N80: Endometriosis

N80.2: Endometriosis of fallopian tube

With endometriosis, tissue resembling the mucous membrane of the uterus grows outside of the uterus. Exactly why endometriosis occurs is not understood.

The uterus (womb) is located in the female pelvis and is lined internally with mucous membrane. This lining of the uterus thickens at the start of each normal menstrual cycle. It is then expelled when you have your period. This process is controlled by various sex hormones. Endometrial tissue is normally only found in the uterus.

The endometriosis tissue does not perform the usual tasks of the mucous membrane in the uterus. Various symptoms may arise as a result. For example, you may experience sharp pains during your periods. Periods may be more severe than usual, as well. You may experience pain during sex, or recurring abdominal pain. It may also be more difficult to conceive. It is also possible that you will have no symptoms at all.

Inside your fallopian tubes you have tissue resembling the mucous membrane of the uterus.

The two fallopian tubes go to the right and left of the ovaries towards the womb. They are like tubes and they transport the egg cells from the ovaries to the uterus.
