which phase of the menstrual cycle is associated with fertility
Home â Your Fertility: Menstrual Cycle and Ovulation â Menstrual Cycle â Days 10-18: The Ovulatory Phase. The Ovulatory Phase of the menstrual cycle occurs in the middle of your menstrual cycle. An increase in the the luteinizing hormone (LH) level causes the mature follicle to burst and release the egg, usually around day 14. This is what is commonly called ovulation.
