体外受精胚胎移植(IVF-ET)工作中着床率低是突出的问题。决定着床的因素主要是胚胎的质量及子宫内膜环境。后者由黄体进行调节。文献上关于促超排卵周期中抽吸卵泡后黄体功能的研究结果不一致。黄体期可正常或缩短。血孕酮(Po)浓变可正常,但6～13%呈低减。临床上皆用 Po或 hCG 支持黄体功能。本文对70个 IVF-ET 周期研究了与黄体期过短有关的因素。70例患者不育原因为输卵管因素,内膜异位症或原因不明。其自然周期黄体期不短。以氯菧酚(CC)及人绝经期促性腺激素(hMG)促超排卵,周期第7天起以 B 超声扫描及血雌二醇(E_2)、
In vitro fertilization embryo transfer (IVF-ET) work in the low rate of implantation is a prominent issue. The main factors that determine implantation are the quality of the embryo and the endometrial environment. The latter is regulated by the corpus luteum. Literature on the promotion of ovulation follicles in the superovulation cycle luteal function results are inconsistent. Luteal phase may be normal or shortened. Blood progesterone (Po) concentration can be normal, but 6 to 13% showed a decrease. Clinically, both luteinizing function is supported by Po or hCG. In this paper, 70 IVF-ET cycles were studied with the factors related to the luteal phase too short. 70 cases of infertility due to tubal factors, endometriosis or unexplained. The natural cycle luteal phase is not short. Ovarian hyperstimulation was induced by chlorophenol (CC) and human menopausal gonadotrophin (hMG). On the 7th day of the cycle, B ultrasound and E_2,
