Emerging Perspectives on Gonadotropin Regulation in Vertebrates Revealed by the Discovery of FSH‐RH in Teleosts

BioEssays, EarlyView.
Regarding pituitary gonadotropin regulation, recent studies have shown that in mammals, FSH and LH are regulated by a single GnRH (solo GnRH model), whereas in teleosts, they are regulated by CCK (FSH‐RH) and GnRH (LH‐RH), respectively (dual GnRH model).

Gonadotropin Gene Modulation by Steroids and Gonadotropin-Releasing Hormone1 [PDF]

Biology of Reproduction, 1996
Physiological gonadotropin levels are modulated by complex interrelationships between the sex steroids and the hypothalamic GnRH pulse generator, and the steroids and GnRH individually regulate gonadotropin subunit (alpha, LH beta, FSH beta) gene expression.

Interspecific comparisons of anuran embryonic epidermal landscapes and energetic trade‐offs in response to changes in salinity

Developmental Dynamics, EarlyView.
Abstract Background Freshwater salinization is an emerging stressor in amphibian populations, and embryonic stages are most vulnerable. To better understand the variation in embryonic osmoregulation, we challenged embryos of two phylogenetically diverse anuran species, Xenopus laevis and Lithobates (Rana) sylvaticus, along a gradient of non‐lethal ...

Review of the safety, efficacy, costs and patient acceptability of recombinant follicle-stimulating hormone for injection in assisting ovulation induction in infertile women [PDF]

, 2009
Anovulation is a common cause of female subfertility. Treatment of anovulation is aimed at induction of ovulation. In women with clomiphene-citrate resistant WHO group II anovulation, one of the treatment options is ovulation induction with exogenous ...
