The female produces eggs from primordial germ cells that have entered her genital ridges during embryonic development. The process of egg formation thus begins in the embryo and continues into the adult. In this chapter, we will first examine the structure of the female anatomy finally focusing in upon the ovaries where oogenesis (egg formation) occurs. We will examine the development of the egg follicle and the layers of cells and extracellular material that surrounds the egg prior to ovulation. We'll then quickly remind you about the important role of hormones in the reproductive cycle of females, a topic that is covered in detail in physiology books. The role of hormones in sexual maturation and reproduction is not covered in detail in this book.
