Characterization of gonadotropic cells during continuous and seasonal spermatogenesis of two freshwater fish species: a histochemical and immunohistochemical study
(2017-02-01)
This work describes gonadotropic (GtH) cells and their morphological and immunohistochemical changes during the spermatogenic cycle of Serrasalmus maculatus (continuous spermatogenesis) and Pimelodus maculatus (seasonal ...
Primordial germ cells (spermatogonial stem cells) of bullfrogs express sex hormone-binding globulin and steroid receptors during seasonal spermatogenesis
(2013-01-01)
In vertebrate species, testosterone seems to inhibit spermatogonial differentiation and proliferation. However, this androgen can also be converted, via aromatase, into estrogen which stimulates spermatogonial differentiation ...

Testosterone-immunopositive primordial germ cells in the testis of the bullfrog, Rana catesbeiana
(Blackwell Publishing, 2005-06-01)
In amphibia, steroidogenesis remains quiescent in distinct seasonal periods, but the mechanism by which spermatogenesis is maintained under low steroidogenic conditions is not clear. in the present study, testosterone ...

IGF1 regulation of BOULE and CDC25A transcripts via a testosterone-independent pathway in spermatogenesis of adult mice
(Inst Animal Reproduction Food Research, 2015-03)
The Deleted in AZoospermia (. DAZ) gene family plays an essential role in spermatogenesis and fertility in mammals. This gene family contains two autosomal genes, BOULE and DAZL (. DAZ-. Like), and the DAZ gene cluster in ...
