Abstract

Experiments on pubertal male rats have shown a decrease in the mean frequency of neuronal impulse activity of arcuate hypothalamic nuclei 1 hour after intramuscular injection of oily solution of testosterone propionate. This is one of the possible mechanisms of decreased liberin-producing function of arcuate nuclei, that underlies the negative feed-back control of male sex glands.

摘要

对青春期雄性大鼠的实验表明,肌肉注射丙酸睾酮油溶液1小时后,下丘脑弓状核神经元冲动活动的平均频率降低。这是弓状核促释放素分泌功能下降的可能机制之一,而弓状核促释放素分泌功能下降是男性性腺负反馈控制的基础。
