European Journal of Obstetrics & Gynecology and Reproductive Biology, 2004 Ovarian stimulation is an important step in the success rate of in vitro fertilization (IVF) allowing multiple follicular growth, several oocytes and consequently more embryos. The combination of GnRH-antagonists (GnRH-ant) and gonadotrophins is now available for clinical use and represent a valid alternative to classical protocol with GnRH agonist ...

A role for GABA agonist in controlling the reproduction of female rats via hypothalamic ghrelin, kisspeptin, and RFRP-3 gene expression [PDF]
The Iranian Journal of Veterinary Science and Technology, 2021 Kisspeptin stimulates gonadotropin releasing hormone (GnRH). The GnRH neurons receive inhibitory inputs from ghrelin, RFamide related peptide-3 (RFRP-3), and gamma-aminobutyric acid (GABA) neurons.

Gonadotropin and kisspeptin gene expression, but not GnRH, are impaired in cFOS deficient mice. [PDF]
, 2015 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.

GnRH agonist triggering: recent developments [PDF]
Reproductive BioMedicine Online, 2013 The concept that a bolus of gonadotrophin-releasing hormone agonist (GnRHa) can replace human chorionic gonadotrophin(HCG) as a trigger of final oocyte maturation was introduced several years ago. Recent developments in the area strengthen this premise.
