As the follicle develops, it produces key hormones, primarily estrogen, which plays an essential role in the regulation of the reproductive process, including promoting the growth of the uterine lining in preparation for a possible pregnancy.

This hormonal secretion is vital for coordinating the menstrual cycle and triggering ovulation when the mature egg is released. The follicular phase of the menstrual cycle is marked by the growth and maturation of these follicles, leading up to ovulation when one or more follicles rupture to release the eggs.

Preventing ovulation is not a direct function of follicles; rather, it is influenced by other
