The endometrium is a layer of tissue that lines the uterus, also known as the womb. It is a crucial component of the female reproductive system, playing a vital role in the menstrual cycle and pregnancy. The endometrium undergoes cyclical changes in thickness and composition in response to hormonal fluctuations, primarily influenced by estrogen and progesterone.

During the menstrual cycle, the endometrium thickens in preparation for potential fertilization. If an egg is not fertilized, the endometrium sheds during menstruation, resulting in a period. This shedding is mediated by the hormone progesterone, which causes the endometrium to break down and be expelled from the body.

In the event of fertilization, the endometrium continues to thicken to support the growing embryo and fetus. If pregnancy occurs, the endometrium provides nourishment and protection to the developing fetus. After childbirth, the endometrium regenerates to prepare for a potential future pregnancy.

The endometrium is composed of several layers, including the basal layer, which is attached to the myometrium (the muscular layer of the uterus), and the functionalis layer, which is the part that undergoes cyclical changes. The endometrium is rich in blood vessels and glands that secrete mucus, which helps to nourish and protect the embryo during pregnancy.

Any disruption in the normal functioning of the endometrium can lead to various gynecological conditions, such as endometriosis, uterine fibroids, and menstrual disorders. Understanding the role and structure of the endometrium is essential for diagnosing and treating these conditions.
