Female Reproductive System. From the top of the uterus extend the fallopian tubes, which lead backward and downward to the ovaries. These are the two small sacs that contain the eggs. A woman is born with about 400,000 eggs. Each month during her reproductive years, usually only a single egg, or ovum, matures.The egg matures inside a follicle within an ovary.
