Gonadotropin-releasing hormone (GnRH) and its agonistic analogs inhibited the follicle-stimulating hormone (FSH)-induced increase of estrogen and progesterone production in vitro by rat ovarian granulosa cells. Likewise, GnRH analogs inhibited FSH-induced changes in ovarian function in hypophysectomized rats in vivo. These results indicate that GnRH, in addition to its well-known gonadotropin-releasing action in the pituitary, exerts a direct inhibition of ovarian steroidogenesis.
促性腺激素释放激素(GnRH)及其激动剂类似物在体外抑制了大鼠卵巢颗粒细胞中促卵泡激素(FSH)诱导的雌激素和孕酮生成增加。同样,GnRH类似物在体内抑制了垂体切除大鼠中FSH诱导的卵巢功能变化。这些结果表明,GnRH除了在垂体中具有众所周知的促性腺激素释放作用外,还对卵巢类固醇生成发挥直接抑制作用。
