What is endometrium?

In brief: Endometrium

During the menstrual cycle the lining of the womb, known as the endometrium, gradually thickens and fills with blood as it prepares for the arrival of a fertilised egg.
If the egg is not fertilised, the womb lining breaks down and is lost as the monthly period. Sometimes small pieces of endometrium grow on organs outside the uterus. This is called endometriosis.
