Eggs and follicles are two different concepts, the difference being that follicles contain eggs. The follicle gradually develops and grows from a small follicle to a large follicle, which contains a small egg. During the development of the follicle, the egg gradually grows and becomes larger, and the egg matures only after the follicle matures and is stimulated by follicle stimulating hormone. The follicle contains eggs, and as the follicle enlarges and the follicle develops to a certain point, the egg reaches its maximum diameter and does not grow any further. Women must be aware that there are factors in the physiological process such as endocrine factors that can affect the development of the follicles and affect the growth and quality of the eggs.
