Oogenesis
[Gr. oon - an egg; Gr. genesis - origin, descent] The process in females whereby a mature ovum is formed from an oocyte.

Oogenesis
Egg formation takes place in the ovaries.
In contrast to males, the initial steps in egg production occur prior to birth. Diploid stem cells called oogonia divide by mitosis to produce more oogonia and primary oocytes.
Oogenesis
The ovary contains many follicles composed of a developing egg surrounded by an outer layer of follicle cells. Each egg begins oogenesis as a primary oocyte.
Oogenesis
Oogenesis occurs in the ovary.
Each of the divisions in humans is unequal. During the first meiotic division, a large secondary oocyte and a small polar body are produced.

oogenesis The process by which an egg cell forms from an oocyte.
oogenotop Female genital complex of a flatworm, including oviduct, ootype, Mehlis' glands, common vitelline duct, and upper uterus.
During oogenesis, cytoplasmic bridges called "ring canals" connect the forming oocyte to nurse cells. Nutrients and developmental control molecules move from the nurse cells into the oocyte.

cells develop initially from germ stem cells known as spermatogonia . As these differentiate they become spermatocytes, spermatids (after meiosis) and then finally the fully mature spermatozoa. The female counterpart to spermatogenesis is oogenesis.
