The ovary is one of the earliest organs in the body to undergo aging because the number of oocytes stored in the ovary is not sufficient for lifelong oogenesis.

WebAn example is the amphibian Xenopus laevis. In somatic cells, the ratio of nuclear DNA:mitochondrial DNA is 100:1. In the fully-grown oocyte, that ratio has reversed to a range from 1:1 to 1:100. During mitochondrial replication in early oogenesis, mitochondria cluster around the nucleus to form a structure called the mitochondrial cloud. WebThe formation of ova in the ovary from primordial germinal cells is said to be oogenesis. It is completed in three steps: (1) Multiplication phase: The germinal epithelium cells of the ovary multiply by mitotic divisions to form a small cluster of cells known as follicles.
