Which phase of the menstrual cycle is represented by "Ovulatory phase" in the FOL(d) M(a)PS mnemonic?

• A. First phase
• B. Mid-cycle phase
• C. Last phase
• D. None of the above

Answer: (B)

The ovulatory phase is indeed considered the mid-cycle phase of the menstrual cycle. This phase typically occurs about midway through the cycle, around day 14 in a standard 28-day cycle. During this time, a surge in luteinizing hormone (LH) triggers the release of a mature egg from the ovary, marking the point of ovulation.

This phase is critical for fertility as it represents the only time in the cycle when conception can occur; the egg is viable for fertilization for about 12-24 hours after its release. This is in contrast to the other phases of the menstrual cycle. The follicular phase happens beforehand, leading up to ovulation, while the luteal phase follows ovulation and is characterized by the preparation of the endometrium for a potential pregnancy. Understanding this helps in grasping the timing of ovulation and its implications for fertility.
