The amount of immunoreactive TRH released into hypophysial portal blood of female rats was about 2 orders of magnitude greater than gonadotropin releasing hormone and somatostatin. The turnover of TRH, as high as 80% of the total hypothalamic content per hour, was also much greater than that of any other known peptide. TRH release increased during the expected proestrous surge of prolactin and also in some animals during suckling.
释放到雌性大鼠垂体门脉血液中的免疫反应性促甲状腺激素释放激素（TRH）的量比促性腺激素释放激素和生长抑素大约高2个数量级。TRH的更新率高达每小时下丘脑总量的80%，也远高于任何其他已知肽。在预期的发情前期催乳素激增期间，TRH释放增加，在一些动物哺乳期间TRH释放也会增加。
