The ovaries produce the female egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle.
The eggs are stored within follicles in the ovary. Within a woman's lifespan, large numbers of follicles and oocytes will be recruited to begin the growth and maturation process.
