2. Figure 1
Germ cell attrition and follicular atresia according to Kaipia and Hsueh (1997). Germ cells migrate to the ovary during early embryonic development. Their number increases through mitotic divisions but most of the oocytes formed during development do not survive to the time of birth.

3. Figure 2
Classification of follicles in the human ovary. Growing follicles enter class 2 usually in the late luteal phase, class 3 between late luteal and early follicular phases, class 4 during late follicular phase and become recruitable class 5 follicles during late luteal phase. GC=granulosa cells; TIC=theca interna cells. From Gougeon (1996).
