In this phase, the follicle from where the mature egg ruptures, releases some estrogen and a huge amount of progesterone. These hormones aid in the thickening of the lining of the endometrium, maintaining their thickness. In the event when fertilization does not take place, degradation of the yellow body occurs and the levels of progesterone decreases. This leaves the lining unstable. Then the lining drops away paving way for a new menstrual cycle period to begin.
