An oocyte (/ ˈ oʊ ə s aɪ t /, 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 ...
Oocytes are immature egg cells that develop to maturity within a follicle in the ovary. Oocyte abnormalities can occur due to several factors, including premature ovarian insufficiency (POI), other maturation abnormalities, maternal ageing, and mitochondrial abnormalities.
Ovulation is an important part of the menstrual cycle in female vertebrates where the egg cells are released from the ovaries as part of the ovarian cycle. In female humans ovulation typically occurs near the midpoint in the menstrual cycle and after the follicular phase. Ovulation is stimulated by an increase in luteinizing hormone (LH).

At birth, female babies have around 1 to 2 million oocytes, and roughly 1,000 immature eggs are lost each month after the first period. In their late 30s, most women have about 25,000 oocytes ...
An immature ovum is a cell that goes through the process of oogenesis to become an ovum. It can be an oogonium , an oocyte , or an ootid . An oocyte, in turn, can be either primary or secondary, depending on how far it has come in its process of meiosis .
The egg cell or ovum (pl.: ova) is the female reproductive cell, or gamete, [1] in most anisogamous organisms (organisms that reproduce sexually with a larger, female gamete and a smaller, male one). The term is used when the female gamete is not capable of movement (non- motile ).
Gameto's process involves extracting immature eggs from a woman's body and then using "engineered, young ovarian support cells to recreate the natural egg maturation process in a laboratory setting."
