The endometrium is the inner lining of the uterus that undergoes cyclic changes throughout a woman’s menstrual cycle. It thickens in response to hormonal signals to create a suitable environment for embryo implantation. If fertilization and implantation do not occur, the endometrium sheds during menstruation.
A healthy and receptive endometrium is essential for a successful pregnancy, as it provides the necessary nutrients and support for the developing embryo.
