WebNov 2, 2024 · As the first in the world, researchers from Aarhus University have found the molecular movements that take place in the very earliest eggs in the woman’s ovaries. In the long term, this discovery could help childless women who, despite fertility treatments, cannot become pregnant. An oocyte , oöcyte, or ovocyte 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 a female fetus in the ovary during female gametogenesis. The female germ cells produce a primordial germ cell (PGC), which then undergoes mitosis, forming oogonia. During oogenesis, the oogonia become primary oocytes. An oocyte is a form of genetic material that can be collected for cryoconservation.
