Definition of oocyte in English:



  • A cell in an ovary which may undergo meiotic division to form an ovum.

    • ‘The oocyte is then allowed to develop to the blastocyst stage in vitro.’
    • ‘However, in young women this comes at a price - many women lose ovarian function because oocytes or their support cells are damaged by the treatment.’
    • ‘In mammals, signals from the gonads determine whether the germ cells develop into oocytes or sperm.’
    • ‘Generally, this reflects a decline in the number of oocytes in the ovary (decreased ovarian reserve).’
    • ‘As semen quality reduces, the proportion of oocytes fertilised by in vitro insemination decreases.’
