Meiosis in a living crane fly spermatocyte [Meiosis II]
(The American Society for Cell Biology, ASBC Image & Video Library, 2016)
Selective advantage of euploid spermatocytes i in an azoospermic 47,XYY man with gonadal mosaicism
(Oxford University Press, 2019-03)
Although most XYY men have normal sperm counts and are fertile (supposedly due to the loss of the extra Y before meiosis), there is a minority who are infertile. In these cases, the XYY spermatocytes are able to enter ...
The ultrastructure of the pre-meiotic and meiotic stages of spermatogenesis in Plagioscion squamosissimus (Teleostei, Perciformes, Sciaenidae)
(2002-04-01)
Spermatogenesis of 'corvina' P. squamosissimus starts from a stem cell that gives rise to germ cells. These cells are enveloped by Sertoli cells, forming cysts. The germ cells in the cysts are all at the same stage of ...

Spermatogonia and spermatocyte ultrastructure in Hoplias malabaricus (Teleostei, Characiformes : Erythrinidae)
(Cambridge University Press, 2002-07-01)
The Hoplias malabaricus primary spermatogonium shows a large nucleus, central nucleolus, and low electron-dense cytoplasm containing nuages. In cysts, they undergo several mitotic divisions with incomplete cytokinesis, ...

Cytogenetic characterisation of Triatoma rubrofasciata (De Geer) (Hemiptera, Triatominae) spermatocytes and its cytotaxonomic application

The ultrastructure of Sorubim lima (Teleostei, Siluriformes, Pimelodidae) spermatogenesis: premeiotic and meiotic periods
(Churchill Livingstone, 1999-12-01)
The ultrastructure of Sorubim lima spermatogenesis during the premeiotic and meiotic periods was studied. Our observations showed that the germ cells in the cysts are connected by cytoplasmic bridges and the mitotic and ...
