An oocyte (UK /ˈoʊəsʌɪt/ US /ˈoʊ.oʊ.saɪt/) oöcyte ovocyte or rarely ocyte is a female gametocyte or germ cell involved in reproduction. In other words it is an immature ovum or egg cell. An oocyte is produced in the ovary during female gametogenesis. The female germ cells produce a primordial germ cell (PGC) that undergoes mitosis to form an oogonium. During oogenesis the oogonium becomes a primary oocyte.
