oocytes
Eggs before maturation
Oocytes are immature egg cells in the ovary, the precursors to mature ova.
In reproductive medicine, oocyte retrieval is a key step in IVF procedures: The clinic retrieved twelve oocytes.
The singular oocyte appears in technical contexts: a fertilized oocyte.
Pronounced OH-uh-site.
