Irregular ovulation: Ovulation is necessary to have normal spontaneous menstrual periods. After ovulation the hormone Progesterone rises; if no pregnancy occurs, Progesterone falls and a period begins. In anovulation there is no Progesterone rise: menstruation cannot occur, so periods are irregular or absent altogether.
