Ovulation is specifically characterized by the release of an ovum from the graafian follicle, which is a mature ovarian follicle that has developed in response to hormonal changes during the menstrual cycle. This process occurs when there is a surge in luteinizing hormone (LH) that triggers the final maturation of the follicle, leading to the release of the ovum into the fallopian tube, where it can potentially meet sperm for fertilization.

Understanding this process highlights the distinction between ovulation and other events in the reproductive cycle. For instance, while the shedding of the uterine lining occurs during menstruation, it is not related to the event of ovulation itself. Similarly, fertilization of the ovum by sperm signifies a different stage in the reproductive process, following ovulation. Recognition of the role of the graafian follicle in releasing the ovum underscores its importance in reproductive physiology.
