What is endometrial stripe?

The endometrial stripe is composed of the lining of the uterus, also known as the endometrium. When a woman ovulates, the endometrial stripe thickens as the uterus prepares itself for the arrival of a fertilized egg. The stripe allows the right environment for the fetus to grow and become viable. Abnormalities in the endometrial stripe can also indicate the beginning signs of uterine cancer.
