Verified step by step guidance1
Understand the ovarian cycle, which consists of the follicular phase, ovulation, and the luteal phase.
Recognize that the follicular phase is the first part of the cycle, where follicles in the ovary mature.
Identify that ovulation is the release of a mature egg from the surface of the ovary, typically occurring midway through the cycle.
Note that the luteal phase follows ovulation, where the corpus luteum forms and secretes hormones.
Recall that the luteinizing hormone (LH) spike is a key event that triggers ovulation, marking the transition from the follicular phase to ovulation.
