Definition of oogenesis in US English:



  • The production or development of an ovum.

    • ‘If X chromosome loss occurs during oogenesis, then some ova are expected to be nullo-X, which would result in a patroclinous non-Unc male.’
    • ‘The cytological processes of spermatogenesis and oogenesis are quite distinct.’
    • ‘This paradox can be explained by the occurrence of narrow bottlenecks during oogenesis or early embryo development.’
    • ‘It has long been known that most of the factors that are required during early embryogenesis are deposited into the egg cytoplasm during oogenesis and are maternally provided.’
    • ‘The genes we identified are involved in oogenesis, metabolism, and feeding behaviors, indicating a possible link to reproduction and survival.’
