In a condition known as endometriosis, endometrial cells are present in the uterine tubes and/or in the peritoneal cavity where they become established tissues. A major symptom of endometriosis is periodic pain. Why do you think this occurs?
What will be an ideal response?
The endometrial cells have receptors for the hormones estrogen and progesterone and respond to these hormones the same as they would if they were in the body of the uterus. Under the influence of estrogen, they proliferate at
the beginning of the menstrual cycle and begin to develop glands and blood vessels, which then further develop under the control of progesterone. This dramatic change in tissue size and characteristics interferes with neighboring tissues by pressing on them or interrupting function in other ways. It is this interference that causes the periodic painful sensations.
