The ovarian cycle is the series of changes that occur in the ovary during the menstrual cycle that cause maturation of a follicle, ovulation, and development of the corpus luteum.
This diagram of the ovarian cycle shows the cortex, primary follicle, developing follicle, ovum, mature follicle, fluid-filled cavity, ruptured follicle, ovulation, corpus luteum, and degenerating corpus luteum.
