Metrium

Metrium refers to the lining of the uterus, specifically the endometrium. This tissue plays a crucial role in the reproductive cycle of female mammals. The endometrium undergoes cyclical changes in response to hormonal fluctuations, primarily estrogen and progesterone. During the menstrual cycle, the endometrium thickens and becomes more vascularized, preparing the uterus for the potential implantation of a fertilized egg. If pregnancy does not occur, the outer layers of the endometrium are shed, resulting in menstruation. If fertilization and implantation are successful, the endometrium continues to develop, supporting the growth of the embryo and fetus throughout pregnancy. Conditions affecting the metrium include endometriosis, where endometrial-like tissue grows outside the uterus, and endometrial hyperplasia, a condition characterized by excessive thickening of the uterine lining. Medical interventions for metrium-related issues often involve hormonal therapies or surgical procedures.
