The uterine cycle describes a series of changes that occur to the lining of the uterus, or, endometrium, during a typical menstrual cycle. Learning Objective. Key Points. The uterine cycle includes the increase in the endometrium in preparation for implantation, and the shedding of the lining following lack of implantation, termed menstruation.
The endometrium is the lining of the uterus. It provides a fertile environment for a fetus to implant. Menstruation is the monthly shedding of the old endometrium, so that it can be replaced with a fresh layer that is optimal for a new fetus to have the opportunity to implant. The menstrual cycle consists of two phases. The first phase, under the influence of estrogen, is a proliferative phase. In other words, estrogen stimulates the endometrium to grow and thicken. While under this influence of the estrogen, the endometrium is called proliferative endometrium, because the cells are multiplying and the tissue is growing.
