During the menstrual cycle, the endometrium of the uterus thickens in preparation for a possible pregnancy. If fertilization does not occur, the endometrium sheds during menstruation. The uterus also contracts to help expel the menstrual blood.
The uterus lining changes in thickness during the menstrual cycle in response to hormonal levels.
