Maturation of germ cells occurs in cycles. In both ovaries of a young woman, there are 400-500 eggs, but they mature one at a time, every 28 days. Each of the eggs is in a special vesicle – the follicle. When ripe, it fills with liquid and protrudes on the surface of the ovary. Soon, the follicle bursts, and the egg enters the abdominal cavity, and from there into the fallopian tube. This process is called ovulation.
