Both intact and ovariectomized + adrenalectomized hamsters on a short photoperiod, had a daily surge in plasma LH at approximately 16.00-18.00 h. The number of pituitary GnRH receptors was generally lower in ovariectomized + adrenalectomized hamsters than in intact animals, but both intact and ovariectomized + adrenalectomized hamsters had a decrease in the number of receptors just prior to the LH surge. These results show that gonadal steroids are not involved in regulating the pre-LH surge fall in the number of GnRH receptors.
在短光照周期下，完整的以及卵巢切除 + 肾上腺切除的仓鼠，其血浆促黄体生成素（LH）在每天大约16:00 - 18:00会出现一个峰值。卵巢切除 + 肾上腺切除的仓鼠垂体促性腺激素释放激素（GnRH）受体数量通常比完整动物的要低，但完整的和卵巢切除 + 肾上腺切除的仓鼠在LH峰值出现前受体数量均会减少。这些结果表明，性腺类固醇不参与调节LH峰值前GnRH受体数量的下降。
