence of anatomical distortion sufficient to compromise the release of an egg (ovulation) or its transportation from the ovary to the fallopian tube. In contrast, advanced endometriosis is characterized by the presence of pelvic adhesions sufficient to distort normal pelvic anatomy and interfere with fertilization as well as egg/embryo transportation mechanisms. Women who have this condition are much more likely to experience infertility.
