The endometrium is the inner lining of the uterus, playing a crucial role in the reproductive system. Each month, the endometrium thickens in preparation for a potential pregnancy, creating a nourishing environment for a fertilised egg to implant and develop into a foetus. If pregnancy does not occur, the top layer of the endometrium sheds during menstruation, and the cycle begins again.
In the context of fertility, the health and receptivity of the endometrium are vital for successful embryo implantation. Conditions such as a thin endometrial lining or endometriosis can negatively impact fertility, making it essential for women trying to conceive to ensure optimal endometrial function.
