What are the stages of the menstruation cycle?

Dr. Jeanne Morrison, PhD
Family Practitioner

The menstruation cycle is controlled by the release and interactions of hormones that are directly related to a woman's reproductive cycle. The menstruation cycle begins with the bleeding from the shedding of the uterine wall. This is the beginning of the follicular phase when the hormone which stimulates the ovarian follicles increases and one follicle, which holds an egg, develops. Estrogen levels increase. When the luteinizing hormone increases, ovulation is triggered and the ovulatory phase begins. As the follicle and luteinizing hormones decrease, the luteal phase begins marking formation of the corpus luteum, which produces progesterone. During the luteal phase, the uterine lining thickens and prepares for egg fertilization. If no fertilization occurs, the lining is shed and the next menstruation cycle begins.
