Many theories exist to explain why endometriosis causes infertility. Some suspect that endometriosis is linked to an idiosyncrasy in a woman’s immune system that creates an autoimmune disorder, or makes the woman more likely to miscarry. Others believe irregular hormone levels in women with endometriosis contribute to infertility.
One cause that nearly all physicians can agree on is mechanical dysfunction. This occurs when endometriosis and its subsequent adhesions attach to the delicate structures of the reproductive tract. Endometriosis adhesions may attach to one or both ovaries, causing ovulation pain or decreasing their ability to release an egg. Adhesions can block fallopian tubes in two ways – by squeezing them closed from the outside or blocking the tubes from the inside.
     Endometriosis located on or near the uterus can cause uterine spasm or painful periods, decrease the opportunity for implantation or cause miscarriage. Endometriosis which attaches to the nearby bowels may cause painful bowel movements or chronic intestinal pain. In short, adhesions within the reproductive tract can cause cycle or intercourse pain, periods, pelvic or low back pain or dysfunction, including infertility.
