Introduction: FSH acts on its receptor (FSHR) resulting in signal transduction activation, gene expression and steroidogenesis. The FSHR common SNP p.N680S is a marker of gonadal response in vivo. However, in vitro dose–response experiments failed to demonstrate the molecular basis thereof so far. In this study, we systematically investigated whether p.N680S mediates different kinetics of FSH response in vitro.Des...

Human chorionic gonadotropin (hCG) is the pregnancy hormone marketed as a drug for assisted reproduction technologies to support follicle-stimulating hormone action. Several hCG formulations are commercially available, differing in source, purification methods and biochemical composition. In this study, we investigated the molecular features and the intracellular signaling mediated by five urinary and recombinant hCGs. The drug comparisons were performed by quantifying the hor...
