This surprising connection between taste and male fertility occurred when the gene encoding the taste receptor proteins TAS1R3 (part of savory taste receptor) and GNAT3 (converts oral taste signal to a nerve signal) were modified in mice allowing for selective knockout with the drug clofibrate. When these genetically modified mic…
