Spermatogenesis occurs in males not onyl from May to July, but also in autumn. During winter, the testes were still filled with spermatozoa, with spermatogonia located in the wall of the lobules. Therefore the winter phase of quiscence is not folled by the depletion of the testes which remain full of sperm throughout the year |

Crivelli, 1981 |
| Cyprinus carpio |
Spermatogenesis was continuous and spermatogonia, psermatocytes, spermatids and sperm co-occurred in most testes throughout the spawning and non-spawning periods. Thus, males are euipped to spawn at any time during the year, but there is a defined gonadal cycle with a peak in Ig before the onset of spawning |
