Highlights ► Sex hormone effects on MR was different between male & female stripe-faced dunnarts. ► Sex hormone effects on torpor use was different between male & female dunnarts. ► Sex hormone effects on fattening was different between male & female dunnarts. ► This contrasts to other mammals where reproductive and torpor seasons are separate.
