Which sequence lists the four stages of the menstrual cycle in order?

• A. Ovulation, Follicular, Luteal, Menstruation
• B. Follicular, Ovulation, Luteal, Menstruation
• C. Menstruation, Follicular, Ovulation, Luteal
• D. Luteal, Menstruation, Follicular, Ovulation

Answer: (B)

The cycle starts with the shedding of the uterine lining, which is menstruation. After that, the ovaries enter the follicular phase, during which follicles mature and estrogen rises to rebuild the endometrium. Mid-cycle, an LH surge triggers ovulation, releasing the egg. The luteal phase follows, with the corpus luteum producing progesterone (plus some estrogen) to maintain the prepared lining. If pregnancy doesn’t occur, hormone levels fall and menstruation begins again. So the four stages in order are menstruation, follicular, ovulation, and luteal. Sequences that place menstruation elsewhere don’t align with how the cycle is traditionally counted.
