The endometrium is functionally subdivided into two layers. 1  The stratum functionalis is a thick superficial layer that is sloughed off during menstruation and grows anew during each cycle.  The stratum basalis consists of permanent stromal tissue and deep ends of the uterine glands.
At the beginning of the follicular phase, the lining of the uterus (endometrium) is thick with fluids and nutrients designed to nourish an embryo. If no egg has been fertilized, estrogen and progesterone levels are low. As a result, the top layers of the endometrium are shed, and menstrual bleeding occurs.
