What is the correct order of the menstrual cycle phases?

The menstrual cycle consists of several phases that occur in a specific sequence, essential for understanding female reproductive biology. The correct sequence begins with the follicular phase, where the follicles in the ovaries mature in response to hormonal signals. This phase prepares the body for ovulation.

Next is the ovulation phase, which is marked by the release of an egg from the dominant follicle, typically occurring around the midpoint of the cycle. This is a critical time for fertilization if sperm is present.

Following ovulation is the luteal phase, during which the remnants of the ruptured follicle transform into the corpus luteum. This structure produces hormones, mainly progesterone, which prepares the uterine lining for a potential implantation of a fertilized egg.

Finally, if fertilization does not occur, the menstrual phase begins. This phase involves the shedding of the uterine lining, leading to menstruation.

Thus, the correct order of the menstrual cycle phases is follicular, ovulation, luteal, and menstrual.
