Step-by-step solution

Initiation of oogenesis occurs during the embryonic development stage when millions of oogonia are formed within each fetal ovary (C-I). The first polar body is extruded when the primary oocyte completes its first meiotic division within the tertiary follicle, just prior to ovulation (A-II). The second polar body is extruded when the secondary oocyte completes its second meiotic division, which is induced by the entry of a sperm (B-III). The corpus luteum degenerates in the absence of fertilization, leading to a dr
