The oxygen consumption of castrate male rats is lower than that of normal, but higher than that of thyroidectomized rats. In castrate-thyroidectomized rats it is not lower than that found in non-castrate thyroidectomized rats. Treatment with methyltestosterone, within the conditions of these experiments, did not affect the metabolic rate of non-castrate animals, nor that of castrates. It caused a moderate increase in thyroidectomized-castrate rats. The latter rats showed also an increased sensitivity to treatment with thyroid, which, however, was neither caused nor influence by methyltestosterone. |
