Oocyte - Wikipedia
An oocyte (UK: / ˈ oʊ ə s aɪ t /, US: / ˈ oʊ oʊ-/), 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.
13.62: Human Egg Cells - Biology LibreTexts
The primary oocyte resumes meiosis and divides to form asecondary oocyte and a smaller cell, called a polar body. Both the secondary oocyte and polar body are haploid cells. The secondary oocyte has most of the cytoplasm from the original cell and is much larger than the polar body. Maturation of a Follicle and Ovulation.

Oocyte | physiology | Britannica
gamete, sex, or reproductive, cell containing only one set of dissimilar chromosomes, or half the genetic material necessary to form a complete organism (i.e., haploid). Gametes are formed through meiosis (reduction division), in which a germ cell undergoes two fissions, resulting in the production of four gametes.

Oocyte - an overview | ScienceDirect Topics
An oocyte, as one of the largest cells in the body, is a female gametocyte for reproduction. It undergoes dynamic processes involving complicated regulatory mechanisms with various stages during the generation of oocyte and subsequent maturation and development.
