CONTROL OF OVARIAN FUNCTION IN THE PRIMATE

本申请中描述的研究目标有两个： 阐明单个排卵卵泡成熟的机制， 周期，并确定灵长类动物的生理机制 黄体在恒河猴月经周期中受到调节。 本文提出的实验将研究所选卵泡是否 通过抑制促性腺激素来抑制其他卵泡的成熟 分泌，如果所选卵泡免于这种抑制， 它获得了丰富的脉管系统，这使得它能够优先 接受促性腺激素。 此外，本研究将定义 哺乳动物黄体对垂体促性腺激素的依赖性 月经周期的早期、中期和晚期黄体期，确定 黄体感知和响应垂体的性质 促性腺激素，并阐明了网站的作用，雌二醇在促进 黄体退化 除了提供关于生理学的明确信息外， 调节灵长类动物卵巢在体内，从这些获得的结果 实验可能会进一步加深我们对病理生理学的理解， 人类月经周期紊乱，例如卵泡生长受损， 黄体期短和黄体期不足。 最后是 越来越明显的是， 广泛用于治疗人类某些类型的闭经。 本申请中描述的研究将提供重要信息 关于促性腺激素释放激素（GnRH）驱动的月经中黄体的维持 周期，并在这样做，可以直接指导临床内分泌学家， 不孕症的有效治疗。

The goals of research described in this application are twofold: to elucidate the mechanisms by which a single ovulatory follicle matures each cycle and to identify the physiological mechanisms by which the primate corpus luteum is regulated during the rhesus monkey menstrual cycle. Experiments presented herein will investigate whether the selected follicle inhibits the maturation of other follicles by suppressing gonadotropin secretion, and if the selected follicle is spared from this inhibition by its acquisition of a rich vasculature which allows it to preferentially receive gonadotropins. In addition, this research will define the dependency of the primate corpus luteum on pituitary gonadotropins during the early, mid, and late luteal phase of the menstrual cycle, identify the nature by which the corpus luteum perceives and responds to pituitary gonadotropins, and elucidates the site of action of estradiol in promoting luteal regression. In addition to providing definitive information regarding the physiological regulation of the primate ovary in vivo, the results obtained from these experiments may further our understanding of pathophysiological disturbances of the human menstrual cycle such as impaired follicle growth, the short luteal phase, and the inadequate luteal phase. Lastly, it is becoming increasingly apparent that pulsatile GnRH treatment will be used extensively in the treatment of certain types of amenorrhea in humans. Studies described in this application will provide important information regarding the maintenance of the corpus luteum in GnRH driven menstrual cycles, and in doing so, may directly guide clinical endocrinologists in the effective treatment of infertility.
