Complications

Endometriosis is a chronic disease that is difficult to diagnose and to treat. Without treatment, endometriosis gets progressively worse in 65 - 80% of patients. Even with treatment, endometriosis continues to advance in 20% of patients. Cysts and implants may grow and spread to other parts of the pelvis, and in very severe cases, to the urinary or intestinal tracts. Eventually adhesions may form. These are dense, web-like structures of scar tissue that can attach to nearby organs and cause pain, infertility, and intestinal obstruction.

Pain

Pain is the most common complaint for women with endometriosis, and it can significantly impair the quality of life. The pain experienced around menstruation can be so debilitating that up to 25% of women with the condition are incapacitated for 2 to 6 days of each month. In severe cases, regular activities may be curtailed for up to 2 weeks per month. Sleeping problems have been reported in75% of patients, mostly due to pain.

Infertility

Endometriosis may account for as many as 30% of infertility cases. Some evidence suggests that between 30 - 50% of women with endometriosis are infertile. Often, however, it is difficult to determine if endometriosis is the primary cause of infertility, particularly in women have mild endometriosis. In an attempt to determine the chances for infertility with endometriosis, researchers have come up with a staging system based on findings during diagnostic surgery.

Endometriosis rarely causes an absolute inability to conceive, but it can contribute to infertility both directly and indirectly.

Direct Effect of Endometrial Cysts. Endometrial cysts may directly prevent infertility in a number of ways:

If implants occur in the fallopian tubes, they may block the egg's passage.
Implants that occur in the ovaries prevent the release of the egg.
Severe endometriosis can eventually form rigid webs of scar tissue (adhesions) between the uterus, ovaries, and fallopian tubes, thereby preventing the transfer of the egg to the tube.
