Journal Article
Effects of dietary magnesium on testicular histology, steroidogenesis, spermatogenesis and oxidative stress markers in adult rats.
TL;DR: The results suggests that the changes that occurred after excessive magnesium in testis were not for the enhanced adrenocortical activities or for the generation of oxidative stress in reproductive organs, but for the direct action of excess magnesium on male gonads.
Journal ArticleDOI
Excessive dietary calcium in the disruption of structural and functional status of adult male reproductive system in rat with possible mechanism
TL;DR: Overall observations suggest that excessive dietary calcium enhances the generation of free-radicals resulting in structural and functional disruption of male reproduction.
Book ChapterDOI
Stress and Reproduction in Amphibians
TL;DR: The chapter summarizes recent developments in understanding of the neural and endocrine pathways that mediate stressor effects on reproduction and the role of glucocorticoids in energy metabolism during reproduction in amphibians.
Journal Article
Dose-dependent effect of copper chloride on male reproductive function in immature rats
TL;DR: It is suggested that copper has got a dose-dependent effect on testicular steroidogenic enzyme activity and stimulation of testicular spermatogenesis and serum testosterone and LH level in maturing male rats.
Journal ArticleDOI
Effects of steroid hormones on spermatogenesis and GnRH release in male Leopard frogs, Rana pipiens.
TL;DR: This is the first study to report the direct measurement of GnRH secretion in a poikilothermic tetrapod and revealed potent but sometimes paradoxical effects of steroid hormones, especially E(2), on the reproductive regulation of the male R. pipiens.

Journal ArticleDOI
Direct inhibitory effect of glucocorticoids upon testicular luteinizing hormone receptor and steroidogenesis in vivo and in vitro.
TL;DR: The direct inhibitory effect of glucocorticoids on testicular LH receptor content and steroidogenesis is demonstrated, suggesting the adrenal glucocORTicoids may regulate testis functions.
Journal ArticleDOI
Purification of a 17β-Hydroxysteroid Dehydrogenase of Human Placenta and Studies on Its Transhydrogenase Function
TL;DR: Methods for the extensive purification of a soluble 17@-hydroxysteroid dehydrogenasel of human placenta are described, which appears to be responsible for the entire 17/3estradiol-mediated transfer of hydrogen between pyridine nucleotides in soluble extracts of this tissue.

Glucocorticoid-Mediated Repression of P450scc mRNA and de Novo Synthesis in Cultured Leydig Cells
Dale B. Hales,Anita H. Payne +1 more
TL;DR: The finding on the negative regulation of P450(17 alpha) protein synthesis by testosterone suggest that the steroidogenic P450 enzymes in Leydig cells are negatively regulated by steroid hormones acting via their cognate receptors.
