Electrophysiological responses to different follicle-stimulating hormone isoforms on human cumulus oophorus cells: preliminary results

Abstract Objective The aim of the present study was to provide a better understanding of the specific action of two follicle-stimulating hormone (FSH) isoforms (β-follitropin and sheep FSH) on the membrane potential of human cumulus cells. Methods Electrophysiological data were associated with t...
