endometrium
The endometrium is the inner lining of the uterus, which is an organ in the female pelvis where a fertilized egg can implant and develop during pregnancy. Each month, the endometrium thickens in preparation for potential pregnancy by building new tissue and blood vessels. If fertilization does not occur, this lining is shed and expelled from the body through menstruation. The health and condition of the endometrium are important for fertility and overall uterine function. It is a dynamic tissue that constantly renews itself in response to hormonal changes throughout the menstrual cycle.
