What is the role of the Graafian follicle in the menstrual cycle?

The Graafian follicle plays a crucial role in the menstrual cycle as it is responsible for releasing the mature ovum during ovulation. As the dominant follicle in the ovary, it undergoes maturation, reaching a stage where it is ready to be released. This process is triggered by hormonal signals, particularly luteinizing hormone (LH), which causes the follicle to rupture and release the ovum into the fallopian tube. This event marks a pivotal moment in the menstrual cycle, as it indicates the potential for fertilization and subsequent pregnancy.

While the other options mention functions that relate to aspects of reproductive health, none directly align with the primary role of the Graafian follicle, which is fundamentally about ovum release.
