An "ootid" is the haploid result of ootidogenesis. Thus, the time spent as an ootid is measured in minutes. It can be an oogonium, an oocyte, or an ootid. The succeeding phase of ootidogenesis occurs when the primary oocyte develops into an ootid. When meiosis II has completed, an ootid and another polar body have now been created. The ootid matures into an ovum.
