The first step in oogenesis is the division of a primary oocyte, which forms a secondary oocyte and a first polar body. This occurs during meiosis I, which is completed at the time of ovulation. The secondary oocyte then completes meiosis II only if it is fertilized by a sperm. If it is not fertilized, it will disintegrate. The follicle becoming a corpus luteum and the transformation of a corpus luteum into a corpus albicans occur after ovulation and are not the first step in oogenesis.
