explained

The tissue which lines the inside of the uterus is called the endometrium. In women of reproductive age (12 years – menopause) the tissue is broken down each month and shed as menstrual blood.
Endometriosis is a condition where the endometrium tissue is located in other sites of the body outside the uterus instead of being confined to the inside lining.

It is thought that this may happen for two reasons:

  1. Instead of the menstrual fluid flowing outside the body in the usual way, it flows back through the fallopian tubes.
  2. Patches of endometrium tissue may be deposited during the very early development of the reproductive organs.
