The infantile ovary is filled with primordial follicles located in the cortex, just below the tunica albuginea.

The primordial follicles consist of a primary oocyte surrounded by a single layer of follicular cells.

Ovaries from an infant demonstrate a large number of primordial follicles in the cortex. There is no follicular development until the onset of puberty. Remember that all eggs are arrested in the first meiotic division. Meiosis I is completed prior to ovulation during the reproductive years.
