Abstract
It was shown in male rats aged 2–2.5, 8–10, and 14–16 months that the inhibitory effect of the same dose (expressed per unit of body weight) of thyroxine on compensatory hypertrophy of the thyroid gland increases with age. It is postulated that the threshold of sensitivity of the hypothalamic-pituitary-thyroid system to homeostatic inhibition decreases with age.
