It seems highly likely that regulation of DIO2 by TSHβ underlies seasonal cyclicity in both the reproductive and metabolic axes, indeed a recent study in Siberian hamsters maintained in short days has demonstrated that intracerebroventricular infusion of TSHβ increases body weight in addition to promoting testicular recrudescence (Klosen et al., 2013).
