Estrogenic Regulation of the GnRH Neuron
Reproductive function is regulated by the secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary and the steroid hormones from the gonads.

Male reproduction is governed by the classical hypothalamo-hypophyseal testicular axis: Hypothalamic gonadotropin releasing hormone (GnRH), pituitary luteinizing hormone (LH) and follicle stimulating hormone (FSH) and the gonadal steroid, principally ...

Gonadotropins in the Russian Sturgeon: Their Role in Steroid Secretion and the Effect of Hormonal Treatment on Their Secretion. [PDF]
In the reproduction process of male and female fish, pituitary derived gonadotropins (GTHs) play a key role. To be able to specifically investigate certain functions of Luteinizing (LH) and Follicle stimulating hormone (FSH) in Russian sturgeon ...

Peripheral and central mechanisms involved in hormonal control of male and female reproduction [PDF]
Reproduction involves the integration of hormonal signals acting across multiple systems togenerate a synchronized physiological output. A critical component of reproduction is the luteinizinghormone (LH) surge, which is mediated by estradiol (E2) and ...

Ligula intestinalis (Cestoda: Pseudophyllidea): an ideal fish-metazoan parasite model? [PDF]
Since its use as a model to study metazoan parasite culture and in vitro development, the plerocercoid of the tapeworm, Ligula intestinalis, has served as a useful scientific tool to study a range of biological factors, particularly within its fish ...

Gonadotropin and kisspeptin gene expression, but not GnRH, are impaired in cFOS deficient mice. [PDF]
cFOS is a pleiotropic transcription factor, which binds to the AP1 site in the promoter of target genes. In the pituitary gonadotropes, cFOS mediates induction of FSHβ and GnRH receptor genes.

Action of the Metalloproteinases in Gonadal Remodeling during Sex Reversal in the Sequential Hermaphroditism of the Teleostei Fish Synbranchus marmoratus (Synbranchiformes: Synbranchidae) [PDF]
Teleostei present great plasticity regarding sex change. During sex reversal, the whole gonadincluding the germinal epithelium undergoes significant changes, remodeling, and neoformation.However, there is no information on the changes that occur within ...

Effect of gonadal steroid hormones on formalin‐induced temporomandibular joint inflammation [PDF]
AbstractWe have recently demonstrated that gonadal steroid hormones decrease formalin‐induced temporomandibular joint nociception in rats. Given that the attenuation of inflammation is a potential mechanism underlying this antinociceptive effect, we evaluated the effect of gonadal steroid hormones on formalin‐induced temporomandibular joint ...

Sexual differentiation of the rodent brain: dogma and beyond
Steroid hormones of gonadal origin act on the neonatal brain to produce sex differences that underlie adult reproductive physiology and behavior. Neuronal sex differences occur on a variety of levels, including differences in regional volume and/or cell
