Definition

The endometrium is the inner lining of the uterus. The uterus is a female reproductive organ and its inner wall is used to receive a fertilized egg so that it can grow. If there is no fertilization, the endometrium necrotizes. This necrosis is what causes menstrual blood flow. The endometrium is under hormonal influence and develops thanks to a hormone secreted by the ovaries, estrogen. After menstruation, estrogen secretion promotes the thickening of the mucosa, and the absence of fertilization generates the stop of this hormonal impregnation and the destruction of the endometrium.
