oocyte
Pre-ovulation reproductive cell
An oocyte is an immature egg cell in the ovary—the precursor to a mature ovum.
Oocytes develop through stages of cell division before becoming capable of fertilization.
The term appears in reproductive medicine and biology: The clinic retrieved twelve oocytes for IVF.
Human females are born with all the oocytes they will ever have.
