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.
A woman becomes pregnant if the egg is fertilized by a man's sperm cell and attaches to the uterine wall. If the egg is not fertilized, it will break apart. Then, hormone levels drop, and the thickened lining of the uterus is shed during the menstrual period. Day 1 starts with the first day of your period. This occurs after hormone levels drop at the end of the previous cycle, signaling blood and tissues lining the uterus (womb) to break down and shed from the body.
