The cells in the ovary are able to make hair, teeth, and other growing tissues that become part of a forming ovarian

Polycystic ovaries. The eggs mature within the follicles, or sacs, but the sac doesn't break open to release the egg. The cycle repeats, follicles continue to grow inside the ovary, and cysts form. For more information about polycystic ovaries, refer to our FAQ on Polycystic Ovarian Syndrome.
