Resumo: The histologic structure of the tubullar seminiferous epithelium and gonadosomatic index averages of domestic quail of the italian variety verified in all the seasons of the year was characterised that the spermatocytogenesis in this bird with a constant rhythm during the spring, the more active phase of the annual testicular cycle, and also the spermatogenesis did not stopped in the winter and summer, respectively. A quiescent phase of the cycle was observed from the beginning to the medium autumn in which the spermatogenesis was incomplete concerning the spermiogenesis, with consequent absence of spermatozoa formation. These features had an annual recurring pattern, which allowed to characterise a circannual cyclic rhythm to the quail's testis concerning to the spermatogenesis kinetics.

Por outro lado, uma fase quiescente do ciclo observou-se nos períodos inicial e médio do outono, quando a espermiogênese não se completava, levando à não formação de espermatozóides. Os eventos morfológicos testiculares observados parecem se repetir anualmente, durante as estações, sendo bem típica a quiescência outonal, o que permitiu caracterizar na codorna um padrão testicular cíclico circanual, em termos do ritmo da cinética da espermatogênese.Universidade de São Paulo.
