Aire, Tom A.; Ozegbe, P.C. (Elsevier, 2012-02)The fate of the proximal centriole in passeridan birds is an area of controversy and relative lack of knowledge in avian spermatogenesis and spermatology. This study examines, for the first time, spatiotemporal changes ...

Ozegbe, P.C.; Aire, Tom A.; Deokar, M.S. (2012-02)The cellular composition of the testicular capsule, seminiferous peritubular tissue, the epithelia as well as periductal muscle cell layers of the excurrent ducts was studied, in sexually mature and active Masked Weaver ...
-
Aire, Tom A.; Ozegbe, P.C. (Springer, 2008-08)The presence, location and degree of immunoexpression of various microfilament (MF) and intermediate filament (IF) systems (actin, cytokeratins, desmin, vimentin) were studied in the excurrent ducts of the testis in sexually ...

Elias, M.Z.J. (Mario Zefanias Joao); Aire, Tom A.; Soley, John Thomson (Blackwell, 2007-08)The macroscopic features of the arterial supply to the reproductive system of the male ostrich was studied in 16 pre-pubertal and eight sexually mature and active birds. The left and right cranial renal arteries arise from ...

Elias, M.Z.J. (Mario Zefanias Joao); Aire, Tom A.; Soley, John Thomson (Agricultural Research Council, ARC-OVI and the University of Pretoria, 2008-12)The macroscopic features of the venous drainage of the reproductive system of the male ostrich were studied in six pre-pubertal and three sexually mature and active birds. Each testis was drained by one to four testicular ...

Ozegbe, P.C.; Aire, Tom A.; Madekurozwa, Mary-Catherine; Soley, John Thomson (Springer, 2008-04)The testicular capsule and peritubular boundary tissue of the emu and ostrich, as typical representatives of ratite birds, were studied in sexually mature and active birds. The testicular capsule was much thicker (578.1±73.4 ...

Roopnarine, Narindra H.; Gupta, Sunil K.; Du Plessis, Lizette; Aire, Tom A. (Wiley, 2020-11)It remains a major concern that sperm structure has continued to be poorly investigated and reported in avian species. To our knowledge, sperm structure in the order Pelecaniforme has not been reported. Although McFarlane ...

Roopnarine, Narindra H.; Gupta, Sunil K.; Du Plessis, Lizette; Aire, Tom A. (Elsevier, 2021-02)Avian species comprise more than half of all vertebrates yet there is a dearth of information regarding spermatid development in this class of animals. This report of spermiogenesis in the cattle egret, Bubulcus ibis, is ...

Aire, Tom A.; Ozegbe, P.C.; Soley, John Thomson; Madekurozwa, Mary-Catherine (Blackwell, 2008-08)The epididymal duct unit, comprising the ductus conjugens, ductus epididymidis and ductus deferens, was studied histologically, ultrastructurally and immunohistochemically in five sexually mature and active birds. The main ...

Aire, Tom A.; Ozegbe, P.C. (Blackwell, 2007-06)The testicular capsule was studied histologically, morphometrically, ultrastructurally and immunohistochemically in the Japanese quail, domestic fowl, turkey and duck (all members of the Galloanserae). The testicular capsule ...

Harrylal, Crissy-Ann; Lensink, Antonia Vergina; Gupta, Sunil K.; Aire, Tom A. (Wiley, 2023-11)The purpose of this study is to describe, in detail, the ultrastructure of the infundibulum of the sexually mature and active female green iguana, Iguana iguana. The infundibulum of five iguanas was remarkably distinct ...
