Definition of gonad in English:



Physiology Zoology
  • 1An organ that produces gametes; a testis or ovary.

    • ‘It is known as a gonadotrophic hormone as it affects the gonads (testes and ovaries) in mammals.’
    • ‘Fish were scored as intersexes when at least one of the gonads was an ovotestis or when one ovary and one testis were observed simultaneously.’
    • ‘Whether the gonads become ovaries or testes is determined by the chromosomes received from the parents at the time of conception.’
    • ‘As adults they lack appendages, segmentation, and all internal organs except gonads and the remains of the nervous system.’
    • ‘To compensate, internal organs such as the gizzard, gonads, and intestine may shrink.’
