SUMMARY

Thyroidectomy of intact and castrated rats produced significant reductions in their rates of sebum secretion. Replacement therapy with thyroxine (T4) increased the rate of sebum secretion of the castrated-thyroidectomized rats. Treatment with testosterone propionate also stimulated sebum secretion in castrated-thyroidectomized rats. When given together these two hormones had an additive effect on the rate of sebum secretion.

Thyrotrophic hormone (TSH) stimulated sebum secretion in castrated-hypophysectomized, but not in thyroidectomized rats.

It is concluded that TSH affects sebum secretion through its action on the thyroid, presumably by stimulation of T4 secretion.
