Which stage directly follows ovulation in the menstrual cycle?

Explanation:
Directly after ovulation comes the luteal phase. At this time, the ruptured follicle transforms into the corpus luteum, which secretes progesterone (along with some estrogen) to prepare and maintain the endometrium in case a fertilized egg implants. If pregnancy does not occur, the corpus luteum degenerates, progesterone levels fall, and the endometrium is shed during menstruation, starting the next cycle. The other phases are earlier: the follicular phase precedes ovulation, and menstruation occurs at the start of the cycle when the endometrium is shed. Ovulation itself is the release of the egg, not a subsequent phase.
