What does oogeny mean?
Oogeny is the biological process through which ova, or eggs, form in an animal's ovaries. It begins with female germ cells called oogonia, which grow and differentiate into oocytes. The oocytes undergo meiosis, a form of cell division that halves the number of chromosomes, and then complete maturation into ova capable of participating in fertilization. The term belongs to the technical vocabulary of zoology, reproductive biology, and medicine; many writers use the synonym oogenesis, which is often the more familiar form in scientific literature. Oogeny is also distinct from embryogenesis, the later process in which a fertilized egg develops into an embryo. Knowing the word can therefore clarify the reproductive sequence and help distinguish egg formation from subsequent embryonic development.
nounThe biological process by which ova, or eggs, are formed in an animal's ovaries. It includes the growth and maturation of female germ cells and the meiotic divisions that ultimately produce ova.
- The formation and development of ova or eggs within an animal's ovaries.
"During oogeny, developing germ cells undergo meiosis and maturation to become ova capable of fertilization."
"During oogeny, oogonia develop into oocytes that undergo meiosis and ultimately mature into ova."
"Disruption of oogeny can impair the production of functional eggs and consequently affect fertility."
Rare and uncommon; writers usually refer to different processes of oogeny or say “processes of egg formation.”
"The study compared the rates of oogenies in females under different temperature conditions."
Oogeny is nature's egg-making process, turning immature ovarian germ cells into ova through meiosis and maturation.

Where does oogeny come from?
Oogeny combines the combining form oo-, from Greek ōón meaning “egg,” with -geny, from Greek gennēin meaning “to produce” or genesis meaning “production” or “origin.” The term became established in zoological usage during the 19th century. Its relatives include oogenesis, ovum, and oocyte, all of which ultimately reflect the same Greek word for an egg.
How oogeny is actually used
A formal biological term used chiefly in zoology, physiology, reproductive biology, and related medical research. In general scientific writing, oogenesis is more common.
Easily confused with oogeny
Oogeny and oogenesis usually name the same biological process, although oogenesis is the more common technical term.
